-Effect of exercise on the musculoskeletal system
As Andre began to exercise, this had an effect on he’s bones; this is because he was putting more stress on them than usual which resulted in them getting thicker. Also exercise had an effect on he’s joints because the joints now became more flexible and he wasn’t getting anymore pains during or after exercising which was an improvement for him. A short term effect that Andre was capable of noticing is that his muscles was getting more flexible as he continued to exercise, this prevented him from getting any injuries, also it helped he’s performance. Another effect is the range of movement; this is because as he continued to exercise his body got used to the stress it was being put under which led to the synovial fluid becoming less viscous. Additionally for the long term effects, Andre’s muscles was capable of tolerating lactic acid; this effect was noticed when Andre stopped complaining about the stitches he got in his legs while exercising. He stopped complaining because his muscles were using fat as a source of fuel when there wasn’t any oxygen available for the muscles. Also Andre’s muscles weren’t getting bigger but it was increasing in its strength; this is because of the training methods used for his six week training programme.
-Effect of exercise on the cardiovascular system
When Andre was exercising, a lot of he’s energy was getting used up quickly. This energy is gained from the oxidising glucose; this means that not only oxygen must be delivered by the blood but it has to deliver glucose too. This resulted in Andre’s heart having to work twice as hard in order to pump more blood around the body. As Andre continued to exercise his heart muscle and cardiovascular system became more efficient which resulted in him improving he’s endurance because he was capable of running longer as more blood was circulating the body quicker than before. Additionally a short term effect which affected Andre while he was exercising is that he was gasping for more oxygen which led to him inhaling more oxygen than usually which caused carbon dioxide to be exhaled rapidly. Plus another short term effect that was noticeable was his heart rate which increased rapidly; this is because he was exercising harder than he normally does, also he was doing these exercises for a long period of time. Whereas the long term effect which was noticeable was the way Andre’s heart rate was decreasing quickly; this was because his heart was getting used to the regular exercise, also his heart was getting healthier and fitter. Another effect is that Andre was capable of increasing his aerobic capacity as his body adapted to the regular exercise which resulted in his heart and lungs becoming more efficient.
-Effect of exercise on the respiratory system
Andre’s respiratory system is affected by exercise because when he was actually doing the different exercises, his muscles needed more oxygen and for carbon dioxide to be produced so that he’s heart can work quicker and he would be capable of breathing faster and deeper to let the carbon dioxide exit quicker and the oxygen enter and be pumped around quicker. A short term effect that was noticeable is when Andre’s breathing rate increased; this is because of the chemoreceptors which are found the blood vessels and sensed a sudden rise of the level of carbon dioxide in the blood. This also caused the depth of Andre’s breath increased. Another short effect is the increase in tidal volume; this is because Andre is breathing more as more air...
