Abstract:
Sport performance is affected by various individual and environmental factors. But often the same factor exerts effects on individuals differently which proposes the probability of the role of other effective mediating factors. The aim of the present study was to investigate the effect of temperament type and sodium bicarbonate supplementation on anaerobic power and fatigue index. For this purpose, 200 students volunteered to participate in the study, and 40 students who had distinct cold and hot temperaments and other inclusion criteria were selected and divided into cold (n=20) and hot (n=20) groups based on their temperament. Subjects participated in two sessions of RAST test by one-week interval, after consuming placebo or supplementation in a crossover method. Sodium bicarbonate supplementation increased maximum and mean anaerobic power in hot group and mean anaerobic power in cold group, but it did not significantly affect fatigue index in both groups. A comparison between hot and cold temperament groups indicated that following supplementation, maximum and mean anaerobic power was higher in hot temperament group than cold temperament group, but fatigue index was lower in cold temperament group than hot temperament group. Temperament type (without supplementation) did not have a significant effect on maximum and mean anaerobic power and fatigue index. In conclusion, temperament type per se does not have an effect on anaerobic power indices, but sodium bicarbonate supplementation improves anaerobic power in hot temperament group, and significantly decreases fatigue index in cold temperament group more than hot temperament group.
