Healthy subjects without exercise habit that can cooperate with the measurements of this study, loaded inspiratory muscle test.
Other: Loaded inspiratory muscle test
Loaded inspiratory muscle tests will be set at 30% of maximal inspiratory pressure in sitting and supine positions. The orders of the two loaded test conditions will be conducted in random order with at least 20 minute separation. This is an observational study. Subjects will perform only 15 breaths with each loaded test condition to exam the performance of their inspiratory muscles. Loaded inspiratory muscle test is not for training.
- Diaphragm and Sternocleidomastoid muscle activation [ Time Frame: Through the completion of the loaded inspiratory muscle test condition; it would take about 3 minutes ]Root mean square values during different conditions
- The mean median frequency of diaphragm and sternocleidomastoid muscle [ Time Frame: In one minute after the completion of the loaded inspiratory muscle test condition ]The power spectrum is divided into two equal areas of the frequency value by median frequency to exam muscle fatigability
