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 ...
The exercise paradox, [1] also known as the workout paradox, [2] refers to the finding that physical activity, while essential for maintaining overall health, does not necessarily lead to significant weight loss or increased calorie expenditure. [3]
Intense prolonged exercise produces metabolic waste heat, and this is removed by sweat-based thermoregulation. A male marathon runner loses each hour around 0.83 L in cool weather and 1.2 L in warm (losses in females are about 68 to 73% lower). [22] People doing heavy exercise may lose two and half times as much fluid in sweat as urine. [23]
Studies have found that physical exercise is a viable, non-pharmaceutical approach to resisting and even undoing the harmful processes that cause sudden abnormal changes in brain cell activity resulting in seizures that characterize epilepsy. [55]
In the philosophy of mind, mind–body dualism denotes either that mental phenomena are non-physical, [1] or that the mind and body are distinct and separable. [2] Thus, it encompasses a set of views about the relationship between mind and matter, as well as between subject and object, and is contrasted with other positions, such as physicalism and enactivism, in the mind–body problem.
Physical fitness is achieved through exercise, among other factors.Photo shows Rich Froning Jr., four-time winner of "Fittest Man on Earth" title.. Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations, and daily activities.
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]
There are two general ways to describe this event: in terms of mental events (where the conscious sensation of pain caused one to say 'ouch') and in terms of physical events (where neural firings in one's toe, carried to the brain, are what caused one to say 'ouch'). The main task of the mind–body problem is figuring out how these mental ...
