Method and performance: two elements of work technique

Article Abstract:

A study was conducted to examine how selected kinetic, kinematic, electromyographic and psychophysical variables can characterize the method and performance of work technique when applied to lifting tasks. Likewise, a measurement of ground reaction forces, motions, muscle activity in the lower back and perceived exertion was conducted. Results implied that separate variables should be used for descriptions of work methods and task performances. Moreover, individual differences indicated that work technique should be assessed on an individual level.

Foot positioning instruction, initial vertical load position and lifting technique: Effects on low back loading

Article Abstract:

Four lifting techniques in 10 subjects performing 19 different lifting movements were observed to study the effects of initial load height and foot placement instruction and measure kinematics and low back loading. Results showed that the task context determines the effects of lifting techniques on low back loading.

Gender differences in lifting technique

Article Abstract:

This article discusses the results of a study that evaluated gender differences in motion patterns and lifting technique. Utilizing an opto-electronic measurement system to measure movements the authors maintain that the women tested were more synchronized than the men regarding hip-knee interjoint coordination.
