The scientific definition of speed is how fast an object is moving. Speed exerted on the human body can affect it in many ways. It affects the the body through the respiratory and the circulatory system.When speed was applied into the human body, it was noted that the heartbeat of the body had increased. The breathing rate also increased showing that indeed, force does make the body work harder. Speed was obtained by performing an exercise that required force. The faster the speed, the more the body worked and more the heart rate and the breathing rate increased. …show more content…
The first trial conducted started at only three miles per hour. Not much work was implied on the body therefore not increasing the heart rate and breathing rate much. For the second trial, the speed was increased by two miles to five miles per hour. A bit more of force was used, putting the body to work a bit harder. Since the body was working harder, the heart rate, along with the breathing rate, increased. The third and final trial, the speed was increased up to seven miles per hour. As the body worked even harder than before, the heart rate increased and also did the breathing rate. This proved the theory that speed could impact the body and increase the heart rate and also the breathing
