Increasing Fluid Milk Favorably Affects Bone Mineral Density Responses to Resistance Training in Adolescent Boys
Human Performance and Recreation
This study examined the effects of increasing milk on bone and body composition responses to resistance training in adolescents. Twenty-eight boys (13 to 17 years of age) were randomly assigned to consume, in addition to their habitual diet, 3 servings/day of 1% fluid milk (n = 14) or juice not fortified with calcium (n = 14) while engaged in a 12-week resistance-training program. For all subjects combined, there were significant (Pless than or equal to.05) changes in height (+0.5%), Sigmaseven skin folds (-7.7%), body mass (+2.6%), lean body mass (+5.1%), fat mass (-9.3%), whole-body bone mineral content (+3.6%), bone mineral density (+1.8%), and maximal strength in the squat (+43%) and bench press (+23%). Compared with juice, the milk group had a significantly greater increase in bone mineral density (0.014 vs 0.028 g/cm(2)). Increasing intake of milk in physically active adolescent boys may enhance bone health.
