Abstract
The aim of this study was to investigate the relationship between cardiopulmonary fitness as indicated by 5minutes (5min.) work rate (W5min.) production, body mass index (BMI), systolic blood pressure and heart rate reserve. A total of 144 sedentary volunteers (78 males, 66 females), aged 18-22 years were enrolled in the study. For male group the average BMI was 27.67+/-0.517 kg/m2 (range between 17.7 and 46.4) with standard deviation 4.567, while in female group the average BMI was 29.71+/-0.677 kg/m2 (between 16.9 and 44.4) with standard deviation 5.498. Each subject performed an exercise test (15 W/min) for five minutes on an electromagnetically-braked cycle ergometer. Heart rate at rest multiplied by systolic blood pressure (SBP) at rest formed the base line figures compared to the output figures found by multiplying SBP by the peak heart rate taken at the end of exercise. Correlation between base line and output figures for all the group was significant (r=0.32) and also for the female group(r=525) but insignificant for the male group (r0.213). BMI was negatively correlated with baseline figures in both groups. The results of the present study have suggested that, due to the inverse correlation between BMI, W5min. and heart rate reserve, it may be useful to consider BMI in establishing cardiopulmonary fitness in various subjects.
