Low relative sit-to-stand power in Colombian older adults: Cut-off points and associations with frailty and functional decline

Relative STS power is a simple, clinically feasible biomarker to identify functional impairment in older adults. The sex-specific thresholds reported for Colombian populations reflect demographic differences in muscle physiology and decline. Their integration into geriatric practice may enhance early detection, guide preventive interventions, and ultimately improve health outcomes in aging populations.
