sodium hydrogencarbonate — increases peak power output
Evidence strength: moderate.Finding“There was a significant effect of condition for peak power (Fig. 2A; F1,9 = 8.45, p = 0.02), demonstrating an average of 21 W (3.4%) higher in the SB condition across the duration of the 20 sprints.”

- crossover
- Dose
- 0.2 g/kg body weight in gelatin capsules, four equal doses every 15 min over 45 min before exercise; corn starch placebo
- Population
- Ten recreationally endurance-trained adults (six male), 4 sets of 5 six-second maximal standing cycling sprints in a 40 C heat chamber; peak power averaged across the 20 sprints

sodium hydrogencarbonate — increases mean power output
Evidence strength: moderate.Finding“Similarly, average power was 13 W (2.3%) higher in the SB condition (condition effect: F1,9 = 6.63, p = 0.03, Fig. 2C), reflecting higher average power with SB across the 20 sprints.”

sodium hydrogencarbonate — no detected effect on core body temperature
Evidence strength: moderate.FindingNull result“There was no effect of SB on heart rate (condition effect F1,9 = 0.29, p = 0.61; interaction effect: F19,171 = 0.54, p = 0.94) or core temperature (condition effect F1,9 = 2.94, p = 0.12; interaction effect: F3,19 = 0.76, p = 0.53) (Fig. and B).”
