The Importance of Cardiovascular Conditioning - 3006 Words

Cardiovascular fitness shows how the heart and lungs supply oxygen-rich blood to the working muscle tissues and the ability of the muscles to use oxygen to produce energy for movement. The ability to deliver oxygen to the muscles is affected by many physiological parameters, including heart rate, stroke volume, cardiac output, and maximal oxygen consumption. Cardiovascular conditioning utilizes and transports the necessary oxygen and nutrients to body tissues. In order for the body to deliver adequate oxygenated blood and nutrients to the muscles, the body has to be well conditioned. By the body being well conditioned it improves the muscles capacity to use extra oxygen. Cardiovascular training is the most important style of training both†¦show more content†¦The warm up is the most important part of cardiovascular conditioning. Warming up before an intense exercise helps to gradually increase the heart rate and prevent abnormal heart rhythms. Warming up also helps with prev enting straining on the heart muscle and heart attacks from abnormal heart rhythms. The warm up period should last about five to ten minutes. During this time the body is preparing for the exercise activities. Warm up exercises prepare the body for exercising by increasing the blood flow to the muscles allowing them to loosen up, which can raise the flow of oxygen to the muscle cells. Doing this gradually increases the bodys temperature. This then increases the speed and force of muscular contractions, because nerve impulses travel faster at higher body temperatures, and muscles become less stiff or more pliable. They also help to gradually increase the heart rate and ensure that the demand made on the circulatory and metabolic systems is gradual as well. In a safe and gradual way they allow blood to be diverted away from other parts of the body such as the digestive system to the muscles being exercised. This initial part of your exercise session helps to improve neural function and co-ordination, protect major joints as it takes time to increase the supply of lubricating synovial fluid and to thicken the articular cartilages – the body’s shock absorbers. The warm ups intensity should cause perspiration but not cause fatigue. The typeShow MoreRelatedObesity Is Popular Modern Society1579 Words   |  7 Pagesobesity and chronic illness.
