Summary

The investigators primary objective is to evaluate the effect of a 6 month (3 days/wk) supervised, progressive RT program with increased daily milk intake in untrained adolescents on measures of body composition and cardiovascular risk factors. The investigators hypothesize that milk supplementation will produce significantly greater favorable changes in all body composition measures compared with RT + carbohydrate and control.

Detailed description

We will recruit 150 healthy, adolescent middle school boys and girls (grades 7 through 9), BMI \> 50th percentile \< 98th percentile, who will participate in 6 months of supervised resistance training (3 days/wk) and will be randomized to one of 3 groups: RT + milk, RT + isocaloric carbohydrate, RT only (control). Both physical activity and diet outside the study protocol will be carefully monitored. Measurements will be completed at baseline 3 months and upon completion of the training protocol at 6 months.

Conditions

• Body Composition
• Cardiovascular Risk Factors

Interventions

Type	Name	Description
OTHER	Resistance Training with Milk Supplementation in Adolescents	On resistance training days, the RT+ milk group will receive milk (280kcals) immediately following exercise and milk at another time during the day. The RT+ juice group will receive fruit juice immediately following resistance exercise and juice again another time during the day. The RT+ water group will receive water following resistance exercise and water at another time during the day. On non training days, students in the RT+ milk group will receive milk. Students in the RT+ juice group will receive juice. The RT+ water group will receive water during the school day. On non-RT days, the total volume of milk, juice, or water will be split into two administration times during the school day.
