20 Minutes of Vigorous Physical Activity Daily Advised for Teens

The following is excerpted from an online article posted by HealthDay.

Twenty minutes of daily vigorous physical activity (VPA) seems to be best for maximizing cardiorespiratory fitness (CRF) in adolescents, according to a study published online in Pediatrics.

Noting that there is no clear guidance on the intensity and duration of VPA that adolescents require to maximize CRF, Samuel Joseph Burden, from the John Radcliffe Hospital in Oxford, England, and colleagues examined the strength of association between each VPA intensity and CRF. VPA was assessed by wrist-worn accelerometers, and CRF was assessed with 20-m shuttle runs among 339 adolescents aged 13 to 14 years.

The researchers found that up to about 20 minutes of daily VPA, greater VPA was associated with better CRF, at which point the association plateaued.
