Effects of Core Instability on Muscle Activity

January 15, 2019

Video

Potentially, an instability training program that first involves static balance and then progresses to dynamic balance activities would improve intrinsic balance. This improvement in balance would increase movement confidence, releasing the neuromuscular system from a stiffening strategy to more unimpeded motion, force, and power development.

Static Stretching and Performance

September 24, 2018

Article

Some research has found that static stretching can have detrimental effects on subsequent performance. This is not to say that static stretching should be eliminated from an athlete’s program, but it should be sensibly incorporated into the daily training regimen since chronic stretching can enhance the range of motion around a joint and potentially improve strength and power performance.
