Cardiorespiratory Fitness Vs Weight Loss

One of the studies, which has been published recently, shows that cardiorespiratory fitness significantly decreases the risk of mortality due to all causes, including cardiovascular disease. However, body weight loss by itself wasn’t related to a reduction of the risk of all cause and cardiovascular mortality.

If you lose your cardiovascular fitness, the risk of mortality due to all causes will be higher. Even if you have a good body mass index (BMI), it is better to improve and maintain your cardiorespiratory fitness because it can lower the risk of stroke, type 2 diabetes mellitus, ischaemic heart disease, lung cancer, and other diseases.

It is recommended to do aerobic exercise for 20-60 minutes a day; three to five days per week and keep up your heart rate between 65 % and 90 % of your maximum heart rate during the exercise session. Regular exercise causes healthy enlargement of the heart, increasing the pumping activity. It improves the blood supply to muscles by increasing the number of small blood vessels. Exercise gradually enhances the respiratory functions and oxygen supply to peripheral tissues too.
