Abstract: Purpose: This analysis is intended to seek individualized secondary weight control methods in consideration of the periodic training requirements of He Kexin. The combination of controlled diet with different training methods is adopted so as to keep her weight at a relatively stable level or lower her weight growth speed throughout the winter training period, and at the same time improve her physical fitness in response to specific gymnastic requirements. Method: He Kexin’s weight control during winter training is divided into three periods. Period I: Providing specialized training plus aerobic training offering maximal fat oxidation and intensive strength training. Period II: Training dominated by local strength endurance circuit training. Period III: Training on capsule exercise treadmill is applied to further lower body fat percentage and control quick growth of muscles. The athlete had been on controlled diet throughout the three periods. Result: Through diet control and aerobic training in Period I, He Kexin’s body weight, body fat rate and fat weight were reduced to some extent. In Period II, the athlete’s weight and core strength saw certain growth after the Spring Festival holidays, and the weight increase was mainly attributed to strength training and uncontrolled diet in addition to natural growth as result of the athlete’s body development. In Period III, the athlete’s total muscle and fat mass had saw some decrease but her core strength was still higher than the level before the intervention. Conclusion: The intervention method of controlled diet plus individualized aerobic training and strength training can play some secondary role in controlling the weight of gymnastic athletes during the growth period. Gymnastic athletes during such period should, while paying attention to weight control, also strengthen the training of the weak parts of their bodies in order to ensure greater improvement of their physical qualities than their weight increase. The body composition and muscle strength level of female gymnastic athletes during the growth period are of great significance to training practice, so the corresponding testing and evaluation system should be further studied and improved.
