Main Functions

Mechanisms

1)Resistance Training (RT) Acute Program Variables

2)Aerobic, Plyometric, Sprint, & Agility Training Variables

3)Other Variables Affecting Hormonal Responses

1) Concentration of the hormone in the plasma 2) Number of receptors available

1)Acute responses during exercise 2)Chronic changes in resting concentrations 3)Chronic changes in acute response to exercise 4)Receptor changes

Testosterone, Progesterone and Estrogen, Insulin-Like Growth Factors (IGFs), Antidiuretic Hormone (ADH,), Insulin, Glucagon, Cortisol, Aldosteron, Formation Renin
