This study aimed to verify the effect of judo matches on handgrip strength and perceptual responses during an official tournament in medalists and nonmedalists. Thirty-four male judo athletes participated in an offi-cial judo tournament. Before the first match and immediately after each match, maximum isometric handgrip strength and rate of perceived ex-ertion overall and in specific areas were assessed. Analysis of variance for repeated measures was used to compare variables before the first match and after each match, and t-test was used to compare medalists and nonmedalists with the level of significance set at 5%. Also, effect size (ES) analysis was used. The results showed decrease in handgrip strength in both hands from the third match (P<0.05). The rate of per-ceived exertion (RPE) increased from the first match and remained high over the subsequent matches (P<0.001). A very large effect for nonmed-alist group (ES=3.44) and large effect for medalist group (ES=1.94) was found in the third match compared to prematch. Forearm and fingers were the body regions most cited by athletes in both groups. We con-cluded that an official judo competition induced significant drop in hand-grip strength from the third match and increased the RPE from first match. Medalists seem to have better recovery after the third match compared to nonmedalists.
