Are technical and timing components in para-badminton classifications different?

Abstract

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 tech-nical 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.
