About this study
Official title: The Influence of Weightlifting Belts and Wrist Straps on Deadlift Kinematics, Time to Complete a Deadlift and Rating of Perceived Exertion in Male Recreational Weightlifters
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Weightlifting belts and wrist strapsDevice
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.

Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 5 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hip flexion angle (time frame: Through study completion, an average of two hours). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jan 2022.
