This study examined the independent and additive effects of two interventions (milk supplementation and resistance training) on nutrient adequacy, body composition, and bone health in adolescent girls. Sixty‐six adolescent girls (13 – 17 y) were placed into one of four groups: Milk only [M, n = 20]; Resistance training only [RT, n = 15]; Milk + resistance training [MRT, n = 15]; or Control [CON, n = 16]. Girls in the milk groups were provided 3 servings of milk/d for 12 wk. Girls in the training groups performed a supervised, progressive resistance training program for 12 wk. Compliance to the training and milk supplementation was exceptional (>97%). Mean calcium intake was 758 and 1581 mg/d, in the non‐milk and milk groups, respectively. Resistance training had a main effect on body mass, lean body mass, muscle strength, and muscle endurance. There was a main effect of milk and resistance training on several measures of bone mineral density (BMD) with the effects being additive. Changes in whole body BMD in the M, RT, MRT, and CON were 0.45, 0.52, 1.32, and −0.19%, respectively (P<0.01). In summary, improving nutrient status with milk supplementation or resistance training were both equally effective at improving BMD in adolescent girls. The additive nature of milk and resistance training on BMD highlights the need to combine interventions that utilize different mechanisms to optimize bone health.
