Abstract

Paralympic swimmers compete in classes, according to their swimming functional abilities. The classification protocol of physical and technical tests carried out to assign a class has undergone multiple revisions over time, the latest one in 2018. As a consequence, most of the athletes with physical impairment were required to attend an evaluation session to have their class re-assigned. We monitored the impact of this latest revision on the race results in two international Paralympic swimming events which took place prior to and just after the implementation of the classification revisions. Despite no dramatic changes being observed in the overall class performances and in the within-class performance variability, the race times of athletes that had their class changed were significantly more in trend with the mean times of the new classes than with those of the former classes. However, considering class increments/decrements separately, this was the case only for class increments. Further investigations could clarify this result and possibly provide indications for further improvements in the classification system.

Einfluss der Überarbeitung der Welt-Paraschwimm-Klassifikation von 2018 auf die Wettkampfergebnisse bei internationalen paralympischen Schwimmveranstaltungen

Zusammenfassung

Paralympische Schwimmer treten in Startklassen gemäß ihren funktionellen Fähigkeiten beim Schwimmen an. Das Klassifikationsprotokoll der körperlichen und technischen Tests, die bei der Klassenzuweisung Anwendung finden, wurde im Laufe der Zeit vielfach überarbeitet, zuletzt 2018. In der Folge mussten die meisten Athleten mit körperlicher Beeinträchtigung an einer Evaluation teilnehmen, in der ihre Startklasse neu bestimmt wurde. Wir untersuchten den Einfluss der letzten Überarbeitung auf die Wettkampfergebnisse bei zwei internationalen paralympischen Schwimmveranstaltungen, die vor und unmittelbar nach Implementierung der revidierten Klassifikation stattfanden. Obwohl in den Gesamt-Startklassenleistungen und in der Leistungsvariabilität innerhalb von Klassen keine dramatischen Veränderungen zu beobachten waren, lagen die Wettkampfzeiten von Athleten mit Startklassenänderung signifikant stärker im Trend mit den Durchschnittszeiten der neuen Klassen als mit denen der früheren Klassen. Dies war jedoch nur für Klasseninkremente der Fall, wenn Klasseninkremente separat betrachtet wurden. Weiterführende Untersuchungen könnten eine bessere Deutung dieser Ergebnisse ermöglichen und eine Datenbasis für weitere Verbesserungen am Klassifikationssystem schaffen.
