Abstract

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.

健康年轻人的走廊和实时 6 分钟步行测试：随机交叉研究

目的心肺耐力对于舒适地参与日常生活活动非常重要。6分钟步行测试（6MWT）等运动测试通常用于评估心肺耐力。我们研究了步态实时分析互动实验室（GRAIL）和基于走廊的 6MWT 对功能表现的影响。A 组参加者进行了走廊 6MWT 训练，然后进行了 1 小时的冲洗。随后，他们进行了基于 GRAIL 的 6MWT 测试。结果与基于 GRAIL 的 6MWT 相比，基于走廊的 6MWT 的 6MW 距离和 6MW 速度明显更高。在收缩压、舒张压、血氧饱和度、心率、呼吸困难和总体疲劳度等次要结果方面，两组之间未发现明显差异。6MW 距离和 6MW 速度之间存在很强的正相关性。
