CAN CHILDHOOD SPORT PREVENT ADULT OSTEOPOROSIS? - LESSONS FROM SPORT & INTERVENTION STUDIES

Abstract

2100 The symposium permits active pediatric bone researchers to present the most current results from longitudinal physical activity studies. Dr Vuori's introduction will emphasis the importance of peak bone mass as a determinant of adult bone mineral density, and thus, risk of osteoporotic fracture. Dr Bailey will summarise outcomes of the University of Saskatchewan Pediatric Bone Mineral Accrual Study, a 7-yr longitudinal study of normal children that identified the tempo & timing of peak bone mineral content velocity and examined the association between physical activity & bone mineral accrual in normally active children. Dr Haapasalo, from the Bone Research Group at the UKK Institute, will outline the strengths of the tennis model for bone research, illustrate the role of pubertal stage in modulating the effect of loading on bone accrual, and discuss results of detraining studies that suggest pediatric bone gain may provide long-standing benefits. Dr McKay will review the few pediatric intervention studies and report results of the University of British Columbia's School-based Exercise Intervention Study - a 9 month randomized control trial in a mixed ethnic group of prepubertal children - that intervened with an increased loading curriculum within existing physical education classes.
