Purpose: The purpose of this study was to investigate the effect of chest mobilization and stretching exercises on maximalinspiratory pressure and maximal expiratory pressure in healthy adults who use computers for extended periods of timeeach day due to coronavirus disease 2019.
Methods: Twenty-five healthy adults in their 20s and without respiratory disease (15 female, 10 male) took part in thisstudy. Two types of thoracic mobilizing exercises using a Theraband and three types of stretching exercises using afoam roller were performed. Maximum inspiratory pressure and maximum expiratory pressure were measured three timeseach before and after the interventions. In terms of statistical methods, the maximum inspiratory pressure due to chestmobility and stretching was compared with the maximum expiratory pressure using parametric paired t-test and non-parametricWilcoxon signed-rank test.
Results: Maximum inspiratory pressure (p = .012) and maximum expiratory pressure (p = .006) showed significant differencesbefore and after chest mobilization exercise and stretching among the participants.
Conclusion: The results of this study suggest that chest mobilization and stretching exercises are effective exercise methodsfor improving maximal inspiratory and expiratory pressure. They suggest that these exercises can prevent respiratorymuscle weakness and improve aerobic fitness in healthy people as well as those in need of cardiorespiratory physiotherapy.
