Getting Slower With Age? Sarcopenia is Preventable and Reversible!

So why is it so hard to keep muscle mass when we age? Turns out it is caused by sarcopenia. Really! I'm not making up the term. Sarcopenia is the progressive loss of muscle mass that results from the normal aging process. It has been felt, in the past, that the loss of one to two percent of your muscle mass each year after the age of 40 is inevitable.

Turns out there are lots of things we can do about sarcopenia. One of them is to stop trying to look like a cachectic Holocaust victim and actually build some upper body muscles!! Runners tend to feel like if they bulk up at all in their upper body that it will slow them down. Research actually has refuted this claim over and over, but it is still one of those long-standing running myths. Strength training actually helps preserve muscles and strengthen bones which often improves your running economy and hence makes you more efficient, reducing the amount of energy to run at a certain pace. Win-Win!

Many factors go into the onset of sarcopenia. Chronic disease and environmental factors can accelerate loss of muscle mass, but these are not really controllable. Factors under our control that affect the progression of sarcopenia are motor unit restructuring, protein deficiency, and changes in hormone concentrations. These combine to produce the age related loss of muscle coordination and mass.

Really, it is all about proteins. There are two kinds of proteins; non-essential (those your body can synthesize) and essential proteins (proteins we need to get from foods). Your body seeks a balance between protein production (synthesis) and usage (metabolism) for energy and cell structure. We don't usually lose our ability to metabolize proteins with age, but we do lose our ability to synthesize them. This is where hormone balance comes into play. Things like Insulin-like growth hormone (IGF-1), testosterone and growth hormone. As our bodies age, our hormone concentrations decline. This is why aging baseball players love growth hormone, they think it stops sarcopenia! (Hgh declines after age 40 but there is not good research that proves supplementation will actually help!) What's more, it appears that as we age, we actually require more protein but continue with a similar diet hence we are out of balance.

The hormone decline and protein deficiency one-two punch is largely responsible for sarcopenia, but when you add the most vital aspect - motor unit restructuring - they combine to form a cocktail that results in the physical manifestation of aging. Motor unit restructuring is the product of the inevitable death of neuron cells. Fast twitch neurons (those responsible for precise or quick movements) die off first. When the cell reaches its predetermined life span, it dies. When a motor neuron dies, the muscle fibers that are under its command can deteriorate or atrophy. To prevent atrophy, when a fast twitch neuron dies, a slow twitch neuron nearby attaches itself to the now abandoned muscle fibers, innervating and keeping them alive. This change is known as motor unit restructuring. This is why we become slower and less coordinated as we age.

So how can we thwart this process? Move! Often! Sitting on the couch and leading a sedentary lifestyle is a good way to ensure sarcopenia with age. The best way to cure or at lest slow down the onset of muscle mass loss is resistance training. We recommend our patients participate in daily exercise, but often this is not enough. It will help your cardiovascular system, but resistance training with weights is the only way to reverse muscle mass loss. Couple this with increases protein intake to have the building blocks to redevelop muscles.

So, you want to be able to beat the young pups when you are in your 50's and 60's? Talk to your doctor about any health issues like diabetes or hypertension. Change your diet to higher protein and less carbohydrates. Forgo the pasta dinners and add lean protein! Resistance training with light weights and high repetitions at least 45 minutes, three times a week. Make it a habit you will take into your senior years!

You will thank me when you are still running in your 70's!

Can I Run on a Stress Fracture?

Lots of good questions in my Grapevine, Texas office and on the website this week. It is definitely marathon time of year! Lots of aching feet and legs from erratic training and “too much, too soon, too fast syndrome”.My favorite is “I have XYZ Marathon in a few weeks, Can I run on a stress fracture?” This was actually asked three times in two days by a patient and once in an inquiring email on www.myrundoc.com

Of course, my answer was, “Really?.....” Ok, so you think you are a tough guy and can run through a stress fracture, but this is a very bad idea!

1. Hurts like hell!



2. Probably break it into many more pieces



3. Probably end up not running for months



4. May end up on my operating room table for pins, plates and/or screws!



5. Are you really that stupid???

Seriously? A stress fracture is a small crack in the bone that hasn’t fractured all the way through. Guess what happens when you run on it? It breaks all the way through!

So, if you are running in the Olympic marathon and think you are amazingly tough, then try it; but bottom line: NO! You can’t run on a stress fracture! If you try, you probably won’t be running for quite some time after that race, so it better be worth it!

Learning point: If you even think you may have a stress fracture, an x-ray is indicated pronto! Remember that they often do not show up on plain films for up to two weeks after the injury. The tip of my index finger is usually right! Give us a call and we can squeeze you in. The best part of having 5 doctors at Foot & Ankle Associates of North Texas in Grapevine, is that we can always find an emergency spot with one of our doctors!

11 Reasons Why Pool Running Doesn't Suck!

As a sports medicine podiatrist, I often encourage injured athletes to cross train and keep up their cardio fitness during their “rest period”. Pool running can be very helpful, but is frowned on as extremely boring and down right tedious by most runners and triathletes alike.

I also had to enter the conversation in our series “The Journey to Texas Ironman” with a shout out to everyone who has a little ache or pain in their foot or ,God forbid, a stress fracture, but still wants to join us at the starting line of the Texas Ironman in May. This was taken and liberally adapted from an article in the December 2010 issue of Triathlete magazine:

11 Reasons Pool Running Doesn't Suck
Completely stolen and altered from Holly Bennett, please forgive me….

1. It gives the barefoot movement a whole new angle -- and spares the wear and tear on your running kicks. Better than a pair of Vibrams!
2. You earn sympathetic looks from the cute boy-toy lifeguards. And at 40+, let’s face it – we like to look and dream, but would have a heart attack if they were serious!
3. Until now you thought breastroke was the slowest way you could possibly travel from one end of the pool to the other. Or my pathetic looking side stroke!
4. Hello, six-pack! Water running recruits those pesky, oft-neglected core muscles. Even your arms will exhibit extra buffness, strengthening with the resistance of the water. Let’s face it; most of us girls would be happy with a two pack after 4 pregnancies’!
5. If ever you long for a surrogate granny, there are plenty of gentle, smiling faces in the therapeutic lap lane. And most of them are my patients!
6. From your vertical vantage point, you can observe, admire and critique the swim strokes of the nearby lap swimmers. Maybe you'll learn something. And often times, you will realize your stroke is not so bad!
7. There are no rocks, stumps, curbs or other obstacles in the pool. In the water, you're no longer a danger to yourself. You can try running with your eyes closed. (Note: Resist the urge to fall asleep.)
8. One rarely encounters rattlesnakes while pool running. Or any kind of creature commonly seen while we practice open-water swimming on Lake Grapevine. And it’s not 60 degrees!
9. If you hop in immediately following a bike session, you get to call it a "P-run."
10. If you can mentally endure two hours of water running, your next Ironman marathon will feel short. I highly encourage a swim man IPod…..I could never even train for the Ironman swim without it.
11. And of course, the most important reason pool running doesn’t suck: Dr Crane won’t completely bust you when she or Janet passes you on the trail when you are still supposed to be in the walking cast!

Bottom line, pool running really doesn’t suck if you have the right attitude and tunes! Embrace the change and come out of the “rest period” that much stronger so none of us will be carried off by the ambulance come May!

Chronic Heel Pain Responds to Night Splint

Plantar Fasciitis a.k.a. Plantar Fasciosis (PF) is an extremely common foot injury usually described as heel pain. The pain is usually first thing in the morning and after rest. PF is by far the most common injury I see in my North Texas sports medicine clinic. PF is seen in most athletes, and is one of the most common running injuries. One study described PF as affecting 8% of habitual runners. 8%! When you calculate that approximately 2% of the US population runs on a regular basis (based on a survey of how many people ran a marathon in their lifetime). That is a lot of people. Actually the rough estimate is 6.2 million runners in the US alone with about a half a million suffering from heel pain. Wow! Oh my aching heel!

Why is there so much heel pain in runners? Too much, too soon, too fast syndrome. In other words, we want to be in shape way before our bodies are ready. The rule of adaptation states that our bodies become stronger with small incremental increases inn stress, but we break down with large incremental increases in stress. This is why PF is described as an overuse injury.

So how do we treat is? A protocol approach that starts with simple, stupid and follows a stepwise pattern that ends with 85% of runners having complete resolution with conservative therapy and 15% going on to move invasive surgical procedures.

Mainstays of treatment: orthotics, better and/or different shoes (that is an entire article in and of itself), lots and lots of stretching, night splint, anti-inflammatories, physical therapy, extracorporeal pulse activated treatment (EPAT), and in some cases, injection therapy (always a debate in athletes).

Simply reducing pain and inflammation alone is unlikely to result in long term recovery. Rest is usually not enough. The minute the runners gets back to activity, their pain is back! I find that most runners, especially over the age of 40, desperately need to stretch their Achilles tendon and plantar fascia. The plantar fascia tightens up making the origin at the heel more susceptible to stress. The best way to do this is a combination of dynamic stretching throughout the day (see my video on Youtube) and a night splint. A plantar fascial night splint is an excellent product which is worn overnight and gently stretches the calf muscles and plantar fascia preventing it from tightening up overnight.

Why does a night splint work, especially in athletes?

The plantar fascia is the ligament that holds up your arch. It is a thick band of fibers that go from the heel of the foot across the bottom of the foot to the toes. Plantar fasciitis is considered to be an inflammatory process following micro tears in the fascia. Plantar fasciosis is a degenerative process that occurs after several months of chronic plantar fasciitis. The reason PF causes so much pain in the morning, is that during the night the foot is relaxed and drops so the toes are pointed downwards. In this position the plantar fascia is relaxed, healing of the micro tears occurs overnight, but when the foot is put to the floor in the morning the fascia has to stretch to a longer position and this tears the new healing. Think of ripping a scab off every morning! Ouch! The idea of a night splint is that the foot is held overnight with the toes pulled upwards and thus the healing occurs with the fascia in its stretched position.

Many research studies have looked at night splints and the treatment of plantar fasciitis. There have been some mixed results due to the construct of the studies, but overwhelmingly the whole body of evidence suggests that night splints can help ease pain and assist healing, and this is especially true for people who have been suffering from plantar fasciitis for several months or more (truly plantar fasciosis).

Night splints do generally have to be used consistently for at least one month or more before significant improvement is seen. If you are a light sleeper, just make sure your wear it at least 4 hours a night.

A number of good night splints are available, and the fit and comfort is important given you will be wearing it for at least 6 weeks AFTER your symptoms resolve. A dorsal night splint will allow you to walk to the bathroom in the middle of the night without taking it off. A posterior night splint usually is better tolerated long term.

Got an aching heel, seek out a running podiatrist to get you back on the roads in better shape than you left them!

RunDoc at DFW Sports Medicine Symposium

This morning I spoke at the DFW Sports Medicine Symposium in Arlington, TX. What a great crowd! Over 300 physical therapists, athletic trainers and sports medicine physicians from all over Texas gathered to discuss advances in the medicine of sports.

I spoke on running injuries and more specifically the need for a complete biomechanical exam to not only diagnoses, but to guide your treatment plans. This way the runner can return to running in much better shape than they walked into your office. I feel it is a missing link in a lot of offices due to the time involved. Dynamic gait analysis can actually help the clinician diagnose the root cause of an injury instead of just treating the symptoms. This will decrease the chance of a repetitive injury.

I also talked about the current barefoot running phenomenon and the fact that the average runner will most likely not benefit from barefoot running due to poor biomechanics and muscle imbalances. There is much more of a chance that they will actually hurt themselves. Those runners with fairly good biomechanics and patience can benefit from some barefoot running in a controlled environment. Lots and lots of questions still exist and more biomechanics research needs to be done in this arena.

The need for functional foot orthotics was also discussed. No! Every runner does not need orthotics, but almost 80% need some kind of biomechanical help. Most can be accommodated with shoes, stretching and strengthening programs. You would be amazed how much impact a core strengthening program can have on your running biomechanics. Recurrent, nagging injuries often require orthotic control to alleviate recalcitrant pain.

The last thing I discussed was the need for a gradual return to sport so there will be no more of the too much, too soon, too fast phenomenon that plagues so many runners!

A great question and answer session followed. I gave away a few copies of my book, If Your Running Feet Could Talk. I think we all learned something this morning. A good time was had by all and all the athletes in the Dallas-Fort Worth area and all over the State of Texas will benefit!
