Physical training is one of the best things you can do to ensure both your long- and short-term health. The benefits of exercise may seem distant when you go for that first run or lift your first weight, but both the short- and long-term benefits of exercise can help motivate you to keep at a physical fitness routine.
A hard training session utilizes glycogen to give you energy. When your glycogen stores become depleted, the body releases hormones called endorphins that can cause feelings of elation and well-being. The effects are immediate and short-term, but physical training also offers long-term benefits. Regular exercise can help prevent depression and may alleviate symptoms when depression occurs. A study published in the "Archives of Internal Medicine," for example, found that regular exercise was as effective at treating depression as popular antidepressants.
During exercise, your heart rate must increase to supply your muscles with oxygen-carrying blood. This may cause you to feel winded and dizzy, but it also increases circulation on a short-term basis. After a few months of exercise, your pulse may drop and your blood pressure may decrease. Regular exercise is a significant predictor of cardiac health, and people who get cardiovascular exercise on a regular basis decrease their long-term risk of stroke, heart attack and other cardiovascular problems.
Even one exercise session can affect your muscle health by supplying additional blood and oxygen to the muscle. According to the book "Myofascial Trigger Points," this can increase healing time and alleviate pain associated with a sedentary lifestyle. On a longer term basis, exercise improves muscle health, increases muscle size and reduces the likelihood of muscular injuries such as sprains and strains.
During exercise, your rate of respiration increases so that your blood can be properly oxygenated, allowing your muscles to work well. For some people, this can cause feelings of being winded and may even result in a burning in the chest or throat that lasts a few hours or days. After longer term exercise, however, respiratory health improves. Lung capacity may increase, and your respiration may become more efficient. You'll also be able to slow your breathing more quickly after physical training and will be less likely to experience discomfort or burning during exercise.
