This study demonstrated the effects of physical activity
in a hot environment on physiological parameters, as shown
by an increase in Tty and HR. This physiological heat stress
cause mild changes in serum parameters of blood clotting
such as prothrombin time, while antrithrombin values were
not affected by the stress. Contrary to the expected, platelet
count increased during exertional heat stress.
A 10-day acclimatization, either passive or active,
showed no effect on parameters investigated, possibly due to
a preexisting high level of aerobic capacity and tolerance to
heat, which could not be additionally improved.
