Aim Develop field-based mobility test to quantify mobility performance and optimize
Wheelchair basketball Game performance
ATHLETE PERFORMANCE Mobility performance
Physical performance
Methods 27 Dutch national athletes 29 International athletes
Video analysis Most common activities: Driving forward; 45% of time Rotation; 29% of time Standing still; 19% of time
Video analysis
Field-based mobility test 15 activities in 1 test-circuit Separate activities
• Sprint 12m • Rotation left/right (radius 1.9m) • Turn on the spot (left/right)
Combined activities
• Sprint interval 4 x 3m • Rotation interval left/right (90°-90°-180°) • Turn on the spot interval left/right (90 °-90 °) • 12 m sprint, turn, 12 m slalom, turn
Specific skills Interview experts Practical requirements: Test on the same floor surface Work-to-rest ratio
Interview experts (e.g. coaches and athletes) Inertial sensors
Inertial sensors Most common travel stretch: 3 meter driving forward Maximal distance: 12 meter Most frequent turn radius: Radius 1.5-2.5 meter
Influence ball possession
Entire wheelchair basketball matches
Video analysis
Results
• Block-actions
Ball possession
• Sprint 12 m • Rotation left/right (radius 1.9m)
Future
Test will be performed on national and international standard to test validity, sensitivity and reliability.
