How Exercise Effects Heart Rate

Extracts from this document...

Introduction

How Exercise Effects Heart Rate Plan This experiment was conducted in a gym for testing out how exercise affects your heart rate. A pulse metre was strapped on to the chest underneath the test subject's nipple. The test subject had to leave it there throughout the experiment. A heart rate watch was also taken to measure the test subject's heart rate to conduct the experiment. A stopwatch was also used, which was built in the rowing machine. A rowing machine was used, to conduct the experiment. The test subject rowed the rowing machine at five different speeds for a fixed amount of time. There were many factors, which could have altered the results slightly or by a huge amount. While a person does exercise he should not be given any food to eat whilst doing any of the experiment, because ...read more.

If blood is lost then there will be fewer red blood cells to carry oxygen around the body and therefore, the oxygen debt would increase quicker and the subject would slow down. This experiment is also greatly affected by the person's stamina. Stamina is measured in how quick you can restore your pulse rate to normal. The more stamina you have the less oxygen your body requires to do the task you are trying to accomplish. People with more stamina on the whole have bigger lungs and more supple joints. This helps them breathe more air at a time, and they can supply their body with energy via respiration, which is the process of taking energy from the food you eat. ...read more.

Conclusion

If the room is too cold, the subject might start shivering of the cold and will then freeze up decreasing his efficiency; therefore the room temperature should be kept constant from twenty to twenty two degrees Celsius. As more work is done, your pulse rate increases. When it does your heart "beats" faster and struggles to keep a sufficient supply of oxygen to your body, so you use up more energy, then the oxygen debt increases and lactic acid is produced. Later your body takes energy from your food to supply your body's requirements and therefore keep your pulse rate as low as possible. As the work rate done doubles the oxygen intake that is required doubles and so does the required energy. The higher your pulse rate the more "unfit" you are, therefore the lower it is when doing a particular activity the "fitter" you are. ?? ?? ?? ?? Nixon Dhushantha 4A ...read more.

    So to make sure we do not count twice we will always count the first pulse of the two. Within a trial we have to keep the same person throughout. This is because every person has a different diet, fitness level, weight, stature or is a different gender.

    Independent variable BMI (body mass index) ? We need to change the BMI of the test subjects so that I can evaluate the effects it has on recovery time and moreover will contribute to the answer of my hypothesis. Not all variables can be controlled throughout the experiment.
