Abstract

The purpose of this study was to collect normal flexion and extension trunk strength values for a population of individuals between the ages of 50 and 70 years of age. Twelve female and eight male volunteers in generally good health were tested in a seated position using a Biodex isokinetic dynamometer. Each performed five reciprocal maximal efforts of concentric flexion-extension cycles at the three isokinetic speeds of 60, 120 and 180{dollar}\sp\circ{dollar}/s. Raw and body weight adjusted data for peak torque and total work were analyzed. Results suggest strength decreases with age and that extension strength is greater than flexion strength. Due to the paucity of subjects in each of the four elderly age groups tested, no significant results were obtained.
