About this study
Official title: Investigation of Maximum Strength and Acceleration Ability as a Function of Grip Position and Its Effects on Performance and Training in Wheelchair Sports
The goal of this observational study is to learn about the relation between grip position and maximal strength and power in wheelchair rugby and basketball athletes. The main question is to investigate the relationship between maximal isometric force, acceleration, and sprint time.
Participants will
- pull in their sport wheelchair against a force transducer
- push in their sport wheelchair from a force transducer
- accelerate as fast as possible with one push
- accelerate as fast as possible over a distance of 20m
Researchers will compare the wheelchair basketball against wheelchair rugby players to see if there is a difference in the parameters.
Read the detailed description
The study duration is approximately 2 hours per participant. First, the screening will be done and the participant does a warmup (~30 min). After that, the participant gets ready for testing, which will last for approximately 90 minutes. In each test, the participants have trial rounds to familiarize with the test procedure. The testing consist of three different exercises, the isometric strength test (IsoMST), the maximum initial push propulsion (MIPP) and the sprint. In the IsoMST a pull setup which was already used in literature and a push setup which has yet to be validated will be used. For the pull setup, the chair of the athlete is fixated on the wall which results in a static situation and allows for an isometric effort. For the push setup, a bumper is installed on the wall, against which the athletes can push with their chair. Different grip position will be measured. In the MIPP test the participants are instructed to accelerate as quickly as possible from standstill with only one push on the rim. The MIPP will be executed with several different grip positions, equal to the IsoMST. For the sprint, 20m will be marked out on a playing court. The athletes are instructed to complete the distance as quickly as possible. Several split times as well as the total time will be measured.

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?
maximal pull force (time frame: during 1 second of maximal pulling). 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.
