Question: How do various factors affect muscle fatigue? Introduction: In this experiment muscles will be tested with weight‚ to see if weight is truly a factor in muscle fatigue. Muscle fatigue is the muscle’s ability to contract exert its normal strength due to physical stress upon it. The structure of a muscle include a thin layer called epimysium which surrounds the entire muscle‚ deeper to the epimysium is the perimysium. This layer contains fascicles which are bundles of muscle cells. In

MUSCLE FATIGUE HOW DO MUSCLES GET THE ENERGY TO WORK? In muscles‚ it is essential that Calcium is present‚ as this gives the muscles the ability to contract and relax. For muscles to contract energy is needed: the energy can only be provided by the breakdown of a chemical called adenosine triphosphate (ATP). As ATP is broken down‚ a phosphate molecule is broken off‚ reducing the phosphate molecules‚ from 3 to 2. This produces adenosine triphosphate. However for the muscles contraction to continue
