Short and Long term effects of exercise on the body.

Extracts from this document...

Introduction

?Muscles contract more often and more quickly. The more you exercise the more the muscles contract. ?Increase in the flow of blood to the working muscles. During physical exercise, muscles contract and expand laterally. The intramuscular pressure exerted on the veins by the surrounding muscle pushes blood through the one-way valves of the veins, returning it to the heart. ?Muscles take up more oxygen from the blood. If you are going to be exercising for more than a few minutes, your body needs to get oxygen to the muscles or the muscles will not function. Just how much oxygen your muscles will use depends on two things: getting blood to the muscles and extracting oxygen from the blood into the muscle tissue. Your working muscles can take oxygen out of the blood three times better than your resting muscles. Your body has several ways to increase the flow of oxygen full blood to working muscle: * increase blood flow to the working muscle * diversion of blood flow from non-essential organs to ...read more.

Middle

When you take part in an exercise or a sport your body moves more quickly. This also means that the joints need to work more. The tendons and ligaments surrounding the joint become stronger and then the joints will be more flexible. Bone width and destiny increases Bones are made from calcium. This is because the normal participants in weight bearing exercise helps to enhance the bone density. This then results in the bones becoming stronger. Increase in Synovial at the joints This is because the Synovial Fluid fluid prevents friction from occurring between the bones. The joint operates better when there is more synovial fluid. Joint hyaliane artciular cartlidge thickens Cartilage is found below and on top of the bones. Cartilage is their to stop the bones from colliding into each other. The thicker the cartilage is the better it is. Tendons and Ligaments surrounding the joints becomes thicker because the tendons are connected to the bones by fibres and ligaments which help stabilise the joints. ...read more.

Conclusion

Some examples of aerobic activities include: * Walking * Jogging * Bicycling * Swimming * Aerobic dancing * Racket sports * Rowing * Ice or roller skating * Cross-country or downhill skiing Long Term changes can be described as adaptations in the body as a result of long and regular participation in exercise. Short term changes are classed as responses to exercise ~ these are immediate changes that can be seen / experienced when we start to exercise. If you stopped exercising it could take perhaps only a fortnight weeks for any of the long term effects of exercise to go back to how they were before you started exercising. ?Size and number of mitochondria increase in muscle cells. Muscles become able to work harder for longer. ?Muscles increase in size (hypertrophy). * Higher O2 uptake in the muscle cells. * Increase in myoglobin in the muscle cells. * Muscles become able to work harder for a longer amount of time. * Hypertrophy happens to the muscles * Increase in lactic acid tolerance. * Muscle cells store more amounts of CP, ATP & Glycogen. * Bone becomes more stronger ...read more.

    of exercise on the cardiovascular system is a lower resting heart rate than average. Athletes who train aerobically and run long distances tend to have larger hearts, particularly the left ventricle. This is due to the fact that the blood leaves the left ventricle in order to be pumped round the body.

    Other alternate venous compression and relaxation, combined with the one way action of valves, provides a 'milking' effect similar to the action of the heart. Venous compression gives a lot of energy for blood flow, whereas a relaxation of the blood vessels allows blood to move towards the heart.

    The breathing system involves the inhalation of oxygen and the exhalation of carbon dioxide and water. It also includes the gaseous exchange at the alveolar-capillary surfaces whereby oxygen diffuses into the bloodstream and carbon dioxide diffuses out. As we have already established, during exercise there is an increased need for oxygen.
