Document Summary
When we do physiological tests in exercise physiology, we look at skeletal muscle features. Specifically, they examine muscle fibre type, glycogen concentration, and metabolic capacity of skeletal muscle. The percutaneous biopsy technique will be examined on how we assess skeletal muscle functioning in kinesiology. This biopsy technique can be studied through: biochemistry, histochemistry and gel electrophoresis. Describing the percutaneous biopsy technique physiologists will locally anesthetize the muscle with 3 cc-xylocaine, which causes a mild, burning sensation to the individual. Once anesthetized, a scalpel blade makes a 1cm incision through the skin and fascia to take out the muscle. We can determine the muscle"s contractile ability by sampling the thickest area of the muscle. The biopsy needle looks like a straw that draws the muscle in through the sharp end. When the needle is inserted into the muscle, it must be perpendicular to the muscle fibres.
