The aim of this study was to evaluate test-retest reliability of a dynamometer in measuring lifting strength or force parameters under several combinations of ergonomic factors. Thirteen healthy participants were tested on peak force (PF), related variables and isometric strength (IS) twice, at intervals of 3 months. Correlation coefficients for all parameters in the sagittal plane were 0.60 - 0.85. Coefficients of variations (CVs) of methodology error for PF in the sagittal plane were 6.2- 6.9% . Correlation coefficients and CVs for IS at 90 to the lateral plane were 0.51 - 0.54 and 16.6- 17.9% , respectively. In paired t -tests of the parameters under all conditions, there was no significant difference between test and retest. In the test and retest, ratings of perceived exertions for the low back and the right arm in isometric lifting were significantly higher than those in dynamic lifting. It was concluded that the test-retest reliability of dynamic forces in the dynamometer was high. The peak force in the sagittal plane was considered reliable. In isometric lifting, isometric strength in the sagittal plane seemed reliable, while that at right angles to the lateral plane was considered to be less reliable.
