Effect of Upright and Slouched Sitting Postures on the Respiratory Muscle Strength in Healthy Young Males

Table 1

Participant’s characteristics and baseline data.

Variables	Mean (SD)
Age (years)	22.5 (5.6)
Height (m)	1.7 (.05)
Weight (kg)	74.6 (16.04)
Body mass index (kg/m^2)	25.6 (4.04)
(cmH2O)	93.5 (25.8)
(cmH2O)	84.8 (22.5)
PEF (%)	.90 (.13)
FVC% predicted	.85 (.09)
FEV1% predicted	.98 (.13)
FEV1/FVC ratio	115.7 (17.7)

PEF: peak expiratory flow; FVC: forced vital capacity; FEV1: forced expiratory volume in one second; : sniff nasal inspiratory pressure in upright sitting; : sniff nasal inspiratory pressure in slouched sitting.
