The purposes of this study were to clarify features of sprinting forms of ball game players, and to examine rational sprinting forms for ball game players. Subjects were 33 male ball game players such as soccer and rugby (defined as B group), 19 male sprinters (included long jumpers, S group) and 9 untrained males (U group). Sprinting forms of subjects were recorded by high speed video-camera from right side. Dynamic variables which were obtained from video analysis were compared among three groups, and in each group, the coeffients of correlation were calculated among variables.Results were as follows:1) Running velocity and stride ratio (stride/body height) were excellent S, B, U group in that order. B group showed smaller ratio of contact time to air time than S group.2) In B group, there was significant correlation between the ratio of contact time to air time and the leg angle at the moment of take-off.3) High step frequency was one of the features of ball game players sprinting.4) B group showed remarkable flexion of knee in contact phase in comparison with S group.
