Document Summary
A lot of muscle damage from eccentric contractions- muscle being pulled apart. 1. hamstring at shortest length during the stride. 3. continuing to extend lower leg so hamstring lengthens more. Initially fleeting hip, then start to extend the hip as the hamstrings continue to extend. In 1st few (3-6) seconds, atp pcr system getting energy very fast, then go to glycolysis. When you switch energy systems, go through many runs and go from pyruvate to lactate. When you switch energy systems, contraction and relaxation of the muscle fibres is related to. As you spring and switch systems, atp production is lower but still running at the same speed- this is when people mostly get injured review: Effects of genetic expression on fibre composition more prominent for identical twins. Monitoring rate of change in length of shortening, rate in charge. In muscle spindles them selves, have contractile areas, and centre portion has sensory nerve fibres associated.
