The relationship of sit-to-stand tests with 6-minute walk test in healthy young adults
MetadataShow full item record
The aim of this study was to evaluate the timed sit-to-stand (STS) test performances of healthy young adults and to investigate the relationship of timed STS tests with 6-minute walk test (6MWT). A cross-sectional study was performed. A total of 40 healthy volunteers (mean age: 21.7 +/- 1.2 years) were evaluated with 10, 30, and 60seconds STS tests and 6MWT. Fatigue and shortness of breath were rated using Borg category-ratio scale (CR10) before and after each test. Weekly energy expenditures of volunteers were calculated using International Physical Activity Questionnaire. 30 and 60seconds STS tests were moderately (r=0.611 and r=0.647, respectively) (P.05). Borg fatigue scores after 10, 30, and 60seconds STS tests were weakly correlated with fatigue score after 6MWT (r=0.321, r=0.378, and r=0.405, respectively) (P<.05). Weekly energy expenditure (MET-min/week) was moderately correlated with 10, 30, and 60seconds STS tests and 6MWT (r=0.533, r=0.598, r=0.598, and r=0.547, respectively) (P<.001). Considering the statistically significant relationship between timed STS tests and 6MWT, any of the timed STS tests may be used for a quick and alternative measurement of physical performance and functional capacity in healthy young adults.
