Dustin Lee Exercise Lab Block C: Biology Introduction: In this lab, we learned about how the body and the heart react to increased movement as opposed to the resting stages. The purpose of this lab was to learn about how much exercise affects the heart rate. In this lab we tested how fast our resting pulse rate was and then we exercised and checked on the recovery rate. Analysis Questions: 1. You should not use your thumb when counting your pulse because a pulse can also be felt from the thumb. So you may get confused from feeling two pulses. 2. The heart beats faster because the brain (medulla) notices an increase of carbon dioxide. So the medulla tells your body to breathe faster and to pump the heart faster to get the oxygen to go through the body faster. 3. By exercising, the heart becomes accustomed to the stress of beating fast. Also by exercising, the heart becomes stronger so that less beats per minutes are required to do

Unformatted text preview: daily activities. 4. Max Heart Rate: 205 5. Lower end of target heart rate zone: 143.5 6. Upper end of target heart rate zone: 164 7. If you go above the heart rate zone, the heart may stress itself out which results in damaged muscle. Also, if it goes above the heart rate zone, then there should be a point where there is not enough oxygen in the body and the body may shut down until oxygen levels are back up. Conclusion In conclusion, the heart’s reaction to exercising varies from person to person. The body responds to exercising by testing the levels of carbon dioxide and increasing the heart rate when necessary. Heart rate zones are important to abide by because they determine where it is most stable for the heart to be pumping at....
