dc.description.abstractThis study aimed to develop a sit-up test instrument using a Kinect camera to accurately measure performance and evaluate the quality of sit-up movements. It used a Research and Development (R&D) design. The subjects consisted of 55 male athletes aged 15-22 years, representing several sports, namely rowing, diving, volleyball, football, table tennis and Sepak Takraw, with an average height of ± 177.8 cm, average body weight ± 67.9 kg. Product testing was first conducted on a small group of 15 participants, followed by a re-test on a larger group of 40 participants. This process aimed to evaluate the consistency and readiness of the developed product. The study involved three experts in sports testing, biomechanics, and software to assess the validity, practicality, and effectiveness of the designed product. From the results of the assessment, the sports test and measurement expert received a score of 81, the sports biomechanics expert is 87 and the software expert is 86. The Cronbach's alpha (α) values are 0.82 and 0.78, required for reliability. The Kinect camera-based sit-up test instrument was found to be effective and efficient to use, with results that are valid and reliable in the very good category. However, a limitation of this tool is that it cannot be used outdoors, as the Kinect camera is not optimal for capturing movements under sunlight.
