Ch 4: Endocrine system Flashcards
Hormones secreted from the anterior pituitary
Growth Hormone
Beta-endorphin
Prolactin
LH
FSH
TSH
Adrenocortocotropic
Posterior Pituitary Hormones
ADH
Oxytocin
Adrenal Cortex Hormones
Mineralcorticoids
Glucocorticoids
Adrenal Medulla Hormones
Norepinephrine
Epineprhine
What are the anabolic hormones?
IGF, GH, Testosterone
Where is IGF secreted from?
The liver
The role of GH
Decrease glucose utilization and synthesis
Increase AA transport, protein synthesis, fatty acid utilization, collagen synthesis, cartilage growth
When is GH concentration the highest?
At sleep
Best stimulus for GH?
High intensity RT with short rest with 3 sets of every exercise
Testosterone functions
Key to stimulating anabolic functions and needed for GH response
Best stimulus for testosterone?
Large muscle group exercises at 85-95% resistance at moderate-high volume at short rest of 30 sec - 1 min
Cortisol function
Increase level of proteolytic enzymes.
Converts AA to carbs and inhibits protein synthesis
Best stimulus for cortisol?
Short rest and total volume high
Cataecholemines function
Increase force production, muscle contraction, BP, cardiac output, energy availability, muscle blood flow
Augument secretion of testosterone
Best stimulus for catecholemines
High intensity, short rest, heavy RT
Steroid hormones
Lipophilic, hydrophobic
Adrenal cortex and medulla hormones
Need cholesterol
Polypeptide/Protein Hormones
Lipophobic, hydrophilic
Insulin and GH
Amine Hormones
Epinephrine, norepinephrine
What does an increase in hormone concentrations indicate?
More interaction
