Summary

The goal of this clinical trial is to learn if diaphragmatic breathing and box breathing work to enhance resilience and manage stress in physical therapy students. It will also learn about their effects on overall physiological and psychological parameters. The main questions it aims to answer are:

Do these breathing techniques improve heart rate variability (HRV)?

How do these interventions affect participants' perceived stress levels, cognitive performance, and academic achievement?

Researchers will compare diaphragmatic breathing and box breathing to a control group to see if these non-invasive methods work to improve physiological adaptation and manage stress.

Participants will:

Be randomly assigned to practice diaphragmatic breathing, practice box breathing, or join a control group Have their heart rate variability (HRV) measured as a primary sign of physiological adaptation Complete assessments to evaluate their perceived stress, cognitive performance, and academic achievement

Conditions

  • Stress
  • Psychological Resilience
  • Healthy Students

Interventions

BEHAVIORAL

Diaphramatic Breathing Training

Diaphragmatic Breathing Group: Participants will sit comfortably with their hands in their abdomen. They will: * Inhale through the nose for 4 seconds * Exhale through the mouth for 6 seconds * Focus on abdominal expansion and relaxation * Continue for 15 minutes, 6 sessions/week, for 4 weeks

BEHAVIORAL

Box Breathing Training

Box Breathing Group: Participants will perform a structured breath cycle: * Inhale for 4 seconds * Hold for 4 seconds * Exhale for 4 seconds * Hold for 4 seconds
