It is known that life style disease is prevented to continuous exercise. In the recent years, the people to exercises are increased from heighten awareness as regard of health. Walking was selected as exercise for health in many cases, to walking technique is easy to practice even for beginners. Improved exercise intensity of walking was reported various researcher, and the nordic walking is one of them. The nordic walking was developed off season training of cross country skier, it was used two poles. In the previous study of the nordic walking, biomechanics and physiological research was reported. However the research of the nordic walking was not yet sufficient. The purpose of this study was investigated to the cardiorespiratory response during the nordic walking. Seven 19-20 years old young healthy men participated in this experience. There physical characteristics were follows: height 169.2 ± 4.4 cm, body weight 65.8 ± 8.3 kg, ; mean ± S.D., respectively. All subjects were free from pain, injury, or any known chronic or acute diseases at the time of this study. The subjects had not been participating in any exercise regularly. Informed consent to participate in this study was obtained by all subjects. Subjects were walked with pole and without on treadmill each 10 minutes. Walking speed was 6 km per hours in each trial. Both trial were chosen at random and performed. Heart rate response and oxygen up take were measured every 30 seconds during walking, and data was analyzed last 1 minute for trial. Statistical processing was used one way repeated measures of analysis of valiance. Statistical significance was accepted at p < 0.05. The result of this experience, heart rate response during the nordic walking was about 6% higher than the normal walking. Also, oxygen up take during the nordic walking was about 9% higher than the normal walking. Consequently, it was suggested that the nordic walking was benefit as health exercise from the normal walking.
