Estimation of the wrist path radius in hammer throwing using a wrist-mounted inertial measurement unit: Validation against optical motion capture — Dataset

Data correspond to five throws performed by one experienced male hammer thrower. The dataset includes: (1) IMU data from two Movella DOT sensors (left wrist and right foot) sampled at 120 Hz (Euler angles, tri-axial accelerometer, gyroscope, and magnetometer); (2) VICON motion capture data at 120 Hz with 15 body markers and model outputs (joint angles, angular velocities, marker 3D coordinates); and (3) MATLAB .mat files containing the computed wrist path radii using four VICON-based methods (geometric, kinematic, Lee, and centroid-based) and the IMU-based radius estimate.

Event timing data for turn segmentation are also included.
