Abstract
|
|
|
Objectives: The aim of this study was to determine whether exercises can change the cervical angle and respiratory function in smartphone users.
Methods: Thirty healthy volunteers were recruited. The subjects were randomly divided into an exercise group and a control group. All participants used a smartphone for 1 hour while maintaining a sitting posture. Then, each group performed their assigned activity. The exercise group performed two types of exercises and the control group maintained routine activities for 20 minutes. To investigate the changes in cervical angle and respiratory function, we measured the craniovertebral angle by using a spirometer.
Results: Statistically significant differences were noted in the craniovertebral angle, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak expiratory flow, maximal inspiratory pressure, and maximal expiratory pressure of the two groups (p < 0.05).
Conclusion: Our findings showed that proper exercise could be a good method of improving the cervical angle and respiratory function in smartphone users.
