Effects of an 8-week high intensity interval training (HIIT) and ashwagandha supplementation on aerobic capacity, muscle oxygenation and haematological parameters in healthy men

Randomized Controlled Trial

Human

2025 Jul

The study compared two groups of men doing the same HIIT program - one group took ashwagandha and the other took a placebo. Both groups improved their aerobic capacity by similar amounts, meaning the ashwagandha didn't give any extra boost beyond what the exercise alone did.
