Teenagers involved in group-based sports report they feel happier and healthier than those who are not, researchers at the University of West Virginia found.

Scientists discovered the findings after surveying 245 children from grades seven and eight.

“Playing on a sports team was linked to higher life satisfaction in both boys and girls. In addition, boys were five times more likely, and girls 30 times more likely, to describe their health as fair/poor when they were not playing on a sports team,” a statement about the study showed.

The study indicates that physical group activities also improve mental health.

“Our findings suggest that sports team participation may enhance school connectedness, social support and bonding among friends and teammates,” the study’s authors said (ibid.).

Involvement in physical activity is an essential part of developing healthy bodies—especially during the teenage years. Exercise strengthens the heart and lungs, and increases bone and muscle mass.
