Assessment of the physiological response due to high-speed motorcycle driving using frequency component time-series of heart rate variability

摘要

Physiological responses during high-speed motorcycle (MC) driving were examined. Electrocardiogram R-R intervals (RRI) of 18 professional riders driving MC at the speed of 50, 200, and 220km/h were measured on a specific oval course. Using digital filters, four bands of RRI variability components, which related to stationary component (0.06-0.5Hz), parasympathetic nervous systems(0.15-0.5Hz), difficulty in driving(0.012-0.025Hz) and trend (0-0.012Hz) were extracted. Changes in the magnitude of these components with driving speed were discussed.
