The International Olympic Committee (IOC) lavished praise on the progress Beijing had made in the first year after the Chinese capital was awarded the 2008 Olympic Games.The IOC s Coordination Commission had its first full meeting with the Beijing Organizing Committee (BOCOG) on December 2-4, 2002, listening to BOCOG's progress report on construction, sport, Olympic Village and services, environment, communication, marketing, accommodation and technology. The Coordination Commission also visited the city's light railway, the fourth- and fifth-ring roads, and the Olympic Green.  相似文献

Diabetes,mainly type 2 diabetes(T2D),is a major cause of blindness,kidney failure,heart attack,stroke,and lower limb amputation.Worldwide,the number of people with diabetes rose from 108 million in 1980 to 422 million in 2014 and further to 537 million in 2021,and the prevalence has been rising more rapidly in low-and middle-income countries according to a report by the World Health Organization1 and the latest data from the International Diabetes Federation.2 The positive role of physical activity(PA)and exercise as a prevention and treatment medicine for T2D has been well documented,and both the American College of Sports Medicine(ACSM)and the American Diabetes Association(ADA)have issued position statements on the effects of PA and exercise on diabetes.  相似文献

In order to examine the relationship of the athletes' impulsiveness,anger expression and the sportspersonship,368 athletes （male=256,female=102）were investigated to completed the questionnaire. The results suggested that there had a significant positive correlation between the athletes' impulsiveness and sportspersonship,there was significant difference on the sportspersonship between different impulsiveness level ;the cognitive impulsiveness and behavioral impulsiveness have significant positive prediction on the athletes' sportspersonship. There had significant relationship between the athletes' anger and the sportspersonship,there are significant sportspersonship difference between different anger level;the trait anger,state anger and anger out expression had significant prediction on the athletes' sportspersonship.  相似文献

1 The inaugural Olympic Cultural Festival opened on Sept. 21 at the Millennium Monument, where 2,008 children used red scarves and paintings to form a huge 2008 Olympic emblem. The festival, which lasted through Sept. 30, featured exhibitions of the Olympic emblems and posters and a series of mass activities in the Chinese capital city.  相似文献

Using the biomechanical simulation method based on OpenSim software which combines motion capture and muscle-bone model techniques ,this study built a lower extremity model. The dynamic optimization method was adopted to calculate the muscle force and biomechanical analysis was also used on Achilles tendon（AT）loading and muscle-tendon unit（MTU）strain. The results indicated that soleus MTU and Gastrocnemius MTU were tensile and had deformation during hurdling and running. Soleus MTU deformation difference were 0.031 mm and 0.016 mm ;Gastrocnemius MTU deformation difference were 0.031 mm and 0.031 mm;Achilles tendon loading in hurdling and running were （ 4 066.91±322.56）N and （3 361.76±194.01 ）N. This study can provide a scientific basis for the prevention of Achilles tendon injury in hurdling and further the study on Achilles tendon injury mechanism.  相似文献

Purpose:The purpose of this study was to compare knee biomechanics of the replaced limb to the non-replaced limb of total knee replacement(TKR)patients and healthy controls during walking on level ground and on decline surfaces of 5°,10°,and 15°.Methods:Twenty-five TKR patients and 10 healthy controls performed 5 walking trials on different decline slopes on a force platform and an instrumented ramp system.Two analyses of variance,2×2(limb×group)and 2×4(limb×decline slope),were used to examine selected biomechanics variables.Results:The replaced limb of TKR patients had lower peak loading-response and push-off knee extension moment than the non-replaced and the matched limb of healthy controls.No differences were found in loading-response and push-off knee internal abduction moments among replaced,non-replaced,and matched limb of healthy controls.The knee flexion range of motion,peak loading-response vertical ground reaction force,and peak knee extension moment increased across all slope comparisons between 0°and 15°in both the replaced and non-replaced limb of TKR patients.Conclusion:Downhill walking may not be appropriate to include in early stage rehabilitation exercise protocols for TKR patients.  相似文献

Background:Accumulating evidence suggests that sports participation promotes the development of inhibitory control,but the influences of the sports category and inhibition type still remain unclear.The categorization of sports based on the open-skill(externally paced)and closed-skill(self-paced)continuum allows for the integration of the environment as a factor contributing to sports-related benefits for inhibitory control.Methods:Cross-sectional data from different studies were combined(n=184)to examine the association between open-and closed-skill sports and cognitive control processes related to interference control and response inhibition.Participants(aged 9-14 years)filled in 7-day physical activity recall protocols and completed a Stroop Color-Word or a Go/NoGo task.The N200,N450,and P300 components of event-related potentials elicited by these tasks were recorded using electroencephalography.Results:Partial correlations supported the belief that time spent in open-skill sports was related to higher performance on inhibition trials.Additionally,path analyses revealed an association between this sports type and a greater negativity in the N200 and N450 amplitudes in both the full sample and group-level analyses.In contrast,no relation was found between sports type and P300 amplitude.Conclusion:The findings suggest that only the engagement in open-skill sports is associated with more effective conflict monitoring and higher performance on tasks demanding inhibitory control.  相似文献

Background:The purported ergogenic and health effects of probiotics have been a topic of great intrigue among researchers,practitioners,and the lay public alike.There has also been an increased research focus within the realm of sports science and exercise medicine on the athletic gut microbiota.However,compared to other ergogenic aids and dietary supplements,probiotics present unique study challenges.The objectives of this systematic scoping review were to identify and characterize study method...  相似文献

The special issue of the Journal of Teaching in Physical Education (JTPE)~1 on physical literacy (PL) has provided much needed information about measuring and assessing student learning in terms of the well-defined and yet abstract concept.Multiple authors have elaborated from diverse educational and psychometric perspectives on the development of the construct,the measurement model,and the assessment of the construct.In this attempt,many issues associated with the conception of PL were clarified and insightful information and arguments were brought forward.In this regard,the special issue has moved our understanding of the concept one step further.More importantly,it points to a possibility to actualize the teaching of the concept in physical education (PE).  相似文献

The on-going Coronavirus disease(COVID-19)outbreak in China has become the world's leading health headline and is causing major panic and public concerns.On January 30,2020,the World Health Organization(WHO)declared that the new coronavirus outbreak is a public health emergency of international concern.1 The virus has already had a direct impact on more than 10 million people in the city of Wuhan and has reached other parts of China as well,posing a health threat of unknown magnitude globally.As of February 8,2020,WHO reported 34,886 confirmed cases of COVID-19 globally,with 34,589 of them occurring in China(including 6101 severe cases and 723 deaths).A total of 288 other confirmed cases(with 1 death)have been reported in 24 countries,including Japan,Australia,Germany,and United States.2 However,these daily estimates are expected to rise even higher as reports from health authorities in China3 are gathered and near real-time updates of the Johns Hopkins virus dashboard are made 4 The outbreak has caused governments in various countries to take swift and protective measures.In China,these included putting cities on lockdown,5 implementing travel wamings/bans and cancellations,6 extending national holidays,and closing schools and postponing classes7.  相似文献
