Effect of squat with equalized load on the power of lower limbs of high-performance judo athletes

Abstract

Objetive: To evaluate the effect of a cargo squat session equalized in the contractile and elastic capacity of the lower limbs of elite judokers. Materials and Methods: seven male athletes (25.3 ± 3.8 years) performed five series of 12-RM in free squat. The power of the lower limbs was analyzed in three moments: before, during and after the session. Squat Jump and Countermovement Jump jumps were used to evaluate the power-related power and elastic strength of the lower limbs. The body composition was evaluated by the five component technique. The Friedman test was used to analyze the data, being significant p <0.05. Results: There was no difference at the height of Squat Jump (37.1 ± 4.5 vs. 35.5 ± 4.7 vs 35.6 ± 4.7 cm; p = 0.768) and Countermovement Jump (38.9 ± 4 , 3 vs. 40.1 ± 4.7 vs 38.5 ± 4.7 cm; p = 0.486) at the three moments of the session. However, there was a reduction of approximately 4% in the performance of the initial phase squad for intermediate, remaining stable at the end of the exercise (4% reduction at the height of the jump). Regarding Countermovement Jump, there was an increase of approximately 3% at the height of the initial jump to the intermediary, returning to the basal value at the end of the session (4% reduction in performance). Conclusion: An equalized external load did not interfere with the power of lower limbs in high yield judoks after an equalized load squat exercise.
