Basic Exercise Science - Endocrine System
Primary endocrine glands
The "Master Gland" .....
.... it controls the functions of the other endocrine glands.
Primary energy source during vigorous exercise
Helps regulate energy and glucose metabolism in the body
opposite effect to that of insulin.... it raise blood glucose levels by triggering the release of glycogen stores from the liver
Epinephrine (adrenaline) and norepinephrine - hormones produced by the adrenal glands. Part of fight or flight response
- increases heart rate and sroke volume
- elevates blood glucose levels
- redistributes blood to working tissues
- opens up the airways
Testosterone and Estrogen
Testosterone male hormone (10 times more in men that women).... plays
a role in growth and repair of tissue. Raised levels of testosterone
are indicative of an anabolic (tissue building) training status.
Estrogen has influence on fat deposition around the hips, buttocks and thighs
Typically referred to as a catabolic hormone (associated with tissue
Overtraining, excessive stress, poor sleep, and bad nutrition can lead to raised levels of cortison. High levels of cortison can lead to significant breakdown of muscle tissue along with other potentially harmful side effects
released from pituitary gland and regulated by hypothalamus.
Releases vital homones that are primarily responsibe for human metabolism.
