초록

The purpose was to compare heart rates and blood lactate concentrations determined by blood samples from two parts (finger tip and forearm vein) during swimming in three different water temperatures(22℃, 27℃, 32℃). 10 healthy males performed swimming exercises for 30 min in each water temperature at 50m min-1. Fingertip and venous blood lactate concentrations were determined by blood sampling before, post exercise and 30-min after post. We compared lactate by time, sampling sites and water temperatures. The results showed as the temperature was higher, the heart rate of post exercise showed the tendency to increase(p<.05). There was notable difference between blood lactate concentration of each temperature and sampling site(p<.05). There was significant correlation between fingertip and HR in 22℃ and between vein and HR in 27℃ and 32℃. These findings indicated that in lower water temperature blood lactate concentration from fingertip might be higher than real value because of the change of blood flow as the function of thermo-regulation.
