The purpose of this study was to determine the relationship between five common methods of measuring isometric trunk strength and endurance: Isometric flexion and extension tests, an upright lifting task, and timed isometric flexion and extension endurance tests. Fifty-six healthy individuals (aged 18--65 years) with no history of back problems or disease volunteered for this study. Data were analyzed using a Pearson Product Moment Correlation Coefficient and Student's T-test. Significant relationships (p<0.0001) were found between the B-200 isometric extension and upright pull (r=0.75); B-200 isometric flexion and upright pull (r=0.78); and B-200 isometric flexion and B-200 isometric extension (r=0.80). Men demonstrated greater strength than women in B-200 isometric flexion and extension, as well as in the upright pull measures (p <0.05). A variety of measures are frequently used to evaluate trunk ``strength'' in force production and endurance. Although strong correlation was observed among measures of force, no significant relationships were demonstrated between endurance and force measures. This suggests that a subject who demonstrates a strong performance on strength test of force may not necessarily display an equally strong performance on a strength test of endurance. Hence, to obtain a full picture of a person's performance capabilities, measures of both force and endurance should be incorporated into evaluation protocols. |
