It is good to play outdoor games and participate in sport, but in order to reduce risks of obesity or becoming overweight, a teenager needs to be active enough to play more than one sport, says a team of researchers from Dartmouth College.

Recently published in the journal Pediatrics, the study conducted by the team shows that children in their teens playing more than one sports were more benefitted than their fellows playing just a single game.

The review was carried out with an enrolment of some 1,718 Vermont and New Hampshire high-schoolers. Questioning them about their physical education, and time spent on fun activities, the team found that those playing atleast two games were almost 26% less prone to becoming obese or overweight.

The participants were also asked if and how much they used to participate in sports and how much time was spent on TV or computer along with their habit to ride a bike to school. All the data led to a conclusion that more sports was ultimately leading to more reduction in risks of obesity.

It has been told that even three sports by a teen helps him to cut some 27% risk of being overweight, while chances of being obese was cut by 39%.
