Cut-Off Points for Low Relative 30-s Sit-to-Stand Power and Their Associations With Adverse Health Conditions

Abstract

Despite muscle power derived from the 5-rep sit-to-stand (STS) test having been demonstrated to be a valuable biomarker in older individuals, there is limited information regarding muscle power derived from the 30-s STS test, a widely used test in the clinical setting. This study aimed (i) to compare relative 30-s STS power values between older men and women, (ii) to identify cut-off points for low relative 30-s STS power, (iii) to compare the prevalence of low relative STS power between sexes and (iv) to evaluate the association of low relative 30-s STS power with adverse conditions in older people.
