LEARNING AIM A: KNOW ABOUT THE SHORT-TERM AND LONG-TERM ADAPTATIONS OF THE BODY'S SYSTEMS TO EXERCISE.
There is a increased production of synovial fluid at the synovial joints, this happens because we need to produce enough fluid to in our cell membranes, situated at synovial joints. This increases the range of movement at the joint, which is another short term effect.
MUSCULOSKELETAL SYSTEM!
1A.1, 2A.P1, 2A.M1 : Outline, describe and explain at least two ways as to which the musculoskeletal system responses to short term exercise.
Short term effects:
Long term adaptations:
Muscle hypertrophy, this means there is a greater muscle mass compared to before,this occurs because our microfibres are put under stress so they tear then, the fibres are rebuilt into stronger microfibres and overtime thi increases you muscle mass.
There is an increased rate of metabolic activity this happens because, to supply our muscles and organs with oxygen and energy there are two processes, haemoglobin and metabolic activity. Haemoglobin is the process of oxygen turing into energy, and metabolic activity is the process of food turning into energy. During short term exercise, our rate of metabolic activity increases due to increased demand for oxygen and energy at our, muscles and organs.
Over short term exercise, our muscles tear muscle fibres and rebuild themselves into stronger muscle fibres and this increases the density of the muscles.
Long term we have stronger tendons and ligaments, this allows our body to be more resistant to injury, due to the fact our bones and muscles are more strongly connected.
Increased stability of joints, this happens because our joints are in constant use, making them more flexible and stable. Our posture is also improved because our bones and joints have new formation and they grow in a stable way to improve our posture.
