Environment And Health

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.

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.

Background Female athletes have a higher risk of anterior cruciate ligament injury than their male counterparts who play at similar levels in sports involving pivoting and landing. Hypothesis The competitive female basketball players who participated in a sports injury prevention training program would show better muscle strength and flexibility and improved biomechanical properties associated with anterior cruciate ligament injury than during the pretraining period and than posttraining parameters in a control group. Study Design Controlled laboratory study. Methods A total of 22 high school female basketball players were recruited and randomly divided into 2 groups (the experimental group and the control group, 11 participants each). The experimental group was instructed in the 6 parts of the sports injury prevention training program and performed it during the first 20 minutes of team practice for the next 8 weeks, while the control group performed their regular training program. Both groups were tested with a rebound-jump task before and after the 8-week period. A total of 21 reflective markers were placed in preassigned positions. In this controlled laboratory study, a 2-way analysis of variance (2 × 2) experimental design was used for the statistical analysis (P < .05) using the experimental group and a testing session as within and between factors, respectively. Post hoc tests with Sidak correction were used when significant factor effects and/or interactions were observed. Results A comparison of the experimental group's pretraining and posttraining results identified training effects on all strength parameters (P = .004 to .043) and on knee flexion, which reflects increased flexibility (P = .022). The experimental group showed higher knee flexion angles (P = .024), greater interknee distances (P = .004), lower hamstring-quadriceps ratios (P = .023), and lower maximum knee extension torques (P = .043) after training. In the control group, no statistical differences were observed between pretraining and posttraining findings (P = .084 to .873). At pretraining, no significant differences were observed between the 2 groups for any parameter (P = .067 to .784). However, a comparison of the 2 groups after training revealed that the experimental group had significantly higher knee flexion angles (P = .023), greater knee distances (P = .005), lower hamstring-quadriceps ratios (P = .021), lower maximum knee extension torques (P = .124), and higher maximum knee abduction torques (P = .043) than the control group. Conclusion The sports injury prevention training program improved the strength and flexibility of the competitive female basketball players tested and biomechanical properties associated with anterior cruciate ligament injury as compared with pretraining parameters and with posttraining parameters in the control group. Clinical Relevance This injury prevention program could potentially modify the flexibility, strength, and biomechanical properties associated with ACL injury and lower the athlete's risk for injury.

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.

The application of new technologies in wheelchair basketball (WB) is important for the advancement and improvement of athletic performance. The purposes of this study are twofold: (a) to develop a methodological design in order to assess WB players’ performance, using wireless inertial measurement units (WIMU®) and a laser system (BioLaserSport® with computer vision), in a 20 m sprint test on court and (b) to assess bilateral symmetry as a performance indicator and for injury prevention purposes, the study of which in previous research is unknown. For both aims, the relation of the acceleration of the players’ wrists to the speed achieved by the player in the wheelchair was explored. Ten elite WB players participated in an on-court 20 m sprint test during real training. BioLaserSport® with computer vision was used to assess the average velocity (Va) and maximum velocity (Vmax) of the WB players, and two WIMU® were used for the total acceleration (AcelT) of the players’ wrists. A very high correlation was obtained in the assessment of the Va (0.97) and AcelT of both wrists (0.90 and 0.85). There was a significant relationship between the average AcelT of the dominant wrist and the Va on-court sprint velocity (p < 0.05). Two players did not show good wrist symmetry. In conclusion, a new methodological protocol was developed, making it possible to assess the bilateral symmetries in elite WB players in on-court real training and the relation between the acceleration of players’ wrists and players’ wheelchair speed. Coaches can use this protocol to assess performance or for injury prevention, as it shows very good reliability, with high ICC values.

And Gender

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.
