- 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.

Group Intervention Description Borjomi Regular consumption of natural mineral water Borjomi® with high bicarbonate content Healthy volunteers (N16, 8 males and 8 females) 30.63±1.04 y.o. with BMI 22.17±0.75 kg/m2 were randomly allocated to Borjomi group. Participants received 30 bottles (500 ml) of natural mineral water Borjomi® for daily 1000 ml (2 bottles) water consumption for 14 days (from visits 1 and 2). Participants drank the first bottle on the visit 1 after the first study Wingate test and the last bottle on the visit 3 before the second study Wingate test Smart Spring Regular consumption of processed drinking water Smart Spring® Healthy volunteers (N16, 8 males and 8 females) 28.56±1.61 y.o. with BMI 23.14±0.60 kg/m2 were randomly allocated to Smart Spring group. Participants received 30 bottles (500 ml) of processed drinking water Smart Spring® for daily 1000 ml (2 bottles) water consumption for 14 days (from visits 1 and 2). Participants drank the first bottle on the visit 1 after the first study Wingate test and the last bottle on the visit 3 before the second study Wingate test. Control group Regular consumption of still drinking water Healthy volunteers (N16, 8 males and 8 females) 30.69±1.74 y.o. with BMI 22.67±0.51 kg/m2 were randomly allocated to Control group. Participants received 30 bottles (500 ml) of steal drinking water Святой Источник® for daily 1000 ml (2 bottles) water consumption for 14 days (from visits 1 and 2). Participants drank the first bottle on the visit 1 after the first study Wingate test and the last bottle on the visit 3 before the second study Wingate test.
- Primary Outcome Measures
Name Time Method Changes of Fatigue Index (%) 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) 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.
- Secondary Outcome Measures
Name Time Method 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. Cubtal veins were catheterized with Peripheral venous catheters on visits 1 (day 3) and 2 (day 16) before Wingate anaerobic test. The venous blood samples were collected three times in rest, after Wingate anaerobic test, and after 5 minutes recovery-period on visits 1 (day 3) and 2 (day 16). After the last sample collection the catheter was removed (at the same day). The blood samples were immediately analyzed for Lactate levels according to standard laboratory procedures.
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. Cubtal veins were catheterized with Peripheral venous catheters on visits 1 (day 3) and 2 (day 16) before Wingate anaerobic test. The venous blood samples were collected three times in rest, after Wingate anaerobic test, and after 5 minutes recovery-period on visits 1 (day 3) and 2 (day 16). After the last sample collection the catheter was removed (at the same day). The blood samples were immediately analyzed for Acid-Base Balance according to standard laboratory procedures.
Changes of Attention stability 4 times: visit 1 - baseline and after Wingate test; visit 2 - baseline and after Wingate test. Attention stability was assessed in rest and after Wingate anaerobic test on visits 1 (day 3) and 2 (day 16). For attention stability assessment the standard 5x5 Schulte Table testing with calculation of work efficiency, work warm-up and psychological stability was used.
