Describe the musculoskeletal and energy systems response to acute exercise.
What is an acute response?
An acute response is an immediate response to exercise.
Acute exercise will last throughout the full length of your training session. During the training session our bodies begin to respond to the exercises we are doing and begin to feel the changes within our bodies and mind due to physical strain and stress of the physical activity in lots of different ways.
Musculoskeletal response
Increased blood supply: the increased blood supply occurs in the body due to the increase in demand for more oxygen and this is due to the working muscles needing more oxygen and energy during exercise. With there been an increase in blood supply that means there will be greater amounts of oxygen been delivered around the body at a faster speed due to the heart pumping blood around the body at a faster pace.
Increase in muscle pliability: Muscle pliability is the stretchiness of your muscles and connective tissues. When muscles become warm they become more pliable and this helps reduce the risk of an individual becoming injured during exercise and this is because the muscles contract quickly when the body is exercising. When the muscles are contracting they produce heat which then a=makes the muscle more pliable. The warmer the muscle becomes the further you can stretch it each time without the muscle becoming weakened or injured.
Increased range of movement: Synovial fluid is the result of joint movement and allows joints to move without them rubbing together and causing friction. During exercise joint changes occur and this is because the synovial fluid becomes less viscous (the measure of thickness of a fluid) so therefore the range of movement at the joint will increase.
Muscle fibre micro tears: When muscles are put under pressure whilst exercising tiny tears occur. These tears within the muscles cause swelling,
