Foot placement strategy in pushing and pulling
1Department of Industrial Management and Information, Southern Taiwan University of Science and Technology, Tainan, Taiwan.
Background:
Pushing and pulling tasks are very common in daily and industrial workplaces. They are one major source of musculoskeletal complaints.
Objective:
This study aimed to examine the foot placement strategy while pushing and pulling.
Participants:
Thirteen young males and ten young females were recruited as participants.
Methods:
A two (pushing and pulling) by four (48 cm, 84 cm, 120 cm, and 156 cm) factorial design was used.
Results:
Exertion direction and exertion height significantly affected foot placement strategy. Pushing task needed more anteroposterior space than pulling task. The percentages of female/male for trailing foot position ranged from 77% to 90% (pushing) and from 80% to 93% (pulling) across the exertion heights.
Conclusion:
Practitioners should provide an anteroposterior space approximately to 70% body stature for workers to exert their maximum pulling and pushing strengths.
