The report delivered by Jiang Zemin to the 16th National Congress of the Communist Party of China (CPC) has clearly put forward the objective of building a well-off society in an all-round way in China. The term "xiaokang", or "well-off society", which means a society in which all people lead a fairly comfortable life, was first used by late Chinese leader Deng Xiaoping, who was reputed as the "chief architect" of China's reform and opening up drive. What concerns this magazine most is what recreational sports are going to be in "xiaokang" society. The following sports are expected to be more popular in the future 20 years.  相似文献

Background In many sports,athletes with low body weight and/or low body fat content have a distinct advantage over their opponents.Such an advantage can easily turn into a noticeable disadvantage because low body weight and 'leanness' may also be associated with health problems.Anorexia Athletica(AA) is associated with leanness and thinness in female and male sports athletes despite the fact that these athletes are often very successful.High-competitive athletes often restrict their caloric intake and/or increase their energy expenditure to maintain a low body mass and/or a low amount of body fat.Several metabolic and endocrine disturbances are often the result of prolonged energy restriction.These disturbances can be detected by alterations in the hormonal profile(low levels of leptin,increased levels of ghrelin) and in changes in body composition.  相似文献

Background: One main purpose of the World Anti-Doping Agency was to harmonize anti-doping efforts, including the provision of anti-doping education. A multifaceted approach to doping prevention can play a key role in preventing intentional and unintentional doping. This article aimed to systematically record and evaluate doping prevention approaches in the form of information and education activities of national antidoping organizations(NADOs) and assess the extent to which a multifaceted doping prevention approach has been realized.Methods: Data on anti-doping information and education activities of 53 NADOs were collected via a survey and an online search of the NADOs' websites. Prevention activities were classified into knowledge focused, affective focused, social skills, life skills, and ethic-and valuebased.The implementation of the prevention activities was assessed by 4 independent raters using a modified visual analogue scale.Results: In total, 59% of the NADOs(n = 38) returned the survey and 70%(n = 45) had information available online. The data were combined for the visual analogue scale assessment. Overall, 58% of the NADOs(n = 37) reported offering activities including elements of all 5 approaches.Results of the raters' assessments indicated that the knowledge-focused approach was best implemented;the implementation of the other 4 approaches was largely unsatisfactory. The most common barriers to implementing doping prevention programs reported by the NADOs were lack of resources(n = 26) and difficulties in collaborating with sports organizations(n = 8).Conclusion: Results show a discrepancy between NADOs' self-report data and the implementation assessment. Even though the NADOs indicated otherwise, most of their education-based approaches did not address aspects of the visual analogue scale(e.g., resisting peer pressure) and only a few programs were ongoing. Possible explanations might be found in the reported barriers(e.g., financial). Concrete guidelines defining multifaceted, values-based education, and best practice examples should be developed to indicate how to include all 5 approaches in prevention.  相似文献

In this study,surface EMG signals from bilateral erector spine as well as kinematic variables of lumbar spine of 20 male adult subjects were recorded and analyzed synchronically during their performances of trunk flexion-extension with 7 different lift loads. The results showed that different lifting load has no effect on both inclination angle and flexion angle at the time of EMG-off or EMG-on ,and flexion relaxation phenomenon of erector spine either. With the increase of lifting load,the maximum low back moment,the low back moment at the time of EMG-off and that at the time of EMG-on be－ came significantly larger. In the load-sharing relationship,the passive tissue could not significantly get a compensation from muscular activation of erector spine,which is a highly risk situation of injury for passive tissues in low back area especially when lifting with a greater load.  相似文献

Background:Osteoarthritis is one of the leading causes of pain and disability worldwide,and a large percentage of patients with osteoarthritis are individuals who are also obese.In recent years,a series of animal models have demonstrated that obesity-inducing diets can result in synovial joint damage(both with and without the superimposition of trauma),which may be related to changes in percentage of body fat and a series of low-level systemic inflammatory mediators.Of note,there is a disparity between whether the dietary challenges commence at weaning,representing a weanling onset,or at skeletal maturity,representing an adult onset of obesity.We wished to evaluate the effect ofthe dietary exposure time and the age at which animals are exposed to a high-fat and high-sucrose(HFS) diet to determine whether these factors may result in disparate outcomes,as there is evidence suggesting that these factors result in differential metabolic disturbances.Based on dietary exposure time,we hypothesized that rats fed an HFS diet for 14 weeks from weaning(HFS Weanling) would demonstrate an increase in knee joint damage scores,whereas rats exposed to the HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult) and rats exposed to a standard chow diet(Chow)would not display an increase in knee joint damage scores.Methods:Male Sprague-Dawley rats were fed either an HFS diet for 14 weeks from weaning(HFS Weanling) or an HFS diet for 4 weeks,starting at 12 weeks of age(HFS Adult).At sacrifice,joints were scored using the modified Mankin Criteria,and serum was analyzed for a defined subset of inflammatory markers(Interleukin-6,leptin,monocyte chemoattractant protein-1,and tumor necrosis factorα).Results:When the HFS Weanling and HFS Adult groups were compared,both groups had a similar percent of body fat,although the HFS Weanling group had a significantly greater body mass than the HFS Adult group.The HFS Weanling and HFS Adult animals had a significant increase in body mass and percentage of body fat when compared to the Chow group.Although knee joint damage scores were low in all 3 groups,we found,contrary to our hypothesis,that the HFS Adult group had statistically significant greater knee joint damage scores than the Chow and HFS Weanling groups.Furthermore,we observed that the HFS Weanling group did not have significant differences in knee joint damage scores relative to the Chow group.Conclusion:These findings indicate that the HFS Weanling animals were better able to cope with the dietary challenge of an HFS diet than the HFS Adult group.Interestingly,when assessing various serum proinflammatory markers,no significant differences were detected between the HTS Adult and HFS Weanling groups.Although details regarding the mechanisms underlying an increase in knee joint damage scores in the HFS Adult group remain to be elucidated,these findings indicate that dietary exposure time maybe less important than the age at which an HFS diet is introduced.Moreover,increases in serum proinflammatory mediators do not appear to be directly linked to knee joint damage scores in the HFS Weanling group animals but may be partially responsible for the observed knee joint damage in the adults over the very short time of exposure to the HFS diet.  相似文献
