The Effect od Beetroot Juice on Forearm Muscle Strength and Muscle EMG Activity After BloodFlow Restriction

Not Applicable

• Conditions: Muscle Strength
• Interventions: Dietary Supplement: Placebo; Dietary Supplement: Beetroot juice

• Registration Number: NCT06227091
• Lead Sponsor: Poznan University of Physical Education

Brief Summary

The primary aim of the current study is determine the effect of beetroot juice consumption on maximal grip strength and EMG muscle activity

Detailed Description

In random order subjects will consume high nitrate beetroot juice or low level of nitrate beetroot juice. Grip strength and EMG will be measured at the beginning and repeated after 2h.

Using blood pressure cuff, occlusion will be induced to restrict blood flow in the brachial artery. Following the deflation of the cuff, assessments will be conducted for grip strength and electromyography (EMG) activation of the forearm muscles. These measurements will be taken both initially and after a 2-hour interval.
