    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.
