Purpose: Posture correction bands (PCBs) have been proposed as aids to help chest expansion and to enhance respiratory function. However, the impact of PCBs on community-based older individuals engaged in inspiratory muscle training (IMT) at home remains unclear. Materials and Methods: Community-based individuals aged 65 years and older were divided into the PCB group, wearing PCBs, and the NPCB group, not wearing PCBs. The IMT regimen lasted 8 weeks, with sessions 5 times a week, including 4 sets per day and 15 repetitions per set. Training intensity was set at 50% of the maximum inspiratory pressure of each subject. To assess the effects of IMT, respiratory function, 6-minute walk test, and grip strength were measured before, during, and after the training period. Data were analyzed using repeated-measures analysis of variance, with post-hoc evaluation employing Bonferroni correction. Results: A total of 40 subjects were evenly divided into the PCB group and the NPCB group, with 20 subjects in each group. No significant difference was observed in respiratory muscle strength based on PCB use. However, during the initial 4 weeks, the PCB group exhibited a trend towards an increase in respiratory muscle strength compared to the NPCB group; this trend, however, did not prove to be statistically significant by the end of the 8-week period. Performance on the 6-minute walk test significantly improved in both groups. Conclusion: The PCB group exhibited a tendency for increase in respiratory muscle strength in the first 4 weeks; however, ultimately there was no significant difference compared to the NPCB group. Clinical Trial Registration: This study was registered with the Clinical Research Information Service, part of the World Health Organization’s International Clinical Trials Registry Platform (Clinical Research Information Service No. KCT0008075).
