Beetroot juice has actually been obtaining a great deal of interest recently because of its performance-enhancing effects through enhancing nitrate manufacturing, which enhances vasodilation. Researchers wished to examine if there would be any added performance-enhancing impacts if they stacked beetroot with Caffeine. Fourteen well-trained men executed four trials on different celebrations. The groups were designated to either:
- Placebo plus 5mg/kg caffeine
- Beetroot juice providing 8mmol of nitrate
- Beetroot juice plus caffeine
Participants cycled at 60% maximal oxygen uptake for 30 mins, complied with by a time to fatigue (TTE) trial at 80% max. Saliva was accumulated before supplement ingestion, before exercise, and also after the workout to exhaustion test for salivary nitrate, nitrite, and cortisol analysis. At the end of the study, in beetroot trials, saliva nitrate as well as nitrite boosted > 10-fold before workout contrasted with pre-ingestion.
Exercise to exhaustion with beetroot and caffeine was 46% higher than in the placebo and 18% more than with beetroot alone and 27% higher than caffeine alone.
Here’s another example of supplement synergy where combining beetroot and caffeine has additive effects on exercise performance compared with either beetroot or high levels of caffeine alone. – FLEX
