Beetroot Juice Ingestion and Vertical Jump Performance (BEET_JUMP)

Acute Effects of Beetroot Juice Ingestion on Components of Vertical Jump Performance

Beetroot juice is a dietary supplement with good evidence for improving sports performance in different sport contexts, however, the evidence about the effects of beetroot juice in jump capacity is unclear. Thus, the aim of this study was to conduct a comprehensive examination of beetroot juice effects on vertical jump performance

Study Overview

• Status: Completed
• Conditions: Dietary Supplements
• Intervention / Treatment: Dietary supplement: Beetroot juice

Detailed Description

Beetroot juice is a dietary supplement with good evidence for improving sports performance in different sport contexts, however, the evidence about the effects of beetroot juice in jump capacity is unclear. Therefore a deeper knowledge about the effects of beetroot juice on several components of vertical jump performance remain largely unexplored between we can mention phase duration peak power, average power, peak velocity, initial force, and peak force. Thus, the aim of this study was to conduct a comprehensive examination of beetroot juice effects on several countermovement jump components.
