ANALYSIS OF BORHYTHM ATHLETES IN BADMINTON AT THE 2021 YUZU ISOTONIC AKMIL OPEN CHAMPIONSHIP

Abstract

Biorhythms are a human biological cycle consisting of primary rhythms, secondary rhythms and extra rhythms. This biological cycle is very important in performance or sports, because it includes physical and psychological aspects. Badminton as a sport requires good physical and psychological abilities to make fast and precise movements. Badminton is a sport that demands excellent physical condition. The aim of this research is to find out 1) whether there are differences in the primary rhythm aspects of the 1st place and 2nd place badminton athletes participating in the 2021 Yuzu Isotonic Akmil Open championship?, 2) whether there are differences in the secondary rhythm aspects of the 1st place and 2nd place badminton athletes participating in the Yuzu Isotonic Akmil championship Open 2021?, 3) is there a difference in the extra rhythm aspect of the 1st place and 2nd place badminton athletes participating in the 2021 Yuzu Isotonic Akmil Open championship?, and 4) is there a difference in the biorhythm aspect of the 1st place and 2nd place badminton athletes participating in the 2021 Yuzu Isotonic Akmil Open championship? This research is experimental research with a one shot study approach. The instrument used in this research is natural biological software. Biorhythm software can calculate and predict an individual's energy levels, physical strength, emotions, and intellect. The population is badminton players participating in the Yuzu Isotonic Akmil Open 2021 championship, the sampling technique uses purposive. Data analysis used the t test with a significance level of 5%. The results of the research show that: 1) there is a significant difference in the primary rhythm aspect of the 1st place and 2nd place badminton athletes, 2) there is a significant difference in the secondary rhythm aspect of the 1st place and 2nd place badminton athlete, 3) there is a significant difference in the rhythm aspect extra 1st place and 2nd place badminton athletes, and 4) there are significant differences in the biorhythmic aspects of the 1st place and 2nd place badminton athletes participating in the 2021 Yuzu Isotonic Akmil Open Championship. Based on the research results are advised: 1) badminton coaches to deepen and understand aspects of athletes' biorhythms in training and competitions, 2) The other researchers use natural biorhythm software in other sports, both individual and team sports.
