Abstract
Body Mass Index and Peak Expiratory Flow Rate are important measures of
body composition and lung function. Physical exercise has been shown to
influence both parameters; however, the relationship between the two among
physiotherapy students is unknown. The purpose of this correlational study was
to establish the relationship between Body Mass Index and Peak Expiratory Flow
Rate among undergraduate physiotherapy students, as well as to compare Peak
Expiratory Flow Rate values between exercising and non-exercising individuals,
which were defined using the International Physical Activity Questionnaire. 150
subjects were evaluated for Body Mass Index (weight/height²) and Peak
Expiratory Flow Rate (peak flow meter). The data were evaluated with Spearman
correlation and Mann-Whitney U tests. The results showed that there was no
statistically significant link between Body Mass Index and Peak Expiratory Flow
Rate (p > 0.05), and there were no significant differences between the
exercising and non-exercising groups. These findings indicate that Body Mass
Index alone may not predict pulmonary function in physiotherapy students.
Factors like respiratory muscle strength and general fitness could have a
bigger impact.
