Exercise increases energy levels
​​
-
Feelings of low energy and fatigue are a major public health problem. Although less than 1% of the population suffers from chronic fatigue syndrome, persistent fatigue is reported by about 20% of adults in community samples (Wessely, Hotopf, & Sharp, 1998).
​
-
Population-based studies show that physical inactivity is consistently associated with fatigue (Puetz, 2006).
​
-
Exercise has been associated with improving energy levels in many studies.
​
-
Researchers analyzed 70 studies on exercise and fatigue In a study published in Psychological Bulletin in 2006. These studies involved over 6800 people.
​
-
More than 90% of the studies showed that sedentary people who completed a regular exercise program reported improved fatigue compared to groups that did not exercise (Puetz, O'Connor, & Dishman, 2006).
