Clinical Trial Summary

The aim of this study is to determine the reference value ranges for healthy adults of the incremental threshold load test, which evaluates respiratory muscle endurance.

Description:

Since respiratory muscles are used in daily life at the submaximal level, evaluation of their endurance is more meaningful functionally. In addition, evaluation of endurance with respiratory muscle strength is effective in determining respiratory muscle dysfunction. Failure to routinely evaluate respiratory muscle endurance, which is one of the main components of respiratory muscle function, may lead to failure to identify respiratory muscle dysfunction in early stage respiratory patients who have not yet developed muscle strength loss. However, normal value ranges have not been determined for the respiratory muscle endurance test.

Determining the normal value ranges for this test will help determine muscle fatigue and investigate the physiological course in respiratory diseases.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Anthropometric assessment	Body weight was assessed with a digital scale in the orthostatic position, without shoes, with minimal clothing. Height was measured with the feet parallel and adjacent to each other, the arms extended by the body, and the head in a neutral position. Correlations between inspiratory muscle endurance of the incremental threshold loading protocol and anthropometric characteristics will be shown.	5 minute
Primary	Incremental threshold loading test.	A measure of endurance of inspiratory muscles.	15 minute
Primary	Maximal inspiratory pressure	A measure of the strength of inspiratory muscles	20 minute
Secondary	Pulmonary function test - Forced expiratory volume in 1 second (FEV1)	The forced expiratory volume in 1 second (FEV1) is the volume of air (in liters) exhaled in the first second during forced exhalation after maximal inspiration. It is lung function test that are measured during spirometry. This pulmonary function test measurements were made to confirm that the respiratory function parameters of the participants were within the normal range. .	5 minute
Secondary	Pulmonary function test - Forced vital capacity (FVC)	Forced vital capacity (FVC) is lung function test that are measured during spirometry. This pulmonary function test measurement is applied to confirm that the respiratory function parameters of the participants were within the normal range.	5 minute
Secondary	Maximal voluntary ventilation (MVV)	It is a test that measures inspiratory endurance. MVV is the largest amount of air that a person can inhale and then exhale during a 12- to 15-s interval with maximal voluntary effort. It is determined by spirometry measurement.	5 minute
Secondary	International Physical Activity Questionnaire - Short Form	This questionnaire assesses the types of intensity of physical activity and sitting time that people do as part of their daily lives are considered to estimate total physical activity in the metabolic equivalent of task (MET)-minute/week and time spent sitting.	5 minute
