Study Design
Researchers assessed 55 athletes from the National Wheelchair Basketball Association during three 20-meter sprints and three change-of-direction efforts. Inertial sensors recorded movement during selected pushes representing acceleration, transition and higher-speed maintenance. Participants were also grouped using a functional classification scale ranging from 1.0 to 4.5, with larger values denoting greater function.
Straight-Line Sprint Findings
In the 20-meter efforts, faster times were associated with backward trunk movement during the opening push and a longer right-side push later in the sprint. Years of collegiate experience also contributed to the performance model. Together, these factors accounted for more than 40% of the variation in sprint times, according to the study summary.
Directional Change And Interpretation
For change-of-direction sprints, movement of the shoulder opposite the pivot during the third push was the strongest performance predictor. Classification did not show an association with sprint outcomes, which the researchers said may indicate athletes use different compensatory movement patterns to reach similar competitive speeds. The findings point to phase-specific coaching priorities, rather than one universal technique.
