This study was conducted to investigate the effects of resistance, detraining and retraining on body composition, basic physical fitness and muscular strength restoration. The subjects were 25 healthy young male university students of 20 year-old. They performed muscular progressive resistance training for 12 weeks, detraining for 8 weeks and retraining for 12 weeks. Young males conducted a resistance training program for 90 minutes a day, 4 days per week. Data analyzing method was One-way repeated ANOVA(contrast) using PASW(ver 15.0 SPSS). The effects on body composition and physical fitness test and maximal muscular strength were measured each period. In the %fat, 12 weeks resistance training appeared significantly lower than that of retraining. In the physical fitness test, back strength and grip strength(R) of resistance retraining appeared significantly higher than that of pre- and detraining. And grip strength(L) of resistance retraining appeared significantly higher than that of detraining and detraining appeared significantly higher than that of pre-. Sit and reach of retraining appeared significantly higher than that of pre-, resistance training, and detraining. Also, sargent jump, reaction time and standing on one leg with eyes closed, resistance retraining appeared significantly improvement with pre- and detraining. In the 1-RM, dead lift of resisitance retraining appeared significantly higher than that of detraining. And bench press of resistance retraining appeared significantly higher than that of detraining. From these results, it was suggested that 12 weeks of resistance training may expected in keep the body healthy and improvement of physical fitness with respect to decrease of %fat, increase of physical fitness and 1-RM. In addition, detraining brought a negative result for body composition and fitness, but suggested that retraining after suitable rest could induced to positive physiological change.
