OBJECTIVES: To determine reference values for the 1-min sit-to-stand (STS) test in an adult population.
METHODS: Cross-sectional study nested within a nationwide health promotion campaign in Switzerland. Adults performed the STS test and completed questions on demographics and health behavior.
RESULTS: 6,926 out of 7,753 (89.3 %) adults were able to complete the STS test. The median number of repetitions ranged from 50/min (25-75th percentile 41-57/min) in young men and 47/min (39-55/min) in young women aged 20-24 years to 30/min (25-37/min) in older men and 27/min (22-30/min) in older women aged 75-79 years.
CONCLUSIONS: The reference values support the interpretation of 1-min STS test performance and identification of subjects with decreased lower body muscular strength and endurance.
