Musculoskeletal And Energy System Essay

The musculoskeletal and energy system. The musculoskeletal system is made up of muscles, bones, ligaments, tendons and cartilage. Each part of the musculoskeletal system is controlled by the nervous system, an impulse from the nervous system results in a contraction of muscle, shortening it, causing the bone to which it is attached to move. The musculoskeletal system aids movement of the body, as well as helping to maintain posture as well as the production of heat

If an Athlete takes part in acute exercise, the musculoskeletal system responds in a number of ways. The muscles increase in temperature and metabolic activity as a short-term response to acute exercise and this accordingly increases the demand for oxygen, a demand that is met through capillary dilation to increase blood supply. The muscles warm during any form of exercise as to make them more pliable and so to reduce any risks of injury; this is known as an increase in muscle pliability. Movement of the joints

A constant supply of energy is available to the body in the form of ATP; ATP is made up of three phosphate groups and a base and is formed through a reaction between a phosphate molecule and between adenosine diphosphate. The storage and release of energy is associated with the chemical bonds that takes place in the molecules; when a bond is made, energy is stored, and when broken, energy is released. Energy is stored when ADP binds with another phosphate, and when combined with water, it splits and energy is released. The body has two options in terms of the availability of energy, there is the energy system which is aerobic and involves oxygen so is appropriate for longer more moderate exercise, or anaerobic which does not involve oxygen and is hence appropriate for activities such as
