Content Validity of Android-Based Sport Training Program Monitor For Tennis Players

Tracking an athlete’s training program is crucial for objectively monitoring training activities, physical development, skill acquisition, and program adjustments. This research aims to develop an Android-based application for monitoring sports training programs tailored for tennis players. The study employs both quantitative and qualitative research methods, analyzed using Aiken’s V formula. Participants included 5 licensed tennis trainers, 5 strength and conditioning experts, and 3 technology specialists. The results show V coefficient values ranging from 0.90 to 1.00, with a mean value of 0.97, indicating high validity according to tennis coaching experts. Evaluation of the physical condition of tennis players yielded V coefficient values between 0.90 and 1.00, with a mean of 0.96, reflecting high validity of all items. Furthermore, expert assessments in technology and informatics produced V coefficient values from 0.83 to 1.00, with a mean of 0.93, indicating high validity of all items. Therefore, this research confirms that all test items have a high level of content validity. With this high validity, the application can be effectively used by coaches to manage the training programs and daily activities of tennis players.
