In order to obtain the physiological information during such outdoor exercises as cross-country running or skiing, mountain climbing or diving in the sea water etc, we developed a new device employing MEMORY IC. for monitoring and recording various biological information from the subjects during exercise with no restraint. The device is composed of detecting, data processing and recording units. The application of a semiconductor, CMOS MEMORY I.C. to the recording unit enabled us to construct the instrument, which is very compact (150g) and tolerant to the mechanical vibrations as well as the enviromental disturbances. The recorded data are read out by a microcomputor system. This device was applied to ten subjects during running, where the heart rate, respiration rate and body temperature were recorded. They covered a distance of 9 km within 60 minutes. The heart rate of five trained men was stabilized at nearly fixed level during running which was consistent results with those by the treadmill, but in the untrained men different results were shown from the trained. The heart rate of the untrained men showed that they encoutered the limits of the capacity on the way of running. These results showed wide applicability of this device for the physiological analysis of outdoor exercises.
