Measurement of Hemodynamics During Mountaineering by Multi-Sensor Ambulatory Blood Pressure Monitoring Device
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.40 Vol.40】
ABSTRACT
The purpose of this study was to clarify the blood pressure （BP） and physiologicalresponse during mountain climbing and stay in high altitude. Six healthy adults climbedMt. Fuji with measuring blood pressure by multi-sensor ambulatory blood pressuremonitoring device. Pulse oximetry was performed during sleep in the research stationat the summit of Mt. Fuji. BP during mountain climbing was higher than BP in dailylife （24-hour systolic BP: 117.8±5.4 mmHg vs 111.4±5.8 mmHg, p=0.04. awakesystolic BP: 123.4±6.9 mmHg vs 115.2±7.2 mmHg, p=0.03）．Awake systolic BPduring mountain climbing was correlated with physical activity （R=0.87, p<0.05）．In addition, one subject with acute mountain sickness （AMS） showed abnormal circadian BP rhythm. The present study showed that BP during mountain climbingwas associated with physical activity, and abnormal circadian BP rhythm may occur inAMS. We should pay attention with BP elevation and abnormal circadian BP rhythmduring mountain climbing in high altitude.
