The authors examined the physiological changes of men riding motorcycles carrying different loads. Nine healthy professional riders were the subjects. They used professional Honda MD 90B-90CC motorcycles. Each subject made test rides with the loads of 0, 10, 15, and 20 kg, taken at random, on a concrete road for 20 min at a speed of 30 km/h. The environmental temperature at the time of the test, skin temperature, vibration sense threshold at a vibration level of 125 Hz, critical flicker fusion frequency, pinching power, grasping power, pulse rates, and blood pressure were measured. The pulse rates were significantly different for the rides with the four different loads, and the changes in pulse rate after the ride with the loads of 10 and 20 kg were comparatively higher than those before the ride. The changes of systolic blood pressure after the rides with the loads of 15 and 20 kg were significantly higher than those before the rides. The other changes observed were not significantly different.
作者研究了骑乘搭载不同负载的摩托车时男性的生理变化。九名健康的职业骑手作为研究对象。他们使用专业的本田MD 90B - 90CC摩托车。每位受试者在混凝土道路上以30公里/小时的速度随机搭载0、10、15和20公斤的负载进行20分钟的测试骑行。测量了测试时的环境温度、皮肤温度、125赫兹振动水平下的振动感觉阈值、临界闪烁融合频率、捏力、握力、脉搏率和血压。搭载四种不同负载骑行时的脉搏率有显著差异，搭载10公斤和20公斤负载骑行后的脉搏率变化相对高于骑行前。搭载15公斤和20公斤负载骑行后的收缩压变化显著高于骑行前。观察到的其他变化无显著差异。
