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. 

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

Training errors in the athlete, part 1

Which of these are you guilty of performing?

Specializing in a sport and being entirely unwilling to deviate: Variety is critical for injury prevention, mental outlook, and general health. Unless you are a triathlete, pentathlete, or decathlete, you might find yourself unwilling to stray from the single sport you know. First off, you should strength train. Strength training is no longer an option; it is a requirement. Crosstrain before you get hurt (and you might not get hurt in the first place). Try something that is non-competitive and don’t turn it into a competition. (Yes, that’s probably hard.) Take a yoga class. Play pickup basketball with a couple friends or just shoot around. Try swimming. Just do something that is very different than your normal and do it often. This is especially true for young athletes who aren’t finished maturing. Research suggests that athletes who didn’t specialize at a young age can perform better as long as they were performing some form of athletics. The key for all of us is simply being an athlete.

Assuming your skills and technique don’t need further work: Skill work is primarily about training your nervous system to use a specific pattern. A good overall athlete has more options for movement patterns. Some patterns are highly ingrained and some are not. You want instinctive patterns to be close to an ideal. That way, when fatigue occurs you still demonstrate precision and efficiency. Every athlete could improve their performance with at least weekly emphasis on movement drills, strengthening specific motions, increasing muscle power output, and basically fine-tuning they way the nervous system creates each sports-specific motion. Regardless of sport, there’s room for greater efficiency and adding skills to your repertoire. Even running, which some people assume is innate, is a skill that should be broken into components for drill work. 

Training alone all the time: Sure, you are probably mentally tougher than the average bear, but this problem allows you to slack off occasionally when there’s no one there to push you. Which means you drop into the dreaded moderate efforts that lead to “dead” muscles, overtraining, and slower than optimal nervous system patterns. My motto is “there’s always someone faster and stronger.” Go train with that person at least once a week. A coach could assume part of the role of a training partner, so I’ll give that half an exception.

Footwork Friday - Why am I developing black toenails?

Many runners develop black toenails, especially after longer runs. This is a very specific type of bruising known as a "subungual hematoma." It has often been believed that this is caused by the shoe's toe box size restricting the toes to so much that direct trauma and bruising develops. This isn't always the case, and The Gait Guys suggest that there is another cause in one of their older blog posts.

Many runners tend to curl their toes downward in an effort to grip the inner surface of their shoe. In addition to black toenails, another sign of this habit is the presence of a callus on the very tip of the toe. Curling your toes downward requires heavy use of the flexor digitorum longus and/or flexor hallucis longus muscles. Using these muscles is a way to gain stability within the shoe, but it is not a good habit. Regardless of the presence of black toenails, this should be avoided because these muscles are not built to produce larger amounts of power or engage in constant stability control.

The area under a toenail has a large blood vessel supply close to the nail bed, so bruising occurs more easily with any vessel damage. Gripping downward combined with a small forward/backward movement of the shoe causes a shearing force through the skin and fatty tissue of the toes. That repetitive pressure with this shearing force against the insole is thought to be enough trauma to disrupt the blood vessels. The solution? Don't grip the shoe with your toes.

Shorter runs usually aren't enough repetition to harm the vessels, but longer runs will. Especially as we fatigue we  rely more heavily on muscles that aren't fatigued as much during shorter runs. Trail running could cause a greater problem because the trail surfaces are unstable and the runner will more frequently seek stability by gripping with the toes. Also, there is a greater likelihood of steeper inclines and declines that will cause more sheer force of the foot against the insole.

Although there isn't existing research to back up this idea yet, it makes good sense. Next time you are running, think about what your toes are doing. If you are gripping the inside of your shoe then STOP IT!

Balance and proprioception: overlooked training for runners and athletes with knee pain and other leg overuse injuries

After reading the title you’re probably wondering a few different things:

  1. “What does balance have to do with being a good athlete?”
  2. “What the heck is proprioception?”
  3. “What’s for lunch today?”

These issues come up time and time again when I work with injured athletes from many different sports. I’ll address the first two questions and you are on your own for that last one.

Let’s review some anatomy first. There are specialized nerves in your joints, ligaments, muscles and tendons that help sense position and movement of your body. That sense is referred to as proprioception. Without these and other specialized nervous system parts you couldn’t close your eyes and know how your body is positioned at any instant. And you couldn’t stand up or walk in a stable manner. Clearly you don’t absolutely need vision to know where your body is or you would be watching your feet while you walk or run, right? By sensing position, these special nerves are also part of what keeps us stable so we aren’t just stumbling around like a drunk college student on Friday night. But many of us, even some of the best athletes, have poor proprioceptive awareness. For so many of us these proprioceptive pathways aren’t challenged often, and then the “use it or lose it” principle kicks in. Especially as we age, we begin to lose the efficiency of these specialized nerves. As these nerves degrade we can’t precisely place each leg with athletic movement. This decreased precision leads to poorer biomechanics that can be related to overuse injuries. Also, a previous or current sprain at the knee or ankle ligaments will negatively impact your positional awareness and movement precision because of the damage that a sprain will do to these special nerve endings. All in all, aging, previous injury and a lack of training stimuli are going to degrade the quality of your movement precision.

Do you think you have good balance and stability? Let’s find out in a couple simple steps. Try these in your bare feet.

  1. Stand on one leg as long as you can without touching anything and count slowly. How many seconds can you last on each one? Less than 30 seconds? In that case you’ve got a lot of hard work to do. More than 30 seconds? Well that’s a good start but we’re only getting started.
  2. Now stand on one leg as long as you can with your eyes closed. I bet most of you aren’t going to brag about this one. If you don’t make it to 30 seconds on one leg with your eyes closed then there’s likely to be some room for improvement in this aspect of your training.
  3. If you have some kind of superhero balance, try standing on one leg, keeping the eyes closed and tilt your head backward or turn your head to each side. This is really hard and will likely stop all but the best balancers.

So what are you doing to train this aspect of your abilities? I imagine several folks are going to say “nothing” because they didn’t know it was important. For what is essentially very little effort, I’d suggest working on your balance, stability, and proprioception to improve your running and prevent injury. Here are a couple ideas to address this area:

  1. Stand on one leg with your eyes closed. Sound familiar? If you are able to stand steadily on one leg with your eyes closed on a flat floor then stand on an unstable surface like a folded towel or pillow with your  eyes closed. Or, you could try moving your head as mentioned earlier. Aim for 30 seconds of the most difficult, but achievable, level. Switch sides.
  2. Single leg Russian dead lift. One of my favorite exercises. In a standing position pivot your trunk forward from the hip of the weight-bearing leg. The other leg raises up behind you for every same degree the trunk goes downward. Don’t round your back. Repeat 8-15 times until the hamstrings and buttock muscles tire. Switch sides. You can do this with and without weight. 
  3. Single leg step down. Stand on a single leg on the edge of a step. Drop down very slightly by bending the weight-bearing leg, keeping your weight back on your heel. Return to the start position. Don’t let your bending knee travel too far forward beyond the front of your foot. Think about keeping your buttock back. Repeat 8-15 times, at least until your hip muscles and quadriceps are getting tired. Switch sides. You can also do this with and without weight. 

Let me know how you do with these activities at mountainridgept@gmail.com. Easy? Hard? These skills become particularly important for runners and other athletes with overuse related knee pain, ankle pain and foot pain.

Footwork Friday - Runner's bump

I thought I would throw this one out there since it's recently affected my running on a small level. A couple weeks ago I noticed I was developing a small bump at the base of my anterior tibialis tendon after a long run. Getting old is such a great thing isn't it?! It hasn't really been painful but the bump will snap up and down if I have my shoes laced tightly. It's a synovial sheath irritation in the slick layer that allows the tendon to glide smoothly. 

Runner's Bump

Ultimately, excess lacing tightness is what caused the bump to form. I have a habit of really cinching down on my shoe laces and this caused some increased stress on this area. Now, if I was to over-tighten the laces, it would cause the little bump to snap up and down under the laces and eventually swell even larger. So that's clearly not ideal. The repetitive snapping is annoying and might become painful with enough exposure. I'm not waiting to find out. Another factor that could contribute is frequent uphill running because it would cause you to increase the use of the anterior tibialis muscle and tendon, close the ankle joint up further and increase the friction across the front of the tendon against the shoe. My right foot collapses inward slightly more so the tendon may experience slightly more stress from that as well. 

As a result I've done a slight modification to my lacing pattern to relieve the area of its pressure. By changing the lacing pattern the bumped area reduced significantly in swelling and overall size. Applying ice is another good measure to help decrease localized swelling and pain. 

These types of bumps will also sometimes occur at the Achilles tendon from the heel cup of the shoe rubbing the tendon repetitively. In any case you could modify the shoe by cutting out a small portion of the heel material that is rubbing or get into another pair of shoes that doesn't stress the area. 

Please let me know if you have any questions about shoe lacing patterns or tendons forming mysterious bumps at mountainridgept@gmail.com. 

Footwork Friday - Basic Lateral Agility Drills

Welcome to Footwork Friday where we introduce agility drills, strengthening, and muscle care techniques for the athlete who understands how important their feet and legs are in carrying them through to the next step in their active lifestyle. 

Runners and many other athletes don't get enough lateral movement in their training. This is why we tend to weaken in side-to-side movements and we also tend to become injured because of instabilities side-to-side. Even in an uninjured state, learning to stabilize the body to prevent lateral movement can be very useful to move quickly and safely across unstable surfaces like rocks, roots, grass and mud. As far as pure performance is concerned, increased lateral movement is an energy waste when you are trying to move quickly forward.

The agility efforts do not need to be long. The technique just needs to be as accurate as possible. Like I've shown in the videos, a 10-15 yard section is plenty long enough. Go through each drill 2-4 times. For any agility drill I recommend fully recovering between efforts because you are ultimately trying to train your nervous system, not your heart or lungs.

Initially, for the first drill, focus on keeping the contact light and not crossing one leg over the other. Strive for keeping the body tall. As you learn what it feels like to "stick" the outer leg, try to make sure your knee is staying straight over top of your foot. In other words, the knee doesn't bow inward or outward. It does need to be bent for a soft landing though. This is commonly done with an agility ladder but I prefer to do them in the middle of a short and easy run or a moderate distance run to keep the right muscles awake. As you get faster you can focus on lowering your body closer to the ground. 

For the second drill focus again on light and quick contact with the ground. Emphasize keeping your stance wide and pumping the arms directly forward and backward. I like to do this in the middle of my runs as well. Just be careful because it will skyrocket your heart rate and effort levels very quickly.

Have fun and let me know if you have any questions at mountainridgept@gmail.com
