Laura Graceffa Core Science Case Study Does Exercise Improve Your Health? Does Exercise Improve Your Health? Contents Introduction Page 2 Scientific Evidence Page 2 - 3 Evidence For Page 3 - 5 Evidence Against Page 5 - 7 Conclusion Page 7 Bibliography Page 8 Introduction My case study is about finding out whether doing exercise can improve your health or lead to health problems. There are different views expressed which may suggest that not all exercise is good for you. I will present the evidence clearly and will have reference to their sources in the bibliography. But what does being healthy actually mean? Being healthy means having organs which work efficiently helping to prevent illness and disease. It is also gives a feeling of well being. Everything has risks to it including exercise, these risks can be dangerous and life threatening. My case study will find out whether exercise is a risk or beneficial to all. My report contains scientific evidence from a trustworthy source; evidence for and against the case study from numerous sources; a detailed conclusion showing comparisons between the evidence and my interpretation of my findings, and a bibliography. ...read more.


This information is not very reliable because even though it comes from a good source, we are not told how long the research was carried out for, what age the patients were, their health conditions or what exercise they took part in. It shows that each patient increased their oxygen consumption after the period of exercise. 3. The blood pressure research council state that even though many epidemiological studies have not show a correlation between exercise and blood pressure, they have concluded that exercise decreases blood pressure. They carried out an analysis on 105 overweight study groups which had their blood pressure monitored before and after they completed a course of weight training. The training showed "significant net reductions of resting and day time blood pressure of 3.0 to 2.4 mm Hg." This evidence is reliable because the researchers carried out their research on a large amount of participants who all had the same physical condition - high blood pressure. The findings show that over a period of time where exercise was brought in the participants saw dramatic changes in their blood pressure. The evidence shows that if you are overweight, exercise can help you to loose weight and decrease the risk of developing diseases such as heart disease. ...read more.


can weaken the immune system dramatically, making you more likely to become ill, because the energy which would have been used to fight disease is being used to increase fitness. 'Evidence for 3' can also be compared, to 'Evidence against 3' because collectively they refer to the effects of exercise on the blood - blood pressure and menstrual cycles. 'Evidence for 3' suggests that exercise carried out regularly can decrease blood pressure and improve health by lowering risk of heart disease. In spite of this, 'Evidence against 3' shows that over-exercise can lead to less than three menstrual periods a year, decreasing the amount of female hormones in the body, especially oestrogen. In my opinion and by summarising the information, I conclude that regular exercise can improve your health, by decreasing the risk of heart disease, stroke and other major diseases. It can improve your chances of living for longer and being happy throughout your life. It decreases depression. However, over-exercising or little spurts of exercising can deteriorate health and cause you to become more susceptible to disease. It can cause long and short term injuries which can cause depression and create the idea that exercise is not for you, increasing weight and risks of major diseases. ...read more.
