The Physiology of Fitness

AIM

Collect physiological data to investigate the effects of exercise on the musculoskeletal, cardiovascular, respiratory systems.

HYPOTHESIS

While getting our results, I expect to see a variation of finding from musculoskeletal, cardiovascular and respiratory system. I expect to find that the muscles will expand during exercise due to the swelling from the micro tears. I will find that during exercise that the subject heart rate and blood pressure will increase due to the body needs for more oxygen therefore the heart will pump blood around the body faster. The breathing rate will increase as well as the body needs to replace the extra oxygen used during exercise.

METHOD

Before we started to collect the data from the subject we recorded resting blood pressure, muscle size, pulse and breathing rate. After we recorded these we made the subject play badminton to see how it affected the different functions in the body. We measured the four different areas every 5 minutes for half an hour to see how the longer you exercise if has different effects on the body. To measure the blood pressure we used a Blood Pressure Monitor, A Velcro strap is wrapped around the subjects arm and the monitor is set to 150. The machine squeezes the arm and reads how much pressure the blood is pumping around the body. We measured muscle size by using a tape measure around the thigh and bicep to see what the circumference was; we did this to see if short period of exercise still affected the size of the muscle. To measure the pulse and breathing rate we made to subject count their pulse and breathing rate for 15 seconds and then we multiplied that by 4. We did the same measuring techniques during the other 2 fitness sessions but the subject was made to use the tread mill or use the bikes the next session was on the resistance machines e.g. rowing.

RESULTS

My results show what I expected from the subject, there are very few anomalies with the results and I believe there were quite...
