This experiment measured the change in skin temperature and heart rate of a chosen subject for four two-minute intervals of intense exercise. By averaging the data collected, it was found that the skin temperature of the subject decreased and their heart rate steadily increased during exercise. These two factors in conjunction kept the subject’s core temperature …show more content…
The low initial skin temperature readings of subject 2 forced their heart to pump faster to supply a greater amount of warm blood to the skin. Contrastingly, subject 1’s heart rate was much lower, as less effort was needed to maintain their internal temperature due to their increased skin temperature.
The high initial heart rate of subject 2 had a flow on effect during the actual exercise period. Subject 2’s heart rate raised to 120bpm at the two minute mark, before spiking to 204bpm at the four minute mark and increasing further to 208bpm. Unlike the beginning of the experiment, the low skin temperature most likely helped subject 2 in cooling their body during exercise. It is asserted that subject 2 may have experienced physiological stress if their rate of exercise was maintained.
Unlike subject 2, subject one’s gradual increase in heart rate and comparatively low maximum heart rate placed less stress on the heart and required less energy. It was asserted that this saved energy was directed toward cooling subject 1’s body, keeping internal temperatures within the optimal range during exercise and therefore maintaining homeostasis. (5
