Background Young individuals are often at a higher risk for cardiovascular disease and obesity due to lifestyle changes like less physical activity and a sedentary lifestyle. Objective The aim of this study is to determine cardiovascular fitness in young individuals and to study the effects of obesity on their cardiovascular fitness. Material and methods In this study, 100 young individuals, out of which 50 were individuals with obesity and 50 were controls, including males and females, of the age group 18-25 years were included. Cardiovascular fitness was assessed in them using body mass index (BMI) and waist-to-hip ratio (WHR). Parameters like SBP (systolic blood pressure), DBP (diastolic blood pressure), PR (pulse rate), and HFI (Harvard fitness index) were measured. Results There was no difference found in the PR of the group with obesity compared to the control group (79.020/min ± 8.651 versus 79.42/min ± 6.737; p value = 0.797). However, a significant increase was observed in both SBP and DBP amongst the group with obesity compared to the control group (SBP = 122.72 mmHg ± 12.287 versus 110.92 mmHg ± 11.803; p-value < 0.001, DBP = 81.96 mmHg ± 7.913 versus 73.24 mmHg ± 11.06; p-value < 0.001). There was a significant reduction in HFI in the group with obesity than in the control group (57.44% ± 9.322 versus 80.34% ± 12.594; p-value < 0.001). When we compared males with obesity and females with obesity, we observed a non-significant difference in PR between males with obesity and females with obesity (77.12/min ± 6.02 versus 80.92/min ± 10.44; p-value = 0.122). However, we found a significant increase in SBP in males with obesity compared to females with obesity (127.76 mmHg ± 10.93 versus 117.68 mmHg ± 11.66; p-value < 0.01). A significant decrease in DBP in males with obesity (78.80 mmHg ± 7.55 versus 85.12 mmHg ± 7.07; < 0.01) than in females with obesity was also observed. Along with a non-significant increase in HFI value in males with obesity compared to females with obesity (58.96% ± 8.14 versus 55.92% ± 10.31; p-value = 0.253). Conclusion Results suggest that both male and female young individuals with obesity are at higher risk for developing cardiovascular comorbidities in the future. So, we need to focus on encouraging activities that promote physical fitness.
