Characteristics of the sample.

Variables	N = 35
Gender (M/F)	17/18
Age (years)	69 ± 9
BMI (kg/m^2)	26 (24–28)
FEV1/FVC (%)	47 ± 10
FEV1 (liters)	0.76 (0.64–1.02)
FEV1 (% predicted)	34 (24–52)
FVC (liters)	1.69 (1.28–2.17)
FVC (% predicted)	58 (43–79)
Fried scale	7 (5–9)
Non frail (%)	0 (0)
Pre frail (%)	6 (17)
Frail (%)	29 (83)
Edmonton scale	3 (3-4)
Non frail (%)	7 (20)
Pre frail (%)	10 (29)
Frail (%)	18 (51)

Values were described as mean ± standard deviation or median (interquartile range 25–75%); Shapiro–Wilk test was used to test normality and value >0.05 indicates normal distribution. M: male; F: female; BMI: body mass index; FEV₁: forced expiratory volume in the first second; FVC: forced vital capacity.
