In the experimental group, the LF:HF ratio decreased by 34.12% (p=0.007), HFnu increased by 25.69% (p=0.024), and LFnu decreased by 23.05% (p=0.024), with no significant changes observed in the control group.

Why the study?

Heart rate variability provides information on autonomic balance, but the chronic effects of slow and controlled breathing exercises in physically active, healthy adults needed evaluation.

Does slow, controlled breathing exercise improve heart rate variability in physically active, healthy individuals?

Population

22 physically active, healthy individuals (11 female, 11 male)

Comparison

Slow, controlled breathing exercises vs control

Design

Controlled trial

Overview

Slow breathing may boost parasympathetic tone in active adults; leaves open clinical outcome benefits and requires RCTs.

Structured PICO

Does slow, controlled breathing exercise improve heart rate variability in physically active, healthy individuals?

Population

22 physically active, healthy adults (11 female, 11 male). Excluded: individuals with lower level of physical activity (<150 min/week of 3-6 MET), athletes, individuals having any diseases, and people who had respiratory problems up to six months before the study.

Intervention

Slow and controlled breathing exercises (10 sec diaphragmatic breathing cycles: 5 sec inhale, 5 sec exhale, 6 breaths/min) for 15 minutes per day, 3 days a week for 6 weeks.

Comparator

Control group receiving no breathing exercises and not joining any regular physical activity program during the study.

Outcome

Heart rate variability (HRV) parameters (SDNN, SDSD, RMSSD, TP, LF:HF ratio, HF, HFnu, LF, LFnu, and VLF) measured before and after the six-week process.surrogate

Six weeks of slow, controlled breathing exercises significantly improved parasympathetic activity markers of heart rate variability in physically active, healthy adults.

Limitations

Duration of the study (six weeks) may need to be longer to observe significant changes in time-domain parameters
