An assessment of energy expenditure has been made in 50 male textile workers and 30 male office cleaners. There was a statistically significant difference (P less than 0.001) in energy expenditure between textile workers and office cleaners amounting to 12 to 16%. While 33.3% of the textile group complained of chest disorders, none of the cleaners had such(More)
