Abstract
The aim of this study was to determine the degree (percentage) of upper body morphological asymmetry amongst elite international male javelin throwers, as it could possibly negatively affect the health of athletes and hinder optimal sporting performances. Nineteen javelin throwers with an average age of 26.4 ±4.4 years, were measured on both the dominant and non-dominant sides of the upper body. Twelve anthropometrical variables (three skinfolds, five girths, three segment lengths and one breadth) were measured according to the methods described by Norton et al. (1996). The percentage of morphological asymmetry was determined by making use of Wolanski's Relative Indices of Asymmetry (RIA) as used by Copley (1980). The dominant and non-dominant side measurements were compared by means of dependant t-tests. Statistically significant differences between the dominant and nondominant sides were found for the relaxed arm (p South African Journal for Research in Sport, Physical Education and Recreation Vol. 27(2) 2005: 47-55
