Abstract Details

RESULTS: Repeated measures ANOVA revealed that performance measures were significantly higher during the JS compared to the HC for peak force, peak velocity, and peak power. Analysis at the ankle, knee, and hip joints also showed peak joint angular velocities for JS to be significantly higher than HC in all 3 joints. When comparing the relative intensities, peak velocity and peak power were higher at 40 and 60%, than 80% 1RM with no difference between 40 and 60% 1RM. CONCLUSION: Performing the JS at intensities between 40 and 60% 1RM of the HC creates higher loading and joint angular velocities for developing power compared to using the HC at similar intensities. PRACTICAL APPLICATIONS: The JS is a simple task to master as compared to the HC and is typically a lead-up exercise used to teach the HC. According to our results the use of the JS in weekly programming may create a greater training stimulus for developing overall power than using the HC alone. In addition, teaching or supervising the performance of the HC may be limited by time or ratios of coaches to athletes. When athletes are not training for competitive weightlifting, where the catch of the HC is important to learn, consider performing the JS as part of the explosive training program. Funding for this project was received in a grant from the Graduate Student Research, Service and Education Leadership Grant Program at the University of Wisconsin-La Crosse.
