Effects of β-alanine and Sodium Bicarbonate Supplementation on Physical Capacity and Biochemical Markers Concentrations
Sponsor: Poznan University of Physical Education
Summary
This randomized, double-blind, placebo-controlled, parallel-group study aims to evaluate the potential synergistic effect of beta-alanine (BA) and sodium bicarbonate (SB) supplementation, compared to their separate administration or placebo (PL), on physical performance and selected blood biochemical markers in highly trained female basketball players.

Interventions
BA and SB supplementation
Assigned Interventions: * Beta-alanine (BA) * Sodium bicarbonate (SB) Description: • Participants receive beta-alanine and sodium bicarbonate Intervention list \& supplementation details: 1. Beta-alanine (BA) * Form: Gelatin capsules * Substance: Pure beta-alanine * Daily dose: 6.4 g/day * Dosing schedule: Four equal servings taken with meals (breakfast, lunch, snack, dinner) * Supplementation period: days 1 to 28 2. Sodium bicarbonate (SB) * Form: Gelatin capsules * Substance: Pure sodium bicarbonate * Daily dose: 0.3 g/kg body mass per day * Dosing schedule: Three equal servings taken with meals (breakfast, lunch, dinner) * Supplementation period: days 21 to 28 of BA or PL1 supplementation Rationale: • This group tests the combined effects of BA and SB
BA and PL2 supplementation
Participants in this intervention group will undergo chronic supplementation with beta-alanine (BA) and an inert placebo (PL2) matched to the sodium bicarbonate (SB) protocol. * Beta-alanine (pure, in gelatin capsules) will be administered at a total daily dose of 6.4 g, divided into four servings taken with meals, over a period of 28 consecutive days. * PL2 (placebo matched to SB, in gelatin capsules) will be administered from Day 21 to Day 28 of beta-alanine supplementation, at a daily dose of 0.3 g per kg of body mass, divided into three equal servings taken with meals. This group allows for evaluation of the isolated effects of BA supplementation when combined with a placebo comparator to SB
PL1 and SB supplementation
Assigned Interventions: * Placebo matched to BA (PL1) * Sodium bicarbonate (SB) Description: • Participants receive only sodium bicarbonate as the active compound and placebo capsules matching the BA protocol. Intervention list \& supplementation details: 1. Placebo matched to BA (PL1) * Form: Gelatin capsules * Substance: Inert substance matched in appearance and dosing schedule to BA * Daily dose: 6.4 g/day * Dosing schedule: Four equal servings taken with meals (breakfast, lunch, snack, dinner) * Supplementation period: days 1 to 28 2. Sodium bicarbonate (SB) * Form: Gelatin capsules * Substance: Pure sodium bicarbonate * Daily dose: 0.3 g/kg body mass per day * Dosing schedule: Three equal servings taken with meals (breakfast, lunch, dinner) * Supplementation period: days 21 to 28 of BA or PL1 supplementation Rationale: • This group tests the isolated effects of SB
PL1 and PL2 supplementation
Assigned Interventions: * Placebo matched to BA (PL1) * Placebo matched to SB (PL2) Description: • Participants receive two matched placebos. Intervention list \& supplementation details: 1. Placebo matched to BA (PL1) * Form: Gelatin capsules * Substance: Inert substance matched in appearance and dosing schedule to BA * Daily dose: 6.4 g/day * Dosing schedule: Four equal servings taken with meals (breakfast, lunch, snack, dinner) * Supplementation period: days 1 to 28 2. Placebo matched to SB (PL2) * Form: Gelatin capsules * Substance: Inert substance matched in appearance and timing to SB * Daily dose: 0.3 g/kg body mass per day * Dosing schedule: Three equal servings taken with meals (breakfast, lunch, dinner) * Supplementation period: days 21 to 28 of BA or PL1 supplementation Rationale: • This serves as the control group for comparison with all active intervention arms.
