Inspiratory and expiratory muscle strength were inversely associated with frailty and pre-frailty. Cut-off points ≥-50cmH2O and ≤60cmH2O for maximum inspiratory and expiratory pressures, respectively, were established as optimal discriminators of frailty. The cut-off point ≤65cmH2O for maximum expiratory pressure was established as a discriminant for the presence of pre-frailty. Conclusions Inspiratory and expiratory muscle strength were lower in frail than in pre-frail older adults, and lower in pre-frail than in non-frail peers. Frailty and pre-frailty we
