Fascia Stretching

As I am renewing my fitness training license and reading the High-Performance Training for Sports book, I will also review what fascia is, as well as tendons and interior muscle fibers and how one can work those out. I think most exercises and sports do not strengthen, elongate those parts.

I am not sure of the scientific validity of the below Web sites,but it seems fascinating. I will keep checking on fascia and stretching it. He claims that injuries are "stored" in fascia,when they are stretched, you get rid of parts of them in sweat,urination and defecation.

It seems that paying attention to fascia,tendons and inner muscle fibers would take fitness, dance and team sports to a  new level. However, the authors mention that too much fascia stretching may reduce strength. This varies by the individual. Studies, they wrote, are not consistent, well-designed of conclusive.

Hey, I never heard of this. I am updating my ISSA fitness trainer license and read about this in High Performance Training for Sports by David Joyce and Daniel Lewinson.

There are pros and cons. Here are some and a demonstration video.

Single-Leg Hip Rotation for Abdominals, Plus Variation

Stand with your legs shoulder-width apart Cross your arms at your chest for stability. Start with either leg first for four sets of 10 repetitions. Bend the knee 90 degrees. Both knees are facing forward at this point. Rotate your leg outwardly until your knee is 180 degrees to your hips. Return to the starting position. Repeat for four sets of 10 repetitions. Then do the same with the other leg. Breathe out when you rotate your leg away from your body and breathe in when you brig it back to center.

Variation:

Start in the same way. When your leg is in the 180 degree position, bring it straight down to the floor. Your feet will then be in a 90 degree position with each other. Turn your foot to be straight with the floor that was already on the floor. This will activate your gluteus maximus and all your abdominals, including the opposite side obliques. Repeat for four sets of 10 repetitions. Then do the same with the other leg. B
