Chapter 3 - Endocrine responses to Resistance Exercise Flashcards
Growth hormone
stimulates IGF-1, protein synthesis and metabolism.
Adrenocorticotropic hormone
Stimulates glucocorticoids in the adrenal cortex
Analgesia
Loss of sense of pain
Beta endorphin
Stimulates analgesic response
Follicle stimulating hormone
Stimluates ovum and sperm production
Luteinizing Hormone
Stimulates ovulation and secretion of sex hormones in ovaries and testes
Prolactin
Stimulates milk production in mammary glands and maintains secretion of progesterone.
Melanocyte stimulating hormone
Stim. Melanocytes that have dark melanin
Anti diuretic hormone
Increased smooth muscle contraction and reabsorption of water by the kidneys.
Oxytocin
Stim uterine contractions andrelease of milk by mamm glands
Thyroxine
Stimulates oxidative metabolism in mitochondria and cell growth
Calcitonin
Reduces calcium phosphate levels in blood
Parathyroid hormone
Increase blood calcium, decrease blood phosphate, stimulates bone formation
Insulin
Stores glycogen, promotes glucose entry into cells, involved in protein syntheses
Glucagon
Increases blood glucose levels
Glucocorticoids (cortisol, cortisone)
Inhibit amino acid incorporation into proteins, stimulate breakdown of protein to carbs. promote use of fat
Mineralocorticoids
Increase body fluids via sodium potassium metabolism
Insulin like growth factors
Increase protein synthesis in cells
Epinephrine
Increases cardiac output, increases blood sugar and glycogen breakdown and fat metabolism.
Norepinephrine
Like epinephrine
Proenkephalin fragments
Enhance immune cell function, analgesia effects
Estrogens
Female sex characteristics
Progesterone
Female sex characteristics and mammary glands
Testosterone
Stimulates growth, increases protein anabolism, development of male sex characteristics.
Atrial peptide
Regulates sodium, potassium and fluid volume
Renin
Regulates kidney function,permeability and solute concentrations.
testosterone is an example of a __________ hormone.
steroid
insulin is an example of a ___________ hormone.
polypeptide

testosterone
heart hormone (1)
atrial peptide
kidney hormone (1)
Renin
factors that can increase serum testosterone levels in young men (5)
short rests moderate to high volume two or more years of experience heavy resistance (85-90%) large muscle group exercises
diurnal variations are:
normal fluctuations in hormones throughout the day.
another name for growth hormone
somatotropin
in order to elicit more GH, _________ rest times and ________ intensities must be used.
short; high
IGF-1 synthesis takes about ________ hours
8-29

GH
Coritsol
IGF-1
progesterone
Gh and IGF-1
all of the following are functions of GH except

testosterone
which of the following hormone levels is higher in women at rest?
cortisol
insulin
testosterone
GH
growth hormone
