Although much informations were presented for the estimation of VO_2/energy expenditure from running velocity on snowless surface, few information are reported regarding to the relationships during snowfall season. Exercise intensities and the gait characteristics of walking and running were determined during non-snowfall season and snowfall season for the purpose to elucidate the characteristics of walking/running during snowfall season. The results were summalized as follows :(1) VO_2 in ten healthy elderly male subjects during walking on packed snow were 3 to 4 ml/kg/min (1 Met) higher than these during walking at the same velocity on non-snowfall season.(2) Mean values in the heart rate during running on packed snow at the same velocity were 6 to 8 beats/min higher, and VO_2 were 2 to 3 ml/kg/min higher than these during running on snowless surface. Blood lactate concentration in each subject during running on packed snow increased at lower velocity than these on snowless surface.(3) There were tendencies of increasing exercise intensities and decreasing stride length during running on slushy snow comparing with snowless surface or packed snow. These difference were enlarged as the velocity increase.It was concluded that exercise intensities and gait characteristics were largely influenced by nature of snow on surface.

虽然在无雪路面上由行驶速度估算VO_2/能量消耗的资料很多，但在降雪季节，关于两者关系的报道很少。通过测定非降雪季节和降雪季节的运动强度和步行、跑步的步态特征，探讨降雪季节步行/跑步的特征。结果表明：（1）10名健康老年男性在积雪上行走时的VO_2比非降雪季节同速度行走时的VO_2高3 ~ 4 ml/kg/min（1 Met）。(2)在积雪上以相同速度跑时，心率平均比无雪时高6 ~ 8次/min，VO_2平均比无雪时高2 ~ 3 ml/kg/min。在积雪上跑步时，受试者的血乳酸浓度在较低的速度下比在无雪路面上增加。(3)与无雪路面和积雪相比，在半滑雪路面上跑步时，运动强度有增加的趋势，步幅有减小的趋势。结果表明，雪面性质对运动强度和步态特征有很大影响。
