Relationships between power outputs measured from force-velocity test, Optojump test and Five-jump test in male shot putters

Abstract

Summary Purpose The purpose was to investigate relationships between force-velocity peak power output, Optojump average power output, 5-jump relative leg length power output and shot put performance. Methods Twelve shot putters participated in this study ( n = 12, age 18.8 ± 1.5 years, weight = 96.6 ± 8.8 kg, height = 178 ± 7 cm, BMI = 30.5 ± 3.2 kg·m −2 ). Force-velocity peak power output, Optojump average power output and 5-jump relative leg length power output were estimated using force-velocity test, Optojump test and 5-jump test, respectively. Shot put performances were measured during a simulated competition. Results Significant correlations were found between absolute value force-velocity peak power output (W) and leg muscle volume ( r = 0.80; P r = 0.77; P r = 0.81; P r = 0.63; P r = −0.25; r = 0.55), respectively. Conclusion The correlation between force-velocity peak power output (W) and shot put performance showed that force-velocity test constitutes a useful tool assessing peak power output in shot putter athletes. Optojump test and 5-jump test seem not to be accurate for such subjects. Technical abilities and fat mass probably constitute the limiting factor in shot putter during those tests.
