Comparison of Intercostal and Quadriceps Femoris Muscle Oxygenation in Women and Men

The differences in physiological responses due to gender during exercise tests have recently begun to be investigated. The oxygen use of respiratory muscles and lower extremity muscles may differ during upper and lower extremity exercise tests, but there is no study on this subject in the literature. The primary aim of this study was to compare intercostal and quadriceps femoris muscle oxygenation during upper extremity and lower extremity maximal exercise tests in women and men. The secondary aim of the study was to investigate the relationship between intercostal and quadriceps femoris muscle oxygenation and upper extremity and lower extremity exercise capacity, body composition, respiratory muscle strength, and respiratory muscle endurance in women and men.
