A study on cardiovascular fitness of male medical students

Background Cardiovascular fitness has been found to be significantly compromised by obesity, whose prevalence is increasing rapidly. The present study aimed to assess the aerobic exercise performance in terms of maximum aerobic power (VO2 max) of the male students of North Bengal medical college in the age range of 18-22 years.

Methods The subjects were divided into two groups viz. control (N=52) and study (N=43) on the basis of Body Mass Index (BMI) and Waist Circumference (WC), according to the current Indian guidelines for obesity. The VO2 max was compared among the two groups. It was evaluated using the Bruce protocol, and also expressed in terms of ‘Metabolic equivalents’ (MET).

Results VO2 max exhibited significant negative correlation with BMI (r=0.75, P <0.000) and WC (r=0.72, P <0.000). VO2 max was higher for the normal group compared to the study group, and the mean difference was significantly different [P <0.05(0.000)].

Conclusion The study thus showed that cardiovascular capacity is compromised by excess adiposity.
