title: Effects of different variations of mental and physical practice on sport skill learning in adolescents with mental retardation.
abstract: The purpose of this study was to investigate the effect of five variations of imagery and physical practice on learning of Basketball free throws in adolescents with mental retardation (AWMR). Forty AWMR were randomly assigned to five groups and performed a variation of practice: physical practice, mental practice, physical practice followed by mental practice, mental practice followed by physical practice, and no practice. The groups exercised the task for 24 sessions. Following training, posttest and retention test were taken. All variations of practice resulted in performance improvement, yet the mental practice followed by physical practice resulted in better improvement. The results suggest that mental practice associated with physical practice results in an outstanding performance improvement in AWMR.
