Self-reported symptoms and risk factors for digital ischaemia among international world-class beach volleyball players

The prevalence of ischaemia-related symptoms is remarkably high among elite indoor volleyball players. Since the exposure to sport-specific demands may be higher in beach volleyball compared to indoor volleyball, the aim of this study was to assess the prevalence of ischaemia-related symptoms and associated risk factors among world-class beach volleyball players. Therefore, a questionnaire survey was performed among beach volleyball players active during the 2013 Grand Slam Beach Volleyball in the Netherlands. In total, 60 of the 128 beach volleyball players (47%) participated: 26 males and 34 females from 17 countries. The self-reported prevalence of cold or blue or pale digits in the dominant hand during or immediately after practice or competition was 38% (n = 23). Two risk factors were independently associated with symptoms of blue or pale digits: more than 14 years playing volleyball (odds ratio (OR) 4.42, 90% confidence interval (90% CI) 1.30–15.07) and sex (female) (OR 4.62, 90% CI 1.15–18.57). In conclusion, the prevalence of symptoms associated with digital ischaemia is high among international world-class beach volleyball players. Female sex and the length of the volleyball career were independently associated with an increased risk of ischaemia-related symptoms. The high prevalence of these seemingly innocuous symptoms and possible associated risk factors warrant regular monitoring since early detection can potentially prevent thromboembolic complications and irreversible tissue damage.  相似文献

A dynamic decision model for portfolio investment and assets management     

QIAN Edward Y.  FENG Ying  HIGGISION James 《浙江大学学报(A卷英文版)》2005,6(Z1)

This paper addresses a dynamic portfolio investment problem. It discusses how we can dynamically choose candidate assets, achieve the possible maximum revenue and reduce the risk to the minimum level. The paper generalizes Markowitz's portfolio selection theory and Sharpe's rule for investment decision. An analytical solution is presented to show how an institutional or individual investor can combine Markowitz's portfolio selection theory, generalized Sharpe's rule and Value-at-Risk(VaR) to find candidate assets and optimal level of position sizes for investment (dis-investment). The result shows that the generalized Markowitz's portfolio selection theory and generalized Sharpe's rule improve decision making for investment.  相似文献   

外商直接投资对我国产业集群发展的影响及对策     

李明武 《荆州师范学院学报》2007,30(3):69-73

外商直接投资对我国地方产业集群的形成和发展起到了重要的推动作用，但外资拉动型产业集群也存在外资根植性差、与本地企业关联度低、外资企业凭借技术优势压制内资企业的利益空间、集群发展缺乏稳定性和可持续性等问题。因此必须加强集群的环境建设，增强内、外资企业的配套关联度，提高外资的社会网络根植性水平，同时要积极推进本地中小企业科技进步，建立并维护集群内自律机制，改善内资企业在集群内的不利地位，避免内资企业间的恶性竞争。  相似文献
