title: Relative Isoinertial Performance Expressions for the lsostation B-200.
abstract: Low back internal loads are dependent, in part, upon the weight of the body segments and the lengths of their moment arms. Musculoskeletal performance appears to be influenced by anthropometric characteristics. The purpose of this investigation was to compare dynamic isoinertial performance values to selected individual and permutated anthropometric characteristics. Torque production was assessed during repetitive movements in the axis of trunk flexion/extension in 7 sedentary healthy females. Body fat, stature, and other anthropometric characteristics were measured to predict segmental weights and heights and to express relative performance scores. Pearson correlations ranged from 0.67 to 0.93 between peak torque production and peak torque expressed by both the weight and length of the spine motion segment. These findings appear to be significant because they enable a precise comparison of performance. J Orthop Sports Phys Ther 1990;12(2):60-65.
