ranged between 178-333 W (females) and 212-542 W (males), with the corresponding
external work rate ranges being 36-67 W (females) and 42-108 W (males). On average, these
data represented only 25-40% (females) and 30-45% (males) of the maximal capacity for
healthy adults of average physical fitness. Such work rates are quite sustainable for 5-8 hours
in healthy adults.
Approximately 66% of all core temperatures were within the range 37.3-37.7 o C, and 66% of
the peak temperatures ranged between 37.6-38.8 o C. Only one stockman exceeded a core
temperature of 39 o C, while four others had peaks >38.5 o C, but 0.05). That is, both the shirt and helmet behaved
similarly with respect to heat transfer, such that the helmet did not appear to disadvantage
stockmen more than would any other garment worn on the head.
On average, stockmen reported significantly greater psychophysical strain following
mustering (P
