Background: The purpose of the study was to determine the influence of pre-competition rehydration on cardiac electrical profile, electrolyte balance, perception of effort during high-intensity wrestling bouts. Methods: 10 adult male middleweight wrestlers underwent a crossover design, performing 2 trials: pre-emptive rehydration and no rehydration. Pre-match rehydration was executed by ingestion of an electrolyte solution (sodium 500 mg, potassium 200 mg, magnesium 100 mg) 3 hours before game time supplemented by another 250 mL 30 minutes before game time. Compared to the control condition. Result: the current result showed that the pre-emptive rehydration attenuated (QT interval: 408 ± 18 ms, HRV: 58 ± 7 ms) and recovered electrolyte level (sodium, potassium, and magnesium) during diarrhea. During the rehydration period, participants reported Decreased subjective fatigue, with a perceived exertion of 7.1 ± 1.2, compared with the ME alone. Sweat loss was also greatly attenuated in the intervention arm (0.5 ± 0.3 kg). Conclusion: These results also suggest that pre-exercise rehydration can contribute to better cardiovascular stability and Enhance performance and less fatigue in high intensity sports. These findings highlight the need for appropriate hydration practices in combat sport to maximize performance while reducing health risks.
