The Effect of Sodium Bicarbonate Supplementation on Wrestling-Specific Performance and Fatigue Markers

Abstract

The aim of this study was to evaluate the effects of a five-day sodium bicarbonate supplementation regimen on wrestling-specific anaerobic performance and fatigue markers. Fifteen male wrestlers, aged between the mean age of 18.53 ± 0.74, and all actively engaged in wrestling, participated in the study. Wrestlers received sodium bicarbonate supplementation at a dose of 0.3 g.kg-1 for five consecutive days. Performance was assessed before and after supplementation using a wrestling-specific suplex throw test. Additionally, lactate and blood gas parameters were analyzed from fingertips and intravenous blood samples. Lactate levels significantly increased post-exercise; however, no significant difference was found between pre- and post-supplementation levels (p>0.05). On the other hand, dummy throw performance significantly improved (p<0.05). Blood gas analysis revealed statistically significant changes in pH, pCO₂, HCO₃⁻, sO₂, and FO₂Hb parameters. These findings suggest that the supplementation contributed to performance enhancement by inducing a state of metabolic alkalosis. This study demonstrated that five days of sodium bicarbonate supplementation may enhance performance in sports like wrestling, which involve short-duration, high-intensity efforts. Although no significant changes in lactate levels were observed, the performance improvement is thought to result from the buffering of hydrogen ions and the maintenance of acid-base balance.
