Study Notes

Neuroendocrine System and Exercise: Key Points

Concurrent exercise training shows attenuated strength increases compared to resistance training alone, but aerobic improvements are only slightly attenuated compared to endurance training alone
PGC-1a stimulation results in increased mitochondria and mTORC stimulation results in strength increase
Detraining retains strength adaptations and may lead to loss of muscle size within activity Type 2 fibers
Resistance training decreases LDL-C, SBP, DBP, raises HDL-C, and has positive effects on metabolic syndrome/risk factors
Neuroendocrine system involves neurotransmitters, hormones, nervous system, and pituitary gland
Sympathetic nervous system increases heart rate and respiratory function, stimulates adrenal medulla, and enhances clot formation
Energy production during exercise involves lipolysis and glycogenolysis
Endocrine response to exercise involves hormone levels, receptors, and plasma levels
Exercise plays a key role in fuel mobilization, blood flow control, and remodeling through hormones like testosterone, GH, and IGF
Adipocytes release adipokines, leptin, and catecholamines, affecting fuel mobilization and appetite
Exercise leads to decreased hormone levels (except insulin) and increased sensitivity to insulin, with changes in cardiovascular, muscle, and bone growth from growth hormone
The endocrine system and training show attenuated metabolic responses, decrease in hormone levels (except insulin), and increased sensitivity to insulin, with decreased leptin levels.
