Study design
Athletes completed standardized sprint, turning, stop-go and complex-skill tests using wheel- and trunk-mounted inertial sensors. Researchers compared these results with speed and rotational measures derived from full-match sensor data, assessing correlations, agreement and group differences.
Strongest test-match links
The 20-metre sprint showed a strong association with maximal forward match speed, with a small bias. An isolated 180-degree turn best represented rotational capacity. Acceleration measures correlated moderately but showed poor absolute agreement, suggesting they indicate maximal capacity rather than match-equivalent output.
Impairment-related patterns
Tests more closely matched match behavior among athletes with coordination impairment. For athletes without coordination impairment, testing tended to underestimate match speed and overestimate acceleration. Trunk-sensor outcomes also differed substantially between groups, while classification was positively associated with performance at similar strength across groups.
