AI Article Synopsis
- The study investigates how different types of exercise tests, specifically the corridor-based and GRAIL-based 6-minute walk tests (6MWT), affect cardiopulmonary endurance in healthy men.
- Results showed that the corridor-based 6MWT led to better performance in terms of distance and speed compared to the GRAIL-based test, with no significant differences in other health metrics.
- The researchers conclude that these two testing methods should not be used interchangeably for assessing cardiopulmonary endurance.
Article 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.
