The two main processes involved in muscle contraction are cross-bridge cycling and the length-tension relationship‚ which normally function to maximize contraction in the muscle. Beginning with the activation of a motor unit‚ the ions flow from the motor unit towards the muscle fibers that it innervates by the motor neuron in the same way as a normal muscle would. However since the tissue is damaged‚ the force that is generated by these muscle fibers will not be as great‚ leaving the fibers less

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

Muscle Fatigue Monira Begum How muscles work and get the energy they need to work. Muscles need energy to work and move. (1) Their main source of energy is glucose. Glucose is made of a number of different types of carbohydrates (usually sugar) as well as milk and fruits. Glucose turns into other chemicals such as water and carbon dioxide which releases energy. (2)Your muscles get warm when using or burning energy. Glucose is sent to muscles through red blood cells; this is how muscles get
