Beetroot Juice Effects on Contractile or Neuromuscular Properties in Male Trained Sprinters

NCT06675682 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 12

Summary

Beetroot juice is a rich source of nitrate (NO3-), which serves as a precursor to nitric oxide (NO) via the NO3- to nitrite (NO2-) to NO conversion pathway. This pathway is believed to enhance vasodilation and improve neuromuscular function, such as by increasing sarcoplasmic reticulum calcium release and re-uptake, leading to enhanced force production in type II muscle fibers and improved muscle contractile recruitment. Therefore, the aim of this study was to investigate the effects of beetroot juice supplementation on muscle contractile properties, as assessed by tensiomyography, and neuromuscular performance in sprint-trained athletes.

  • Placebo

Interventions

DIETARY_SUPPLEMENT

Beetroot Juice (Beet-It Stamina Shot) and Exercise Training

Player randomization was performed using an online tool (https://www.randomizer.org/). An independent researcher assigned alphanumeric codes to each sequence to ensure blinding of both sprint athletes and researchers during the trials. Each player participated in two identical experimental trials separated by one week to allow physical recovery between testing occasions and washout from the beetroot juice treatment.
