Flexibility and Stretching -- Not Helpful?

Here is a surprising piece of research:

The best runners were the least flexible. PubMed

The study is from a group of physiologists at Nebraska Wesleyan University. They found that the tightest muscles were the most efficient, both for men and women.

In fact, the latest science suggests that extremely loose muscles and tendons are generally unnecessary (unless you aspire to join a gymnastics squad), may be undesirable and are, for the most part, unachievable, anyway. “To a large degree, flexibility is genetic,” says Dr. Malachy McHugh, the director of research for the Nicholas Institute of Sports Medicine and Athletic Trauma at Lenox Hill Hospital in New York and an expert on flexibility. You’re born stretchy or not. “Some small portion” of each person’s flexibility “is adaptable,” McHugh adds, “but it takes a long time and a lot of work to get even that small adaptation. It’s a bit depressing, really.” How Necessary Is Stretching?

As someone who has always had tight hamstrings and very poor flexibility, I can agree with that last sentiment: It is a bit depressing. Nearly a decade of daily martial arts training increased my flexibility greatly (considering where I started), but never to the extent I wished. I'm just not a stretchy person, and never will be. And, just as this study suggests, a decline in my daily practice led to a decrease in flexibility -- though I will disagree with their sentiments to extent of saying that I did experience a significant change in flexibility, but it took a lot of work. The payoff for inflexibility seems to be more efficient use of muscles and greater stamina. Certainly, the genetic aspect seems to be borne out by my experience. In general, Asian martial artists tend to be more flexible than their American counterparts and some adaption of techniques and warm-up exercises seems appropriate for different body types. Please note that extreme flexibility, while impressive in some techniques, may make the athlete more vulnerable to injury.

For the casual athlete, the goal has to be avoiding injury.

If, on the other hand, “you can’t get anywhere near your toes, and the lower part of your back is practically pointing backward” as you reach, then you might need to try to increase your hamstring flexibility, Dr. Knudson says, to avoid injuring yourself while running, cycling or otherwise exercising. You can find multiple hamstring stretches on YouTube, although you should consult with a physical therapist before replicating them at home; proper technique is important to avoid injury. “You won’t get a lot of change,” Dr. Knudson says, ” but a little may be all you need.”

But, what about those athletes -- such as gymnasts and ballet dancers -- who really do need more flexibility? Can acupuncture help? In my acupuncture practice, the most effective technique I've found has been shallow needling into the muscle sheaths and micro-current electric stimulation. Simple daily stretching seems to be necessary, but not sufficient for a significant change in flexibility. Both from personal experience and from the experience of my patients, I have found herbal formulas featuring San Qi, to be helpful.

Exercise Makes You Less Anxious

I see this regularly with patients who come in for depression, fatigue, anxiety -- if I can talk them into regular exercise, their symptoms improve. Of course, I'm doing acupuncture and herbs at the same time. But, therapeutic movement really seems to speed the treatment. The flip side of this is that over-training, pushing the body too hard -- especially without adequate nutrition and rest -- can cause anxiety.

This article looks at scientific research to explain why exercise reduces anxiety. In a nutshell, it seems to be that exercise induces the growth of new neurons that are less reactive to the hormonal and neurotransmitter effects of stress. It takes at least three weeks for these changes in the brain to begin to appear.

“Something happened between three and six weeks,” says Benjamin Greenwood, a research associate in the Department of Integrative Physiology at the University of Colorado, who helped conduct the experiments. Dr. Greenwood added that it was “not clear how that translates” into an exercise prescription for humans. We may require more weeks of working out, or maybe less. And no one has yet studied how intense the exercise needs to be. But the lesson, Dr. Greenwood says, is “don’t quit.” Keep running or cycling or swimming. (Animal experiments have focused exclusively on aerobic, endurance-type activities.) You may not feel a magical reduction of stress after your first jog, if you haven’t been exercising. But the molecular biochemical changes will begin, Dr. Greenwood says. And eventually, he says, they become “profound.”

This latter result isn't talked about but Chinese Medicine is very clear on the topic. Moderation in activities along with adequate rest and recovery time is crucial for health benefits.

Moderate Exercise to Boost Immunity

Here's an an article from the New York Times describing research on the effects of exercise on the immune system. The main study involved exposing different groups of mice to the flu virus. One group had no exercise, one group moderate, and one group pushed to exercise intensely. The moderate exercise group did well, and the intense exercise group did very poorly. The results tell us about mice, but we can guess that it works the same way in people -- and certainly, I recommend only moderate exercise for my patients who are simply interested in maintaining health.

When you are an athlete in competitive training, you need to take these effects into account -- especially in focusing on having adequate recovery time and adequate nutrition to support you body's training. And, also, to note that the studies describe the negative effects of 'intense exercise' on immunity. That definition is very flexible and will depend on the person doing the exercise. If you have trained well, your capacity for healthy exercise will be greater.

The key finding in this study:

The bulk of the new research, including the mouse studies mentioned, reinforce a theory that physiologists advanced some years ago, about what they call “a J-shaped curve” involving exercise and immunity. In this model, the risk both of catching a cold or the flu and of having a particularly severe form of the infection “drop if you exercise moderately,” says Mary P. Miles, PhD, an associate professor of exercise sciences at Montana State University and the author of an editorial about exercise and immunity published in the most recent edition of the journal Exercise and Sport Sciences Review. But the risk both of catching an illness and of becoming especially sick when you do “jump right back up” if you exercise intensely or for a prolonged period of time, surpassing the risks among the sedentary. (Although definitions of intense exercise vary among researchers, most define it as a workout or race of an hour or more during which your heart rate and respiration soar and you feel as if you are working hard.)

Chinese medicine has a number of herbs that help with stamina and immunity -- like Ginseng and Reishi Mushroom. Supporting the immune system before and especially after competitive events is a great idea.

Best Exercise for Healthy Bones

Bone density and bone loss becomes a concern for the majority of Americans who live past the age of 50 -- that's currently about 44 million people who experience mobility problems and increased mortality. Even in less severe cases there is definitely a reduction in quality of life and the kind of exercise you can do. If you are or plan to live past 65, osteoporosis and hip fractures are a serious problem (JAMA Report). The NY Times just did an article summarizing recent studies:

Although the number of hip fractures has declined in recent decades, the study found that the 12-month mortality rate associated with the injury still hovers at more than 20 percent, meaning that, in the year after fracturing a hip, about one in five people over age 65 will die.

Exercise has long been thought one of the best ways to prevent bone loss, but recent studies show not all exercise is beneficial. Swimming, competitive cycling, and weight-lifting don't seem to help and may even hurt. No one knows exactly why, but one possibility for finding bone loss in swimmers and cyclists is the intensity of their training. Long, high-intensity training sessions could result in lowered blood calcium levels due to calcium loss through sweating. This makes calcium supplementation very important to endurance athletes along with Vitamin D.

So, what does work? JUMP UP AND DOWN.

The bones apparently need a strong, fast impact to signal for increased bone development. Brisk walking is one of he best choices for older people whose bones are more delicate. For those wishing to maintain their bone density levels, jumping up and down is the simple answer. And, you don't need to do it for long -- 20-30 times.

Walking Healthy

Here is an interesting statement from a Psychology Today article:

Biking and rowing may get your heart racing, but a low-intensity stroll in the park 5-6 times a week is actually more effective in preventing obesity and eliminating heart risk factors including insulin sensitivity, total cholesterol, and blood pressure. Walkers trimmed their waistlines more and shed more weight.

The author recommends taking faster small steps, pushing off the back foot, and swinging the arms to set the pace.

I recommend walking and taking the stairs to all my patients -- both for easy stress reduction and for general health. Even for athletes, adding some meditative walking time can be helpful. Serious training is often stressful both to the mind and certainly to the body. Balancing that with easy walking and a quiet mind can be helpful.

Cordyceps and Ginseng to Boost Endurance

There are numerous herbs that boost endurance and stamina. Two of the best known are Ginseng and Cordyceps. Lots of research has been done on each of these. Ginseng has been around (in differing forms) for thousands of years and used as an anti-aging herb and Qi (energy) tonic. It is also famous for promoting virility. The variety called "American Ginseng" is highly prized because it is a balanced herb that isn't too fiery hot and safely boosts energy and stamina for almost anyone. The root of the plant is used medicinally and large, mature, wild-crafted roots can cost hundreds or thousands of dollars, but it is also raised on herb farms, making the supply more reliable.


Standard descriptions of Ginseng call it an 'adaptogen' -- an herb that strengthens the body and helps it return to normal after prolonged stress. It is going to be especially useful for someone doing prolonged sports training -- as in marathons or bike races.

A more unusual herb is Cordyceps. The description of this one sounds especially unappetizing -- it is a fungus that grows on silkworms. I always wonder how anyone ever decided to try this as a medicine, though it sounds better if you call it a mushroom. It has been around since at least the 15th Century.

Here is a quote from Wikipedia on the subject:


Outside the East, the world was largely unaware of cordyceps. This changed when the fungus caught the world's attention due to three female Chinese athletes, Wang Junxia, Qu Yunxia, and Zhang Linli. These athletes broke 5 world records for 1,500, 3,000 and 10,000 meters in 1993 at the National Games in Beijing, China. The amount of new world records being set at a single track event caused much attention and suspicion. Following the races, the women were expected by some to fail drug tests for anabolic steroids. However, the athletes' tests revealed no illegal substances, and coach Ma Junren told reporters that the runners were taking Cordyceps at his request.

I use a formula based on this herb regularly myself and recommend it to many patients. If you are an endurance athlete, it is definitely worth giving this a try.
