Physique Characteristics of Ethnic Archers Based on R-cluster Matrix

Abstract

Object: the R cluster matrix analysis is used in this research which to explore the correlation of body shape, body composition, physical function and body function of male Xibo ethnic archers in China, and then discuss the differences of physical characteristics among Xibo ethnic archers and other athletes. Method: we used the R cluster matrix analysis and Hierarchical cluster diagram to build the model of physique index of male Xibo ethnic archers. Results:(1) The pyhsical characteristics of Xibo ethnic archers divided into three groups which are LBM/weight, weight and vital capacity, body fat ratio and VO2max;(2) According to T test, some indices such as body fat ratio are smiliar to the athletes of football and judo, but vital capacity and VO2max are lower than them. Conclusion: the body shape and pyhsical function of Xibo ethnic archers relate to obvious R cluster matrix, and the excellent physique characteristics need the advantage of strength endurance which no less than sports which need body contact, such as football, judo.
