About this study

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.

Treatment and study plan

Regular consumption of natural mineral water Borjomi® with high bicarbonate content

Other

Natural mineral water Borjomi® is a transparent mineral water with specific alkaline taste and smell. The chemical composition includes sodium hydrocarbonate (HCO2-) 3995 mg/l (3500-5000 mg/l), chlorides (Cl-) 360 mg/l (250-500 mg/l), and nitrites (NO2-) <0.005 mg/l (up to 1 mg/l). The "Borjomi" water was packaged into standardized unlabeled 500 ml bottles. Participants were prescribed with 2 bottles (1000 ml) of daily consumption for 14 days. In order to maintain their usual water regimen, the participants additionally consumed steal drinking water on demand. The day before testing, participants were asked to abstain from their routine training and other physical activities.

Other names: Borjomi

Regular consumption of processed drinking water Smart Spring®

Other

Processed drinking water Smart Spring® has no colour and smell with delicate specific taste. The chemical composition includes sodium (Na+) 33.6 mg/l, magnesium (Mg2+) 10.03 mg/l, calcium (Ca2+) 34.57 mg/l, chlorides (Cl-) 69.79 mg/l, sulfates (SO42-) 22.00 mg/l, and hydrocarbonates (HCO2-) 96.48 mg/l. The Smart Spring® water was packaged into standardized unlabeled 500 ml bottles. Participants were prescribed with 2 bottles (1000 ml) of daily consumption for 14 days. In order to maintain their usual water regimen, the participants additionally consumed steal drinking water on demand. The day before testing, participants were asked to abstain from their routine training and other physical activities.

Other names: Smart Spring®

Regular consumption of still drinking water

Other

Still drinking water Святой Источник®is a standard steal drinking water, that has no colour, taste, and smell. The Святой Источник® water was packaged into standardized unlabeled 500 ml bottles. Participants were prescribed with 2 bottles (1000 ml) of daily consumption for 14 days. In order to maintain their usual water regimen, the participants additionally consumed steal drinking water on demand. Participants were asked to abstain from mineral water consumption for the entire observation period.

Other names: Water

Primary outcomes

  1. Changes of Relative Peak Power (W/kg)

    Time frame: 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.

  2. Changes of Fatigue Index (%)

    Time frame: 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.

Secondary outcomes

  1. Changes of Acid-Base Balance

    Time frame: 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.

  2. Changes of Lactate levels

    Time frame: 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.

  3. Changes of Attention stability

    Time frame: 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.
