Title: Homeostatic response to exercise.
Introduction
In this experiment, it investigated the body’s homeostatic response to exercise. Homeostasis is the process of maintaining a stable internal environment regardless of changes in the external environment. The experiment explored how the body changes during exercise, as each system within the body attempts to create enough energy to continue exercising.
Exercise affects the body’s temperature, breathing rates and heart rate. The body has an automatic response to maintain these factors. During exercise, the body tries to maintain enough oxygen in order to support working muscles; this requires more oxygen which causes people to breathe faster during exercise and it also increases heart-rate. Body temperature also increases, as when food is converted into energy during exercise, heat is produced as waste, and this is maintained by vasodilatation.
Aim: Conduct a scientific investigation on the body’s homeostatic response to exercise.
Hypothesis: Exercising will have immediate effects on heart rate, breathing rate, and body temperature. Body …show more content…
The results started at 88 and increased to 140 beats per minute after 4 minutes of exercise. However the heartbeat decreased slightly by 5 beats per minute after 8 minutes of exercise. This is most likely because the subject slowed down her pace. She wasn’t working her body as much so the breathing rate had adjusted to suit the body’s needs. Heart rate drops when there are reductions in pace (PT Direct, 2016). But after 12 minutes of exercise, it increased by 15 beats per minute. The heart rate increased during exercise due to homeostasis, as working muscles need more oxygen. This causes the heart to pump more amounts of blood to working muscles. This distributes blood and nutrients to the muscles (Livestrong,
