Design validity of interval and plyometric training programs for simultaneous increases in VO2 max, reactive agility, power in basketball: Aiken validity

Abstract

The purpose of this study was to test the content validity of the design in interval training and plyometrics to simultaneously increase VO2 max, reactive agility, and power. The population of the study were basketball athletes from the Special Region of Yogyakarta aged 13-18 years with 40 athletes as research sample. The sample was obtained through random sampling technique. The research subjects used 7 experts and the data collection used the Delphi technique. Data analysis employed Aiken's V formula. The results of data analysis show that the coefficient of Aiken's V is above 0.80, so that all aspects of the design of the plyometric training program and interval training program can be said to be valid. Thus, the results of the study can be concluded that the design of interval and plyometric training programs for increasing VO2 max, reactive agility, and power in basketball has sufficient content validity with Aiken.
