effect of a warm up on skeletal muscle tissue in relation to speed and force of contraction
...he muscles contract faster. With the reduced frictional forces between the muscle fibres which therefore increases the muscles contractility and contraction force. When a muscle contracts its antagonist relaxes to enable movement. As the antagonist is lengthened to a point where injury may occur, the Myotactic reflex causes the muscle to contract to protect itself. When the body temperature is lower then average (due to cold temperatures) the Myotactic reflex is sowed making it an inefficient protective reflex and so increasing the risk of injury. With a correct warm up this protective reflex can be made more efficient and effective. This reflex allows you to respond with more speed and force of contraction. Warm Ups are beneficial to the cardiovascular system as they slowly increase the heart rate and dilate the blood vessels allowing a greater volume of oxygen to be exchanged with carbon dioxide in muscles. The intern increases the metabolic rate so that your muscles can work faster and with a greater force of contraction. This increase in dilation of blood vessels helps with the removal of lactate from the muscles. The removal of lactate reduces stiffness and allows faster contractions. As the temperature of the athletes body rises the nerves sent from the brain to different parts of the body are also travelling quicker resulting in the speed of contraction happening faster. The elasticity of tendons and ligaments is now greater as there...
