“…These additional 5 cm would provide players, if they elect to position the top of the cushion at a height of 63 cm in comparison to 58 cm from the floor (International Wheelchair Basketball Federation [IWBF], 2014b), with a potential advantage when being defended in the act of shooting or rebounding. Santos et al (2014) highlighted the importance of trunk stability and movement when completing faster movement directions in the forward plane when rebounding. van der Slikke et al (2016) also noted that international players average seat height is significantly higher to enable players to achieve greater upward reach.…”

Making Every “Point” Count: Identifying the Key Determinants of Team Success in Elite Men’s Wheelchair Basketball

Wheelchair basketball coaches and researchers have typically relied on box score data and the Comprehensive Basketball Grading System to inform practice, however, these data do not acknowledge how the dynamic perspectives of teams change, vary and adapt during possessions in relation to the outcome of a game. Therefore, this study aimed to identify the key dynamic variables associated with team success in elite men’s wheelchair basketball and explore the impact of each key dynamic variable upon the outcome of performance through the use of binary logistic regression modeling. The valid and reliable template developed Francis et al. (2019) was used to analyze video footage in SportsCode from 31 games at the men’s 2015 European Wheelchair Basketball Championships. The 31 games resulted in 6,126 rows of data which were exported and converted into a CSV file, analyzed using R ( R Core Team, 2015 ) and subjected to a data modeling process. Chi-square analyses identified significant ( p < 0.05) relationships between Game Outcome and 19 Categorical Predictor Variables. Automated stepwise binary regression model building was completed using 70% of the data (4,282 possessions) and produced a model that included 12 Categorical Predictor Variables. The accuracy of the developed model was deemed to be acceptable at accurately predicting the remaining 30% of the data (1,844 possessions) and produced an area under the receiver operating characteristic curve value of 0.759. The model identified the odds of winning are more than double when the team in possession are in a state of winning at the start of the possession are increased five-fold when the offensive team do not use a 1.0 or 1.5 classified player, but are increased six-fold when the offensive team use three or more 3.0 or 3.5 players. The final model can be used by coaches, players and support staff to devise training and game strategies that involve selecting the most appropriate offensive and defensive approaches when performing ball possessions to enhance the likelihood of winning in elite men’s wheelchair basketball.

“…Furthermore, the forces propagated along the entire body, when the trunk is stabilized, could convey distally into the limbs, assisting them into any motor task. 26 These concepts could explain how a better trunk stabilization, both actively or passively, helps WB players to improve the performance in action such as maneuver the wheelchair or perform the athletic gesture (dribble, pass, or shoot) in the most efficient way. After these considerations, figure 8 and figure 8 with ball test (test 2 and 3) improvements could be addressed to the strap contribution in trunk stabilization.…”

Background: Wheelchair basketball (WB) represents a great physical activity, rehabilitation, and integration opportunity for people with disability. Straps are wheelchair accessories used to ensure safeness and stability. Nevertheless, some athletes report feeling limited in movements because of these restraint devices. The aim of this study was thus to deepen whether straps could affect performance and cardiorespiratory effort in WB players' athletic gesture and furthermore whether sport performance could be influenced by experience, anthropometric features, or classification score. Methods: Ten WB elite athletes were enrolled in this observational cross-sectional study. Speediness, wheelchair maneuverability, and sport-specific skills were evaluated with 3 tests: 20-m straight line test (test 1), figure 8 test (test 2), and figure 8 with ball test (test 3); all tests were performed with and without straps. Cardiorespiratory parameters (blood pressure [BP], heart rate, and oxygen saturation) were registered before and after tests. Anthropometric data, classification score, and practice’s years were collected and compared with test results. Results: Performance significantly improved in all tests wearing straps (test 1 P = 0.007, test 2 P = 0.009, and test 3 P = 0.025). No significant variation in cardiorespiratory basic signs emerged before and after the tests, with or without straps (systolic BP P = 0.140, diastolic BP P = 0.564, heart rate P = 0.066, and oxygen saturation P = 0.564). A statistically significant relation between test 1 with straps and classification score (coefficient = −0.25; P = 0.008) and test 3 without straps and classification score (coefficient = 1.00; P = 0.032) was found. No further relations emerged between test results and anthropometric data, classification score, and practice’s years (P > 0.05). Conclusions: These findings demonstrated that straps, as well as ensuring safety and preventing injuries, also improve the WB performance, stabilizing the trunk and implementing upper limb skills, without exposing players to excessive cardiorespiratory and biomechanical stresses.

“…The musculature of the trunk and upper limbs plays a vital role in wheelchair basketball [40][41][42]. In games, athletes are constrained in wheelchairs and perform complex wheelchair maneuvers, such as propelling, stopping, and changing direction quickly and repeatedly; additionally, technical ball skills (such as dribbling, passing, and shooting) are required.…”

Studies on the effects of training confinement on athletes with physical impairments are limited. Hence, in this retrospective cohort study, we aimed to investigate the impact of prolonged cessation of organized team training due to the coronavirus disease 2019 pandemic on the body composition of elite female Japanese basketball athletes. Fourteen female wheelchair basketball athletes (aged ≥20 years) were enrolled. The primary outcomes were lean and adipose indices measured using whole-body dual-energy X-ray absorptiometry. The impact of prolonged organized team training cessation on body composition was investigated by comparing the body composition at baseline and post-training confinement. A reduced whole-body lean mass (p = 0.038) and percent lean mass (p = 0.022), as well as an increased percent body fat (p = 0.035), were observed after the confinement period. The regional analysis revealed reduced percent lean and increased percent fat masses in the trunk (p = 0.015 and p = 0.026, respectively) and upper limbs (p = 0.036 and p = 0.048, respectively). In conclusion, prolonged organized team training cessation reduced lean mass and increased body fat percentage, primarily in the trunk and upper limbs. Individualized training programs targeting these body regions should be implemented to improve body composition and physical conditions in athletes during and after prolonged cessation of organized team training.
