摘要：The aim of this study was the assessment of progressive low-dose sodium bicarbonate (NaHCO 3 ) supplementation on the anaerobic indices in two bouts of Wingate tests (WT) separated by wrestling-specific performance test and assessing the gender differences in response. Fifty-one (18 F) wrestlers completed a randomized trial of either a NaHCO 3 (up to 100 mg·kg -1 ) or a placebo for 10 days. Before and after treatment, athletes completed an exercise protocol that comprised, in sequence, the first WT 1 , dummy throw test (DT), and second WT 2 . The number of completed throws increased significantly in males from 19.3 ± 2.6 NaHCO 3pre to 21.7 ± 2.9 NaHCO 3post . ΔWT 2 -WT 1 improved particularly in the midsection of 30-s WT on NaHCO 3 . However, no significant differences were found in peak power (PP), power drop (PD) and average power (AP) (analyzed separately for each WT), and ΔWT 2 -WT 1 in PP and PD. Interaction with gender was significant for AP, PP and PD, every second of WT 1 and WT 2 , as well as DT test. In conclusion, our study suggests that the response to NaHCO 3 may be gender-specific and progressive low-dose NaHCO 3 supplementation allows the advantageous strengthening of wrestling-specific performance in males. It can also lead to maintenance of high anaerobic power mainly in the midsection of the 30-s Wingate test.
