Weightlifting Belts and Wrist Straps for Weightlifters

Not Applicable

Completed

• Conditions: Exercise Movement Techniques
• Interventions: Device: Weightlifting belts and wrist straps

• Registration Number: NCT05178394
• Lead Sponsor: The University of Hong Kong

Brief Summary

Objective: This study examined the effects of weightlifting belts and wrist straps on the kinematics of the deadlift exercise, time to complete a deadlift and rating of perceived exertion (RPE) in male recreational weightlifters.

Methods: Twenty participants used various combinations of belt and straps during a conventional deadlift. The hip and knee flexion, cervical lordosis, thoracic kyphosis and lumbar lordosis angles and time to complete a deadlift were measured using video analysis software. RPE was also recorded.
