Correlation Between the 1‐Minute Sit-to‐Stand Test and 6‐Minute Walk Test in Healthy Young Adults

Background: The 6-min walk test (6 MWT) is widely used to assess submaximal aerobic capacity; however, it requires a long corridor and considerable time to administer. The 1-min sit-to-stand test (1 MSTS) has been proposed as a quick and space-efficient alternative for evaluating functional exercise capacity. This study aimed to examine the performance of healthy young adults on the 1 MSTS test and determine its correlation with the 6 MWT distance. Methods: Ninety healthy volunteers aged 18–25 years participated in this cross-sectional study. Participants underwent one 6-MWT and one 1-MSTS test on a standard chair with arms crossed, in accordance with the American Thoracic Society guidelines. Dyspnea and leg fatigue were rated using the Borg CR-10 scale before and after each test. The association between 1 MSTS test repetitions and 6 MWT distance was assessed using Spearman’s correlation. Gender differences and the relationship between age and test outcomes were also analyzed. Results: The participants completed an average of 49 ± 8 sit-to-stand repetitions and walked 618 ± 85 m during the 6 MWT. A moderate positive correlation was observed between 1 MSTS test repetitions and 6 MWT distance (ρ ≈ 0.65, p < 0.001). Men performed slightly better than women in both tests, whereas age within the 18–25-year range showed no significant association with performance. Conclusion: The 1-minute sit-to-stand test showed a moderate association with the 6-minute walk test in healthy young adults and may serve as a practical alternative for assessing functional exercise capacity when the 6 min walk test is not feasible.
