Relationship between aerobic and anaerobic parameters and functional classification in wheelchair basketball players

Background and objectives: Wheelchair basketball players are classified into four functional classes according to the player’s “volume of action”, characterized by trunk movement and stability. As this classification is based on a kinematic point of view, test items might be differentially affected by the functional classification level. We aimed to clarify field-based skill test items closely related to the functional classification level. Materials and Methods: Twenty-six female wheelchair basketball athletes (Japan National Team candidates) completed seven field-based skill tests (20 m sprint, agility T-test, figure-eight with a ball test, the Yo-Yo 10 m recovery test, and three types of maximal passes), and anthropometric measurements were applied. Results: Significant differences among the classification levels were found for one-hand maximal passes (baseball and hook passes) and the figure-eight with a ball test. Furthermore, performance in the 20 m sprint and 10 m Yo-Yo recovery tests significantly differed between classes 1 and 4. Conclusions: The test items most influenced by the classification levels were one-hand passes, which require trunk stability and balance not only in the horizontal plane, but also in the sagittal and frontal planes. Coaches should consider which test items are strongly affected by the functional classification level when assessing a player’s performance.

The purpose of this study was to examine the physiological changes in elite wheelchair basketball players leading up to the 2000 Paralympics. Twelve male players attended regular physiological assessments on six occasions; averaged data of two sessions for each year were used. Physiological measures included body mass, skinfold measurements, peak oxygen uptake and peak power obtained during maximal sprinting. VO2peak significantly increased from 2.65 to 2.83 L·min-1 prior to the Paralympics. Training had little influence on the anthropometric measurements or maximal sprinting data. In conclusion, the GB wheelchair basketball players appeared to have high levels of aerobic and anaerobic fitness. The longitudinal physiological profiles leading to the 2000 Paralympics suggest that players improved their aerobic base while maintaining other fitness prerequisites.

The purpose of this study was to develop a methodology to accurately analyze sprint performance of elite wheelchair basketball (WB) players in their own training context using a laser system and to analyze the velocity curve performed by the players regarding their functional classification and their playing position. Twelve WB players, from the Spanish men’s national team, took part in an oncourt 20-m-sprint test. BioLaserSport® was used to obtain time, mean velocities (Vm), maximum velocities (Vmax), and distances at 90%, 95%, and 98% of their Vmax. Vm and Vmax reached high values in Classes II and III and in the guard playing position. The protocol developed with the laser system makes it possible to obtain a precise velocity curve in short sprints and allows easy analysis of decisive kinematic performance variables in WB players, showing immediate feedback to coaches and players. The normalized data allow an interpretation of how much, where, and when Vmax occurs along the test.

Objective:To compare classification levels and trunk stabilization of wheelchair basketball players and to identify their norm values of trunk balance.Participants:113 wheelchair basketball players in the super and first Turkish leagues.Interventions:A modified Wheelchair Skills Test (WST) (version 4.1) was used to evaluate trunk stabilization. Two skills were chosen that correspond to the stationary wheelie activity in WST, the 30-s stationary wheelie and stationary wheelie in 180°.Main Outcome Measure:There are no statistical differences between WST rates and point means.Results:The skills and success and safety rates of the players with 1.5 points (51.9%, 44.4%) were lower than those of the players with 1.0 point (70%, 66.7%). In players with 2.5 and 2.0 points, the most successful and safest percentage values were 78.6%, 78.6% and 82.1%, 75%.Conclusions:Although it is expected that trunk stabilization would be better in players with high points, in our study we encountered conflicting results between the points and sitting balance or trunk stabilization. Our study supports the studies in the literature suggesting modifications in the functional-classification system.
