It is not uncommon to see men and women routinely carry head-supported loads like Sherpa mode where a load slung on the back and supported by a strap around the forehead. This type of load carriage has been shown to cause significant postural discomforts, mainly on head, neck and shoulders. Therefore, this experiment was conducted to examine effects of hip belt and shoulder straps on Sherpa mode of load carriage for assessment of physiological and perceptual responses. It was hypothesized that the support on hip belt and shoulder straps supported in Sherpa mode would elicit lower physiological and perceptual responses... |
