The Aerobic Training and Fitness

Many people take the term “fitness” as something which refers to a sports branch which combines the aerobic training sessions with the ones meant to develop your strength. However, for scientists, it represents the level at which the cardiovascular system works. The measure of the fitness would be the general endurance, which is also known as the working capacity you get over longer periods of time. More generally, the term “fitness” could be referring to the optimum performance of your body and to its well-being.Aerobics is the maximum capacity of taking over, of transporting and of using the oxygen you get. This very important index you can verify in laboratories gives us the best appreciation of the cardiovascular reserves and of the physical fitness. This capacity varies depending on gender, age, heredity, training level and health condition.

Here are a few positive effects of an aerobic training. First of all, it increases the efficiency of the respiratory process and the resistance to effort of the muscles which are responsible with your breathing. Then, it increases the volume of blood, its distribution ad its transportation to the muscles. Also, it levels different nervous and hormonal mechanisms. Last but not least, it increases you cardiovascular efficiency. This means that your heart becomes more efficient, pumping much more blood with every beat, which doesn’t happen with the untrained people, whose pulse levels increase. In other words, their heart needs to beat faster in order to send the blood and the oxygen to the other organs.

If you want to know about the specificity of the training sessions, yo should know that a particular physical activity, like jogging, only involves those muscular fibres which are suited to that kind of effort. The fibres which contract very slowly are the ones involved in this case. Also, each physical activity involves only those metabolic ways and energetic sources which you need in order to be able to do that activity. Using the same mechanism over and over again, it adapts and this adaptation effect is what we call the training effect.
