Effects of Maximum Strength and Acceleration Ability on Performance and Training in Wheelchair Sports (OPM)

August 5, 2024 updated by: Swiss Paraplegic Research, Nottwil

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.

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
maximal pull force
Time Frame: during 1 second of maximal pulling
The maximal isometric force produced during pulling in the sport wheelchair
during 1 second of maximal pulling

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
maximal push force
Time Frame: during the first second of maximal pushing
The maximal isometric force produced during pushing in the sport wheelchair
during the first second of maximal pushing
maximal acceleration
Time Frame: during the first second of acceleration
The maximal acceleration reached with one push in the sport wheelchair
during the first second of acceleration
sprint time
Time Frame: during the last second of the 20 metre sprint
The time for the linear sprint over 20m in the sport wheelchair
during the last second of the 20 metre sprint

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
rate of force development
Time Frame: during the first second of maximal push
The rate of force development (RFD) in the isometric push and pull test
during the first second of maximal push
sprint distance time
Time Frame: during 5 seconds of the linear sprint
The time for the linear sprint over sub distance in the sport wheelchair
during 5 seconds of the linear sprint
one push maximal speed
Time Frame: during the last second of acceleration
The maximal speed reached with one push in the sport wheelchair
during the last second of acceleration
