Sensor-based Reactive Agility Measurement Tool for Net Game Group Sports: Content Validity

Abstract

It is challenging to develop a measurement of Reactive Agility because the latter is one of the physical components that is highly influenced by internal and external factors. It is thus difficult to perform related measurements due to uncertainties in open game conditions, specifically in the net game group. The purpose of this research is to validate the content of a sensor-based Reactive Agility measurement tool in net game group sports. In terms of the research method, the researchers used a mixed-method approach, combining qualitative and quantitative methods. The research subjects consisted of seven academic and professional experts in the net game group sports. While the data collection technique used is the Delphi technique, related data were collected using a four-scale rating, whereby scale 1 indicated “not suitable”, scale 2 “indicated less suitable”; scales 3 and 4 “indicated “suitable”, and “highly suitable” respectively. For this validation, the data analysis was conducted using Aiken's formula. Which all aspects have high content validation because the V value is higher than Aiken's standard value (0.76). The respective values ​​for each aspect include; conceptual definition V = 0.952, measuring tool construction V = 0.952, sensors show a value of V = 0.905, test procedures V = 0.905, and scoring V = 0.952.
