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 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.

AbstractIn the German National Wheelchair Basketball League, men and women play together. On the national teams, on the other hand, they play separately according to gender. In addition, people without disabilities can also participate in wheelchair basketball. The differences in terms of disability and gender are to be classified and, if possible, eliminated in the competition with a classification system. The intersectional analysis of 12 biographical interviews with current national team players shows a clear reproduction of a traditional gender order. The women report various hierarchical relationships on the playing field that are obviously based on gender. Men play in more important positions and are considered more efficient. Yet these phenomena are mostly taken for granted and hardly questioned. Likewise, certain characteristics are attributed and certain roles are assigned to female players based on their gender. The men interviewed do not see these phenomena or do not reflect on them critically. The difference category of disability also has an influence on the competition setting and the gender discrimination.

Problem: Little is known about health complaints and their prevention in elite wheelchair basketball. The study aimed to survey training environment and health complaints of elite wheelchair basketball players in the 12 months prior to the Wheelchair Basketball World Championships 2018 (WBWC). Methods: Players answered an anonymous retrospective questionnaire on match and training exposure, daily training environment, injury prevention as well as health problems and their implications in the 12 months before the WBWC. Results: In the 12 months prior the WBWC, 46.2% of athletes struggled at least sometimes with physical complaints, and 15.9% played often/always with pain or health complaints. Half of the players (50.8%) did not modify the volume of their training when having health complaints. Sixty percent of the athletes reported that injury prevention exercises were often or always part of their training. The overall training environment and national team support was rated as good or very good by 89.7% and 69.1% of players, respectively. Discussion: Prior to the world championships, wheelchair basketball players reported a high rate of pre-competition health complaints despite good training environment and the use of preventive strategies. Most players indicated they continued to play with pain and health complaints. Frequently playing with health complaints is known from other Olympic sports or pedestrian basketball. Prospective surveillance systems are needed to identify health complaints early and to examine efficiency of preventive measures in order to improve health and probably performance of wheelchair basketball players.

This study aimed to investigate the association between the optimum power load in the bench press (BP), shoulder press (SP), and prone bench pull (PBP) exercises and acceleration (ACC) and speed performances in 11 National Team wheelchair basketball (WB) players with similar levels of disability. All athletes were previously familiarized with the testing procedures that were performed on the same day during the competitive period of the season. First, athletes performed a wheelchair 20-m sprint assessment and, subsequently, a maximum power load test to determine the mean propulsive power (MPP) in the BP, SP, and PBP. A Pearson product–moment correlation was used to examine the relationships between sprint velocity (VEL), ACC, and the MPP in the three exercises. The significance level was set as p < .05. Large to very large significant associations were observed between VEL and ACC and the MPP in the BP, SP, and PBP exercises (r varying from .60 to .77; p < .05). The results reveal that WB players who produce more power in these three exercises are also able to accelerate faster and achieve higher speeds over short distances. Given the key importance of high and successive ACCs during wheelchair game-related maneuvers, it is recommended that coaches frequently assess the optimum power load in BP, SP, and PBP in WB players, even during their regular training sessions.
