  Background: Activities generating relatively high ground-reaction forces produce greater gains in bone mass than low- to moderate-intensity forces, especially when imposed during early childhood. We investigated in a pediatric population the amount of time spent in Vigorous Physical Activity (VPA), that is currently used to estimate high-intensity forces beneficial to skeletal health. The objectives of this study were: 1) to quantify the proportion in a general pediatric population that do not accumulate at least 20 minutes of VPA daily, which is currently recommended for bone health; 2) and to identify any age and gender-based differences. Methods: Physical activity wasrecorded during 10 days using an uniaxial accelerometer in 255 children and adolescents (117 females; 138 males). According to Ekelund et al.,VPA was defined as > 3000 count.. View More»
