Improved Endurance: Beetroot extract is rich in nitrates, which your body converts to nitric oxide. Nitric oxide helps relax and widen blood vessels (vasodilation), leading to increased blood flow and oxygen delivery to your muscles. This can improve exercise efficiency and delay fatigue, crucial for the endurance demands of HYROX (running and sustained functional movements).   

Enhanced Oxygen Utilization: By improving blood flow, beetroot extract may help your muscles use oxygen more efficiently. This can allow you to perform at higher intensities for longer periods, which is beneficial for both the running portions and the strength-based stations in HYROX.   

Increased Power Output: Some research suggests that beetroot supplementation might improve power and performance during high-intensity exercise. This could be relevant for the strength components of HYROX, such as sled pushes, pulls, and wall balls.   

Faster Recovery: The increased blood flow promoted by nitric oxide may also help with post-workout recovery by delivering nutrients and removing waste products from the muscles more effectively. Some studies suggest it can reduce muscle soreness.

Improved Muscle Contraction: Nitric oxide might also play a role in improving the release and use of cellular calcium, which is essential for muscle contraction speed. This could be beneficial for the dynamic movements in HYROX.
