Endocrine System Flashcards
Endocrine system
Facilitation of reproductive processes
Growth
Tissue maintenance and repair
Physiological dynamics that result in eustress or distress
Eustress
A positive, desirable form of stress that influences physical or physiological health.
Distress
A negative form of stress that influences physical or physiological health
Growth Hormone
Anabolic hormone- pituitary gland Promotes cell division and creation Facilitates protein synthesis Protects glycogen reserves Limits carbohydrate metabolism Release due to exercise is Intensity-dependent
Testosterone
Produced in the gonadal glands
Men have 10x more than women
High intensity total body exercises increases most effectively
Enhances size and strength of muscle
Pancreatic hormones
Production of digestive enzymes for the breakdown of food
Regulation of blood sugar by stimulating the release of insulin and glucagon
Insulin
Anabolic hormone that helps control blood sugar by driving excess glucose into muscle and the liver to be stored as glycogen, or into fat cells where it is converted into triglycerides
Glucagon
Stimulates and increase in blood sugar levels when they are low.
Specifically alpha cells in the pancreas release glucagon for transport to the liver where it stimulates the release of stored glucose into circulation
Thyroid hormones
T3/T4 Increase the metabolic rate for all cells Heavy exercise increases release Possible contributes to EPOC Increase the secretion of GH and IGF-1
Hyperthyroidism / Hypothyroidism
Will impede weight gain
Will impede weight loss
Adrenal hormones
Specifically designed to manage stress
Aldosterone
A primary regulator of electrolyte activity and water balance as it promotes re-absorption or excretion of sodium in the kidneys
Cortisol
Inhibits CHO uptake and oxidation in the body by acting as an insulin antagonist
Released during high physiological stress, leading to significant body protein breakdown
Promotes visceral fat storage in the abdomen
Catecholamines
Dopamine, norepinephrine, and epinephrine is based on the acute stress experienced in the body.
Promote heart rate and blood pressure changes
Enhance the enzymatic systems of working tissue
Promote vasodilation
Augment the release of anabolic hormones
Adaptive outcomes
Based on:
Exercise selection
Intensity and duration
Rest intervals used
