Developmental Movements: Part Two

In the previous post I pointed out that the developmental movement patterns learned in infancy are building blocks for the more complex movements that we use in our daily lives as adults. These simple patterns are combined to form sophisticated movements, just as words and letters are combined to make sentences. One implication of this… Read More

Extreme Performance or Optimal Health? Pick One!

Many of my clients will ask my opinion about whether a particular sport or activity promotes movement health. Yoga, running, swimming, weight training, ballet, soccer, gymnastics, crossfit. (People are especially interested in whether these activities will be healthy for their kids.) It’s an interesting question because almost any physical activity you can think of has… Read More

The Effect of Fatigue on Coordination

I just read the abstract of a study cited by Chris Highcock at Conditioning Research. (By the way if you are interested in either strength training or hiking, check out Chris’ excellent new e-book called Hillfit.) It is one of many studies that show that muscular fatigue impairs coordination. Because coordination is essentially a mental… Read More

The SAID Principle and Transfer

After writing last week’s post on the meaning of strength, I was thinking about doing a post that would address whether getting “stronger” in the gym makes you stronger on the field. The big question is: to what degree will resistance training make you better at your sport? For example, will improving your deadlift make you better at soccer?

I have a previous post on the SAID principle which makes the point that exposure to … Read More

New Deadlift Record: Making the Impossible Possible

Benedickt Magnusson just set a new world record in the deadlift – 1015 pounds! Check it out below. This amazing demonstration illustrates many of the principles I write about on this blog. Here are just a few. First, I am reminded of one of my favorite quotes from Moshe Feldenkrais, who said that the purpose… Read More

The SAID Principle

Rafael Nadal’s huge left arm, courtesy of the SAID principle. The SAID principle is one of the most important basic concepts in sport science. It is an acronym which stands for Specific Adaptation to Imposed Demand. It means that when the body is placed under some form of stress, it starts to make adaptations that… Read More
