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. |
