We studied the relationship between the stand-up test using standing steps of different heights and isokinetic muscle strength of knee extension. In the stand-up test, whether or not a subject could stand-up on both legs or one leg from steps of different heights was assessed. As a result, the peak torque/body weight ratio was significantly greater in subjects who could stand on one leg than those who could not (p<0.05). In the subjects who could stand on one leg, the angle of peak torque (p<0.01) and total work (p<0.05) were significantly greater when using a step of lower height. It was revealed that while quantitative muscle strength (peak torque/body weight ratio) could be roughly evaluated by determining whether the subject could stand on one leg, the height of the step used in the stand-up test did not contribute to detailed evaluation of knee extensor muscle strength. However, using a step of lower height, it was found that the knee extensor muscle could function from the large flexion of the knee joint, thus making it possible to evaluate the qualitative muscle strength (angle of peak torque).
