| Objective: To explore the echocardiographic characteristics of the cardiovascular structure and function of elite female boxers, and to provide a reference for the selection of female boxing talents. Subjects and methods: Echocardiography was used to study the cardiovascular structure and function of 22 female boxers and 15 ordinary female college students. Results: The heart rate and the systolic and diastolic blood pressure of the female boxers are lower than the control group (P<0.05). The LVIDd, LVIDs, LVPWd, LVIDd/BSA, LVIDs/BSA, LVM, LVMI, EDV, ESV, SV, CO and CI of the boxers are significantly higher than the control group (P<0.05), but the EF and FS are significantly lower than the control group (P<0.05). In addition, compared with the ordinary female, the cross-sectional area of carotid artery, brachial artery, radial artery, femoral artery and the inner diameter of brachial artery, femoral artery in the boxing group are all significantly larger than the control group (P<0.05). The IMT of femoral artery of the boxers is higher than that of the control group (P<0.05). The FMD of boxers is also significantly better than that of control group (P<0.05). Conclusion: The cardiovascular structure and function of elite female boxers have undergone adaptive changes after long-term training, featuring enlarged ventricular cavity, increased ventricular capacity, expanded arterial lumen area and inner diameter, and improved vascular endothelial diastolic function. |
