简要总结
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.
详细描述
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.

盲法说明
The intervention (drinking water) was masked for participants through the same indistinguishable bottle design, whereas the taste of the water was different. The research team was unmasked as visits for participants from comparable groups assigned for separate days in order to prevent the possible discussion of water taste between groups.

结局指标
主要结局
Changes of Fatigue Index (%)
时间窗: Twice: Baseline (visit 1) and in 2 weeks (visit 2).
The Fatigue Index was evaluated as percentage of power lost by repeated 30-seconds low limb Wingate anaerobic test with 7.5% from body mass workload in accordance with standard Wingate anaerobic test procedure with individual adjustment of angle and height of handlebar, seat height and foot straps. The test was preceded by a 5 min warm-up with a 4.5% from body mass workload. The day before testing, participants were asked to abstain from their routine training and other physical activities.
Changes of Relative Peak Power (W/kg)
时间窗: Twice: Baseline (visit 1) and in 2 weeks (visit 2).
The Dynamic of Relative Peak Power was evaluated by repeated 30-seconds low limb Wingate anaerobic test with 7.5% from body mass workload in accordance with standard Wingate anaerobic test procedure with individual adjustment of angle and height of handlebar, seat height and foot straps. The test was preceded by a 5 min warm-up with a 4.5% from body mass workload. Wingate anaerobic test were performed by each participant on visit 1 (day 3) and visit 2 (day 16). On visit 0 (day 1) the training Wingate anaerobic test with 4.5% from body mass workload was conducted to familiarize the participants with the testing procedure. The day before testing, participants were asked to abstain from their routine training and other physical activities.
次要结局
- Changes of Lactate levels(6 times: visit 1 - baseline, after Wingate test, and in 5 minutes recovery-period; visit 2 - baseline, after Wingate test, and in 5 minutes recovery-period.)
- Changes of Acid-Base Balance(6 times: visit 1 - baseline, after Wingate test, and in 5 minutes recovery-period; visit 2 - baseline, after Wingate test, and in 5 minutes recovery-period.)
- Changes of Attention stability(4 times: visit 1 - baseline and after Wingate test; visit 2 - baseline and after Wingate test.)
