VBSPT Application of basketball measurement for adolescent

Abstract

Van Basketball Skill and Performance Test (VBSPT) is designed to assist basketball athletes and basketball coaches in assessing their performance based on the test results and adhering to the training guidelines derived from the application's recommendations. The development goal of the VBSPT is to directly view their performance statistics based on the test results, which will benefit not only basketball coaches but also physical education teachers. These apps are designed to operate on smartphones and tablets; the adaptive applied software undergoes continuous enhancements and serves as the central component of the computer. The two elements (15 items) of the web-based application of the van basketball skill and performance test (VBSPT) were evaluated by a group of 10 experts. The study involved the participation of five experts in information technology and five basketball coach experts. The Delphi approach and test-retest methods were employed for data collection, while Aiken's formula, intraclass correlation coefficients (ICC), and Cronbach's alpha were utilized for data analysis. The expert assessment technique indicates that the content validity of the aspect is good, as evidenced by the results with a value of 0.80. The reliability of each feature of the basketball skill and performance test instrument was assessed using Cronbach's alpha, yielding a coefficient of 0.723. The ICC score agreement between raters is 0.723, with a consistency of 0.148 for one rater. Based on the results, the reliability and usability standards were met. VBSPT is a valuable tool for checking a web-based application's technical quality and usability. Key words: web-based, application, basketball, adolescent
