CoreExercise5K: A Machine Learning Dataset for Core Exercise Assessment

CoreExercise5K is a tabular dataset composed of 3D skeletal landmark coordinates and joint angles extracted using MediaPipe Pose. It was curated for machine-learning-based physical therapy and real-time core exercise posture auditing.

📌 Dataset Overview

• Total Samples: 5,016 rows
• Number of Features: 108 columns (33 MediaPipe pose landmarks $\times$ $x, y, z$ coordinates + derived joint angle attributes)
• Target Variable (label): 9 classes (8 core exercise movements + neutral/none)
• Modality: Tabular / Skeletal Landmarks (Normalized 3D coordinates)

🔬 Data Collection & Preprocessing

1. Raw Frame Acquisition: 920 high-quality frames across diverse subjects performing physiotherapy core exercises were curated.
2. Data Augmentation: An augmentation pipeline applied 6 transformations to each frame:
   • Original frame
   • $+15^\circ$ rotation
   • $-15^\circ$ rotation
   • Horizontal flip
   • Flipped with $+15^\circ$ rotation
   • Flipped with $-15^\circ$ rotation
     (Yielding a theoretical maximum of $920 \times 6 = 5,520$ frames)
3. Landmark Detection & Quality Filtering: Each augmented frame was passed through the MediaPipe Pose model. Frames with occlusions or missing keypoints where MediaPipe failed detection were filtered out, resulting in 5,016 clean, fully labeled keypoint vectors.
