What effect does exercise have on your body?

Extracts from this document...


Ben Oates 11M What effect does exercise have on your body? Trial Run : Aim : To see the effect that exercise has on your pulse rate. Method : 1. Take pulse rate at rest. 2. Skip on the pot for one minute. 3. Take pulse every minute for five minutes, after. 4. Repeat steps 1-3 increasing the skipping time by one minute each time up to five minutes. Results : From these results obtained in my trial run I can see that many results are anomalous and do not seem to fit into a steady pattern. For my investigation I will attempt to obtain clearer and firmer results that fit into a pattern. I will be doing this by making sure we use the same person for all the skipping as we did not do this for the trial. I am also going to change the table by attaining two results for each time and only measure the pulse rate straight after the allotted time minusing this from the rest to get and change then we will work the average out of the two results as it will be easier and clearer to plot onto a graph. Aim : To see the effect of exercise on your pulse rate. Hypothesis : I predict that the pulse rate would increase with the exercise. ...read more.


To do this the respiratory rate has to increase to get more oxygen. In aerobic respiration we also use glucose with the oxygen to give us more energy. If we do not have oxygen in respiration then it is called anaerobic respiration, this is our short term energy system for when our muscles are working at a hard for a short amount of time e.g. Sprint runner. As we do not have oxygen in this we use our body stores of Adenosinetriphosphate (ATP) to give us energy. However this runs out after a while and we use Adenosinediphosphate (ADP) and glycogen in our body to create more this gives a waste product of Pyruvic acid and if oxygen is not put into this then we have the final product of lactic acid. In the first two or so minute of exercise we use our Creatine Phosphate (CP), from then till about five/six minutes we use our anaerobic system from then on we use our aerobic system. Our creatine phosphate does not use oxygen as it is fuel that our body already has, if we go over the creatine phosphate supply we go into anaerobic respiration. This is our short term energy supply. Also known as our lactic acid system. It uses ATP to give us energy this energy gives us ADP which uses glycogen to give us ATP and pyrovic acid and as we have no oxygen it this goes to lactic acid which can lead to tiredness, muscle cramp and fatigue. ...read more.


Anaerobic respiration is also the process where useable energy from glucose without the need for oxygen. Evaluation : I think my results are quite accurate although we have an anomalous result for our five minute exercise which we marked on the graph. You can see they are quite accurate by looking at an aerobic respiration graph this is another reason that we knew that one of the results was anomalous. I feel it could of been anomalous for a couple of reasons one being that the skipper could of stopped through the exercise time, skipped slower or may of waited to long after the exercise to take the reading. If I was to do this investigation again I would gather more results as it would lead to a better average as was proven with our anomalous result which brought the average down so did not give us as accurate results as I would of hoped but they still showed us what needed to be shown. I would also give the skipper more time to recover in between skips as I do not feel we gave him enough time to repay his oxygen debt properly which can lead to high results. Although I feel that to give a more detailed conclusion I could include how a training regime or diet could affect the pulse of certain people. Overall I am happy with the way this investigation went as my Hypothesis was correct. ?? ?? ?? ?? ...read more.

The brain senses that this is happening and it sends nerve impulses to the heart making it beat faster.

    In general, the main factors affecting heart rate at rest are fitness and state of recovery. In general, fitter people tend to have lower resting heart rates. For example, Martin Hanford has an average heart rate of 28 bpm. The reason for this is that, with appropriate training, the heart muscle increases in both size and strength.
