Título A comparison of physiological strain of carriers in underground manual coal mines in India
Información bibliográfica 3rd quarter 2008, Vol.14, No.3, p.210-217. Illus. 37 ref.
Resumen Thirty-nine healthy carriers (23-57 years of age) were investigated in underground manual coal mines in West Bengal, India during two different work spells of a single work shift. The physiological strain of workers <40 and > or =40 years of age were compared. For both groups, mean heart rate was 124-133 beats/min, with a mean corresponding relative cardiac cost of 50-66%. Maximum aerobic capacities were estimated indirectly, following a standard step test protocol. Average oxygen consumption was 1.07-1.1 L/min, with an energy expenditure of 5.35-5.5 kcal/min among both age groups. Acceptable levels of physiological strain were well encroached, and older workers faced the maximum burden. The tasks studied were heavy to very heavy in nature. There is extreme need of ergonomic interventions in reducing the postural load and musculoskeletal discomforts in this population.
