Brief summary: The effects of 2 weeks 1000 ml daily mineral water Borjomy® consumption of anaerobic performance and acid-base balance in comparison with purified electrolite smart-water and still drinking water.

Detailed description: Bicarbonate supplementation increases the efficiency of the body's buffer systems and improves anaerobic performance in athletes when taking bicarbonate just before training. In the course of studies, a similar effect was confirmed for professional swimmers at a distance of 200 meters freestyle, cyclists at distances up to 3 km and track and field athletes in steeplechase. However, these studies were conducted on professional male athletes, and it is interesting to compare the effects with non-athletes population.

Borjomi® is a natural bicarbonate sodium mineral water with high taste qualities. The effects of Borjomi® as bicarbonate source on physical performance are another research interest.

The aim of this study was to evaluate the comparative effectiveness of the regular use of bicarbonate-containing mineral water (Borjomi®) on anaerobic performance and acid-base balance during short-term physical activity of high intensity in comparison with purified electrolite smart-water and still drinking water.
