AbstractThe aim in this experiment was to determine whether demonstrations that focus on end-point related information, in this case, ball-trajectory information (BALL), are more effective in teaching motor skills than more traditional demonstrations which focus on movement technique (BODY). Nineteen participants with low-level soccer experience practised a left-footed, soccer-chip shot, which required them to land a ball on a target, while clearing a height barrier. Information concerning how to achieve the task goal was manipulated. Participants either received demonstrations of an expert performing the skill (i.e., BODY, n=10) or they received a demonstration of the expert's ball flight path (BALL, n=9). The participants were asked to match the criterion flight or form to achieve the task goal. Feedback concerning ball flight and movement form was controlled, although all participants received KR. Trials were videotaped for analyses and feedback and movement kinematics were collected using 3D cameras on a selection of trials. Both groups improved during acquisition although there was no significant difference between the groups in terms of outcome attainment (i.e., height success and radial error). In retention, the BALL group showed more accurate performance relative to the BODY group, when demonstrations and feedback were withheld (p<.05 only="" in="" acquisition="" were="" any="" differences="" between="" the="" two="" groups="" noted="" terms="" of="" movement="" kinematics.="" body="" group="" showed="" a="" closer="" approximation="" to="" model="" how="" various="" joint="" displacement="" angles="" obtained="" not="" actual="" comparison="" ball="" group.="" these="" results="" provide="" initial="" evidence="" support="" use="" end-point="" template="" matching="" strategies="" for="" teaching="" complex="" skills="" such="" as="" those="" common="" sports="" which="" require="" accurate="" some="" external="" object="" or="" disc="">
