This study examines the effects of ground surface, load, one- and two-wheeled wheelbarrow on muscular activities, hand force, and subject-perceived exertions while pushing a wheelbarrow in a straight line on a horizontal surface. The experimental results show that wheelbarrow load significantly affected muscular activities, hand force, and subject-perceived exertion. Additionally, different ground surfaces and wheelbarrow types also affected the muscular activities of the dominant hand; grass generated the highest muscle load and asphalt pavement generated the smallest muscle load. The user has to apply 57% and 23% more force in the vertical and horizontal direction while pushing one-vs. two-wheeled wheelbarrow. Muscular activity increased significantly in the dominant hand with the one-wheeled wheelbarrow compared with the two-wheeled wheelbarrow, suggesting that, in terms of muscle loads, the two-wheeled wheelbarrow is better than the one-wheeled wheelbarrow.

这项研究研究了在水平方向上沿直线方向推独轮车时，地面，负载，单轮和两轮独轮车对肌肉活动，手力和受试者感知的运动的影响。实验结果表明，独轮车负荷会显着影响肌肉活动，手部力量和受试者感知的劳累力。此外，不同的地面和独轮车类型也影响了优势手的肌肉活动。草产生最大的肌肉负荷，而沥青路面产生最小的肌肉负荷。使用者在按一对一的同时要在垂直和水平方向上分别施加57％和23％的力。两轮独轮车。与两轮独轮车相比，单轮独轮车的显性手的肌肉活动显着增加，
