The aim of this research work is to inspect the influence of training and detraining impact on selected bio-motor abilities. To attain the study purpose, forty male inter-collegiate level players were considered as participants. The chosen player’s age, was ranged from 18 to 23 years. The chosen inter-collegiate players were randomly allocated into two equivalent groups of 20 players in both. Group-I performed concurrent resistance and aerobic training whereas group-II were acted as control. After the completion of twelve-weeks training period the subjects of group-I and II were physically detrained for thirty days. The data collected pre, post experimentation and during detraining were statistically analyzed by using two way (2 x 5) factorial ANOVA with last factor repeated measures. Statistical analysis found significant improving in muscular strength and Cardio respiratory endurance performance due to concurrent resistance and aerobic training and significant decline during detraining period.
