The Effect of Exercise on Pulse Rate

I am going to walk for exactly one minute, and after that minute, I will measure and record my heart rate 3 times, also for one minute. I will rest for 5 minutes after each exercise in order to get my heart rate back to its resting pace. After my heart rate is back to its normal resting pace, I will take my second exercise, which is a light jog. I will lightly jog continuously for one minute, stop and take my heart rate for one minute and then do the same process another two times. Then finally I am going to do hard running for exactly one minute, and after that minute, I will measure and record my heart rate 3 times, also for one minute.

Effect of Excercise on Pulse We are trying to find out the pulse rate when doing exercise by testing the pulse at rest then doing exercise and then every minute afterwards for 5 minutes observing how the rate is affected. Prediction ---------- I think the heartbeat will get faster the harder you exercise because you need energy for your muscles so you need to breathe more, and send more blood around the body to generate energy by respiration. Method ====== First we're going to test the pulse rate at rest on four people two boys and two girls, then they are going to walk for one minute and test the pulse five times (every minute) after exercise. We are doing this three times (3 tests), so that we can calculate an average result to improve accuracy. This will then be done again for jogging then running with four people being tested.

The first run will last a minute, and then the second, 2 minutes, the third, 3 minutes, the fourth, 4 minutes and the fifth run will last 5 minutes. We will make it a fair experiment by using a boy and a girl of roughly the same height, Tom is 153cm tall and Lauren is 150cm tall. The same flight of stairs will be used for each run and they will be keeping the pace constant throughout the experiment. The pulse rate will always have to be the same as the resting rate measured at the start before they can start the next run. The equipment need for this experiment is a flight of stairs (20 steps), a stopwatch, a Boy and a Girl of roughly the same height and build and a small chart to record the results.

Your pulse is just an indication of your heart rate as your arteries expand each time the ventricles pump blood out of the heart. Your heart speeds up to pump extra food and oxygen to the muscles. Also increasing the physical activity will slow down the recovery rate because there is more lactic acid, due to anaerobic exercise, to convert to Carbon Dioxide and water and for this oxygen is needed which the heart has to pump. Plan ---- I plan to conduct an experiment that will allow me to obtain results in which I can analyse in a clear way. My experiment will take place in a gymnasium in room temperature.

Prediction. I predict the harder someone exercises, the higher his or her heart/pulse rate would be. The blood has to be pumped round the body quicker by the heart. There are several reasons why this happens. Before and during the early stages of exercise the sympathetic nervous system is alerted and adrenaline is secreted in to the bloodstream.

For one to continue exercising for long amounts of time, cells need to create ATP in order to use energy. Oxygen must be present for the process of creating ATP, which not only explains why higher respiratory rates occur during exercise but also faster heart rates. When the heart is beating rapidly, it is distributes oxygenated blood as fast as the body n... ... middle of paper ... .... All things considered, this experiment was conducted as well as it could’ve been, unavoidable errors and all. Even still, there are still things that could be discovered throughout this topic. There are multiple possibilities for future research.

Remember you will only get the results you truly want, if you put forth the effort. At times this is aggressive, if it becomes too much for you, scale it back. Not only will you extend time on the machine, but you will vary the program and intensity, along with utilizing various pedaling directions to keep your muscles from getting too comfortable in a specific routine. Once you get past the first two days of the program you will incorporate random burst of speed to jump-start your metabolism. Throughout the entire program your resistance levels will fluctuate, in order, to maximize your results.

The Effect of Exercise on Heart Rate Aim: In this investigation I am trying to find out if exercise have any effects on the heart rate. Prediction: For my prediction, I predict that as the amount of exercises increases, the heart rate will increase too. Background: More energy (Oxygen and glucose) is needed to pass to all different kind of muscles as you do a certain amount of different exercises, so more blood is needed to run in the circulatory system, therefore the heart rate will go up. Variables: The results can be affected by the following things, the change of amount of exercises, the change of time for exercising and resting, the change of temperature and the change of person and their health. Input variables: The input variable will be the time of exercises.

I will first exercise for 15 seconds then measure my pulse rate for 15 seconds then rest for 2 minutes then repeat the process. I will do this 3 times then increase the amount of time I exercise for to 30 seconds and do the same but exercise for 30 seconds. I will increase the amount of time I exercise for by 15 starting from 30 then, 45,60,75 and then 90 seconds. I will make sure results are reliable by repeating them if they are slightly unreliable. I predict that as the amount of time I exercise for increases so will my pulse rate.

Although I will not calorie count I will still portion out all my meals and snacks. As for my workout regimen, I want to exercise at least 5 times a week and take two rest days. The workouts will be different everyday and focus on specific areas , the three different workout patterns will be back and biceps , legs and triceps and shoulders and chest. I will do this pattern for three days and then take a rest day and do another series of the pattern. By scheduling them like this I can make sure every part of my body is getting toned.
