Key Points

This study aims to determine if acute beetroot juice ingestion affects sprint performance and neuromuscular function in trained male sprinters.
Participants ingested beetroot juice and performed a countermovement jump, squat jump, and 60 and 100 m sprint tests 150 minutes post-ingestion.
Contractile properties of muscles like rectus femoris, biceps femoris, gastrocnemius lateralis, and gastrocnemius medialis were assessed using tensiomyography.
Beetroot juice did not significantly enhance sprint performance or neuromuscular function.
Tensiomyography measurements revealed no improvements in muscle contractile properties after ingestion.

Abstract

INTRODUCTION: The aim of this study was to evaluate the acute effect of beetroot juice ingestion on sprint performance and neuromuscular properties of male trained sprinters. METHODS: -). Participants performed a countermovement jump, a squat jump, and 60 and 100 m sprint tests at 150 minutes after ingestion. Before and after these performance tests, contractile properties of the rectus femoris, biceps femoris, gastrocnemius lateralis, and gastrocnemius medialis muscles were measured with tensiomyography. RESULTS: = 0.047). CONCLUSION: - did not enhance sprint performance or the neuromuscular function of male trained sprinters.Trial registration: The study was retrospectively registered in ClinicalTrials.gov with the following ID: 5-56NCT06675682 by 1 November 2024.
