Assessment of Inspiratory Muscle Endurance in Healthy Adults by Recording Breathing Characteristics

Respiratory muscle function is considered as strength and endurance. Since respiratory muscles are used a submaximally in daily life, measurement of respiratory muscle endurance rather than respiratory muscle strength is a more functional assessment. Measurement of respiratory muscle endurance is recommended to be performed by controlling the respiratory frequency and recording the breathing parameters. The purpose of this study was to evaluate respiratory muscle endurance with the incremental threshold loading (ITL) test in healthy adults by recording breathing parameters.
