[Effect of elevated external temperature on diurnal fluctuations of pulse and blood levels of glucose and lactic acid].
Studies were performed in two 24 hrs' series. In series I, subjects (6 students of Physical Education Academy, aged 21-22) stayed at 18 degrees C and 36% humidity, whereas in series II every 2 hrs at 18 degrees C and 50 degrees C from 6.00 to 6.00 next day. Identical diet was applied for both series. Levels of glucose and LA in blood were determined by modern enzymatic microtechniques, using the Boehringer Firm tests. 24 hrs fluctuations in the pulse, levels of glucose and lactic acid (lesser at night), accompanied by a significant impact of increased external temperature upon the mentioned indices were found. Apart from statistically significant fluctuations at different times of the day and night, also statistically significant differences in 24 hrs' mean values of the parameters between both series were found.
