Subjects rested for 15 minutes before
measurements and were informed about the
procedure. After appropriate placement of
mouthpiece and nose clip, each subject was asked to
do a forced quick expiration after maximum
inhalation. After doing at least three acceptable and
repeatable FVC maneuvers, the largest FVC, MVV
and FEV1 were recorded after examining the data
from all of these attempts (19). FVC, FEV1, MVV,
height, weight and BMI were measured pre, mid (12th
week) and post (24th week) exercise in both groups.
Measurement of FEV1 reflects conductive / resistive
properties of the large airways (20), FVC is related to
the contractility of the expiratory muscles and MVV
is correlated with the respiratory muscle performance
(20). All the volumes were reported in BTPS (Body
Temperature and Pressure Saturated (21). ECCS set
of equations were used by Spirolab III to calculate
the predicted / reference values according to the ERS
guidelines (21).
