Background: Karate is a popular and often played martial sport. A short recovery is obtained by karate athletes during matches, so it requires an effective recovery strategy for athletes to be able to return to their initial condition. Research on watermelons has recently been popularly used in sports. Watermelon is considered to provide ergogenic relief for athletes. The rich content of l-citrulline in watermelon is a modulator of blood flow that can help muscle function, resistance to fatigue during exercise, and the athlete's recovery process. So that the consumption of watermelon juice for athletes will provide new findings, especially for athlete recovery. Methods: This clinical study was conducted with a one-way crossover design. The subjects of this research are PPLP West Java karate athletes who are the best karate student athletes from every region in the West Java region. The subject will go through two periods, the first period the subject does not consume watermelon juice, and the second period the subject consumes 500ml/day of watermelon juice for seven days. Data collection was carried out in the form of testing fatigue indicator variables, namely, blood lactate to find out how to clean blood lactate, countermovement jump to determine neuromuscular function, perceived recovery status to determine the level of perceived recovery, and anaerobic ability through running-anaerobic sprint test. Measurements were made after the sample had run the protocol in the form of a match simulation. Results: There were significant differences due to consumption of watermelon juice on lactate clearance in SP (immediately after the protocol), 5-min, and 10-min post protocol. A significant difference was also seen in the perceived recovery status where there was a significant difference after consumption of watermelon juice on SP, 48h and 72h post protocol. However, there was no significant difference in the value of the countermovement jump and the anaerobic ability of athletes after consuming watermelon juice. Conclusion: Consumption of watermelon juice can help athletes recover which has an effect on lactate clearance and perceived recovery status. But it does not help in the value of the countermovement jump and anaerobic ability.
