Supplementary data and analysis code for: Velocity-regulated jump-squat training in youth swimmers

This dataset contains de-identified individual-level outcomes, trial-level swimming-start data, and analysis code associated with an uncontrolled pre-post feasibility study of velocity-regulated jump-squat training in youth swimmers. Raw video files are not shared because participants were minors and the recordings contain identifiable images. Session-fidelity and swimming-load records can be made available to editors or reviewers on reasonable request, subject to de-identification and institutional ethics restrictions.
