Compute for the recommended length of rest break. Trst = Where: Trst = rest time, min Twrk = working time, min Twrk (ERwrk-ER) ER ERrst ERwrk = energy expenditure rate associated with physical activity, kcal/min Problem: ER = Time-weighted average energy expenditure rate, kcal/min ERrst = metabolic rate of worker while resting, kcal/min A male worker performs physical labor that has an energy expenditure rate of 8.2 kcal/min for 20 min. During the res breaks, his energy expenditure rate is estimated to be 1.5 kcal/min. The energy expenditure rate of the physical activity at the maximum time-weighted average during shift for male worker is 5 kcal per min. Determine an appropriate length o a rest break.
