Description
Summary:This study analyzed the relationship between generic and judo-specific physical test performances and technical–tactical competition performances among 19 female judo athletes. Participant data were gathered in two stages: (a) physical tests—countermovement jump (CMJ), handgrip strength, Special Judo Fitness Test and Judogi Grip Strength Test; and (b) match performances recorded for technical–tactical analysis. Pearson’s linear correlation and multiple linear regression analysis showed no significant correlations between any technical–tactical parameter and judo-specific physical tests. However, the number of attacks during matches was significantly positively correlated with countermovement jump height (CMJJH; r = 0.69, p = .002), peak power output (CMJPPO; r = 0.53, p = .002), and peak velocity (CMJPV; r = 0.62, p = .001). Effective time during matches was significantly correlated with all CMJ parameters (except maximum force; r = 0.65−0.76, p ≤ .01) and with right hand grip strength (r = 0.48, p = .037). Match effectiveness was correlated with CMJPPO (r = −0.67, p = .001), mean power output (CMJMPO; r = −0.54, p = .017), and CMJPV (r = −0.54, p = .004). The explained power of variance was low for all variables at 45-54%. We conclude that judo-specific performance tests do not seem to be related to female judo athletes’ technical–tactical skills in official competition, though athletes with higher lower limb muscle power and higher handgrip strength showed higher time effectiveness during matches.
