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

Activities that require a quick burst of effort, such as sprinting, entails the body to produce large amounts of energy over a short period of time. On the other hand, activities like marathon running require a constant but slower rate of energy production over a long period of time. The body attains energy through the oxidation of food, in particular carbohydrates and fat, and when burned ATP, a molecule that is plentiful in energy and gives energy for muscle contraction when broken down. ATP is the only molecule that is able to supply energy for the contraction of muscle fibres and it can only be made by the phosphocreatine energy system, the aerobic energy system and the lactic acid energy system. The phosphocreatine energy system is the instant energy system; phosphocreatine is a high-energy compound and when there is a high level of exercise, this compound that is stored in the muscle is broken down to form ATP. The lactic acid energy system is one that supplies the body with energy in the short term; the ATP is made through a breakdown in fraction of the glucose and glycogen in the body. As with the phosphocreatine energy system, the lactic acid energy system is an anaerobic process and so is not a maintainable …show more content…
During exercise vasodilation takes place, in this process the arterioles dilate in order for the vascular section of active muscles to increase and hence increasing the diameter of the blood vessels resulting in an increase in an increase in the flow of blood to the muscles. In the same manner, the blood vessels can dilate and prevent the blood flow to tissues and therefore momentarily lessens their blood supply and so reduce the blood flow to the muscles; a process known as
