OBJECTIVE
Cardiopulmonary endurance is important for comfortably participating in activities of daily living. Exercise tests, such as the 6-minute walk test (6MWT), are commonly used to evaluate cardiopulmonary endurance. We investigated the effects of the Gait Real-Time Analysis Interactive Lab (GRAIL)- and corridor-based 6MWTs on functional performance.
METHODS
Thirty healthy men were randomly divided into two groups. Group A participants performed a corridor-based 6MWT, followed by a washout period (1 h). Subsequently, they performed the GRAIL-based 6MWT. Group B participants performed the tests in the reverse order of that performed by Group A participants.
RESULTS
The corridor-based 6MWT resulted in significantly higher 6MW distance and 6MW speed than the GRAIL-based 6MWT. No significant differences were observed between the two groups in any of the following secondary outcomes: systolic blood pressure, diastolic blood pressure, oxygen saturation, heart rate, dyspnea, and overall fatigue. A strong positive correlation was observed between the 6MW distance and 6MW speed.
CONCLUSION
The corridor- and GRAIL-based 6MWT should not be used interchangeably.
目的
心肺耐力对于舒适地参与日常生活活动很重要。运动测试，如6分钟步行试验（6MWT），常用于评估心肺耐力。我们研究了基于步态实时分析互动实验室（GRAIL）和走廊的6MWT对功能表现的影响。
方法
30名健康男性被随机分为两组。A组参与者先进行基于走廊的6MWT，随后有一个洗脱期（1小时）。之后，他们进行基于GRAIL的6MWT。B组参与者按照与A组参与者相反的顺序进行测试。
结果
基于走廊的6MWT比基于GRAIL的6MWT产生的6MW距离和6MW速度显著更高。在以下任何次要结果中，两组之间均未观察到显著差异：收缩压、舒张压、血氧饱和度、心率、呼吸困难和总体疲劳。6MW距离和6MW速度之间观察到强正相关。
结论
基于走廊和GRAIL的6MWT不应互换使用。
