Article Changes in Respiratory Muscle Pressure of Healthy Individuals With Different Levels of Immersion in Water: Observational Study(Dokuz Eylul Univ Inst Health Sciences, 2023-09-30) Gurpinar, Baris; Özyürek, Seher; Elvan, Ata; Tükel, ŞerminPurpose: Understanding the physiological effects of immersion, particularly on pulmonary dynamics in healthy individuals is important to predict and interpret the physiological responds in unhealthy group. The aim of our study is to evaluate the inspiratory and expiratory muscle strength and cough strength in healthy individuals during water immersion at different water depths. Methods: A cross-sectional study was conducted in 24 healthy individuals with the mean age 20.0 years. Respiratory muscle strength test and cough force were tested on dry land and in pool at iliac crests, xiphoid appendix of the sternum and clavicles levels. Measurements were randomized at each level. The Friedman test was used for repeated measures with Wilcoxon signed ranks test with Bonferroni correction was applies to compare the variables. Results: A significant difference between dry land and immersion in water of different levels for MEP (p=0.001) and PEF (p= 0.015). Multiple comparisons showed no difference between levels in PEF (p<0.001), whereas MEP values measured in clavicles level was significantly higher than both dry land and iliac crest level (p<0.0125). Conclusion: Clavicle level immersion alters respiratory muscle strength when compared with the values measured out of the water and immersed at the iliac crest level in healthy individuals.Article Citation - WoS: 3The Effects of Respiratory Muscle Functions on Trunk Muscle Endurance in Healthy Young Adults(Dokuz Eylul Univ Inst Health Sciences, 2023-05-31) Aktan, Özge Ocaker; Aktan, Rıdvan; Yakut, Hazal; Yakut, Hazal; Ozalevli, Sevgi; Kara, Bilge; Ocaker Aktan, OzgePurpose: Respiratory muscles play a dual role in breathing and trunk stability during activities. The relationship between respiratory muscle functions and trunk stability has not yet been clarified. The aim of the study was to examine the effects of respiratory muscle functions on trunk muscle endurance in healthy young adults. Methods: McGill's trunk muscle endurance tests, which consist of trunk flexion endurance test (FE), Sorensen test (ST) and Side Bridge test (SB), were used to evaluate the participants' trunk muscle endurance. Respiratory muscle strength was evaluated by measuring intraoral maximal inspiratory and expiratory pressures using an intraoral pressure meter device. The respiratory muscle endurance test was performed with the incremental threshold load protocol using a threshold IMT device. Results: A total of 51 healthy young adults, with a mean age of 21.8 ± 3.2 years, were evaluated. The results of the linear regression models were significantly explained 46% of the variance in the SB and 38% in the FE, (for SB Adj R2=0.46, F=21.40, p< 0.001 and for FE Adj R2=0.38, F=15.65, p< 0.001). Respiratory muscle endurance contributed 30% to the endurance of the trunk flexor muscles, while respiratory muscle strength contributed only 8%. Similarly, respiratory muscle endurance contributed 38% to the endurance of the trunk lateral flexor muscles, while respiratory muscle strength contributed only 8%. Conclusion: Although respiratory muscle strength and respiratory muscle endurance were independent contributors to trunk muscle endurance, respiratory muscle endurance more affected trunk muscle endurance than respiratory muscle strength in healthy young adults.
