ABSTRACT
Aim: (i) To assess and compare the cardiovascular response in two sub-maximal exercise tests. (ii) to see correlation between cardiovascular response and anthropometric variables. Method: 125 males 18-25 years underwent first three stages of the original Bruce protocol in one session and exercise according to Treadmill jogging test in another session in randomised order. Heart rate, blood pressure and ECG were recorded before, during and after taking the treadmill test. Results: During the exercise heart rate and systolic BP rose and diastolic BP fell in both the tests. Correlation analysis showed highly significant positive correlation between BMI and pre-exercise systolic BP, post-exercise heart rate and post-exercise systolic BPin both the tests. ECG showed no significant ST/Tor rhythm changes during or after the exercise. Conclusion: Heart rate and BPchanges were more in Bruce submaximal exercise test as compared to treadmill jogging test. Higher BMI was found to be correlated with higher resting systolic BP, higher post-exercise heart rate as well as higher post-exercise systolic BP.
ABSTRACT
Background: The current study was designed to evaluate cardio respiratory fitness in terms of VO2max in young healthy males and to correlate between body mass index and cardio respiratory fitness. Methods: One hundred twenty-five apparently healthy male subjects in the age group of 18 to 25 years were included in this study group. Body mass index was measured as weight in kilograms divided by height in meters square. Cardio respiratory fitness in terms of VO2max was predicted by following the protocol of Treadmill Jogging Test (TMJ). Results: There was a highly significant negative correlation between body mass index and VO2max, r = -0.75 p<0.0001. Conclusion: The result suggests that the reduced cardiac performance during progressive work rate exercise in obese individuals. Greater the BMI, more severe will be the functional impairment, suggesting excessive amount of body fat on cardio-respiratory functions and oxygen uptake by working muscles
