Musculoskeletal response:
Increase blood supply: The increase in blood supply might happen as your body starts to work more efficient than usually . The blood supply has to increase because the blood has to go to the parts in your body which you are exercising the most .For example: If you go for a run, the blood supply will increase because your legs will need more energy, therefore there will be more blood going into your legs than normal because you are overworking them.
Increase in muscle pliability: During acute exercise your muscle pliability increases which allows a greater range of movement which helps to reduce injuries.
Increase range of movement: the short-term effect of exercise on your skeletal system which is demonstrated by changes within joints. The movement of joints stimulates the secretion of synovial fluid. The range of movement at the range of movement at the joint increase and this fluid also becomes less viscous.
Muscle fibre micro tears: During exercise, your muscles are put under stress to the point that tiny tears occur in the muscle fibres. These are what micro tears are causes by swelling in the muscle tissue in that cause pressure on the nerve endings and pain. Training is the only way to improve if the body has sufficient fuel and rest in order to repair this micro tears, making the muscles a little bit stronger than it was before.
Sporting example could be GYM when working you muscles for long time you feel the pain however this pain, needs a bit of time because you did weight lifting for few weeks in a row so you will need space of 3 days to require and then you continue with your weighting lifting, that is how your muscles get bigger
