“…As previous research has described, changes to wheelchair set-up cause alterations to the propulsion approach [9,10]. This is supported by Figure 2, where there are visible differences in the ContAng and RelAng for Player 3 when changing important set-up parameters, including increases to RelAngs when reducing SA.…”

“…Once the player was comfortable in the set-up, they then completed two 5 m sprints from a stationary position initiated in their own time. This test focused on the ability to accelerate from standstill, previously identified as a crucial factor for performance [4,10], and the resultant kinematic changes. Time to complete each test was monitored using laser timing gates (Kinematic Measurement System, Fitness Technology, Australia), with players given sufficient break between tests to minimise any effects of fatigue.…”

“…Depending on capabilities of the player, including amount of trunk function, varying levels of pushrim access are possible with the same seat height. Similar trade-off effects exist for most parameters; e.g., seat depth-a deeper seat position can improve stability but limit agility [10]; seat angle-an increase provides greater stability, but limits trunk mobility and therefore acceleration from standstill [4]. Other factors, such as tyre pressure, have also been suggested to influence performance due to the effects on tyre grip and wheel spin, although this has yet to be investigated.…”

Abstract:Optimisation of wheelchairs for court sports is currently a difficult and time-consuming process due to the broad range of impairments across athletes, difficulties in monitoring on-court performance, and the trade-off set-up that parameters have on key performance variables. A robust design approach to this problem can potentially reduce the amount of testing required, and therefore allow for individual on-court assessments. This study used orthogonal design with four set-up factors (seat height, depth, and angle, as well as tyre pressure) at three levels (current, decreased, and increased) for three elite wheelchair rugby players. Each player performed two maximal effort sprints from a stationary position in nine different set-ups, with this allowing for detailed analysis of each factor and level. Whilst statistical significance is difficult to obtain due to the small sample size, meaningful difference results aligning with previous research findings were identified and provide support for the use of this approach.

“…Thus, mobility performance is not only dependent on physical athlete characteristics like strength, power and aerobic capacity, but also on the interface between athlete and wheelchair. In mobility performance, key determinants are the ability to accelerate, sprint, brake or rotate [1][2][3] . 4 recently developed and validated a wheelchair mobility performance test (WMP test) for the assessment of mobility performance in wheelchair basketball players.…”

OBJECTIVE: This study aimed to investigate which characteristics of athlete, wheelchair and athlete-wheelchair interface are the best predictors of wheelchair basketball mobility performance. DESIGN: Sixty experienced wheelchair basketball players performed a wheelchair mobility performance test to assess their mobility performance. To determine which variables were the best predictors of mobility performance, forward stepwise linear regression analyses were performed on a set of 33 characteristics, including ten athlete, nineteen wheelchair and four athlete-wheelchair interface characteristics. RESULTS: Eight of the characteristics turned out to be significant predictors of wheelchair basketball mobility performance. Classification, experience, maximal isometric force, wheel axis height and hand rim diameter -which both interchangeable with each other and wheel diameter -camber angle, and the vertical distance between shoulder and rear wheel axis -which was interchangeable with seat height -were positively associated with mobility performance. The vertical distance between the front seat and the footrest was negatively associated with mobility performance. CONCLUSION:With this insight, coaches and biomechanical specialists are provided with statistical findings to determine which characteristics they could focus on best to improve mobility performance. Six out of eight predictors are modifiable and can be optimized to improve mobility performance. These adjustments could be carried out both in training (maximal isometric force) and in wheelchair configurations (e.g. camber angle).

“…6,18 For wheelchair athletes, trunk balance is crucial for movement and the performance analysis of the trunk with respect to postural balance is a basic parameter for functional evaluation. 19 If we consider that the disabled individual has significant changes in orthopedic functionality because of a reduction of balance due to loss of proprioceptive and neuromuscular sensory feedback from trauma-based SCI, 20,21 then the measuring of components that are part of the functionality of practicing basketball surely contribute to the advancement of sport and performance for the athlete.…”

OBJECTIVE: Postural control of the trunk is important to stabilize the entire body and to generate muscle force during sports activities. When the trunk is stable, it is easier and safer to transfer applied forces along the body to perform any motor task because it enhances muscle action and reduces joint loads. Postural control of the trunk is important to stabilize the entire body and to generate muscle force during sports activities. The aim of this study is to verify the velocity and direction of trunk movement in wheelchair basketball athletes. METHOD: Participants were 26 wheelchair basketball athletes, they were tested on the NeuroCom Balance Master System, protocol: Rhythmic Weight Shift. They were asked to sway the entire body to the right, left, forward and backward. Trials evaluated these movements in low, medium and high velocities. RESULT: Movement velocity was very significantly affected by task speed and task direction. The highest movement velocity was observed for the fast task and for the left/right direction. There was no interaction between the task and its direction. CONCLUSION: Wheelchair basketball athletes moved their body faster in the left/right direction. This result suggests that postural control is direction-dependent for the wheelchair-bound individual.
