Purpose: The determinants of areal bone mineral density (aBMD) and hip geometry 26
estimates in adolescent athletes are poorly understood. This study aimed to identify the 27
determinants of aBMD and hip geometry estimates in adolescent male athletes. Methods: 28 …

We assessed the test–retest reliability of the Sargent jump (VJ) for vertical jumping
performed by 4 and 5 years old pre-schoolers. The VJ was administered three times
(familiarization, test, and retest) to 163 children (mean age: 4.48±0.5 years; 55.8% girls). The …

PURPOSE: Muscle cross-sectional area (MCSA) is often used as a surrogate for the forces
applied to bones during physical activity. Although MCSA is a strong predictor of cortical
bone status, its use makes assumptions about the relationship between muscle size and …

This study demonstrates that a 9-month jumping intervention can improve bone mass gains
and physical fitness performance in adolescent males participating in non-osteogenic
sports, such as swimming and cycling. Purpose To examine the effect of a jumping …

This study examined bone mineral density (BMD) accrual in prepubertal rhythmic gymnasts
entering puberty and their age-matched untrained control girls, and associations with
baseline jumping performance and body composition over the 3-year period. Whole body …

Power has long been considered to be a skill-related fitness component. However, based on
recent evidence, a strong case can be made for the classification of power as a health-
related fitness component. Additionally, the evidence indicates that performing physical …

The present study was the first one aimed to investigate the current muscle fitness and its
associated factors among children and adolescents in mainland China. From Nov 2013 to
Jul 2014, 2283 children and adolescents aged 7–18 were recruited in Hainan and Shaanxi …

Osteoporosis is one of the most common diseases experienced in the older adult
population. This condition is not only costly to manage and treat, particularly so when
osteoporotic fractures occur, but also negatively impacts functional health and health-related …

Force (F), produced by the neuromuscular system and transmitted by bones, is necessary for
locomotion. Performance in activities of daily living and sport requires effective production
and use of (F) for optimal outcomes. Quantifying neuromuscular performance, with F and …
