Physiological and perceptual responses during Sherpa mode of load carriage: Role of hip and shoulder belt supports CIGR Journal
Patel, Thaneswer.
In the Northeastern hilly region of India, manual load carrying system is still widespread due to lack of transportation infrastructure. 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...

Ergonomic evaluation of battery operated knapsack sprayer CIGR Journal
Zilpilwar, Shubham; YADAV, RAJVIR; Sakariya, Ketan; Gahane, Manisha.
Spraying is one of the most important operations in crop production to protect the crops from attack of various pest and diseases. Ergonomic intervention in spraying operation can provide a reasonable basis for recommendation on operating methods and improvement in operation for more output and safety. The ergonomic evaluation of the commercially available sprayers such as battery operated, power operated and lever operated knapsack sprayer was carried out on the basis of heart rate, oxygen consumption rate, and energy expenditure rate. The rest pause, work load, musculoskeletal problems and overall discomfort rating in operators was determined. The average heart rate (HR), oxygen consumption rate (VO2) and energy expenditure rate (EER) of the subjects was...
