UNASSIGNED: We assessed the validity of the submaximal 6-minute walk test (6MWT) as a measure of aerobic capacity compared to a maximal treadmill test and the submaximal Gerkin protocol.
UNASSIGNED: Twenty-four firefighters (19 male, 5 female, 34.8 ± 9.7 years; 38.1 ± 3.6 kg·m-2) completed the 6MWT, the submaximal Gerkin protocol, and a maximal treadmill test. Data were analyzed with Bland-Altman plots and correlation analysis.
UNASSIGNED: We found equivalence between the 6MWT and directly measured VO2max and between the 6MWT and Gerkin protocol using Bland-Altman plots. In our cohort, the 6MWT underestimated VO2max (31.57 ml·kg-1·min-1) compared to directly measured VO2max (38.1 ml·kg-1·min-1) by 17% and to the Gerkin (40.48 ml·kg-1·min-1) by 22%.
UNASSIGNED: Considering its equivalence, using the 6MWT could be a more accessible way to quantify aerobic capacity in firefighters. Despite underestimation, having an easy to administer protocol may encourage more fire stations to assess pre- and post- fitness levels regularly.
■我们评估了与最大跑步机测试和亚最大Gerkin方案相比,亚最大6分钟步行测试(6MWT)作为有氧能力度量的有效性。
■24名消防员(19名男性,5女,34.8±9.7年;38.1±3.6kg·m-2)完成6MWT,次最大的Gerkin协议,和最大跑步机测试。数据采用Bland-Altman图和相关分析进行分析。
■我们发现了6MWT与直接测量的VO2max之间以及使用Bland-Altman图的6MWT与Gerkin协议之间的等效性。在我们的队列中,与直接测量的VO2max(38.1ml·kg-1·min-1)和Gerkin(40.48ml·kg-1·min-1)相比,6MWT低估了VO2max(31.57ml·kg-1·min-1)为22%。
■考虑到它的等价性,使用6MWT可能是一种更容易量化消防员有氧能力的方法。尽管低估了,有一个易于管理的协议可能会鼓励更多的消防局定期评估前和后健身水平。
