The endocrine system also adapts to aerobic and resistance training
Adrenaline and Noradrenaline:
The gland that secretes adrenaline and noradrenaline has an increased capacity to secrete these hormones
This results in increased reaction from the organs targeted by these hormones to enable the body to be ready for exercise and sports participation at a faster rate
Cortisol:
Endurance exercise has the effect of lowering the release of cortisol in the body which helps to reduce the levels of stress a person may be suffering from
However, resistance training will actually increase resting levels of cortisol levels in the body
Testosterone:
Resistance training results in higher resting levels of testosterone and human growth hormone (HGH) which both help to increase protein synthesis for muscle hypertrophy
