10 大阪総合保育大学紀要第 9 号 2014 Exercise Intensity of Nordic Walking with the Change of Inclination Angles Atsushi Takahashi*,Akiko Ikeshima**,Sayaka Tomokane**,Jiro Toyooka** *Osaka University of Comprehensive Children Education **Osaka University of Health and Sports Sciences English abstract For 10 college boys (mean age: 21) with higher physical fitness level who performed Nordic walking and normal walking on a treadmill by various inclination angles, we measured oxygen intake, METs and heart rate and examined the exercise intensity of the both walking styles. As a result of comparison in oxygen intake, METs and heart rate between Nordic walking and normal walking by an angle of 0%, all items were significantly higher in Nordic walking by 6 to 7%. In this setting, the exercise intensity of Nordic walking corresponded to 37% of V 4 O 2 max and 53% of HRmax, being unable to the minimal threshold. According to METs scale, it was corresponded to Vigorous in ACSM classification table by an angle of 6% or higher. It has been suggested that intensity of Nordic walking is required for 4 to 5km of training distance by an angle of 6% or larger to enhance cardiorespiratory and calorie expenditure systems. Key words : Nordic walking, METs, %HRmax, %V 4 O 2 max, Calorie expenditure
