This dataset contains processed skeletal keypoint 2D coordinates and joint angles (hip and knee) extracted using the MediaPipe framework. It includes data from three types of squat postures: standard squats, shallow squats, and good morning squats, performed by 22 subjects. The dataset is specifically designed for validating lightweight squat posture detection and biomechanical analysis algorithms. To protect subject privacy and comply with ethical restrictions, raw video recordings are excluded from this repository.
