Endorphin production can be triggered by vigorous aerobic exercise. The release of β-endorphin has been postulated to contribute to the phenomenon known as "runner's high". [40] [41] However, several studies have supported the hypothesis that the runner's high is due to the release of endocannabinoids rather than that of endorphins. [42]
In acute assessment of hormone levels in soccer players before, during and after a game, DHT and testosterone increased during the match, but returned to baseline after 45 minutes rest. [14] Aerobic exercise in Japanese rats done on a rodent treadmill doubled local concentrations of DHT in calf muscles as assessed by protein assay. [15]
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 ...
Pleasure hormone dopamine is a key cause of improved reaction times following exercise, according to new research. Scientists at the University of Portsmouth say the findings could lead to new ...
They explained that the brain benefits of exercise could be due to an increase in blood flow to the brain after exercise and stimulate the release of hormones like dopamine that have a range of ...
The stress induced during exercise results in an increase in the hormones, epinephrine and norepinephrine, which are known for the body's "fight or flight" response. Increased secretion of catecholamines are a hormone response regulated by the sympathoadrenal system (SAS) and the hypothalamic-pituitary-adrenal axis (HPAA). [10]
Studies have demonstrated that serum concentrations of endogenous opioids, in particular β-endorphin and β-lipotropin, increase in response to both acute exercise and training. [21] The release of β-endorphin during exercise is associated with a phenomenon colloquially known in popular culture as a runner's high. [22]
Local hormones are activated and inactivated quickly. [1] They are released during physical work and exercise. They mainly control smooth and vascular muscle dilation. [2] Strength of response is dependent upon the concentration of receptors of target cell and the amount of ligand ( the specific local hormone). [3]
