The results show that the Failure Anxiety of China＇s young women＇s volleyball athletes is less than that of the norm, while the other kinds of anxiety are more. The athletes whose sports time is more than seven years have a higher level of Injury Anxiety, so is the anxiety when preparing for matches of Three Stage Athletes than One Stage Athletes and Two Stage Athletes. In comparison with Level Two Stage Athletes and Level Three Stage Athletes, Level One Stage Athletes＇ ability anxiety is higher. The anxiety of fonts＇ playing competitive level is more than setters. Based on different athletes, we should take different measures, in order to improve their psychological resilence through training and increase their tolerance when facing difficulty through matches.展开更多

Previous studies have suggested the association between central arterial stiffness and the degree of GFR loss. Whether decreased GFR contributes to peripheral artery stiffness remains controversial. Moreover, data analyzed from a cohort of Chinese women are rare. Our aim was to explore the relationship between GFR and regional arterial stiffness in Chinese women. Methods In this cross-sectional study, we randomly recruited 1131 adult women residents with GFR 〉 60 mL/min per 1.73 m2 estimated by the Chinese Modification of Diet in Renal Disease equation from three large communities. Central and peripheral arterial stiffness were estimated simultaneously by measuring carotid-femoral pulse wave velocity （PWVcf） and carotid-radial PWV （PWVcr） using a validated automatic device. Augmentation Index at heart rate 75 beats/minutes （AIx-75） was measured by pulse wave analysis as a composite parameter reflecting both large and distal arterial properties. Results The mean estimated GFR （eGFR） of the study group was 100.05 ＋ 23.26 mL/minute per 1.73 m2. Subjects were grouped by tertiles of eGFR level. PWVef and AIx-75 increased ongoing from the top to the bottom eGFR tertile, while the values of PWVcr were comparable. Both univariate Pearson correlations and multiple stepwise regression analyses showed that eGFR significantly correlated to PWVcf, but not to PWVcr and AJx-75. Conclusions In Chinese women with normal to mildly impaired renal function, decreased eGFR affected carotid-to-femoral rather than carotid-to-radial stiffening. This provides rational to conduct future prospective studies to investigate predictors of atherosclerosis in this population.展开更多
