No sweat -- workout women do 'glow'
Women really do glow rather than sweat, research has shown.
Researchers studied volunteers of both sexes on exercise bikes and found that women took longer to get sweaty.
Participants were split into "trained" and "untrained" groups and asked to pedal non-stop for an hour.
At intervals they had to heighten the pace in spurts of increasing intensity.
Untrained females took longest to work up a sweat, needing a higher body temperature before they started to perspire. Sweating helps athletes by keeping their bodies cool and increasing stamina.
Study leader Dr Yoshimitsu Inoue said: "It appears that women are at a disadvantage when they need to sweat a lot during exercise, especially in hot conditions."
Previous research has shown that men produce larger volumes of sweat than women, partly because of the male hormone testosterone.
