About this trial
Mandibular stretching exercises and breathing techniques may influence autonomic nervous system activity, muscle tone, and psychological state. This randomized controlled trial aims to investigate the effects of mandibular stretching exercise and the 4-4-8 breathing exercise on autonomic nervous system activity, muscle tone, and psychological parameters in healthy university students. Participants will be randomly assigned to intervention groups and evaluated before and after the intervention period.

Trial outcomes
Primary outcomes
1
Autonomic Nervous System Activity
Autonomic nervous system activity will be assessed by measuring heart rate (beats per minute) using a digital pulse oximeter and blood pressure (mmHg) using an automatic blood pressure monitor. Measurements will be recorded at baseline and repeatedly after the intervention period (20, 40, 80, and 120 minutes).
Time frame
Baseline and 20, 40, 80, and 120 minutes after the interventionSecondary outcomes
1
Muscle Tone
Muscle activity of the temporalis and masseter muscles will be assessed using surface electromyography (EMG). EMG amplitude (microvolts, µV) will be recorded at baseline and repeatedly after the intervention period (20, 40, 80, and 120 minutes).
Time frame
Baseline and 20, 40, 80, and 120 minutes after the intervention2
Psychological State
Psychological state will be assessed using the State-Trait Anxiety Inventory (STAI) questionnaire. STAI scores (range 20-80 points) will be recorded at baseline and repeatedly after the intervention period (20, 40, 80, and 120 minutes).
