The type and quality of feedback provided during instruction influences motor skill learning. Little is known of the effects of feedback on discrete dynamic movements that are integral to strength-training programs. The effects of three types of feedback on a weight-lifting skill were evaluated. Participants’ performance was predicted to benefit more from a combination of visual and verbal feedback cues than from visual feedback alone or verbal feedback alone. A mixed-model experimental design was employed to compare the effects of the three feedback conditions over 6 training sessions. Analyses of movement form indicated that with training participants in both the video+cues group and the verbal-only group improved while individuals in the video-only group did not. These results have implications for instructors seeking efficient methods of improving athletic performance.
