Reference Value for the Distance Walked in the Six-Minute Walk Test in Obese Brazilian Men in the Preoperative Period of Bariatric Surgery

Table 1

Anthropometric and demographic data, lung function, and six-minute walk test results of the evaluated sample.

Variables	Values (n = 104)
Anthropometric and demographic variables
Age (years)	41.4 ± 12.2
Weight (kg)	146.5 ± 27.5
Height (m)	1.74 ± 0.1
BMI (kg/m^2)	48.1 ± 8.4
Lung function
FVC (% predicted)	83.5 ± 16.1
PEF (% predicted)	90.1 ± 21.1
FEV1/FVC (%)	85.4 ± 6.5
MIP (% predicted)	95.3 ± 12.8
MEP (% predicted)	85.4 ± 13.3
Six-minute walk test
6 MWD (m)	439.2 ± 82.7

The results are expressed as the means ± SD; BMI: body mass index; FVC: forced vital capacity; PEF: peak expiratory flow; FEV₁: forced expiratory volume in one second; MIP: maximal inspiratory pressure; MEP: maximal expiratory pressure; 6 MWD: six-minute walk distance.
