The purposes of this study were to examine the sex differences in structure of experiential knowledge regarding movement of sprint running, to estimate degree of subjective importance of the knowledge, and to clarify the relationshiip between both. Thirteen hundred and six college athletes participated in this study. The first questionnaire was designed to determine the key items fo investigate the structure of experiential knowledge regarding movement of sprint running and 224 items were chosen. The degree of importance of each item was assessed on 7-point rating scale. MDSCAL and COSCAL were applied to a dissimularity matrix in terms of each part of the body (i.e., head, arms, torso and legs), the extracted dimensions were rotated orthogonally based upon Normal Varimax criterion.Additionally, SMACOF, KARASCAL, IMDSCAL and ICOSCAL were applied to the data in terms of each part of the body so as to examine suitability of Weighted Euclidean Distance Model(WEM) and Simple Euclidean distance Model for each group (SEM) as representing the sex difference of structure. Furthermore, Schonemann's general Procrustes rotation was applied to ensure an appropriate comparison. similarity of the dimensions of male and female were evaluated by coeffidient of congruence. Nextly, the degree of importance of each item was estimated and sex differences were evaluated. Lastly, the relationship between the dgree of subjective importance and the dimension was evaludted with multiple regression analysis. Analysis of data indicated that three-dimensional spaced for head and torso, and four for arms and legs were good enough to explain the structure of experiential knowledge in each group. Thus the number of attributes systematizing knowledge are equal in both groups.Obvious differences were recognized in goodness of fit between SEM and WEM, so that sex differences in structure were assumed to be qualitative. It could be infered that the degree of importance of each item estimated in this study reflects specific knowledge regarding movement of sprint running because of high similarity between the results and general opinion of specialists in this field. High multiple correlations were obtained with regression analysis in all parts of the body, so that the degree of subjective importance was assumed to be determined with linear function of the dimensions obtained in this study.
