Caffeine and Beetroot Juice Optimize 1,000-m Performance: Shapley Additive Explanations Analysis
How Caffeine and Beetroot Juice May Improve 1,000-Meter Running Performance
AI simplified
Abstract
Participants using caffeine and beetroot juice combined improved their 1,000-m run performance significantly compared to placebo.
- Caffeine (6 mg/kg body weight) and beetroot juice (70 mL) were tested for their effects on running performance in healthy male participants.
- The combination of caffeine and beetroot juice led to better performance in the first and second 1,000-m runs compared to placebo and beetroot juice alone.
- Performance declined after recovery in both beetroot juice and placebo groups, while it improved in the combination group.
- Post-exercise heart rate and blood lactate levels were highest in the caffeine and beetroot juice group.
- analysis identified body fat percentage, weight, and age as the most important factors influencing performance.
