As a result of global warming, including the heat island phenomenon, kendo practice by students and pupils during summer vacation is under threat. Based upon one climate index (Wet-Bulb Globe Temperature), it is recommended that kendo practitioners take rest breaks and drink plenty of water in the heat to avoid hyperthermic disorders. Currently, however, practitioners have no convenient means of evaluating if their rest time and water intake is sufficient or not. In the hope of finding a way to use the heart rate as a vital sign representing the threat of hyperthermic disorders, the heart rates and rectal temperatures of college kendo club members were monitored during midsummer practices. Their heart rates at maximal oxygen uptake in an ambient temperature of 25°C were also determined for reference. In a case where the highest recorded rectal temperature exceeded 39°C, the abrupt rise in rectal temperature was recorded during a jigeiko practice session together with a gradual increase in the lower levels of rapidly fluctuating heart rates. Such a heart rate response is considered to be a physiological response to an elevation of the core body temperature. Therefore, we suggest that those who practice kendo in the heat should self-check themselves to determine their likelihood of falling victim to hyperthermic disorders by paying attention to their heart rates during brief breaks between physical action during practice. In addition, as the measurements we took indicated that the highest rectal temperature was attained at the end of a contiguous practice sessions, one could probably check retroactively for the threat of hyperthermic disorders by taking an axillary temperature using an ordinary clinical thermometer.
