Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Beetroot juice supplementation has shown the capacity for provoking different physiological effects (e.g. vasodilation and muscle contraction increments). However, the effects of beetroot juice ingestion on neuromuscular performance in women older adults are barely studied. In this randomized placebo-controlled study, we investigated the effects of beetroot acute supplementation in improving neuromuscular performance in women older adults

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Beetroot juice supplementation has shown the capacity for provoking different physiological effects that could affect human performance (e.g. vasodilation and muscle contraction increments). Although this dietary supplement has been commonly used for improving sports performance in recreational or professional athletes, the scientific literature in older adults is scarce. Thus, in our knowledge, no previous studies have analyzed the side effects associated to ingestion in this population group. In this randomized placebo-controlled study, we investigated the effects of beetroot acute supplementation in improving neuromuscular performance and side effects associated with ingestion in women older adults.
