[Physiologic energy requirements of miners working in deep coal mines]

A time course study of energy balance was conducted in miners working in deep coal mines under a strict control of their nutrition using the method of estimating the energy value of food received and body mass. It has been established that mean daily energy requirement of a "standard" miner (body mass--70 kg, age--25-35 years) comprises 16529.7 kJ (3950.7 kcal) under conditions of fulfillment of the standard output, 6-hour working day, 2 days off.
