Methods: Eighteen male judo athletes participated in the study and were divided into two groups: control and rapid weight loss (RWL). RWL athletes were given 48 h to cut 5% of their body mass while the control group followed their routines. Athletes performed three measurements, including hydration, body mass and three consecutive special judo fitness tests (SJFTs). At the 1st and 6th minutes following each SJFT and 1st, 6th and 15th minutes following the last SJFT, blood lactate and heart rate (HR) was monitored. Results: The effect of RWL on variables was tested with split‐plot ANOVA. RWL significantly affected urine specific gravity with a higher value following weight loss compared to baseline and recovery (F2‐32 = 13.2, p < 0.001). In addition, athletes’ SJFT total throw numbers differed among measurements (F2‐32 = 7.70, p < 0.001). Athletes presented worse SJFT index after weight loss (F2‐ 32 = 8.05, p = 0.01; F1‐16 = 6.43, p = 0.02, respectively). HR changed significantly among measurements days and times (F28‐448 = 143.10, p < 0.001). Conclusion: RWL induced dehydration and impaired heart rate recovery in highly trained judo athletes, and they could not rehydrate between competition simulated weigh‐in and 15 h of recovery.
