Psychophysically determined infrequent lifting capacity of Chinese participants

Article Abstract:

Back injury is a global phenomenon, and manual materials handling (MMH) has been identified as one of the major causes. A psychophysical lifting capacity for Chinese male and female participants for infrequent lifting activities was developed, and differences between Chinese and Occidental populations were compared. The results show that the maximum acceptable weight of lift (MAWL) was significantly affected by lifting frequency and height. Chinese participants had smaller capacities than Occidental participants.

Physiological and perceptual responses to load-carrying in female subjects using internal and external frame backpacks

Article Abstract:

Ergonomic research on women showsthat there is little load-carrying efficiency difference between internal and external backpack frame designs. The test subjects were made to carry packs loaded with 33% of their body weight over different terrain conditions. The physical aspects of load carrying are shown to be unaffected by the considered factors during laboratory studies. The perceived load-carrying advantages of internal backpacks are therefore considered to be physiological in nature.

Psychophysical determination of load carrying capacity for 1-h work period by Chinese males

Article Abstract:

A study of 12 Chinese men measured the amount of weight they could carry over a 1 hour period and how the weigh and the type of container affected them physically and psychologically. Containers with handles allowed the men to carry 21% more weight and with less physiological stress.
