Fatigue plays a major part in the sporting performance of the athlete both in physical and mental terms. The athlete needs to learn to notice the signs of fatigue and tension that arises from this and introduce methods to cope with the debilitating effect it can have on their performance. Muscle fatigue and the tension associated with it can result from a number of different factors. The athletes may simply have over exerted themself physically in training or competition leading to muscular fatigue

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

Animals have three types of muscles; skeletal‚ smooth‚ and cardiac. This lab however is only concerned with skeletal muscle. A special characteristic of skeletal muscle is their ability to contract or shorten via thin (actin) and thick (myosin) filaments (Flanagan‚2017). This gives a striated appearance which is a key distinguishing characteristic between other types of muscle (Flanagan‚2017). Skeletal muscle is also multinucleated. Skeletal muscle needs plentiful amounts of energy to be able to

Q1 Muscle contraction can be understood as the consequence of a process of transmission of action potentials from one neuron to another. A chemical called acetylcholine is the neurotransmitter released from the presynaptic neuron. As the postsynaptic cells on the muscle cell membrane receive the acetylcholine‚ the channels for the cations sodium and potassium are opened. These cations produce a net depolarization of the cell membrane and this electrical signal travels along the muscle fibers. Through
