Aim: To find out effect of circuit resistance training on upper limb muscle strength in volleyball attacker players. Objectives: To study effect of circuit Resistance Training on strength of triceps, deltoid, shoulder internal rotator muscles and on workout volume in volleyball attacker players. Procedure: 30 Subjects were collected according to inclusion and exclusion criteria. Consent was taken from respective subjects to conduct the study. Respective protocol was followed for Group A (Controlled Group) and Group B (Experimental Group); over 5 weeks, with 3 sessions per week .Pre and post values of Subjects were assessed by using 10 RM and Push up test. The statistical tests used for analysis of result were: Paired t-test and unpaired t- test. Mean standard deviation and standard error was carried out for both groups. Result: After 5-weeks of training period, the B group showed more improvement in Strength of Triceps (P< 0.050) considered significant, Deltoid (p< 0.040) considered significant, Shoulder internal rotators(p<0.030) considered significant and Push up performance (p<0.000) Considered extremely significant. Conclusion: This study concludes that Circuit Resistance Training is more effective in improving the strength of shoulder internal rotators, deltoid and triceps Muscles as compare to regular Training in volleyball players.
