Abstract:
Purpose:The purpose of this study was to identify the effects of the types of seat surface (static or dynamic seat surface) on the pulmonary functions during prolonged sitting.
Methods:Thirty-four participants (20 males and 14 females) were recruited, and distributed randomly into dynamic prolonged sitting (DPS, n=17) and static prolonged sitting (SPS, n=17) groups. The DPS group was seated on a chair with a dynamic air cushion, and the SPS group was seated on a chair without a dynamic air cushion. The pulmonary function was assessed before sitting, and after participants had been seated for one hour. The pulmonary function [forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and Peak expiratory flow (PEF)] was measured using a spirometer.
Results:Statistical analyses revealed significant differences in the time x group interactions of FVC, FEV1, PEF, and FEV1/FVC. The DPS group were significantly different in FVC, FEV1, PEF, and FEV1/FVC after prolonged sitting for one hour, compared to the SPS group (p<0.05).
Conclusion:These findings suggest that dynamic sitting can prevent a decrease in the physiological function, such as pulmonary functions, rather than static sitting during prolonged sitting.
