The strengths of both push and pull using both hands at handle heights of 75, 90, and 135 cm were measured for 11 female and 8 male participants. In addition, simulated push and pull tasks were performed on one of the three heights as in the strength measurements. In these tasks, the participants either pushed or pulled a swing suspended with one of the two loads (32.5 and 42.5 kg) until they could no longer do so. Then, the strength of push or pull was measured again. The participants also reported bodily discomfort on their body parts on a CR‐10 rating scale. It was found that hands and leading leg had the highest CR‐10 scores among the body parts and were the bottleneck body parts for the push and pull tasks, respectively. Models of maximum endurance time incorporating gender and handle height, in addition to force ratio, were developed. These models may be adopted in predicting the endurance time in job design concerning work/rest arrangement.

考虑性别和手柄高度的推拉任务的最大续航时间建模

测量了11位女性和8位男性参与者在75、90和135 cm手柄高度下用双手进行推拉的力量。另外，在强度测量中，在三个高度之一上执行了模拟的推拉任务。在这些任务中，参与者要么用两个负载（32.5和42.5公斤）之一悬挂的秋千推拉，要么再拉不动。然后，再次测量推拉强度。参与者还报告了其CR-10等级量表对身体部位的身体不适。结果发现，手和前腿在身体部位中的CR-10得分最高，分别是推和拉任务的瓶颈身体部位。除了力比，还开发了结合性别和手柄高度的最大耐力时间模型。
