Effects of different exercises on respiratory parameters: A randomized controlled trial

This study was designed to compare the effects of core stabilisation (CS) and auxiliary respiratory muscle strengthening exercises on oxygen consumption and respiratory parameters. A total of 51 participants were divided into three groups with block randomization method according to age and gender: CS Group (n = 17), Auxiliary Respiratory Muscles Exercise (ARM) Group (n = 17) and Control (C) Group (n = 17). Maximum oxygen uptake (VO₂max), first second of forced expiration (FEV1)/Forced vital capacity (FVC) and maximal voluntary ventilation (MVV) values were evaluated before and after the study. CS and ARM strengthening exercises were applied 3 days a week for 6 weeks. The increase in the FEV1/VC values was higher in the CS and ARM groups than in the C group (p < 0.05), whereas no statistically significant difference was observed between the ARM and CS groups (p < 0.05). There was no statistically significant difference between the groups in terms of VO₂max values before and after the study (p > 0.05). The increase in the MVV values was higher in the CS and ARM groups than in the C group (p < 0.05), whereas no statistically significant difference was observed between the ARM and CS groups (p > 0.05). CS and ARM exercises had positive effects on FEV1/FVC and MVV.
