Effect Of Pranayama On Peak Expiratory Flow Rate & Forced Vital Capacity Among Middle Aged Females

SJSusanta Jana

Key Result

An 18-week Pranayama training program significantly increased Peak Expiratory Flow Rate by a mean difference of 0.45 L (p=0.00) from baseline in young adult females.

Key Points

  • This study aims to investigate how Pranayama affects lung function, specifically PEFR and FVC, in middle-aged females.
  • Divided female volunteers into two age groups: Young Adult (30-45 years) and Elderly Adult (46-60 years).
  • Conducted an 18-week Pranayama training program for the experimental group.
  • Measured Peak Expiratory Flow Rate (PEFR) and Forced Vital Capacity (FVC) before and after the training.
  • Used t-test for statistical analysis of the data.
  • Significant improvement in PEFR among both age groups after the training program.
  • Significant improvement in FVC among both age groups post-training.

Structured PICO

Does an 18-week Pranayama training program improve Peak Expiratory Flow Rate and Forced Vital Capacity in middle-aged females?

P
Population
54 healthy middle-aged female school staff, aged 30 to 60 years, participated in an 18-week controlled trial evaluating the effects of Pranayama on respiratory function.
I
Intervention
Pranayama training program (Vastrika, Anuloma-Viloma, Bhramari and Bahya) 5 days a week, 45-60 minutes/day for 18 weeks.
C
Comparator
No training program (control group).
O
Outcome
Peak Expiratory Flow Rate (PEFR) and Forced Vital Capacity (FVC) measured before and after the 18-week training program.surrogate

An 18-week Pranayama training program significantly improves lung function parameters (PEFR and FVC) in middle-aged females.

Main Result

Mean Difference: 0.45

Absolute Event Rate: 2.51% vs 1.97%

p-value: p=0.00

Limitations

  • Small sample size
  • Lack of true randomization between groups (participants were drawn from different schools)

Abstract

The purpose of the study was to investigate the effects of Pranayama on Peak Expiratory Flow Rate (PEFR) and Forced Vital Capacity (FVC) among middle aged female (Age ranging 30 to 60 years). There was an Experimental Group and a Control Group. According to age the subjects were divided into two groups i.e., Young Adult (YA) age ranging from 30 to 45 years and Elderly Adult (EA) age ranging from 46 to 60 years. In the present study, all the subjects (34 volunteered Female) of the Experimental groups were brought under a Pranayama training programme for 18 weeks. All the parameters i.e. Peak Expiratory Flow Rate (PEFR) and Forced Vital Capacity (FVC) were measured before and after the Training Programme. For statistical analysis and interpretation of data ‘t-test was conducted. Result showed a significant change in PEFR and FVC among both YA and EA of the experimental subjects.

Susanta Jana (2025) studied Healthy (n=54). Pranayama vs. No training was evaluated on Peak Expiratory Flow Rate (PEFR) in Young Adults (30-45 years) (MD 0.45, p=0.00). An 18-week Pranayama training program significantly increased Peak Expiratory Flow Rate by a mean difference of 0.45 L (p=0.00) from baseline in young adult females.
