The purpose of this study was to evaluate the reliability, reproducibility, and validity of the 6-minute walk test and step test as substitutes for ergometer exercise in patients with type 2 diabetes mellitus.
The study included 54 women aged 50-70 years who had type 2 diabetes mellitus. All the patients performed a cycle ergometer-graded exercise test for cardiorespiratory fitness (V̇O2max), followed by 6-minute walk and step tests.
The mean distance covered during the 6-minute walk test was 538 ± 54 m, and the mean recovery heart rate after the step test was 93 ± 11 beats/min. A significant correlation was found between the distances covered during the cardiorespiratory fitness test (V̇O2max) and those covered the 6-minute walk test (r = 0.542, p < 0.01) and step test (r = -0.490, p < 0.01) in the patients with type 2 diabetes mellitus. Regression equations for the prediction of V̇O2max were constructed from the distance covered, heart rate, age, weight, height, fasting blood glucose level, 2-hour postprandial glucose level, and glycated hemoglobin level during the 6-minute walk test and step test.
The 6-minute walk and step tests are simple to perform and reliable for the evaluation of cardiorespiratory fitness in patients with type 2 diabetes mellitus.
本研究旨在评估6分钟步行试验和台阶试验作为2型糖尿病患者测力计运动替代方法的可靠性、可重复性和有效性。
该研究纳入了54名年龄在50 - 70岁之间的2型糖尿病女性患者。所有患者均进行了用于评估心肺适能（最大摄氧量）的自行车测力计分级运动试验，随后进行6分钟步行试验和台阶试验。
6分钟步行试验期间的平均行走距离为538 ± 54米，台阶试验后的平均恢复心率为93 ± 11次/分钟。在2型糖尿病患者中，心肺适能试验（最大摄氧量）期间的行走距离与6分钟步行试验（r = 0.542，p < 0.01）和台阶试验（r = -0.490，p < 0.01）期间的行走距离之间存在显著相关性。根据6分钟步行试验和台阶试验期间的行走距离、心率、年龄、体重、身高、空腹血糖水平、餐后2小时血糖水平和糖化血红蛋白水平构建了预测最大摄氧量的回归方程。
6分钟步行试验和台阶试验操作简单，对于评估2型糖尿病患者的心肺适能具有可靠性。
