Humans - Required Rest Time

Relaxation rest time vs. working time and activity.

Sponsored Links

Required rest or relaxation time related to working time and power expenditure can be estimated as:

tr = tt (qt - qm) / (qt - qr)                                    (1)

where

tr = required relaxation or rest time (minutes)

tt = task or work time (minutes)

qt = task or work power consumption (W, watts)

qm = maximum power consumption level in a day with no recovery requirement (W, watts) (approximately 350 Watts for most male workers, approximately 300 W for most female workers)

qr = resting power consumption (W, watts) (commonly between 70 - 100 W)

Example - Required Relaxation Time

Required rest time for a male worker in very heavy work with task power consumption 600 W, resting powewr 100 W and task time 60 min, can be calculated as

tr = (60 min) ((600 W) - (350 W)) / ((600 W) - (100 W))

    = 30 min
