All students began their studies on the same level in the mental health assessments.
Exercisers in groups noticed improvement in all three areas of their lives over the course of twelve months. They also noticed an improvement in their stress levels.
In comparison to individuals who exercised in a group, the solo exercisers only saw a slight improvement in the quality of their mental lives despite working for less than an hour every week.
The group that was in control did not notice any change in their stress levels or the quality of life at the conclusion of the study.
There are certain limitations to the study, for instance its size being small and the it's inclusion of medical students only.
