dc.description.abstract Decrements in performance with resistance training and performance variables such as power, force, and velocity has been noted in a variety of exercises. Implementation of Inter-Repetition Rest (IRR) treatments has been shown to negate the effects of neuromuscular fatigue and performance decrements. To investigate the effects of Inter-Repetition Rest on the snatch pull exercise in regard to performance variables of power, force, and velocity. Nine recreationally resistance trained men (Age: 28.125 ± 3.99 years, Height: 181.92 ± 4.88 CM, Weight: 87.155 ± 8.99 KG, One Repetition Snatch Maximum/BW: 1.17 ± .100) volunteered for this study. This study used a randomized single blind experimental design, and subjects were randomly assigned to treatment order. Treatments included (P0), (P10), and (P20), representing seconds of IRR per treatment. Each subject completed one session of each randomly assigned treatment, with three sets of five repetitions in the snatch pull exercise. Velocity and force were measured using the VICON Real-Time Motion Analysis and AMTI Force plate, respectively. Power output was calculated from force and velocity measures. A One Way Repeated ANOVA was utilized on mean peak values for power, force, and velocity to determine the within-subject treatment effects with repetitions and sets. A One Way Repeated ANOVA was utilized on peak mean values between treatment groups of IRR. Main effect differences were then further analyzed at 95% Confidence Intervals. An Alpha level of 0.05 was used to determine significance. Overall mean peak values between treatment groups showed statistical significance between all groups (P0), (P10), and (P20), for power, force, and velocity measures (P<.05). Mean peak force values between protocols were 1892 ± 140.87 N, 1824 ± 175.53 N, 1744 ± 262.68 N for P20, P10, and P0 respectively. Mean peak velocity values between protocols were 1.69 ± .15 m/s, 1.63 ± .14 m/s, 1.59 ± .14 m/s for P20, P10, and P0 respectively. Mean peak power values between protocols were 2821 ± 347 W, 2638 ± 435.77 W, 2497 ± 486.37 W for P20, P10, and P0 respectively. Decrements in performance percentage between treatments and force values were taken as a percentage of P20 being 100%. P10 and P0 were lower than P20 treatment by 3.9%, and 8.11%, respectively. P10 and P0 were lower than P20 treatment by 3.5%, and 5.92%, respectively. P10 and P0 were lower than P20 treatment by 6.48%, and 11.48%, respectively. Conclusion: IRR treatment of P10 and P20 elicited overall higher mean peak values in comparison to P0. IRR treatment of P20 was significantly higher than all other treatments. Based on this study, implementation of IRR can help to maintain performance variables often that are affected by neuromuscular fatigue seen with continuous repetitions. en_US
