183
function of the portal vessels from the hypothalamus to the pituitary gland
carry the trophic hormones directly to the anterior pituitary
184
What are the acute effects of endurance training on the anterior pituitary
1. Endorphins: Increases with long duration exercise
2. Prolactin: increases with intensity
3. Somatotropin: increases with moderate intensity
185

1. Aldosterone: increases with intensity
| 2. Cortisol: Increases 60-90% of VO2max; Increase: Intensity / duration
187
what are the acute effects of endurance training on the adrenal medulla
1. Norepinephrine: Increases 50-60% of Vo2max: Increase: Intensity
2. Epinephrine: Parallel to norepinephrine, but less
188
what are the acute effects of endurance training on the thyroid
1. Triiodothyronine (T3): Increases with intensity
| 2. Thyroxine (T4): Increase with intensity
189
what are the acute effects of endurance training on the pancreas
1. Glucagon: 1-2 hours after onset of exercise
| 2. Insulin: Decrease 50% of VO2max
190
what are the acute effects of endurance on the parathyroid
parathormone increases with long duration exercise
191
what are the acute effects of endurance on the ovaries
1. estrogen: increases with exercise
| 2. progesterone: increases with exercise
192
acute effects of endurance training on the testes
testosterone increases with exercise
193
acute effects of endurance training on the kindeys
renin increases with intensity
194
function of the parathormone
stimulates osteoclasts to release Ca into blood stream
195
what is synthesized in the testes which produces estrogen
aromatase
196
what are the estrogen levels in men and women
Women: 5-7ng/dl
Men: 2-5ng/dl
197
what are the testosterone levels in men and women

198
Chronic effects of endurance training on Hypothalamus-Pituitary Hormones
1. ACTH: Increases
2. Endorphin: Decreases
3. FS / LH: Decreases
4. Estrogen: Decreases
5. Testosterone: Decreases; Resist. Trained males – Increases
6. Somatotropin: No change – rest; Decreased - exercise
199
what are the chronic effects of endurance training on the thyroid hormones
Triiodothyronine (T3): Decreases; Increased turnover
| Thyroxine (T4): Decreases; Increased turnover
200
what are the chronic effects of endurance training on the adrenal hormones

why type of exercise can aid the immune system by not elevating stress hormones
moderate exercise (3-4 METS)
203
what are the effects of chronic physical activity on platelet aggregability
1. associated with early/advanced atherosclerosis
2. heavy exercise transiently increases blood coagulation
3. moderate exercise activates fibrinolysis
204
effects of chronic physical activity on adipose tissue
1. increase in mobilization of fat stores
2. upper body fat is easier to mobilize
3. gluteal adipose cell liplysis to catecholamines is acutely increased following endurance exercise in men
