Two new studies reveal that males are more physically active than females.
According to the research, the activity difference is lifelong.
A study focusing on primary schools in Liverpool, England finds girls participate in six percent less vigorous activity than boys do on the playground.
One of the authors of the study that are part of a National Prevention Research Initiative says girls and boys play differently.
Dr. Nicky Rodgers says girls are more likely to play in smaller groups and in verbal games, such as socializing.
Boys tend to participate in larger play groups, which generally result in more physically active games, such as football.
The findings of the research did not reveal the impact of playtime activity on children's weight, but experts believe there is a link.
Studies show adult females are more likely to be clinically obese than men.
The results of the study pertaining to schoolchildren is also reflected in people over the age of 70.
So far, men in that age range are found to be much more physically active than women.
