Weightlifting Belts and Wrist Straps for Weightlifters

Study Overview
=================
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Male recreational weightlifters<br> | Device: Weightlifting belts and wrist straps<br>* The participants wore a weightlifting belt (Heavywear Nylon Contour Belt H9, North Carolina, USA) for the with weightlifting belt conditions and/or put on a pair of wrist straps (Versa Gripps Professional Series, Versa Gripps, Maine, USA) for the with wrist strap conditions. The steps involved in completing a conventional deadlift have been detailed in Holmes.<br>|
