This research was designed to evaluate the effect of cardiovascular exercises on body mass index (BMI) and vital capacity (VC) among student aged between 21-27 years (M ± SD 22.3± 3.05). The experimental research study was applied to 54 University students of Sargodha. Data were analyzed by using SPSS version 24.0. P-value ? 0.05 was considered significant. The result showed that the average BMI of the control group and experimental groups was 20.73±3.02 vs 21.51±3.21. The effectiveness of cardiovascular exercise on Vital capacity on Pre and post-test of the experimental group was -56.91272 ± 22.03192 with a pvalue of 0.000, which was showed there was a highly significant improvement in vital capacity of students and compare with the control group. It was concluded that body masses index and vital capacity is significantly improved in university students of the experimental group as a result of 10 weeks of the cardiovascular exercise training program. Conclude that there is a significant difference between the effects of cardiovascular exercise and daily routine sports activities on BMI.
