Outcome Measures

Primary Outcomes (3)

  • Autonomic Nervous System Assessment

    To assess the autonomic nervous system, heart rate variability will be evaluated. A Polar H9 heart rate sensor chest strap and Elite HRV software will be used to measure analytical heart rate variability. During the assessment, the participant will be in a seated position in a chair, the Polar system chest strap will be placed directly over the sternum, and ultrasound gel will be used to increase the conductivity of the sensor. This method has validity with electrocardiogram. Heart rate variability parameters such as RMSSD, PNN50, and LF/HF will be measured.

    Baseline, and at 0, 10, and 20 minutes after the 20-minute exercise session.

  • Pulse Measurement

    Pulse measurements will be performed using an Omron brand digital blood pressure monitor. Individuals will be rested for at least 5 minutes before the measurement to ensure relaxation for an accurate reading.

    Baseline, and at 0, 10, and 20 minutes after the 20-minute exercise session.

  • Blood Pressure Measurement

    Blood pressure measurements will be performed using an Omron brand digital blood pressure monitor. Individuals will be rested for at least 5 minutes before the measurement to ensure relaxation for an accurate reading.

    Baseline, and at 0, 10, and 20 minutes after the 20-minute exercise session.

Secondary Outcomes (1)

  • Oxygen Saturation

    Baseline, and at 0, 10, and 20 minutes after the 20-minute exercise session.

Study Arms (3)

Control Group(CG)

NO INTERVENTION

The control group will not receive any intervention. Participants in this group will be asked to sit comfortably in a chair for a single 20-minute session. Individuals will be provided with an environment where disturbing factors (sound, light) are prevented.

Controlled Breathing Exercises Group (CBE)

EXPERIMENTAL

Controlled breathing exercises will include resonant breathing, nadi shodhana, bhramari pranayama, and physiological sighing exercises. Controlled breathing exercises will be performed in a single session lasting a total of 20 minutes. Individuals will be provided with an environment where disturbing factors (sound, light) are prevented.

Other: Controlled Breathing Exercises Group

Music-Assisted Breathing Group (MAB)

EXPERIMENTAL

The music-assisted breathing exercise will perform the same breathing exercises (resonant breathing, nadi shodhana, bhramari pranayama, and physiological sighing) along with music. Individuals will be provided with an environment where disturbing factors (sound, light) are prevented.

Other: Music-Assisted Breathing Group

Interventions

Controlled breathing exercises include Resonance Breathing Exercises, Nadi Shodhana Pranayama, Bhramari Pranayama, and physiological sighing exercises. The controlled breathing exercise group will receive these exercises in a single 20-minute session. Resonance breathing will be practiced for 5 minutes at a rate of 6 breaths per minute. During the intervention, patients will receive 2 sets of Nadi Shodhana Pranayama consisting of 8 breathing cycles, with a 2-minute rest period between sets. The session will also include 2 sets of Bhramari Pranayama consisting of 8 breathing cycles at a low breathing rate, with a 1-minute rest period between sets. The physiological sighing exercise involves an initial inhalation phase lasting 1 second, a second inhalation phase lasting 0.25 seconds, and an exhalation phase lasting 2 seconds, and is repeated for 5 minutes.

Controlled Breathing Exercises Group (CBE)

The music-assisted breathing exercise will perform the same breathing exercises (resonant breathing, nadi shodhana, bhramari pranayama, and physiological sighing) along with music. Music-assisted breathing exercise will be performed in a single session lasting a total of 20 minutes. Music 1 (250-1000 Hz) and Music 2 (1000-16000 Hz) will be used at specific frequencies. A slow, rhythmically consistent, vocalless basic melody will be selected within these frequency ranges. The volume levels of all tracks will be kept constant. The music will be played through stereo headphones. Participants will listen to Music 1 (250-1000 Hz) for 10 minutes and Music 2 (1000-16000 Hz) for another 10 minutes. Individuals will be provided with an environment where disturbing factors (sound, light) are prevented.

Masking Details
The individuals to be included in the study will be randomized into three groups as Control Group (CG), Controlled Breathing Exercises Group (CBE), or Music-Assisted Breathing Group (MAB) after the first evaluations are completed. Randomization will be done with the www.randomizer.com site. The groups of individuals determined according to the order of participation will be placed in opaque envelopes and the envelopes will be closed. On the same day, the physiotherapist, who will apply the intervention will do the application according to the group that comes out of the envelope. Post-intervention assessments for all participants will be conducted by the first physiotherapist, who will remain blinded to group assignments throughout the study.

Intervention Model
PARALLEL
Model Details: The study will include individuals aged 18-40 who have moderate anxiety according to the State-Trait Anxiety Inventory and meet the inclusion criteria. Participants meeting the inclusion criteria (n=30) and completing the assessments will be randomized using www.randomizer.com into three groups: Control Group (CG) (n=10), Controlled Breathing Exercises Group (CBE) (n=10), and Music-Assisted Breathing Group (MAB) (n=10). All participants' demographic characteristics (age, gender, occupation, etc.) will be recorded using a demographic information form. The CG will receive no intervention. The CBE will perform controlled breathing exercises. The MAB will perform the same breathing exercises along with music. All assessments will be conducted before and after the exercises, and the data obtained will be recorded. All participant assessments will be conducted at the Manual Therapy Laboratory of Istanbul Health and Technology University.
