2型糖尿病患者を対象として、短時間の階段昇降運動による血糖コントロール改善効果を検討した。食後90分に行う8~10分間、及び食後60分と120分に行う3分間の階段昇降運動は食後高血糖を急性的に緩和した。階段昇降運動と自転車運動を同じ心拍数で行ったところ前者でより急性的な血糖降下が得られた。さらに自宅内で毎食60分後と120分後に3分間の階段昇降運動を2セットずつ行うことで24時間にわたる血糖コントロールが改善するとともに、この運動を2週間継続することで血糖コントロール指標(血中1,5-アンヒドログルシトール)が改善した。以上より、階段昇降運動の2型糖尿病治療における臨床的有用性が示唆された。

This study compares the physiological work load between two ascending patterns, single-step (SS) and double-step (DS), when climbing a public staircase at the two different climbing rates, controlled speed (105steps/min) and free speed. The SS pattern involved climbing one step at a time, while the DS pattern involved climbing two steps in a single stride. Thirteen female subjects climbed a typical 7-storey building, giving a total of 168 steps and vertical movement of 27.7 m. The results for perceived exertion (RPE), blood lactate level, oxygen consumption and muscle EMG activity were significantly higher (p < 0.05) with the DS than SS pattern at a controlled speed. The results also showed that the ascending speed, heart rate, blood lactate level, respiratory quotient (RQ) and RPE were significantly higher (p < 0.05) with the DS than SS pattern at a free speed. These results clearly indicate the higher physical workload involved with the DS than SS pattern at both free and controlled speeds.

This study evaluated the exercise profile (heart rate, cycling speed and pedal cadence) during 25-30 km cycling and fitness and health level for adults (11 males: 69.6 ± 4.7 yrs; 6 females: 66.3 ± 4.9 yrs) with a recreational cycling habit (27.6 ± 14.8 km/week). Exercise intensity at a constant speed on a flat road during male and female cycling was 71.2 ± 11.5 and 66.8 ± 11.4% heart rate reserved (HRR), respectively. Exercise intensity over 60% HRR occupied 72% of cycling time. Peak intensity during male and female cycling was 89.2 ± 8.9 and 93.1 ± 6.1% HRR, respectively. VO2max and CS (chair stand)-30 test for male and female were 40.3 ± 4.3 and 37.7 ± 2.4 ml/kg/min, and 30.8 ± 3.1 and 30.1 ± 3.2 times, respectively. The muscle cross-sectional area of thigh extensor and flexor measured by MRI were 55.4 ± 6.5 and 58.3 ± 13.3 cm2 for male, and 45.5 ± 6.4 and 50.2 ± 5.7 cm2 for female, respectively. Blood profile for HDL-C (cholesterol), LDL-C and HbA1c (JDS) for male and female were 65.9 ± 8.2 and 67.9 ± 10.6 mg/dl, 112.3 ± 32.0 and 130.6 ± 12.3 mg/dl, and 4.8 ± 0.4 and 4.7 ± 0.1%, respectively. Fitness level and blood profile results were superior to those of the same aged adults. We concluded that the exercise intensity of cycling by middle and older adults with a recreational cycling habit is high and their fitness and health level are higher than average adults.
