How Does the Body Adapt to Exercise?
How does the body adapt to exercise?
The body is an incredible working machine that can adapt to the stress that is placed upon it. The process of adaptation due to stress is known as the General Adaptation Syndrome (GAS). The first stage is called the alarm stage, where the body first reacts to stress, humans exhibit a "fight or flight" response, which prepares the body for physical activity. The next stage is called the resistance stage, where the body attempts to adapt in order to cope with the stress. Lastly, if the stress persists the body’s resources are depleted and the body enters the exhaustion phase.
When a stress (exercise) causes the body to increase effort more than it is normally accustomed to, the body has been put into a situation of overload. Overload will temporarily decrease the body’s ability to do work ( work capacity). After the body has had enough time to recover from the original stress of exercise, its work capacity increases to a level greater than the original.
