Purpose : This study aimed to analyze cardiopulmonary function according to different smartphone usage postures, such as upright sitting, slumped sitting, side-lying, and prone. Methods : A total of 82 college students participated (54 males and 24 females). The forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), central venous oxygen saturation (SVC), and peripheral oxygen saturation (SpO2) were measured using a portable spirometer (Pony FX) in four different postures commonly adopted while using a smartphone (upright sitting, slumped sitting, side-lying, and prone) randomly. One-way repeated-measures analysis of variance was performed to determine the difference among the four postures. If a significant difference by posture was found, the Bonferroni test was performed as a post-hoc. Results : Significant differences were found in the lung function variables of FVC, FEV1, and FEV1/FVC on body positions (p<.05). The post-hoc analysis revealed that the FVC was lower in the side-lying and prone positions than in the upright and slumped sitting positions (p<.0125). The FEV1 was lower in the side-lying and prone positions than in the upright sitting and slumped sitting positions and was lower in the side-lying position than in the prone position (p<.0125). The FEV1/FVC was lower in the side-lying position than in the upright sitting position (p<.125). Conclusion : When using a smartphone, a sitting position that helps improve lung capacity and breathing efficiency, induces less pressure on the chest, does not restrict movements of the diaphragm, and is freer than in a prone or side-lying position is suggested.
