“…The area at the front of the court is the most vulnerable part, and it relates to the offensive game strategy (Phomsoupha & Laffaye, 2015;Strapasson et al, 2017;Ribeiro & Almeida, 2020). The decision to use this strategy in PBd can be explained by the difficulty in reaching the shuttle due to the sitting position and the players' trunk flexion difficulties, common in wheelchair players (Beckman et al, 2017;Zemková, Muyor & Jeleň, 2018).…”

Considering the smaller number of studies investigating Para-Badminton (PBd) and the need to understand the technical, tactical and functional classes, the purpose of this research is to investigate the frequency of technical components and timing characteristics in the PBd categories of WH1(Wheelchair/severe impairment) and WH2 (Wheelchair/minor impairment) and to compare between classes. Twenty PBd matches were analyzed in the men's individual category at the 11th World PBd Championship. The mean playing time of the matches was 1,780 (± 575) s for the WH1 class and 2,012 (± 1,098) s for WH2. The average rally time was 10.2 (± 8.4) min for the WH1 and 12.5 (± 12.5) min for WH2. The mean pause time was 15 (± 10.3) s for the WH1 class and 14.1 (±10.5) s for the WH2. The mean number of shots per game was 552 (±197) and 719 (±480) for class WH1 and WH2 respectively. In both classes: the most frequent shots performed by the players were Clear, Lob, Drop, and Net-shot; the players used backhand more often than the forehand service and the short service compared to the long one; the errors stood out in relation to the winner points. In addition, there was a higher proportion of shots at the front of the court in both classes. It was found that the WH2 class showed a higher intensity (longer rally time and shorter pause time) and a higher frequency of technical actions (higher number of shuttle hits) when compared to the WH1. This information can assist coaches during training to guide the development of the temporal and technical aspects of the PBd, as well as monitor them during matches to obtain victory.

“…The disability of these athletes participating in Paralympic court sports may impact their sporting performance [ 17 ]. For instance, wheelchair table tennis players exhibit lower mobility in the thoracic and lumbar regions of the spine during trunk flexion as well as lower lumbar inversion and pelvic retroversion than able-bodied athletes [ 18 ]. Their decreased posterior concavity and limited range of motion during trunk rotations contribute to lower trunk rotational velocity [ 18 ].…”

While competitive training is usually associated with the prevalence of back pain and injuries in athletes, little attention is being paid to the positive effects of sport-specific exercises on core musculature in the prevention of back problems. This scoping review aims (i) to map the literature that addresses the effects on reduction of back problems following athlete training with differing demands on the core musculature and (ii) to identify gaps in the existing literature and propose future research on this topic. The main literature search was conducted on the MEDLINE, PubMed, Web of Science, Scopus, and Cochrane Library databases and was completed on Elsevier, SpringerLink, and Google Scholar. A total of 21 research articles met the inclusion criteria. The findings of 17 studies identified that core strengthening and core stabilization exercises, alone or in combination with athlete training, contribute to the reduction of back pain in athletes, whereas only four studies revealed no significant association of core muscle strength and/or endurance with back problems. Nevertheless, more research is warranted to elucidate the pros and cons of purely sport-specific training with differing demands on the core musculature on back health in athletes. This could help us to design prevention strategies specifically tailored to individual athletes.

“…The results showed that posterior hip extension and flexion, external knee rotation and anterior hip extension and flexion were significantly greater in the professional athletes compared to the amateur group. Zemková et al [8] explored the relationship between trunk rotation velocity and spinal mobility and curvature in wheelchair table tennis players. The results showed that the trunk rotation velocity and the corresponding angular displacement were significantly lower in wheelchair table tennis players compared to healthy athletes.…”

The technique of backhand topspin against backspin is important for table tennis players to gain more advantages in the confrontation. In this paper, a biomechanical analysis of backhand topspin against backspin was conducted with varsity and non-varsity male table tennis players from Zhejiang Changzheng Vocational and Technical College. The QUAL-ISYS infrared acquisition system collected the changes in the athletes' limb movements, and the force platform collected the changes in the athletes' limb moments in the ball striking process. The results showed that professionally trained athletes were able to achieve greater joint angles and provide greater torques to the shoulder, elbow and wrist joints at the moment of batting. The main purpose of this paper is to provide data reference for the improvement of backhand stroke technique by studying the pattern of limb movements of players when they perform backhand stroke. In summary, in order to improve the backhand technique of hitting backspin, athletes need to focus on training the shoulder, elbow and wrist joints to achieve greater variations of angles and greater torques. The novelty of this paper is collecting the body movements of backhand strokes in a more concise and fast way with the QUALISYS infrared acquisition system.
