Abstract: The purpose of this study was to determine the correlation of the selected anthropometric measurements with the trunk (extensors and flexors) muscle endurance for girls in government primary school children. One hundred fifty eight normal girls with age ranged from 7-12 years participated in this study. They were evaluated using selected anthropometric measurements [body weight (kg), body height (m) and body mass index (kg m¯2)] and trunk muscle endurance test. The results revealed that body weight and body mass index had negative correlation with trunk (extensors and flexors) muscle endurance (r = -0.16, -0.28, -0.3, -0.36, respectively). Regarding to body height; it had positive correlation with trunk extensors muscle endurance (r = +0.07) and negative correlation with trunk flexors muscle endurance (r = -0.08). It could be concluded that girls had weak relationship of body weight and body height with trunk (extensors and flexors) muscle endurance and moderate relationship of body mass index with trunk (extensors and flexors) muscle endurance. These results may be attributed to morphological variations and ages.
