The participants were divided into four groups: one that did not engage in physical activity; a second that did 75 to 150 minutes of physical activity a week; a third that did 150 to 240 minutes a week; and a fourth that did more than 240 minutes a week.
Depression and burnout rates were clearly the highest among the group that did not participate in physical activity. The more physical activity that participants engaged in, the less likely they were to experience elevated depression and burnout levels during the next three years. The optimal amount of physical activity was a minimum of 150 minutes per week, where its benefits really started to take effect.
In those who engaged in 240 minutes of physical activity or more, the impact of burnout and depression was almost nonexistent. But even 150 minutes a week will have a highly positive impact, says Dr. Toker, helping people to deal with their workday, improving self-efficacy and self-esteem, and staving off the spiral of loss.
