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   

黑龙江省冰雪装备制造业创新成长影响要素与战略研究     

张良祥  连洪业  彭迪  宋智梁  马阳 《冰雪运动》2016,(4)

随着我国成功申办2022年冬奥会,我国将大力发展冰雪运动,并会随之带动旅游、经济和冰雪装备制造业的发展。而冰雪装备制造业的发展直接影响我国冰雪体育事业的开展。采用文献资料、调查、系统分析等研究方法,针对黑龙江省冰雪装备制造业的创新成长问题进行研究,并对黑龙江省的冰雪装备制造业创新成长影响要素以及企业创新成长存在的问题进行分析与总结,认为黑龙江省冰雪装备制造业创新成长的总体状况是良好的,但企业存在资金短缺,经营、管理、技术等方面人才匮乏,企业产品结构单一、产品科技创新意识和能力不强,欠缺可持续发展理念等问题。通过分析影响冰雪装备制造业创新成长的原因,提出引进与自我创新相结合、注重品牌质量、发扬政府主导优势等战略,旨为冰雪装备制造业在黑龙江省的发展提供理论依据。  相似文献

Motivational factors for youth recruitment in voluntary interventions: the case of a community sport program     

Catherine Plante  Annie Jaimes  Carole Turbide 《Sport, Education and Society》2016,21(7):1071-1090

Recruitment is known to be a challenge for intervention programs targeting youths, including sports programs. Following the popularity of the Alter-Action program of the Montreal-based organization DesÉquilibres, we wanted to understand the motivations and barriers to youths' recruitment in this voluntary sports community program. A qualitative methodology was favored. We conducted 27 semi-structured interviews (n = 27) with participants, 5 (n = 5) with the partners, and we carried out a focus group with 5 (n = 5) of the organization's service practitioners. We also conducted a participant observation with youth cohorts and during preparatory meetings. Five factors influencing recruitment emerged: (1) socialization/belonging; (2) training/physical aspects; (3) ‘extraordinary’ dimension; (4) practicality of the program; and (5) social influences. Four key elements thus appear important to consider when promoting the recruitment of youths in voluntary community programs: (1) favoring social interactions; (2) insisting on the specific and beneficial elements of the program; (3) allowing youths to experiment a trial period; and (4) including testimonies of former participants in the information session. Further recommendations for psychosocial intervention programs targeting youths are discussed in this article.  相似文献   

Effects of load mass carried in a backpack upon respiratory muscle fatigue     

Mark Faghy  Sam Blacker  Peter I. Brown 《European Journal of Sport Science》2016,16(8):1032-1038

Purpose: The purpose of this study was to investigate whether loads carried in a backpack, with a load mass ranging from 0 to 20?kg, causes respiratory muscle fatigue. Methods: Eight males performed four randomised load carriage (LC) trials comprising 60?min walking at 6.5?km?h^?1 wearing a backpack of either 0 (LC₀), 10 (LC₁₀), 15 (LC₁₅) or 20?kg (LC₂₀). Inspiratory (P_Imax) and expiratory (P_Emax) mouth pressures were assessed prior to and immediately following each trial. Pulmonary gas exchange, heart rate (HR), blood lactate and glucose concentration and perceptual responses were recorded during the first and final 60?s of each trial. Results: Group mean P_Imax and P_Emax were unchanged following 60-min load carriage in all conditions (p?>?.05). There was an increase over time in pulmonary gas exchange, HR and perceptions of effort relative to baseline measures during each trial (p?p?>?.05). Conclusions: These findings indicate that sub-maximal walking with no load or carrying 10, 15 or 20?kg in a backpack for up to 60?min does not cause respiratory muscle fatigue despite causing an increase in physiological, metabolic and perceptual parameters.  相似文献

论我国封闭式基金折价问题     

杨建海 《温州大学学报(社会科学版)》2005,18(1):42-45

封闭式基金折价是困扰众多投资和研究的问题，先前有很多研究从不同的角度来探讨原因。本在分析了规模相近的基金折价率变动相关性的基础上，选择了两个可能与折价率变动有关联的变量进行回归分析，结果表明：基金折价率的变动与市场因素不相关，而非市场因素一投资情绪对折价率产生主要影响。  相似文献
