Effect Of Different Set Configurations On Barbell Velocity During Cleans.

The purpose of this study was to determine how different set configurations (constant and varying intensity) during training affect the velocity of the barbell during the clean lift. Methods: 15 Olympic weightlifters from Truman State University (9 men, 6 women) performed a clean workout consisting of 6 sets of single repetitions in both the constant (C) and varying (V) set configurations. In the C, 6 sets of single repetitions were performed at 85% of the subjects' 1 repetition maximum (1RM) clean and jerk. The V configuration had subjects perform 6 sets of singles at 80, 85, 90, 90, 85, and 80% of maximum clean and jerk. All subjects performed a standardized warm-up before each workout. All data were collected and analyzed with a V-Scope Weightlifting Analysis System. Peak velocity (PV) was analyzed for each repetition and compared between set configurations using repeated measures ANOVA. There was a significant time effect for the velocity (p = .007) and significant interaction effect for time x set configuration (p = .008). Tukey's HSD found no significant differences between velocities at any specific repetition. However, there was a trend towards a faster velocity in the 2nd repetition during C versus the 4th repetition of V. Differences in velocity between repetitions 1 &2 and 5 &6 by configuration showed a trend as well. Conclusion: This study shows that there are trends toward differences in velocities between the constant and varying set configurations during the clean lift. Practical Application: Varying load across the sets may produce greater variation in maximum barbell velocity. [ABSTRACT FROM AUTHOR]
