NCT07628465

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Motor Performance (Accuracy)

    Euclidean distance (in cm) between the ball's first landing point and the center of the target area during a table tennis topspin serve.

    Baseline, immediately post-intervention (after 3 weeks), and 7-day retention

Secondary Outcomes (1)

  • Movement Variability

    Baseline, immediately post-intervention (after 3 weeks), and 7-day retention

Study Arms (2)

Differential Learning Group

EXPERIMENTAL

Participants performed table tennis topspin serve with continuous variations across five movement dimensions (stance, backswing amplitude, execution speed, trunk rotation, wrist action) without corrective feedback.

Behavioral: Differential Learning

Blocked Practice Group

ACTIVE COMPARATOR

Participants repeated a standardized movement pattern with trial-by-trial corrective feedback focusing on consistency and accuracy.

Behavioral: Blocked Practice

Interventions

Participants performed table tennis topspin serve with continuous pseudo-random variations across five movement dimensions (stance, backswing amplitude, execution speed, trunk rotation, wrist action) without corrective feedback.

Differential Learning Group

Participants repeated a standardized movement pattern with trial-by-trial corrective feedback focusing on consistency and accuracy.

Blocked Practice Group
