  2. Neurobiological effects of physical exercise - Wikipedia

    en.wikipedia.org/wiki/Neurobiological_effects_of...

    Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...

  3. Muscle hypertrophy - Wikipedia

    en.wikipedia.org/wiki/Muscle_hypertrophy

    As muscle hypertrophy is a response to strenuous anaerobic activity, ordinary everyday activity would become strenuous in diseases that result in premature muscle fatigue (neural or metabolic), or disrupt the excitation-contraction coupling in muscle, or cause repetitive or sustained involuntary muscle contractions (fasciculations, myotonia, or ...

    en.wikipedia.org/wiki/Growth_hormone_in_sports

    It should be clarified, though, that muscle mass is not the same as muscle strength. Some say that human growth hormone will build muscle mass through raised insulin-like growth factors levels leading to heightened protein synthesis without any side effects [12] while other researchers argue that there have been no such findings on young ...

    The effects are widespread and can affect anything from muscle growth to aerobic stamina to diabetes and other metabolic disorders. [35] In general, even a small amount of exercise can induce hypomethylation of the whole genome within muscle cells. This means that many regulatory genes can be turned on for pathways like muscle repair and growth.

  6. Myokine - Wikipedia

    en.wikipedia.org/wiki/Myokine

    One explanation for the increased irisin expression with exercise in mouse and man may have evolved as a consequence of muscle contraction during shivering. Muscle secretion of a hormone that activates adipose thermogenesis during this process might provide a broader, more robust defense against hypothermia.

  7. Growth hormone therapy - Wikipedia

    en.wikipedia.org/wiki/Growth_hormone_therapy

    Growth hormone is a peptide hormone secreted by the pituitary gland that stimulates growth and cell reproduction. In the past, growth hormone was extracted from human pituitary glands. Growth hormone is now produced by recombinant DNA technology and is prescribed for a variety of reasons. GH therapy has been a focus of social and ethical ...

    Those noticeable physical changes from exercise (be it muscle growth, fat loss, or a lower resting heart rate) depends on the person and their baseline level of fitness.

  9. Growth hormone - Wikipedia

    en.wikipedia.org/wiki/Growth_hormone

    Growth hormone (GH) or somatotropin, also known as human growth hormone (hGH or HGH) in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development.
