2007, Piran, Slovenia

Sweating
back/waist area and finally the lower-back sides. The lower back around the waist showed the
largest individual variation of all areas. Chest sweating was highest in the mid-front area,
followed in order by the top front and bottom front. The top of the shoulder was similar to the
average chest; the side slightly lower. The side of the arm had substantially lower sweat rates.
Male sweating increased during the run from 502 g.m -2 .h -1 after 30 min to 574 g.m -2 .h -1 after
45 minutes. Ten minutes after exercise stopped (time = 80 min), sweat rates had come down
substantially to 147 g.m -2 .h -1 .
The overall sweat rates in males (538 g.m -2 .h -1 ) during the run were higher than those in
females (481 g.m -2 .h -1 ), though this average difference was only around 10%. Females
sweated typically about 10% less in all areas, except the lower back sides, the arm, and the
upper chest (with breast included), which have roughly equal sweat rates in both genders. The
relatively higher sweat rates for the chest area (including the breasts) in the females may be
due to the higher clothing coverage of this area, a sports bra, which may have increased the
local heat load. The regional sweat rate data give a consistent picture, matching overall sweat
rates well. They are deemed a representative picture for this participant group in a 60-min
training run.
