Abstract
Introduction: Cardiopulmonary exercise testing (CPX) systems allow for the analysis ofexercise integrative physiology involving the pulmonary, cardiovascular, muscular, and
cellular oxidative systems. Subsequently, exercise tolerance is determined by pulmonary
gas exchange; cardiovascular performance, including the peripheral vascular tree; and
skeletal muscle metabolism.Thus, present study was commenced to
evaluateimprovement in exercise tolerance after lifestyle modification using
Cardiorespiratory Exercise Testing.
Materials and Methods: This study was conducted at a Cardiopulmonary exercise
testing unit of Grant Government Medical College & Sir J.J Group of Hospitals
(Mumbai) among 50 subjects. The subjects were told to follow a lifestyle modification
which included any form of physical activity preferably brisk walking for a duration of
30 minutes at least 5 times a week for 3 months. The paired t test was used to study the
exercise tolerance of subjects after 3 months.
Results: The VO2max, AT and METS were significantly higher in non-sedentary
subjects compared to sedentary subjects. There was significant improvement in
VO2max, AT and METS after exercise.The average VO2max after exercise was 48.38
ml/kg/min, i.e. there was 11.3 % improvement in VO2 max post exercise which was very
highly significant. The average METS after exercise was 13.81, i.e. there was 11.1%
improvement in METS post exercise which was significant. The average AT after
exercise was 67.04% of VO2max, i.e., there was 10.33 % improvement in AT post
exercise which was significant.
