| Abstract |
Purpose: The study aimed to analyze the effect of chest-expansion exercise studies on chest expansion, respiratory function, and functional activity over the past 8 years (2015–2022). Methods: Previous studies were electronically searched using the PubMed, PEDro, KISS, and RISS4U databases. A total of five studies were selected according to the PRISMA guidelines, and the PEDro scale was used for the qualitative analysis. Results: Five studies met the criteria. Two studies scored 6 of 10 and three scored 5. Four studies had an intervention of 20 and 30 min, each at a frequency of
4–5 times per week, for a total of 4–8 weeks, except for one study that performed 20 min of intervention at a time, which demonstrated an immediate effect. The results indicated that chest-expansion exercises effectively improved chest expansion, respiratory function, and functional activity. Conclusion: Chest-expansion exercises exert positive effects on chest expansion, respiratory function, and functional activity. |
