Abstract

Introduction: This study investigated the effect of ingesting a sodium bicarbonate drink on specific physiological indicators following high-intensity exercise in advanced basketball players.

Objective: The research aimed to assess the drink's impact on the fatigue index, anaerobic capacity, and blood lactate levels after intensive exercise.

Methodology: The sample comprised sixteen players aged 19 to 27 years, divided into two groups. The experimental group received the sodium bicarbonate drink, whilst the control group received a placebo. All participants underwent standard pre- and post-tests for the measured variables.

Results: The results demonstrated a notable improvement in the fatigue index and anaerobic capacity, alongside a significant decrease in lactate levels within the experimental group compared to the control group.

Discussion: These findings align with several previous studies which indicated the potential role of external alkalising agents in enhancing high-intensity exercise performance by improving acid-base balance.

Conclusions: The study concluded that a sodium bicarbonate drink reduces anaerobic fatigue and improves energy utilisation efficiency in athletes. Future research should focus on determining optimal dosages and timing for consumption.
