“…The present study is the first to report the shoulder biomechanics of para-table tennis competing while standing to the best of the authors’ knowledge. The findings provide empirical evidence to confirm the previous speculation that para-players would use alternative biomechanics to compensate for their physical impairments [ 10 ]. In the present study, the Class 7 para-player executed both forehand and backhand topspin drives using distinctly different movement patterns than the university team players (Figs.…”

“…Unsurprisingly, standing para-table tennis game characteristics differ from the wheelchair classes [ 2 ]. Despite these para-table tennis players competing while standing in the same way as able-bodied players, it is speculated that para-players use alternative biomechanics compared to their able-bodied counterparts to compensate for their physical impairments [ 10 ]. Currently, no published studies compare the biomechanics of table tennis between standing players with a disability and able-bodied players.…”

Background Both able-bodied and Class 7 para-table tennis players compete while standing, but do they use the same techniques to hit the ball? This case study examined the shoulder joint kinematics of a highly skilled para-table tennis player with severe leg impairment. Methods One international level Class 7 male para-table tennis player was compared with a control group of 9 male, competitive university team players. Participants performed 15 trials of forehand and 15 trials of backhand topspin drives. Shoulder abduction/adduction angles and joint range of motion (ROM) were measured using an inertial measurement system. Results The joint ROM of the para-player was comparable to the control group in the forehand [para-player 38°, controls 32 (15)°] and slightly larger in backhand [para-player 35°, controls 24 (16)°]. Waveform analysis revealed significant differences in the entire forehand drives (p < .001) and the preparation (p < .001) and follow-through phases (p = .014) of the backhand drives. Conclusions Coaches should not simply instruct para-table tennis players to replicate the characteristics of able-bodied players. Depending on the nature of the physical impairment, para-players should optimise their movement strategies for successful performance.

“…The purpose of classi cation is to ensure fair competition under equal conditions for athletes with similar impairments. [20][21][22]. This applies to para table tennis as well, and athletes must be classi ed before competing.…”

“…According to the American Spinal Cord Injury Association (ASIA), the spinal cord injury of these people can be both complete (complete paralysis of the lower limb) and incomplete (the function of the lower limb is not completely lost, but weakened). Based on this, individuals with varying levels of spinal cord injury may be classi ed in this class, leading to unique challenges [20]. The purpose of the present study was to compare the electromyographic variables (EMG activity, onset, and offset) of the muscles involving (deltoid, biceps, erector spinae, external oblique) during the execution of forehand loop and backhand techniques in elite para table tennis players with complete and incomplete spinal cord injuries within class 5.…”

Background Para table tennis is a popular sport among individuals with disabilities, and each Paralympic sport has its own classification system. This classification aims to minimize the impact of impairments caused by disability on athletic performance. In the present study, the electromyographic variables of the muscles involved in performing the forehand loop and backhand techniques of elite para table tennis players with complete and incomplete spinal cord injuries in the class 5 category were compared. Methods In this study, there were 20 male participants at the national level. According to the ASIA scale, the participants were divided into two groups of 10 people. The first group had complete spinal cord injury, while the second group had incomplete spinal cord injury. After they entered the laboratory, the electrodes were connected to their deltoid, biceps, external oblique, and erector spinae muscles. After connecting the electrodes, the tasks were performed and muscles’ EMG activity, as well as their onset and offset contraction were monitored. Results The findings revealed that there are significant differences in the amount of EMG activity as well as the timing of the onset and offset of contraction of selected muscles in two groups of complete and incomplete spinal cord injuries. Conclusion The findings suggest that athletes with incomplete spinal cord injuries may perform better than those in the complete group. However, current para table tennis classification rules place both groups in the same class, which could impact the outcome of matches.

“…According to a 2012 epidemiological study, 17.9% of wheelchair tennis players have injuries [12]. Several recurrent injuries exist in this sport: limb injuries at 72% (tendinopathies, bursitis, ligament, and muscle tension), soft tissue injuries at 30% (blisters, lacerations, abrasions) [13]. However, only one study focused on the impact of the holding of the racket on the risk of injury [11].…”

The objective of this exploratory research is to study the impact of holding a tennis racket while propelling a wheelchair on kinetic and temporal parameters in a field-based environment. 13 experienced wheelchair tennis players with disabilities (36.1 ± 8.2 years, 76.8 ± 15.3 kg, 174.8 ± 17.1 cm) classified between 30/8 and first series performed two 20 m sprints in a straight line, on a tennis court: one while holding a tennis racket and the second without a tennis racket. They used their own sports wheelchair. Potential participants were excluded if they had injuries or pain that impaired propulsion. Maximal total force, maximal propulsive moment, rate of rise, maximal power output, push and cycle times and maximal velocity were measured. Sprinting while holding a tennis racket increased the cycle time by 0,051 s and push time by 0,011s. Sprinting while holding a tennis racket decreased the maximal propulsive moment, maximal power output, rate of rise and maximal velocity during propulsion by 6.713 N/m, 151.108 W, 672.500 N/s and 0.429 m/s, respectively. Our results suggest that the biomechanical changes observed associated with racket propulsion are generally in a direction that would be beneficial for the risk of injury. But sprinting holding a racket seems to decrease players propulsion performance. Working on forward accelerations with a tennis racket would be a line of work for coaches.
