Effects of thermal, personal and behavioural factors on the physiological strain, thermal comfort and productivity of Australian shearers in hot weather

Article Abstract:

Forty-three men were studied throughout 54 man-days of shearing sheep and pressing wool bales to gauge the effects of separate and combined factors that are commonly expected to influence strain and productivity in a hot workplace. These experiments were carried out by keeping certain conditions constant. Subjects were men of 18-59 years, fat-free mass of 44-77 kg, and body fat content of 11-26 percent, who had drunk an estimated 0-207 g alcohol the previous evening. Results of the experiments are discussed.

Upper-arm elevation during office work

Article Abstract:

Work tasks should be designed to provide variations in arm and shoulder movements to decrease the likelihood of neck-and-shoulder injuries that are caused by repetitive movements. Analysis on the frequency of muscoskeletal stress during extensive work reorganizations indicated that changes in office work-tasks did not improve arm postures or reduce shoulder stress. The subjects exhibited arm elevations below the 30 degree limit and 73% complained of shoulder stress after their tasks were reorganized.

Selected physiological and psychobiological responses to physical activity in different configurations of firefighting gear

Article Abstract:

Analysis of specific psychobiological and physiological responses to various types of protective firefighting costumes reveals that for an absolute workload the NFPA 1500 standard gear causes more stress on the body compared to hip boot or station blues configurations. Further research needs and implications are discussed.
