What this trial studies
This study investigates the impact of sodium bicarbonate supplementation on endurance performance specifically in recreational female runners. It aims to explore how sodium bicarbonate, known for its buffering capacity, can enhance performance during prolonged high-intensity exercise while minimizing gastrointestinal discomfort through a carbohydrate-rich meal protocol. The research focuses on female athletes, a group often underrepresented in sports performance studies, to understand the unique physiological effects of sodium bicarbonate on their endurance capabilities.
Who should consider this trial
Good fit: Ideal candidates for this study are recreational female runners aged 18-40 who have been training regularly for at least a year and can complete a 10 km race at a pace below 6.00 min/km.
Not a fit: Patients with acute or chronic conditions affecting physical activity, or those with gastrointestinal disorders, may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide female athletes with an effective strategy to improve their endurance performance during high-intensity running.
How similar studies have performed: While some studies have shown positive effects of sodium bicarbonate on performance, this specific focus on female athletes is relatively novel and underexplored.
