The purpose of the study was to examine the influence of critical cues and task constraints on body-component levels and maximum ball velocity. 81 children (M age = 97.8 me.) were systematically assigned to one of four strategies. Participants completed 15 throws during each of 4 practice sessions. Differences between groups were found for body-component developmental levels and ball velocity. The differences indicate prompts to throw the ball hard and fast impact ball velocity and body-components by developmental levels. Critical cues also appear to be a useful tool to improve the step component. Results suggest the use of forceful throwing tasks, cues, and velocity feedback can be useful tools to influence throwing performance.
