Introduction; Procedure

The three different conditions of activity consisted:

- Having a student volunteer laying down at complete rest for ten minutes.

- Having a student volunteer do a light activity for five minutes.

- Having a student volunteer do intense activity for five minutes.

After each activity the metabolic rates were measured as quickly as possible using: oral

thermometer, ordinary thermometer, sphygmomanometer (blood pressure gauge), piece

of microscope tissue (for sweat), stethoscope.

- The oral thermometer should use cover slips and/or be disinfected with mouth wash before
each use.

Hypothesis

Not everybody reacts the same way to exercise
My hypothesis to this lab is that all the rates increase as the level of activity increases. The results for activity 1 will be farley low compared to the results for activity 3 especially for the heart beat and blood pressure. I think there will be a big difference between activity 1 and activity 3 because when you’re at rest, your body needs less energy and the body temperature shouldn’t increase, but when you’re in heavy physical activity you breathe faster as you your muscles will need more oxygen. Breathing faster will make your heart beat faster in order for the oxygenated-blood to go through all your body and since there is going to be more oxygen needed the heart will have to pump faster. The internal temperature, I think will not change at all, but the external temperature, in my opinion, will increase as the level of activity will get harder as more will be given off.
