The volunteers in the study used exercise bikes that allowed the researchers to control their level of exertion so that low-intensity exercise was defined as 40 percent of their peak oxygen consumption and moderate-intensity exercise was defined as 75 percent of peak oxygen consumption. A student who stays up late to finish a term paper may feel fatigued, for example, but may also feel energized as she nears the end of the paper. He adds that energy and fatigue aren’t exactly opposites of each other. “It could be that moderate-intensity exercise is too much for people who are already fatigued,” O’Connor said, “and that might contribute to them not getting as great an improvement as they would had they done the low-intensity exercise.” Surprisingly, the low-intensity group had a greater reduction in fatigue levels than the moderate-intensity group, 65 percent compared to 49 percent, respectively. The low- and moderate-intensity groups had a 20 percent increase in energy levels over the control group. ![]() The volunteers were divided into three groups: The first engaged in 20 minutes of moderate-intensity aerobic exercise three times a week for six weeks the second engaged in low-intensity aerobic exercise for the same time period the control group did not exercise. The researchers recruited 36 volunteers who did not exercise regularly and had reported persistent fatigue based on a commonly used health survey. There’s a scientific basis for it, and there are advantages to it compared to things like caffeine and energy drinks.” “Exercise is a way for people to feel more energetic. “A lot of people are overworked and not sleeping enough,” O’Connor said. O’Connor said about 25 percent of the general population experiences such fatigue. In this latest study, the researchers studied volunteers who had fatigue that was persistent yet didn’t meet the criteria for a medical condition such as chronic fatigue syndrome. Those studies, however, primarily looked at patients with medical conditions such as cancer, heart disease and mental health problems. O’Connor said previous studies – including one that he and Puetz co-authored in 2006 – have shown that exercise can significantly improve energy levels and decrease fatigue. The team’s results appear in the February issue of the journal Psychotherapy and Psychosomatics. Puetz co-authored the study with professor Patrick O’Connor, co-director of the UGA Exercise Psychology Laboratory, and former UGA student Sara Flowers. “However, we have shown that regular exercise can actually go a long way in increasing feelings of energy – particularly in sedentary individuals.” ![]() “Too often we believe that a quick workout will leave us worn out – especially when we are already feeling fatigued,” said researcher Tim Puetz, who recently completed his doctorate at UGA and is the lead author of the study. ![]() – Sedentary people who regularly complain of fatigue can increase their energy levels by 20 percent and decrease their fatigue by 65 percent by engaging in regular, low intensity exercise, according to a new University of Georgia study. ![]()
