Short-term co-ingestion of creatine and sodium bicarbonate improves anaerobic performance in trained taekwondo athletes.
Study Goal
The researchers aimed to determine whether co-ingestion of creatine (CR) and sodium bicarbonate (SB) enhances anaerobic performance in taekwondo athletes compared to CR or SB alone.
Results Summary
The study found that short-term ingestion of SB alone improved anaerobic performance, and co-ingestion with CR further enhanced mean power (MP) compared to either supplement alone, with similar peak power (PP) improvements.

Effective Dosage
0.5 g·kg⁻¹ of SB (specific frequency not stated).
Duration
Not specified in the abstract.

BACKGROUND: Creatine (CR) and sodium bicarbonate (SB) alone improve anaerobic performance. However, the ergogenic effects of CR and SB co-ingestion on taekwondo anaerobic performance remains unknown. METHODS: Forty trained taekwondo athletes (21 ± 1 y.; 180.5 ± 7.3 cm; 72.7 ± 8.6 kg) were randomized to: (i) CR and SB (CR + SB; 20 g of CR+ 0.5 g·kg RESULTS: PP and MP increased over time (P < 0.05) following CR + SB, CR, and SB ingestion, with no changes in the PLA or CON groups. There was a greater increase over time in MP following CR + SB (Absolute Δ: 1.15 ± 0.28 W∙kg CONCLUSION: Short-term CR and SB alone enhance TAIKT performance in trained taekwondo athletes. Co-ingestion of CR and SB augments MP compared to CR and SB alone, with similar PP improvements.
