Quantifying Performance Characteristics of an International Level Male Weightlifter
PURPOSE: To quantify squat jump and isometric mid-thigh pull performance characteristics of an international level male weightlifter relative to a group of male weightlifters at an Olympic training site. METHODS: An 85kg international level male weightlifter (22.0y, 81.63kg, 168.5cm) representing the USA was recruited for this study and compared to a group of male weightlifters (n=41, 24.2±4.6y, 93.14±21.10kg, 173.8±8.6cm). Data was collected as part of an on-going athlete monitoring program and athletes were familiar with all tests performed. Unloaded squat jumps and isometric mid-thigh pulls were performed on force plates sampling at 1000Hz and analyzed with LabView software. Variables analyzed included squat jump height (JH) and allometrically scaled peak power (PPa), isometric mid-thigh pull allometrically scaled peak force (IPFa) and rate of force development at 200ms (RFD200). Standardized (z) scores were calculated for the athlete on each testing variable. RESULTS: Testing results for the athlete and group were as follows: JH=47.0 vs. 33.9±6.1cm (z=2.13), PPa=309.14 vs 278.68±81.76W·kg0.67 (z=0.37), IPFa=263.78 vs 270.31±48.27N·kg0.67 (z= -0.14), RFD200=4701.93 vs 10241.4±5422.6N·s-1 (z= -1.02). CONCLUSION: Despite having the highest absolute (total=326kg) and relative (Sinclair=389.54) weightlifting total, the only variable that corresponded with the athlete’s competition success was JH. These findings suggest that coaches and sport scientists can use squat jumps to predict competition success and identify talent in male weightlifters.
