“…Unsurprisingly, a number of studies [4,6,34,35] have indicated that many kinematic and kinetic measures increase with speed. For example, Wang, Vrongistinos, & Xu [34] found that over consecutive pushes during wheelchair sprinting, higher range of motion values occurred around the shoulder and elbow leading to greater maximum angular velocity of the upper arm and forearm and an increased range of motion over which angular acceleration could be produced.…”

In comparing the speed and stroke cycle characteristics during the 100 m wheelchair race, Chow [35] also found significant differences in stroke speed, length, push and recovery times at different portions of the race. At a faster speed, Boninger et al [4] found that the elbow range of motion and peak acceleration in shoulder sagittal flexion and extension, abduction and adduction all increased.…”

Constraints influencing sports wheelchair propulsion performance and injury risk

The Paralympic Games are the pinnacle of sport for many athletes with a disability. A potential issue for many wheelchair athletes is how to train hard to maximise performance while also reducing the risk of injuries, particularly to the shoulder due to the accumulation of stress placed on this joint during activities of daily living, training and competition. The overall purpose of this narrative review was to use the constraints-led approach of dynamical systems theory to examine how various constraints acting upon the wheelchair-user interface may alter hand rim wheelchair performance during sporting activities, and to a lesser extent, their injury risk. As we found no studies involving Paralympic athletes that have directly utilised the dynamical systems approach to interpret their data, we have used this approach to select some potential constraints and discussed how they may alter wheelchair performance and/or injury risk. Organism constraints examined included player classifications, wheelchair setup, training and intrinsic injury risk factors. Task constraints examined the influence of velocity and types of locomotion (court sports vs racing) in wheelchair propulsion, while environmental constraints focused on forces that tend to oppose motion such as friction and surface inclination. Finally, the ecological validity of the research studies assessing wheelchair propulsion was critiqued prior to recommendations for practice and future research being given.

“…Players were analysed during the first 6 min of play and the data were extrapolated to the rest of the game. Kinematic analysis has been also used to study wheelchair propulsion, taking into account timing parameters, speed, stroke length and frequency, and head, trunk, shoulder, elbow and wrist kinematics, mainly in wheelchair races (Chow & Chae, 2007;Vanlandewijck, Theisen, & Daly, 2001).…”

The kinematics of male wheelchair rugby players (n = 8) during the final match of the 2008 Demolition Derby were assessed using two cameras (10 Hz) and a tracking method based on image-processing techniques. The players' on-court trajectory, total and accumulated distances covered, distances covered during working and stopped game clock, and average velocity were calculated. The players covered 2294.7 +/- 391.5 m in the first half and 2245.4 +/- 431.5 m in the second half. The average velocity was 14.5% greater in the first (1.22 +/- 0.21 m . s(-1)) than in the second half (1.05 +/- 0.20 m . s(-1)). The reduction in velocity was most marked in players with less functional capacity. The working game clock represented 48% of total game time (32 of 66.8 minutes) and the distance covered by all players during working game clock was 60% of the overall distance covered during the whole game (36,323 m). The results provide new information regarding the dynamics of a wheelchair rugby match and should aid coaches in planning effective training and coaching strategies.

“…Stroke length is the difference between the contact distance of a stroke and the contact covered distance of the next stroke. Thus, stroke length can be explained as the covered distance with handrim contact in one stroke [14]. The average speed is calculated dividing the stroke length by the stroke frequency [14].…”

Numeriθal simulations have provided useful evidenθe in helping several sportsmen to exθel in their field. This methodology aims to have a deeper understanding on the influenθe of equipment and sports teθhniques on sports performanθe. In wheelθhair raθing, teθhnology was used without θonsidering speθifiθ sport some of the Paralympiθ sports used the same teθhnology of their Olympiθ θounterparts . It has induθed unique θhanges in prosthetiθ and wheelθhair deviθes. Eventually, teθhnology has ηeθome an essential part of Paralympiθ sports, wheelθhair-raθing ηeing one of the most popular events. Numeriθal simulations θan help us gather evidenθe on the effeθts of drag forθe aθting upon the athlete-θhair system.
