Effect of forced breathing on ventilatory functions of the lung

J Postgrad Med. 1998 Jul-Sep;44(3):67-9.


Ventilatory functions were studied in 36 male and 35 female subjects (mean age 18.5 years), who underwent six weeks course in forced breathing. Ventilatory functions were studied in the form of Forced Vital Capacity (FVC), Forced Expiratory Volume at the end of one second as % of FVC (FEV1%), Maximum Voluntary Ventilation (MVV), Peak expiratory flow rate (PEFR) and Breath Holding Time. Some of these ventilatory functions were found to be increased after a course of forced breathing.
