Details

The dataset contains example physiological, environmental and clothing data required for the heatex function.

There are 21 variables required for the heatex function as follows: 1. time = Total time for physical activity in minutes. 2. workrate = The work rate (power output) of the activity in watts. 3. ht = Subject height in centimetres. 4. wt = Subject body mass in kilograms (to calculate the body surface area, usual body mass). 5. bmi = Subject body mass before commencing physical activity in kilograms. 6. bmf = Subject body mass after physical activity in kilograms. 7. fluidfood = Fluid and food consumption during the physical activity. 8. urinefaeces = Urine and faeces loss during the physical activity. 9. sweat = Dripped sweat in grams. 10.tci = Initial body core temperature in degrees celsius. 11.tcf = Final body core temperature in degrees celsius. 12.tski = Initial skin temperature in degrees celsius. 13.tskf = Final skin temperature in degrees celsius. 14.vo2 = Oxygen consumption in litres per minute. 15.rer = Respiratory exchange ratio. 16.tdb = Dry bulb temperature of the environment in degrees celsius. 17.tg = Black globe temperature in degrees celsius. 18.va = Air velocity in metres per second. 19.pa = Ambient water vapour pressure in mmHg. 20.icl = Intrinsic clothing insulation in m2.oC.W-1. 21.tcl = Temperature of the outer body surface, including clothing temperature if relevant, in degrees celsius.
