Background Osteoporosis is a major worldwide health concern. The acquisition of bone
mass during growth decreases the risk of osteoporosis later in life. Muscular strength is an …

We examined the effects of a 7month jumping intervention (10 minutes, 3 times per week)
on bone mineral gain in prepubertal Asian and white boys (10.3±0.6 years, 36.0±9.2 kg) at …

Purpose To assess association between lower body muscle power and bone strength, as
well as the mediating effect of muscle cross-sectional area (MCSA) on that association …

Context: The intensity of habitual physical activity (PA) needed to affect skeletal
development in childhood is currently unclear. Objective: To examine associations between …

Although positive effects of physical activity are often reported, there are still uncertainties
about the type, intensity, duration, and frequency of these activities that are most effective for …

Skeletal loading during growth may be one way of increasing bone mass early in life. We
hypothesized that children randomized to a jumping program (25 jumps/day from a 45-cm …

The purpose of this study was to assess the interactive effects of habitual physical activity
(total and vigorous intensity) and calcium intake on bone mineral content (BMC) in …

It is increasingly accepted that osteoporosis is a paediatric issue. The prepubertal human
skeleton is quite sensitive to the mechanical stimulation elicited by physical activity. To …

Osteoporotic fractures are a debilitating and a frequently fatal health problem for older
adults. A growing body of evidence indicates that osteoporosis has its origin in early life and …

Objectives. Physical activity has a beneficial effect on bone development in circumpubertal
children, although its effect on younger children is uncertain. In this cross-sectional study, we …
