This study was aimed to identify the effects of the change of commuting modes for 8 weeks on physical fitness and cardiovascular risk factors. We recruited volunteers who are sedentary, drive his/her own car for commuting, are aged from 30 to 49, but have no known definite medical diseases. They chose one of three groups respectively: walking, cycling and pubic transportation (PB). Sixty male subjects participated to this study: 19 for walking group, 14 for cycling, and 27 for PT group. In graded exercise test, the resting systolic blood pressure (BP) decreased significantly in walking and PT group (p<0.05), and the resting diastolic BP decreased significantly in walking and cycling group. VO2max increased significantly in all
three groups. In isokinetic strength test, the knee extensor measured in 60 degree/sec speed increased significantly in walking and cycling group. In the physical fitness, hand grip strength increased in cycling group only, back strength and 30sec sit up increased in PT group, one leg standing with eye-closed increased in cycling group. The cardiovascular risk factors in blood such as glucose, Triglyceride, cholesterol, hs-CRP were not changed in all three groups. This study suggest that the change of commuting modes from a private car mode to an active movement mode may increase the volume of physical activities with low-density in daily, which may give positive effect on BP, VO2max, muscle strength in knee extensor and back muscle, and standing balance.
