Shoulder biomechanics of para-table tennis: a case study of a standing class para-athlete with severe leg impairment.

July 2022
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.
Article Synopsis
- The study examined the biomechanics of para-table tennis players by comparing the shoulder, elbow, and wrist movements of able-bodied (AB) and wheelchair players across different disability classifications.
- Nineteen participants—including AB players and para-players from various classifications—performed topspin drives while their joint movements were measured using advanced sensors.
- Results indicated significant differences in upper limb motion between AB and wheelchair players, with specific variations in technique among different disability classes, suggesting the need for tailored training programs for para-players to accommodate their unique movement strategies and physical challenges.
The aim of this study was to analyse the front-crawl arm-pull kinetics and kinematics, comparing it before and after post-activation potentiation (PAP), and the associations between variables describing of the arm-pull kinetics. Twelve male competitive swimmers were randomly assigned to perform two different warm-ups in a crossover manner: (i) non-PAP (control condition); and (ii) PAP (experimental condition). PAP consisted of 2 × 5 arm-pulls with resistance bands by both upper-limbs.
