1. Discuss the relationship between distribution of muscle fiber type and performance. How might exercise training modify or change a person’s fiber-type distribution? Skeletal muscles contain multiple fiber types that are distinguished by their different myosin ATPase speed‚ and the development of their SR. The two main fiber types are type I and type II fibers. Type II fibers have a faster ATPase and a more developed SR than type I fibers. Type II fibers are also part of a larger motor unit‚

Muscle fatigue is weakness or weariness resulting from exertion or prolonged stress and the failure to maintain an expected power output. (Amussen) The process by which your body produces energy is called glycolysis. During glycolysis‚ glycogen is broken to produce creatine phosphate‚ which releases energy. The energy released catalyzes a reaction to produce ATP. The ending product of glycolysis is lactic acid‚ which is created by breaking pyruvate acid down. Then lactic acid is broken down to produce

------------------------------------------------- LIST OF MUSCLE INJURIES Properly functioning muscles perform only one duty‚ contraction. Muscles enable the body to sit‚ to move and to stand upright. They are attached by way of tendons to bones. Their contraction is controlled by electrical signals that can either be voluntary‚ such as when a person decides to stand up‚ or involuntary‚ as with the muscles that expand and contract the chest to control breathing. Muscles are made of thousands of muscle fibers. Knowing the types

isolated frog muscle could be made to contract when the sciatic nerve was irritated with a metal object‚ conducted the first muscle experiments between 1661 and 1665. Later‚ between 1737-1798 Luigi Galvani determined that frog muscle responded to electrical currents. The kymograph‚ which was invented in the late 1840’s lead to the revolution of experimental physiology because it enabled muscle contractions to be analyzed and recorded. The muscle cell or fiber is the basic unit of a muscle. The frog gastrocnemius
