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

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.
