Differential Learning Enhances Motor Performance and Retention in Sport Science Students

This randomized controlled trial compared differential learning (DL) versus blocked practice (BP) on motor performance and retention in 100 sport science students. Participants performed a table tennis topspin serve. DL involved continuous movement variations without corrective feedback; BP involved repetition with corrective feedback. Outcomes included accuracy (Euclidean distance) and movement variability (ApEn). Assessments at baseline, post-intervention (after 6 sessions over 3 weeks), and 7-day retention.
