Strength Training for Runners, Part 3: How?

So hopefully I’m persuading a few runners to try adding strength training to their regimen. Let’s go over some general strength training tips and the primary objectives to consider for the various muscle groups.

Strength training tips and objectives

1. Your primary goal is to place a stress on the body that it isn’t accustomed to and that, in some ways, exceeds the stress that running places on the body. This demand is what leads to positive adaptations.

  • Efficient running is stressful for the muscles, tendons, bones, joints, and other tissues in the body.

  • Inefficient running is even more stressful on many of these structures, which means you want to either get rid of the inefficiency (ideal) or make your body more tolerant of it (not ideal).

2. The progression should go as follows: mobility → skill → stability → endurance → strength → power

  • This means you need to master the basic movement pattern with a full range of motion far before you attempt to move heavy amounts of weight or move explosively.

  • Running requires tons of repetitions of a powerful movement yet many people don’t have the basic mobility and strength down to safely use that power.

3. Circuit train, especially if you aren’t accustomed to strength training yet.

  • Runners love to stay moving, so your earliest forays into strengthening can emphasize circuit training of the entire body. Circuit training allows you to move right from one exercise into another, bringing the heart rate up and providing a similar feel to the constant work of running that we crave.

  • Circuit training is more reasonable from a time-management perspective.

  • If you are new to strength work, alternate upper body, lower body, and core exercises to let each muscle region recover effectively in between exercises.

  • More experienced athletes can stack a single set of two or three similar exercises together to increase the muscle demand. For example, lunges followed by single leg squats and then on to step-ups.

  • You can add plyometric and agility drills throughout the strength session to keep the heart rate up and integrate running with speed, which is discussed next.

4. Integrate strengthening into your run workouts to improve your awareness of how to use those muscles while running.

  • Going back to circuit training, here’s one of my favorite winter activities when the weather is horrible and I must run inside:

    • Treadmill run 5 minutes

    • Hip strengthening and stability 1-2 minutes

    • Core strengthening and stability 1-2 minutes

    • Leg strengthening 1-2 minutes

    • Wash, rinse, and repeat for 45 to 90 minutes total

  • Perform a couple of bodyweight resisted exercises like leg raises or planks during your warm up to emphasize core and hip stability, strengthening, posture correction, and muscle awareness.

5. The abdominals (and actually some hip muscles) are primarily stabilizers when you run so learn to use them in that way.

  • Instead of crunches or sit-ups, use variations of planks and bridges.

  • Emphasize single leg activities with the pelvis held in a level position. I reviewed the pelvic position last week with the Trendelenburg's sign.

6. Work one side of the body at a time.

  • Symmetry in muscle strength is a key point. Working both sides of the body at the same time is less challenging and less productive because you will inevitably use a more dominant side without even realizing it.

7. Work multiple muscle groups simultaneously by emphasizing “closed chain” movements.

  • Closed chain implies the end of the leg or arm will be in contact with the ground or fixed object. Examples include squats, lunges, push-ups, step-ups, power cleans, planks, pull-ups, and most plyometrics like jumping and hopping.

  • Closed chain movements mimic running and normal daily activity. Open chain exercises, like leg extensions, do not often duplicate our day-to-day movement.

8. Think about performing exercises by the plane of movement that you move each joint through and then do a little work for each plane.

  • Squats and lunges emphasize a forward/backward plane at the knees and hips.

  • Single leg hip rotations emphasize a horizontal plane at the hips.

  • Pelvic drops emphasize a side-to-side plane at the hips and trunk.

9. When an exercise has become too easy, add an element to decrease stability and see if that doesn’t increase the difficulty.

  • For example, a standard front plank is easily advanced by lifting one leg, one arm, or both at the same time. The idea is to increase the wobble factor.

  • Some equipment options to increase instability include swiss balls, BOSU balls, and wobble boards.

  • Many standing exercises can be performed on a single leg to challenge the stability but you need to be proficient with their double-legged versions first.

10. Avoid using machines, emphasize free weights.

  • The limited range of motion keeps you from working in the positions that you actually need to gain usable strength.

  • Machines do not challenge the stabilizing muscles and nervous system components that can be beneficial for injury prevention and optimal performance.

  • Free weights are more likely to mimic the tasks that we perform in daily life because we commonly lift and move heavy objects.

11. Reduce strength training loads primarily in the week before your “A” races but not before “B” or “C” races.

  • Strengthening is part of the constant stimulus that you are trying to adapt to, so you don’t want to recover excessively before your low priority events. Train on through.

  • While training just before a low priority event you can decrease the number of repetitions in a set by 3-5 but keep the weight the same.

  • Before an “A” race, decrease both the sets, resistance, and repetitions if you have been working with resistances that cause failure at higher repetitions (i.e., do only 1-2 sets of 15-30 repetitions instead of 2-3 sets of 15-40 repetitions). If you have been gearing up with really high loads and performing more powerful, explosive moves, then back the sets down and the resistance only slightly (ie. do 2-5 sets of 3-8 repetitions instead of 5-6 sets of 3-8 repetitions).

12. Once your priority event has passed, back off of the rapid power and agility movements and encourage basic strength and strength endurance again for 2-4 weeks.

13. Perform strength training on shorter or less intense running days, especially if you have never strength trained before.

  • We don’t need too much of a good thing. Too much exercise stimuli in a day or series of days is a recipe for injury.

  • I often still use running as a brief warm-up before strengthening and, as mentioned, incorporate running drills throughout the strength workout.

  • Strength days are a great time to do other cross training on a bike, elliptical, rower, rock wall, or anything that allows you to experiment and break up the monotony of running.

14. A general initial strengthening structure could consider spending:

  • 50% of the time on the large primary movement muscle groups that undergo heavy use in running to improve overall movement strength and strength endurance.

    • These muscles, like the quadriceps, gluteus maximus, and hamstrings, can be pushed harder with higher resistances.

  • 25% of your time focusing on the muscle groups that are not dominant and become neglected in the running motion to prevent injury.

    • These muscles, like the deep gluteals, usually require very little resistance because they are not large or power producing.

  • 25% of the time integrating plyometric drills to increase power output, speed, and agility.

15. Allow at least 6-8 weeks of working at least 1x/week for noticeable performance changes.

In next week's blog I'll go over more application specifics and exercises.

Strength Training for Runners, Part 2: Why?

Why strength and plyometric train?

Why not strength and plyometric train? That’s a better question. My personal excuse is that it’s not as fun as running, partly because it’s not done outside and nowhere near the woods. I’d rather move me, not a dumbbell. Although I’m sure some would say by moving myself I am indeed moving a dumbbell. *Sigh*

For myself and many other runners, strengthening is a necessity if you want to run long, hard, or into old age. I will gladly give up 3-6 junk miles every week to take the time for this type of cross training. Strength training gets me to a point that makes the other runs more enjoyable. How does it improve my running enjoyment? Largely because I stay less injured overall, my back doesn’t hurt during long runs anymore, I recover quicker, and my legs never get that completely destroyed feeling in long races that they once did.

I would argue that running itself is a series of plyometrics. (The Merriam-Webster definition of a plyometric activity is “exercise involving repeated rapid stretching and contracting of muscles”). Plyometrics are just high speed strengthening.

Here are a few reasons runners should consider strength training:

1. Strength training improves performance. Every runner can benefit from strength training. Competitive trail runners, marathoners, and speed demons who compete at any distance could reap very significant gains. At the same time, the less competitive folks running just for fun could benefit too.

The mechanisms of improved performance can be attributed to any one or a combination of the following factors:

  • Increased hip and core stability
  • Increased force production of the muscle fibers (aka strength)
  • Increased fatigue resistance of the larger leg muscle groups (aka endurance)
  • Increased endurance of the core, hip, and leg muscle groups while producing greater force (aka strength endurance)

Increased hip and core stability

Having a strong core and hips takes unnecessary trunk motions out of the equation. You can then move the arms and legs more quickly and with greater force without disrupting the stable base. I noticed this in the 2016 women’s 10,000 meter U.S. Olympic trials. Molly Huddle maintains a very stable trunk posture. As a result, there is less energy wasted during the early and middle part of the run and that energy can be put to use in the closing laps. And at that point many of the competitors are flailing anyway.

 

Increased force production

As far as the prime movers of the legs go, if you want to move faster while running, your options are to:

  • increase turnover while maintaining the same muscle force output,
  • increase force from the muscles while maintaining the same turnover, or
  • increase both muscle force and rate of turnover.

Strength (and plyometric) training is a great way to teach your larger leg muscles to generate that force in an efficient manner. Many of the changes that we would refer to as increased strength are actually the result of the nervous system’s ability to refine how the muscle fibers fire. It’s definitely not all about making the muscles bigger. By increasing the ease and efficiency of force production, you can become faster.

Increased fatigue resistance of the larger leg muscle groups and increased endurance of the core, hip, and leg muscle groups while producing greater force

Greater total muscle strength can lead to greater strength endurance capacity. Strength endurance is concerned with the ability to generate a certain force for a prolonged period. In other words, after strength training for a few weeks I can make a muscle produce the same or greater force for a longer period of time before it begins to fail. This is a huge benefit if you have reached the limits of what your fast-twitch muscle fibers are willing to perform with standard running interval training techniques.

Racing and hard efforts can rely heavily on the fast-twitch muscle fibers, and slow endurance training does very little to train these muscle fibers because slow training is primarily using slow-twitch muscle fibers. You can only perform so much high intensity interval work while running so strength training is another way to stimulate these muscle fibers. By regularly training the fast-twitch muscle fibers, you can improve movement economy and improve fatigue tolerance. Better fast-twitch muscle fiber use will help you when bridging a gap in a race, moving at faster speeds, and climbing hills.

2. Strength training can help you prevent injury. There is research citing decreased injury incidence in athletes with consistent strength training routines (http://bjsm.bmj.com/content/early/2013/10/07/bjsports-2013-092538.abstract). Stretching, on the other hand, has no consistent research support in injury prevention. For one, as mentioned, proper strength training helps to increase hip and core stability so that the legs and arms are moving on a stable base. My theory would be that it’s mostly the strength, stability, and muscular endurance of the hips and core that help to keep a runner away from injury though it's certainly important to train the rest of the leg as well. This is where many runners have the wrong idea of what strengthening should really be about. The primary objective is to take the unnecessary motion out of the system in order to reduce the injury causing “slop.”

3. Strength training can help you recover from injury. Often, strengthening of specific muscles is a vital component of any patient’s injury recovery in my clinic. In the case of both injured and uninjured tissues, the intention is to rely on these primary concepts:

  • Improved structural integrity of muscle, tendon, ligament, and bone, and
  • Improved strength and neurological activity in weak muscles

4. Strength training changes your perspective on higher training intensities. If you can perform enough repetitions with a high resistance that you reach a point of true muscle failure, you begin to understand what it’s like to really push that extra bit of effort from yourself. That can make a finish line sprint or track workout feel a little easier, for the muscles at least.

5. Strength training helps decrease age-related strength loss. Aging causes a loss of the fast-twitch types of muscles fibers and their associated nerves. Frequently demanding work from those muscle fibers slows the rate of loss. Nobody wants to lose the strength necessary to do daily tasks but I assure you that it will happen if you let it. I didn’t think about this until I started approaching 40 years of age (and the girls stopped whistling at me.)

6. Increasing strength makes you a generally healthier individual and a well-rounded athlete. There’s nothing better than being able to confidently lift a 50-pound bag of potting soil from the ground without fear of hurting your back. And being able to randomly and confidently play a pickup game of {insert any sport here} is pretty awesome too.

7. Variety and changes in your training program prevent burnout and staleness. The same old, same old becomes dull and demotivating for most people. There is so much variety possible with strength and plyometric training that it can really freshen up your outlook.

8. Strength training can boost you through a performance plateau. The repetition associated with some endurance training programs will inevitably lead to a plateau in many athletes. In order to bust through the plateau you need a new type of training stimulus. Resistance training can be that stimulus if delivered correctly over a 4-8 week period of time, especially if you add the plyometrics and change up your running interval program.

Should you exercise while taking antibiotics?

Did you know that there are some prescription drugs that can have a negative impact on exercise capacity, recovery, and injury?

As if most of us didn’t already dislike taking antibiotics, now you might want to think about the documented exercise-related side effects from a specific family of antibiotics known as fluoroquinolones. These drugs have been associated with a risk of tendon rupture and tendon overuse injury.

Fluoroquinolones are frequently used to treat sinus infections, bronchial infections, and urinary tract infections, and work well against a large variety of bacteria. Which means many of us have taken these drugs.

Examples of these drugs include:

  • Levaquin (levofloxacin)

  • Cipro (ciprofloxacin)

  • Avelox (moxifloxacin)

  • Floxin (ofloxacin)

  • Factive (gemifloxacin)

Despite the consistently positive effects, in May 2016 the FDA made this statement available: “An FDA safety review has shown that fluoroquinolones are associated with disabling and potentially permanent, serious side effects that can occur together.  These side effects can involve the tendons, muscles, joints, nerves and central nervous system. As a result, the FDA is also requiring label changes for all systemic fluoroquinolone antibacterial drugs to reflect this new safety information.”

The FDA is not suggesting that doctors should stop prescribing these drugs. They are suggesting that they should not always be the first line treatment.

These side effects have been researched since 1996 (and one source documented tendon damage from the use of one of these drugs in 1983). Often the individuals begin to have tendinitis-like symptoms that quickly progresses to partial or full tearing of the involved tendons. Achilles tendon damage has been particularly well documented with tendinitis and ruptures.

Does this mean you will definitely have a torn tendon after taking these antibiotics? No. But as an individual with a more active lifestyle that heavily stresses your connective tissues, you should be aware and concerned if you begin to have tendon pain while taking or shortly after taking a course of these drugs.

Before taking these drugs, you may want to discuss the need for that particular prescription with your doctor, as you might qualify for another option. Should you begin taking these antibiotics while having an already existing tendon injury, be extra cautious with your activity for at least a month (negative effects have reported up to three months later). If you begin to have tendon pain while taking them, get in touch with your prescribing physician.

Having seen many patients who underwent surgical tendon repair procedures, a tendon rupture is not an injury that you want to deal with if it can be avoided. The likelihood of rupture is rare with 15-20 cases per 100,000 drug uses. If you must use that specific family of drugs be sure to monitor yourself, cut back on your exercise routine and talk to your physician if you should start to develop tendon region symptoms.

The information provided here is for informational purposes only. If you are concerned with your antibiotic use, seek further guidance from your primary care medical professional.

6 Deckers Creek Trail Half-Marathon Recovery Tips

Hope you had fun in the race. That last mile is brutal, right? Here are a few considerations to improve your recovery.

  1. Active recovery. At a minimum, go for a short walk. It can be slow and relaxed. If you are more experienced, going for a short run isn’t out of the question, of course. Going for a swim is a great choice too. Anyone with at least a couple months of training under their belt will feel better having performed active recovery - if it’s done correctly. It will take at least 10 minutes of activity to get to that point though.
  2. Avoid anti-inflammatory drugs. Inflammation gets a bad reputation because it’s usually accompanied by discomfort. But you need those processes to heal properly! Let your body do what it is meant to do in recovering from muscle soreness. Besides, over-the-counter anti-inflammatories are actually not very effective at improving the discomfort associated with delayed onset muscle soreness.
  3. Ice anything that seems like a new injury. Yes, inflammation has a good side. But a true new injury (besides muscle soreness) can have a little too much of that inflammation. Ice is nice to be able to spot treat anything that has flared up without having the systemic effects of medication. Ice now so these areas are not still an issue in three days.
  4. Regain normal hydration levels. It was hot and humid, so there is no doubt that you lost more fluid than you took in. Your urine shouldn’t be dark in color. It should be more like the color of a light beer. Drink 6-8 ounces of plain water every hour until you have achieved that level of hydration. If you have gastrointestinal discomfort at this point, then there’s a really high chance that your hydration levels are off.
  5. Gently perform muscle self-massage. Use a foam roller, massage stick, tennis ball, lacrosse ball, or even a rolling pin from your kitchen to roll up and down the full length of the thighs and lower legs. It doesn’t have to be highly uncomfortable but a little tenderness is fine. Try for 30 strokes on every side.
  6. Take a nap. Sleep is a great recovery method. The weather stinks today anyway. If you feel fatigued or drained then take advantage of a quick nap to boost your endocrine system’s output of healing hormones.

Does foot pronation increase risk of injury?

There is a misconception that certain structural features of the body are directly related to injuries. For years, people with lower arches were referred to as “pronators” and those with even flatter feet were “overpronators” or “hyperpronators.” They were all thought to have more injuries, and a portion of the shoe industry has really kept that mentality alive. The other two general foot types, neutral and supinated, were the supposed ideal.

Image Courtesy http://www.mikevarneyphysio.co.uk/wp-content/uploads/foot_pronation_supination.png

If you watched the pronator group walk, they might not appear to maintain their arch height very well. But is that always a problem? In the people labeled as pronators there are often joint structure differences that allow more inward collapse of the ankle and foot. In the supinator group there are joint differences that would keep the ankle and foot raised upward. Regardless of foot type, some level of pronation is a normal movement because it allows for shock absorption as the leg is loaded. A certain amount of supination is also normal because it allows for a rigid push off.

We begin our childhood with a lower inner arch height, largely due to a lack of bony structure, and this results in a pliable foot. With normal growth, as the foot bones develop, the inner arch tends to rise and the bones of the leg also change their orientation a bit. In some people the arch really doesn’t increase its height much with growth. And even if it does, in adulthood there can be contributing changes that would affect foot and ankle position:

  • degenerative or use dependent joint changes at front of the foot, the middle of the foot, or the rear of the foot  

  • lower leg muscle shortening

  • weak, inhibited, or injured lower leg muscles or tendons (commonly the posterior tibialis)

  • general hypermobility throughout many of the body’s joints

  • tibia and femur bone structure (twisting, length discrepancy)

The concern is that these changes are also able to affect the movement of the knee, the hip and then even the pelvis and back. We all have a certain acceptable range of motion within each of these areas. If the changes in the foot allow the knee or hip to operate just on the edge of their tolerated position of use then, conceivably, you might have an increase in risk for knee or hip injury.

In actuality, foot structure may be more related to the type of injuries acquired than frequency of injury.

  • According to a 2001 research article in Clinical Biomechanics, higher arched runners developed injuries most often on the lateral side of the leg and had more ankle and bony injuries. Their lower arched counterparts had more knee and medial lower leg injuries.

  • A 2005 research article in the Journal of the American Podiatric Medical Association indicated that triathletes with a more rigid, high arch were at a higher risk of injury compared to neutral and pronated foot types.

  • More recently, in 2014, a meta-analysis in the Journal of Ankle and Foot Research indicated a very slight increase in risk of overall injury rate with the more pronated foot type being related to increased risk of kneecap pain and medial tibial stress syndrome (a.k.a. one of the types of shin splints.)

As you can see, the research is conflicting. The rate of injury is similar between athletes with all foot types. Perhaps we would have different results if we broke the common groups (pronator, neutral, supinator) down into subgroups based upon strike patterns (heel, midfoot, forefoot) to account for variations in demand.

My concern is that many of these studies assess the foot arch height while standing still. Unfortunately, this does not mimic how you use the foot in activity. Someone with a pronated foot structure while standing may not even touch their heel to the ground with running. Is it really going to be effective to put them in a motion control or stability shoe designed with a heel striker in mind?

A 2009 study by J. Dicharry demonstrated that while running the total motion of the navicular bone in the arch isn’t drastically different regardless of foot type. They called the pronators the hypermobile group in this case. Even if the arch of a pronated foot is at a lower position in standing, it’s total amount of motion is only slightly increased from a neutral or supinated foot while running. Neutral and supinated feet were 0.3 mm different between walking and running. Pronated feet were 1.2 mm different from walk to run. 

Should you be concerned with such minor differences and trying to use external devices like shoes to accommodate for them? The first step is to determine whether the pronation that is occurring is structural or a compensation. If forced to compensate, as in the case of decreased calf muscle length, you may need to focus on increasing mobility where it has been lost, like at the ankle joint, by elongating the calf muscles. Forcing mobility where it has already reached an excessive level in the midfoot by neglecting the calf length is not going to be helpful.

Our bodies are very good at adapting to gradually applied stresses, so a person with a more flexible, lower arch should be able to safely progress their activity just like anyone else. The research would suggest addressing the tissues that are the most likely to be injured with each foot type.

For instance, someone with a higher arch could focus on single leg balance and strengthening of the outer lower leg muscles. Those with a lower arch could focus on increasing strength of the inner lower leg muscles. I suggest we should focus on keeping both sides of the lower leg as strong as possible without one side becoming more dominant.

An often overlooked factor is inner foot muscle strength. Several of those muscles are meant to stabilize the arches of the foot, so it would be no surprise to me that decreased inner arch height can be associated with decreased muscle strength. But it’s not always a 1:1 relationship. Little research exists on this because it’s difficult to measure intrinsic foot muscle strength. Look for my blog article on intrinsic foot muscle strengthening soon.

Final thoughts:

  • Progress running intensity and duration in a safe manner using the 10% rule.

  • Keep the calf muscles loose to prevent ankle motion loss with a combination of rolling, massage, dry needling, and maybe stretching.

  • Strengthen the muscles that take the ankle and foot in all directions.

  • Strengthen the intrinsic foot muscles.

  • A pronated foot type does not necessarily require a bulky, stiff shoe and orthotics.

  • A pronated foot type is not going to be an immediate cause of injury, there are other factors to consider.

  • Don’t spend too much time worrying about your foot type because anatomical variation is normal.

  • Let your feet work how they were intended.

Training errors in the athlete, part 6

Too much, too soon, particularly after an injury. Most athletes understand that progressing too quickly in their regular training can cause injury. What they don’t often understand is how to return to sport after an injury. This is the easiest time to go too hard or too long. You can have the “I’m all better” concept down too well.

Injured or not, the body is only capable of adapting at a certain rate. Some tissues can adapt in a few days (cardiovascular system, nervous system pathways), some in a few weeks (muscles), and others in a couple months (tendon, bone). Depending on the location of the injury you must consider what are known as “tissue healing constraints.” For example, a tendon overuse injury can take 1-3 months to resolve with correct progression. A low-grade muscle strain could take 1-4 weeks.

If a runner has tendon pain from a new tendinitis that has been present for 3-4 weeks then I would expect it is going to take weeks, not days, before returning to their pre-injury mileage. It doesn’t always mean you can’t run at all during recovery. It must be a controlled progression. And there is always some type of cross training you can do.

The first day back to running should not be a 5 or 7 mile long run, regardless of terrain or intensity. And that’s what I see many people try to do when they return from injury. They want to get right back up that mountain quicker than they came down it. Stay in the valley for a couple days. For every week away from running I would expect a need for at least a 30% drop in average weekly mileage upon return.

It’s going to take at least a week of no exercise before you actually have a loss of fitness. The fitness losses from 2 weeks of inactivity are similar to those of 4 weeks. And I’m sure you have been cross training to minimize those losses. Point being, don’t rush back into it simply to regain fitness that doesn’t really need to be regained.

Not listening to your body’s warning signs of insufficient recovery. This is similar to what I mentioned last week about not respecting a specific injury early. But you also need to consider a whole body factor. Something is up when your muscles have been feeling constantly tired before, during, and after workouts. You might wake up more groggy than usual or old injuries start to reappear. You need to consider what your body is trying to tell you.

It’s normal to feel a little stiff and achy in your muscles when you start to push them. But when a slow, easy warm-up doesn’t put some pep back in your step after 20-30 minutes then there’s a good chance you could be digging yourself into a hole. If you feel good at that point, then a hard workout is reasonable. If you still feel slower than normal and better yet, are actually slower than your normal, then it’s not a day to push your effort.

For the uninjured, refrain from making any judgments about how your workout is going to proceed until your system is well warmed-up, at least 15 minutes into exercise.

Not performing regular soft tissue maintenance like foam rolling, massage, and compression in recovery, especially after the hardest and longest efforts. Repetitive wear and tear beats up your muscles. Unhealthy muscle tissue equals decreased performance and even pain. As athletes, we surely can’t expect that pushing into exercise-related discomfort multiple days per week generates only 100% positive adaptations in the muscles and other tissues. There are gradual negative adaptations too, like trigger points, adhesions, and loss of muscle tissue length.

Show those muscles a little love with self-massage. Help your lymphatic system function at its best by preventing fluids from accumulating in the spaces around your muscles and other tissues with compression. Options for compression include compression socks or for a more massage-like treatment, a pneumatic compression system, like the Normatec. Most athletes find that massage and compression simply feel good after prolonged exercise.

Running technique: 3 reasons why runners develop shin splints and 7 ways to fix them

I really dislike the term "shin splints." Probably more than you dislike actually having pain from shin splints. That's because the term has been used to describe about five different problems that occur in the lower leg. It's terribly vague.

The term "shin splints" has been applied to injuries that are more specifically described as medial tibial stress syndrome, tibial stress fractures, and exertional muscle pain. Exertional muscle pain is the most common type of problem, so for the sake of this article, I will refer to the shin muscle and tendon pain from exertion as “shin splints."

One of the shin muscles is the anterior tibialis, which is the biggest muscle on the front of your shin region. It’s main function is to pull the front of your foot upward. That's called dorsiflexion (see photo). It's helped by the neighboring extensor hallucis longus (EHL) and extensor digitorum longus (EDL) muscles.

While walking and running, they keep you from catching your foot and toes on rugs, roots, stones, steps, and generally rough surfaces. We’ve all caught a toe, tripped, fallen and groaned in pain as we lie on the ground. These are the muscles you can thank for keeping you from biting it everyday.

There are several reasons why runners will develop exertional shin splints. Some of them include:

Heavy reliance on heel striking. This is the most likely reason a runner, especially a new runner, would develop shin muscle overuse pain. With a heel strike, you must increase use of the anterior tibialis muscle or your foot will slap down to the ground. Runners who heel strike demonstrate a greater dorsiflexion (pointed up) angle upon ground contact compared to a runner who lands with their entire foot flatter or on their forefoot.

In the picture below the ankle is pulling up into dorsiflexion 15 degrees above a neutral ankle position. This is in contrast to the midfoot strike images below where the foot is contacting the ground in a slightly plantarflexed (pointed down) angle. In order to lower the front of the foot to the ground from a heel striking position, the anterior tibialis muscle needs to work extra hard. All of that extra work results in a chronic state of overuse in the shin muscles and tendons, which is easy to imagine when you are asking them to perform 700 contractions per mile. 

Initial contact with heel strike pattern

Overstriding in the forward direction. Along with the heavy heel striking pattern, reaching the leg too far forward with each step will increase the stress on the shin muscles. You can use a heel strike pattern without causing shin splint pain if your foot contacts close to your center of mass. Imagine your center of mass being a line drawn straight down from the center of your hips, as in the following picture. If the foot contacts the ground 12 inches in front of the line instead of 10 inches, the demands are much different on the muscles, tendons and joints.

Most runners who shorten their stride in the forward direction start to land on their midfoot instead of their heel. Compared to the heel strike picture above, using a midfoot or forefoot strike pattern (and sometimes a slightly quicker turnover) causes the stride to be slightly shorter in the forward direction. That's evident with the lower hip flexion degree value. But it's most noticeable that the distance line to the point of contact at the bottom of the picture is clearly shorter than in the previous heel striking picture. It is possible to make an initial contact at this same closer point and use any of the three types of contact patterns. 

Initial contact with midfoot strike pattern

Short/tight calf muscles. If the muscles on the back of your lower leg are so short that you can’t take your ankle into the normal level of upward dorsiflexion motion, the shin muscles are going to need to work harder to overcome that passive resistance. One quick way to assess whether the muscles on the back of the lower leg are too short is to do a full squat. Barring any unusual knee or ankle joint and bone issues, if the feet can't stay flat on the floor, especially without turning the feet out or the arches collapsing, you may have a limitation in the length of those muscles.

Tips for correcting these issues.

1. In the cases of both heel striking and overstriding, the solution is much the same. The foot needs to land closer to your center of mass. You could simply think about taking shorter steps. You can think about it landing directly beneath you (which will never actually happen). A one-inch change in the initial contact point is going to feel like a 12-inch change but I assure you that the awkward feeling is normal at first.

2. Some runners need an external focus to prevent overstriding forward, so matching their cadence to the beat of a metronome can be helpful. Count the number of steps you take with one leg in one minute of running. Those who overstride are often taking less than 82 steps each minute. The metronome can be set for a value greater than 82 while you try to match the step rate with one leg.

3. For tight calf muscles, everyone’s first thought is “stretch.” Stretching is fine if you hold the stretch for at least 1 minute but 2-3 minutes is more effective to mechanically lengthen these tissues. And you would have to do it daily for at least a month to get much change. It can be more effective to perform soft tissue work with a foam roller, massage stick, tennis or lacrosse ball, massage therapist, or manual therapy from a Physical Therapist. Regardless, just try something! Lessons on muscle rolling here.

4. Relax the anterior tibialis muscle with consistent soft tissue maintenance. Trigger point dry needling or myofascial release can work wonders to make the muscle happy and decrease pain quickly. The massage stick can be great too. Lessons on muscle rolling here.

5. Practice engaging the anterior tibialis muscle by walking on your heels for 30-60 seconds continuously each day. Preferably after your symptoms have calmed down a bit.

6. Progressively increase your mileage. Going for a 4 mile run after a month of no running is a huge training error. Sometimes those muscles just need to be conditioned correctly. 

7. Try a different shoe with a lower heel height. Pair this with the other solutions. A thicker heel can mean greater shin muscle load. And that thick heel is often the reason people heel strike hard in the first place. 

If you battle repeatedly with shin splints, consider having a thorough running technique and gait evaluation. Yes, I can get the pain to go away easily with a couple treatments but don’t you want to keep it away permanently? A couple of small changes can mean a huge difference in your pain onset.

Training errors in the athlete, part 5

Training with other people all the time. Do you thrive on attention and praise in order to push through a workout? Sometimes you just need to go it alone to build the mental fortitude required to perform at a higher level. I mean Rocky Balboa trained alone most of the time and he seemed pretty talented so that has to be a sign it will work for you too. Gonna fly now...

I don't see anyone else around, do you?

Moving on to the other end of the spectrum, there’s the chance that other athletes can push you too hard, too often. Peer pressure kicks in and although your instinct says “that’s enough,” you go beyond your safe limitations and become injured. Save it for the competition. That’s where it is nice to have a coach to tell you when to shut it down.

Skipping the warm-up. Warm your muscles up slowly and they will perform better. A gradual warm-up can improve performance. Research indicates muscle fiber exposure to lactic acid just before intense exercise allows the fibers to tolerate even more lactic acid production. The physiology of the muscle fiber can function better at a higher temperature too (up to a point of course).

According to a 2012 literature review in BioMed Central Medicine, a proper warm-up containing “stretching, strengthening, balance exercises, sports-specific agility drills and landing techniques” can be effective for preventing injury. This is unfortunately more involved than many athletes envision when thinking about a warm-up routine and they shy away from it as a result. 

At the least, warming-up should be a whole body routine that emphasizes full joint mobility, a gradual increase in heart rate, directional changes, and most importantly, rock music. The warm-up period, especially just before a competition, can be a powerful psychological motivator.

Ignoring joint mobility and flexibility. Some people have really poor mobility. I don’t mean, can you bend over and touch your toes? I mean will your hip flex to a full 120 degrees to allow you to squat all the way down at Crossfit? Do your ankles have the full range of motion necessary to prevent your arch from collapsing while running? Limits in mobility set by a single joint or muscle can impact movement further away than you might realize (ie. ankle movement can change hip movement).

The type of exercise you expect to participate in should dictate what motions you need to improve. If there are specific known limitations, they should be addressed in order to decrease stress on adjacent tissues and regions. Mobility limitation is the reason that the Crossfit “Mobility WOD” exercises exist. The point is that you have to take care of your body with a little routine supplemental work in order to enjoy your regular sport safely and improve performance. 

To Foam Roll the IT Band or Not to Foam Roll the IT Band?

There are about 50,000 articles on rolling or not rolling the IT band, or iliotibial band, on the internet right now. So now there’s 50,001 with my addition. There’s every topic from “you’ll never get the ITB to stretch out” to “don’t roll it because the problem is actually at your hip” to “keep rolling the ITB.”

I agree, the ITB is so thick and strong you are wasting your time to try to specifically stretch it or roll it out. According to an older article (1931) from the Journal of Bone and Joint Surgery by C.M. Gratz, MD:

“The specific gravity of fascia lata is about 1.31 and the average ultimate tensile strength is approximately 7,000 pounds per square inch. Soft steel has a specific gravity of 7.83 and an ultimate strength of about 45,000 pounds per square inch. Thus fascia lata is nearly as strong as soft steel, weight for weight.”

The IT band needs to be a strong material. The IT band functions are to stabilize your knee and produce hip movement by working along with the tensor fascia latae and gluteus maximus muscles (refer to the image below). And yes, lateral knee overuse injuries, including IT band region problems, tend to be related to weakness or abnormal activity at the hip and trunk muscles. Maybe something is wrong down at the ankle and foot too.

You shouldn’t be relying on the rolling, or any soft tissue technique for that matter, to make up for lost strength or bad exercise mechanics. Those body mechanics need addressed and your strength needs to improve. It wouldn’t surprise me that a lateral knee pain sufferer would also have weak gluteus medius and gluteus maximus muscles. Most people could use stronger glutes. And maybe you shouldn't have suddenly done a 2 hour long workout when your longest had been 1 hour. 

What the anti-rolling crowd is forgetting is the fact that the IT band is covering a pretty big portion of quadriceps muscle. Because it’s generally a positive to routinely roll or massage the rest of the quadriceps, why would you suddenly neglect such a big part of it? I wouldn’t, personally.

And what if that lateral knee pain is actually coming from trigger points in the quadriceps? At least the rolling was helping to keep the quadriceps relaxed and generally making the nervous system happier.

If you bought into the “no ITB rolling” philosophy, think it over again. At the very least, use a tennis or lacrosse ball to roll the thigh directly in front of the IT band and directly behind it. Take care of your quadriceps and hamstrings muscles. Use the ball, massage stick, or foam roller on the tensor fascia latae muscle too, up at the front/side of each hip.

Strengthen your hips and keep on rolling.

Training errors in the athlete, part 4

Underestimating the importance of proper recovery. When it’s time to work hard in a workout or competition you need to have some gas in the tank. That tank doesn’t get filled up without good recovery techniques like full days off, active recovery days, consistent sleep, compression, nutrition quality and timing, proper hydration and muscle maintenance.

If you start every competition or workout on a half tank, guess what happens? You go half as far with half the intensity. Sometimes that's intentional and planned. But many times it's not. Then as injury and overtraining occur, you have to ask yourself, “What am I really getting out of this?” In order to feel your best, remain healthy, and perform at your best, recovery is a huge part of the equation. Don't dig yourself into a hole that you can't get out of. 

Not working hard enough to produce a strong stimulus that the body wants to adapt to. Athletes are supposed to be constantly pushing their bodies on many of their training days. That’s how you become better, right? Unfortunately it’s also how you become overtrained, injured, stale, and burned out.

This leads you to constant training at a moderate effort on “dead” muscles. Or running the same distance every day. Monotony is the straw that broke the camel’s back. For runners, yes, you need days to emphasize aerobic conditioning in easy efforts ranging from 30 minutes to 3 hours. Other days you can have interval training that emphasizes anaerobic work at a really high effort for anywhere from 30 seconds to 5 minutes. Sure there’s a place for a moderately paced tempo run of 15 to 60 minutes, but not every day.

Strength training athletes need to avoid constantly using a weight that causes failure at 10, 12 or 15 repetitions. Or always doing just one set. If you are really after a change in performance, there needs to be a training cycle where the weight is significant enough to cause failure at other points, like 8, 5, or even 3 repetitions. And other times it’s fine to do 20 repetition sets. The point is, change the stimulus.

Indoor general fitness athletes are often one of the most guilty of this mentality. Three and four times per week they bounce from one cardio machine to another, being sure to start breathing harder and break a sweat at each machine for 10 or 20 minutes. They occasionally check their heart rate and compare it to the machine’s chart. No surprise to see a heart rate of 70% of the predicted maximum. And they wonder why they never see significant fitness changes.

Then there are the athletes that push a little harder but it’s just to that 85% level, which definitely hurts more. But then they struggle to sustain it as one steady effort for longer than 10 minutes (because it hurts) at which point the effort drops a notch. Meanwhile, other people in the gym are barely working at all.

In any sport, the key is variety. Variety in intensity, duration, training surface, speed, force produced, and direction of movement. Yes, you want adaptation to a consistent stimulus for a while but then you have to change that stimulus to continue making gains. 

Ignoring injuries when you first begin to have symptoms. Some injuries classically only hurt at certain times in their formation. That doesn’t mean they aren’t a problem. It doesn’t have to hurt all of the time to be a problem. Don't ignore it. Never ignore it. Yes, you can try to treat it yourself for a little while. That really might work.

But please make your life and my life easier by just coming to Physical Therapy within a couple weeks of the problem onset, even if it’s just for a consultation. If you don’t like what I have to say about it then seek another opinion. Regardless, if you intervene early, and start the right treatments, your recovery time is going to be drastically different.

For instance, if I see someone with back pain from a sacroiliac joint sprain in the same week they are injured, then they often recover in well under a week. If the sacroiliac joint has been a problem for 2 months and had no proper treatment, then buckle up for at least a month of consistent work. #getPT1st
