	abstract = {BACKGROUND: Physical activity is necessary for bone mass 
		development in adolescence. There are few studies quantifying 
		the associations between physical activity and bone mass in 
		adolescents. PURPOSE: To assess the relationship between 
		moderate-to-vigorous physical activity (MVPA) and vigorous 
		physical activity (VPA) and bone mass in adolescents. METHODS: 
		Bone mass was measured by dual-energy X-ray absorptiometry and 
		physical activity by accelerometers in 380 healthy Spanish 
		adolescents (189 boys, aged 12.5-17.5 years) from the HELENA-CSS 
		(2006-2007). Subjects were classified according to the 
		recommended amount of MVPA (<60 minutes or >/=60 minutes of 
		MVPA/day). Receiver operating characteristic curve analysis was 
		applied to calculate the relationship between physical activity 
		and bone mass. RESULTS: Less than 41 and 45 minutes of MVPA/day 
		are associated with reduced bone mass at the trochanter and 
		femoral neck. More than 78 minutes of MVPA/day is associated 
		with increased bone mineral density (BMD) at the femoral neck. 
		Regarding VPA, more than 28 minutes/day for the hip and 
		intertrochanter and more than 32 minutes/day for the femoral 
		neck are associated with increased BMD. CONCLUSIONS: The 
		recommended amount of physical activity (minutes/day) seems 
		insufficient to guarantee increased bone mass. With some minutes 
		of VPA/day, bone adaptations could be obtained at different bone 
		sites.},
