The findings were published online December 12 in JAMA Psychiatry.

The researchers found that increases in physical activity tended to be followed by increases in mood and perceived energy level. This beneficial effect was even more pronounced for a subset of the study subjects who had bipolar disorder. For the study, activity trackers and electronic diaries were used for two weeks in a community sample of 242 (150 women and 92 men) adults, ages 15 to 84, with an average age of 48 years. The sample included 54 people with bipolar disorder.

Assessments - Study - Devices - Levels - Movement

Mobile assessments in the study included wrist-worn devices that automatically recorded levels of physical movement in real time and electronic diaries that assessed mood and perceived energy levels four times per day for two weeks. These real-time mood and energy levels were rated by study participants on a seven-point analogue scale from "very happy" to "very sad" for mood and from "very tired" to "very energetic" for energy.

"Systems regulating sleep, motor activity and mood have typically been studied independently. This work demonstrates the importance of examining these systems jointly rather than in isolation," says Vadim Zipunnikov, PhD, an assistant professor in the Bloomberg School's Department of Biostatistics, who led the data analyses.

Findings - Average - Activity - Level - Time-point

The findings showed that on average a higher activity level at one time-point was associated with improved mood and increased perceived energy at the next time-point during the day. (The daily time-points were personalized according to the person's daily schedule, with...
