Exercise is "Physical activity which is usually regular and done with the intention of improving or maintaining physical fitness or health."[1]
Types of physical activities
Usual daily activities
"Neighborhood physical and social environmental factors are significantly associated with walking at recommended levels."[2]
Moderate to high intensity exercise
(in progress)
Effects of exercise
Effect on insulin sensitivity
(in progress)
Effect on insulin production
Aerobic exercise was shown to increase beta cell function in older persons, in whom both insulin production and insulin sensitivity are frequently impaired.[3]
Effects on the brain
The effects of exercise on mood and mental functioning, described by the latin quotation Mens sana in corpore sano (a healthy mind in a healthy body), are profound. Research attempting to isolate the biochemical nature of this relationship showed that the access to the brain of the insulin-like growth factor I, which is stimulated by physical activity, could explain much of the beneficial effects of exercise.[4]
