Recently Mc Gill postulated a new method to evaluate trunk muscle performance in 4 tested postures: isometric endurance test of back flexion 60° and extension and both side bridge exercise, good reliability was addressed. However, there is large variation in his data of endurance time at back flexion 60°. Thus two kinds of abdominal flexion postures (back flexion 45° and curl up) were added for comparison. Besides the study about influence of anthropometrical factors on trunk muscle endurance is not satisfactory, so body fat percentage and body mass index (BMI) data were recorded and analyzed. Material and method: (1) 30 healthy young nurses participated this study and finally 28 nurses were included.(2) 6 posture were tested (back flex 60°, back flexion 45°, curl up, back extension, left and right side bridge exercise).(3) body fat percentage and BMI were recorded. Results: (1) the endurance time at back flexion 60° is 375.4±252.5 seconds which is longer than Mc Gill''s data.(2) no significant difference between back flexion 45° and curl up posture.(3) body fat percentage is 25.09±5.11 (3) the BMI is 20.03±1.97(4) there is no correlation between endurance time and body fat percentage and BMI. Conclusion: the curl up posture is most preferred among 3 abdominal flexion postures for its good reliability and convenience, the back flexion 60° test posture should be used cautiously; and if test of oblique abdominal muscle must be emphasized, the back flexion 45° posture may be chose.下背穩定運動耐受時間測試Low Back Stabilization ExerciseEndurance Time Testthesis
