This study supports the development of a one-arm push-up test for para-athletes with unilateral transradial deficiency/amputation by assessing its characteristics, reliability, and validity with a sample of 16 healthy young men. The participants were monitored for the level of physical discomfort during and after the test, and their safety was assured. We found that the number of push-ups achieved was significantly higher than that obtained on the normal push-up test (t = -2.40, p ＜0.05). The load on each muscle involved during the movement may differ between the one-arm push-up and the normal push-up test. The intraclass correlation coefficient for the one-arm push-up test was 0.82. The participants took the test twice. There was no significant difference between attempts, indicating that the one-arm push-up test might have high reliability. The normal push-up and the YMCA bench press tests, which measure the muscular endurance of the upper limbs, were adopted as standard validity assessments for the one-arm push-up test. The correlation coefficient between the one-arm push-up and normal push-up test was r=0.52, p＜0.05. Additionally, the one-arm push-up test correlated significantly with the YMCA bench press test (r=0.54, p＜0.05). These results suggest that the one-arm push-up test can evaluate muscular endurance of the upper limbs as accurately as the standard tests. Therefore, the one-arm push-up test could be a valid and reliable method to measure the muscular endurance of the upper limbs of healthy young men. Future studies should examine the reliability and validity of the one-arm push-up test for para-athletes.
