Peak XXXX uptake during the incremental shuttle walk test in a predominantly female population with @entity299 .

@entity1 @entity26 @entity299
BACKGROUND: @entity299 ( @entity299 ) @entity1 may have a reduced functional capacity (FC). Field tests, as the Incremental Shuttle Walk Test (ISWT), can estimate peak @entity26 uptake (VO2 peak). However, the relationship between the ISWT and the Cardiopulmonary Exercise Testing (CPET), the gold standard in the assessment of FC, is not well established in @entity299 @entity1 . AIM: This study aimed to evaluate the FC of @entity299 @entity1 by ISWT with direct measurement of VO2 peak and to compare these findings with data obtained from CPET. A secondary goal was to derive a regression equation to calculate the VO2 peak by ISWT. DESIGN: Cross-sectional and correlative study. SETTING: Research laboratory setting. POPULATION: Thirty-two @entity299 @entity1 (58.8  9.0 years, 81.3% @entity1 ) participated in this study. METHODS: Eligible @entity1 underwent clinical evaluation, echocardiography, CPET by ramp protocol and ISWT according to current guidelines. RESULTS: The distance walked in ISWT showed a positive correlation with VO2 peak from CPET and ISWT (r=0.456, p=0.009 and r=0.869, p<0.001, respectively). In the agreement analysis, the values of the differences between VO2 peak from CPET and ISWT showed absence of bias (mean bias    95% CI and mean -1.29    5.09mL.kg.min). Based in real values of VO2 obtained from ISWT, one equation including sex, functional class and distance walked was provided to predict the VO2 values in this test. CONCLUSION: This study showed the good correlation between distance walked in ISWT and VO2 peak directly measured in both tests, and additionally, provided an equation to calculate a predictive VO2 peak by ISWT, suggesting a good alternative to evaluate the FC of @entity299 @entity1 , especially in locations where sophisticated testing is not available. CLINICAL REHABILITATION IMPACT: The results confirm the possibility of using the ISWT for the evaluation of the FC in @entity1 with @entity299 , especially in locations where sophisticated testing is not available.
