Changes in Lung Function Measures Following (Bellows Breath) and Running in Healthy Individuals.

BACKGROUND

The purpose of this study was to observe the effect of (bellows breath) and exercise on lung function of healthy individuals.

MATERIALS AND METHODS

A total of thirty male participants were recruited and randomly divided into two groups, i.e., yoga breathing group (YBG, = 15) and physical exercise group (PEG, = 15), and the participants' ages ranged between 18 and 30 years (group age mean ± standard deviation, 22.5 ± 1.9 years). YBG practiced for 15 min, whereas PEG practiced running for 15 min, 6 days in a week, over a period of 1 month. The participants were assessed for (i) forced vital capacity (FVC), (ii) forced expiratory volume in the first second (FEV1), (iii) peak expiratory flow rate (PEFR), and (iv) maximum voluntary ventilation (MVV) functions of lungs.

RESULTS

Repeated-measures analyses of variance with Bonferroni adjustment analyses of multiple comparisons showed that there was a significant increase in YBG for all variables, i.e., FVC, FEV1, PEFR, and MVV ( < 0.001, < 0.001, < 0.01, and < 0.001, respectively), whereas there was a significant increase in PEFR and MVV ( < 0.05 and < 0.01, respectively) only, among PEG. However, the change in PEG was less of magnitude as compared to YBG.

CONCLUSIONS

These findings demonstrate that incorporating in sports can enhance the efficiency of healthy individuals and athletes by enhancing the ventilatory functions of lungs, especially for those who partake in aerobic-based sports and require efficient lungs to deliver sufficient oxygen uptake.
