Protecting the brain from even minor disruption is important since exercise depends upon motor control. Because humans are bipeds, motor control is needed for keeping balance. For this reason, brain energy consumption is increased during intense physical exercise due to the demands in the motor cognition needed to control the body. [34]
Bones and muscles work together to support daily movements. Physical activity strengthens muscles. Bones adapt by building more cells, and as a result, both become stronger. Strong bones and muscles protect against injury and improve balance and coordination. In addition, active adults experience less joint stiffness and improved flexibility ...
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 ...
Researchers have found that the same nerves that signal muscles to move can also stimulate brain-boosting molecules. Exercise stimulates brain function thanks to its effect on muscles, study ...
The noted ancient Greek physician Galen (131–201) wrote 87 detailed essays about improving health (proper nutrition), aerobic fitness, and strengthening muscles. [2] [3] Galen. New ideas upon the working and functioning of the human body emerged during the Renaissance as anatomists and physicians challenged the previously known theories. [4]
Physical activity is defined as any voluntary bodily movement produced by skeletal muscles that requires energy expenditure. [1] Physical activity encompasses all activities, at any intensity, performed during any time of day or night. [2] It includes both voluntary exercise and incidental activity integrated into the daily routine. [3]
Men and women have similar reactions to resistance training with comparable effect sizes for hypertrophy and lower body strength, although some studies have found that women experience a greater relative increase in upper-body strength. Because of their greater starting strength and muscle mass, absolute gains are higher in men. [96]
