Abstract

Acute supplementation of Sodium Bicarbonate (SB) is suggested as ergogenic, however may cause Gastrointestinal Discomfort (DGI). Therefore, the aim of this study was to observe whether the fractionated dose of SBingested with carbohydrates promote an ergogenic effect in physically active individuals without DGI. The study included five recreational physically active and healthy subjects (age: 19 ±4.45 years, weight: 68.4 ±4.04 kg and, height: 174.5 ±1 cm) which consumed four times, separated by 4 hours, 5g of SB in capsules together with 1.5gm·Kg-1 of carbohydrate diluted in 7ml·Kg-1of water (situation BS) or a placebo dose of 3.5g of artificial juice diluted in 350ml of water, 30 minutes before test (situation P). After supplementation, subjects performed an experimental physical stress test-PST to volitional fatigue. As results there was no difference (p<0.05) in Heart Rate-BPM (P: 189.48 ±13; BS: 188.10 ±9 p=0.645) and Perceived Exertion-Borg (P: 17.96 ±3; BS: 17.41 ±4, p= 0.506) between situations (P vs.BS), however, there were significant differences in the concentrations of lactate-mmol-L (P: 17.96 ±3; BS: 17.41 ±4, p=0.506) and total activity time until volitional fatigue (P: 376.20’’ ±130.66’’; BS: 461.00’’ ±218.34’’, p= 0.000). Do not was reported by the subjects any kind of discomfort due to supplementation protocols. We concluded that supplementation of SB divided into four doses ingested with carbohydrate may be effective for increase the performance without GID in healthy recreational physical activity subjects.
