Look at the effect exercise has on pulse rate and respiration rates.

Extracts from this document...


Biology coursework Introduction For my investigation I am going to look at the effect exercise on pulse rate and respiration rates. For my investigation, I have decided to look at the effects of a running exercise. Before commencing the experiment safety measures need to be considered: * Suitable footwear - e.g. training shoes, these are to protect the feet and provide a non-slip environment on the steps. * Suitable clothing - e.g. shorts and t-shirt, these are to provide comfort At the time of the experiment I am ensuring the participant is fit and healthy and that warm up exercises are carried out prior exertion. In considering variations to the experiment walking and running will be compared over different intervals. Prediction From my scientific knowledge I predict that the rate of respiration will increase as a result of exercise. ...read more.


I will then measure my pulse rate and my resps aswell. I will wait till my pulse rate retreats back to its resting level; this is to keep it a fair test. When it is back to normal I will add another 15 seconds each time onto the last time and measure my pulse n resps. After continuing this process till I have walked for 120 seconds, I will do the same experiment but instead of walking I will run instead. To make sure that this is a fair test I will walk up and down 15 steps, this is so that I walk the same amount of distance. I will also wait till my pulse goes back down to its resting level this enables us to record accurate results for measuring the effects of exercise on pulse rate. ...read more.


Evaluation Although I believe that my experiment produced fairly valid results, I am not sure that my experiment was particularly accurate. For instance, I cannot be sure that the running and walking was done at the same rate throughout the experiment. Also, I am not sure that the 15-second intervals were kept exactly to this timing. If I were doing this experiment again I would have to look closely at the method of exercise I used. I think that exercising on a piece of equipment like a running machine would produce more accurate results because I would be able to guarantee that the exercise remained constant throughout this experiment. Finally, an actual 'pulse-meter' might have helped the experiment to be more accurate. This is simply strapped round the chest of the exercise and it measures your current heart rate. I believe that this would produce a more accurate heart rate and destroyed any necessity to have the 30-second breaks during the exercise. Matthew Fisher ...read more.

    The human body is powered mainly by glucose. This is a sugar you get by digesting starch and other carbohydrates in your food. Before glucose can be respired, it has to be broken down into a simpler substance, pyruvic acid. This travels to the cell's mitochondria, where it is combined with oxygen to produce carbon dioxide and water.
