Muscle power predicts frailty and other adverse events across different settings

Lower-limb MP is a valid clinical biomarker associated with frailty and negative health events in older adults. The degree of associations varied according to frailty scale and clinical context, but no significant differences were observed when we compared their predictive ability. The proposed MP cut-off points may enhance frailty assessment and screening, particularly in primary care, nursing homes, and outpatient clinics. These findings highlight the clinical potential of incorporating MP measures into frailty tools and stress the need for further research to refine age-specific cut-off points and explore the influence of body composition.
