College students in experiment groups exercised 3-5 times a week, 90min each time, at a medium exercise intensity (their heart rates were controlled within 120-150 beats/min). Results: As for students in experiment groups, after experi-ment, their HR, SV and HOI values of decreased significantly, and the differences were very significant (P<0.01), their CO, SI and CI values of increased significantly, and the differences were significant (P<0.05), their PP and MAP values decreased slightly, and the differences were not significant (P>0.05), their MSP, MDP and MAP values decreased significantly, and the differences were significant (P<0.05), their TR values decreased significantly, and the differences were very significant (P<0.01), their AC values increased significantly, and the differences were sig-nificant (P<0.05), their VB and OV value had no significant change, and the differences were not significant (P>0.05), their V values decreased significantly, and the differences were significant (P<0.05), their ALK values in-creased significantly, and the differences were significant (P<0.05), their ALT and TM values decreased signifi-cantly, and the differences were very significant (P<0.01). The results indicated that the 18-week flow yoga exercise and ball yoga exercise can effectively improve cardiovascular functions of college students, and the roles of ball yoga in improving cardiovascular functions of college students are better than those of flow yoga.
