摘要: OCCUPATIONAL APPLICATIONS We found markedly different muscular exposures and external hand force-generating muscle efficiencies when individuals produce maximal pushing pulling forces in several experimental conditions (e.g., 100 cm versus 150 cm handle height, horizontal verss vertical grip orientation). For the same task characteristics, females produced higher levels of activation ratios normalized activity to force, which were likely result differing anthropometry between sexes. Females thus appear be at risk for overload during push/pull tasks. Pulling waist height shoulder are recommended possible, similar those studied. The high prevalence tasks occupational settings enables use these findings, concert with traditional strength-based ergonomics assessments, help protect both males from potential musculoskeletal overload.TECHNICAL ABSTRACT Rati...
