İnspiratuar Kas Kuvvetinin Aerobik ve Anaerobik Performans Değişkenleri ile İlişkisi

Although it is known that respiratory muscle strength training has positive effects on aerobic and anaerobic power, very few studies examine the correlation with potential variables related to respiratory muscle strength. This study aims to test the relationship between respiratory muscle strength and aerobic and anaerobic power. The secondary objective is to evaluate its relationship with body composition and respiratory function test results. Twenty-three physically active male volunteers (age=21.13±2.46years, height=177.39±6.08cm, weight=74.83±12.52kg) from Erciyes University Faculty of Sports Sciences participated in this study. The test of inspiratory muscle strength by a Powerbreathe K5-device, maximal oxygen consumption (maxVO2) by a 20-m shuttle-run test, respiratory function tests by a spirometer, and 30-second Wingate anaerobic power tests were performed. The correlation between variables was examined by Pearson and Spearman correlation analyses. No significant correlation was found between S-index and body fat-mass(r=-0.049), body fat-percentage(r=-0.038), fat-free mass(r=0.251), and body mass index (r=0.118)(p>0.05). While S-index was found to have a moderately significant relationship with maxVO2 (46.63±6.14 ml/kg/min)(p=0.027, r=460), it has no significant relationship with HRrest (85.5±10.5 beats/min)(r=0.281), Lactaterest (1.32±0.51 mmol/L)(r=0.186), and HRtest-end (184.6±17.57 beats/min)(r=0.096) and Lactatetest-end (11.4±2.58 mmol/L)(r=0.155) values measured immediately end of the shuttle-run test. S-index value showed a strong significant correlation (p
