奥林匹克“五”知道

The Olympic flag has a plain white background with no border. In the centre are five rings forming two rows of three rings above and two below. The rings of the upper row are, from left to right, blue, black and red. The rings of the lower row are yellow and green.The rings are thought to symbolise the five continents; Europe, Asia, Africa, Australia and America. It is widely believed that the colours of the rings were chosen because at least one of them can be found in the flag of every nation, though this has never been confirmed as the intention of the designer.The flag was presented by Games founder Baron de Coubertin at the 1914 Olympic Congress, celebrating the 20th anniversary of the founding of the IOC. It was first flown in Alexandria, Greece, but made its Olympic debut at the 1920 Antwerp Games. This well-worn flag was finally retired after the 1984 Games, and a new one flown at the 1988 Seoul Games.

体育干预对青少年网络成瘾的影响

Explore the effects of sports intervention on adolescent internet addiction. In experiment 1,the non-specifically designed interventions effects were investigated. Using single-factor multi-baseline design,the subjects paired and randomly divided into experimental and control groups according to Internet addiction disorder. Results：sports intervention has better effect on adolescent with mild,moderate internet addiction than adolescent subjects with severe addiction intervention. In experiment 2,based on the results of experiment 1,the effects of the different types of sports interventions on different levels of internet addiction were explored. Using 3 （addiction level）×3 （sports Intervention Project）two-factor mixed design. Results showed that group sports interventions have more effect than individual projects,extent of internet addiction and type of project intervention was an interaction. For mild to moderate internet addiction,sports intervention whether groups project or individual were tested better than subjects with severe addiction. In experiment3,the effects of different types of sports intervention on the different types of Internet addiction were explored. Using 2 （addiction types）× 2（sports Intervention Project）two-factor mixed design. Results showed that group project interventions were tested better than individual interventions on non-online game addiction subjects. Sports individual items and group project intervention were tested in the gaming addiction no significant difference. On this basis ,using action research on typical subject for a detailed changes report during the intervention. The results suggest that sports intervention take a positive role on improvement of youth internet addiction disorder,the ways and means of intervention need to be further explored.     

A clash of fundamental assumptions: Can/should we measure physical literacy?

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).     

A physically active lifestyle is related to a lower level of skin autofluorescence in a large population with chronic-disease (LifeLines cohort)

Background:Physical activity(PA)has substantial health benefits and is important in combatting chronic diseases,which have been associated with elevated levels of advanced glycation endproducts(AGEs).AGEs play a role in the aging process,and an association between PA and AGEs has been reported.We aimed to investigate the relationship between PA and AGE accumulation in a general population and in a population with chronic diseases.Methods:This large cross-sectional population study used data from adult participants in the LifeLines project,with participant information drawn from the LifeLines database as well data from patients with diabetes mellitus or renal and/or cardiovascular diseases.Tissue AGE accumulation was assessed non-invasively by skin-autofluorescence(SAF)using an AGE reader(DiagnOptics Technologies BV,Groningen,the Netherlands).PA was assessed using the short questionnaire to assess health-enhancing physical activity(SQUASH).Multivariate linear regression analyses were adjusted for age,body mass index,sex,and smoking status.Results:Data from 63,452 participants(general population n=59,177,chronic disease n=4275)were analyzed.The general population was significantly younger(43.58±11.77 years,mean±SD)and had significantly lower SAF(1.90±0.42 arbitrary units(AU))compared to the population with chronic disease(age:55.51±12.07 years;SAF:2.27±0.51 AU).In the group with chronic disease,more hours of moderate to vigorous physical activities per week were associated with lower SAF(β=-0.002,95%confidence interval(95%CI):-0.002 to-0.001).For the general population,there was no association between hours of moderate to vigorous activity and SAF(β=3.2×10^-5,95%CI:0.000-0.001,p=0.742).However,there was an association in the general population between total hours of PA per week and SAF(β=4.2×10^-4,95%CI:0.000-0.001,p<0.001),but this association was not found in the chronic disease population(β=-3.2×10^-4,95%CI:-0.001 to 0.000,p=0.347).Conclusion:Our study demonstrates that an inverse relationship exists between PA and AGE accumulation in the population with chronic disease.More hours of moderate to vigorous activity is associated a significantly decreased SAF.More PA is associated a lower SAF,even after for the established predictors(age,body mass index,smoking status,and sex).Our findings could help to promote health and prolong longevity.     

Interference screws vs. suture anchors for isolated medial patellofemoral ligament femoral fixation: A systematic review

Purpose:The present study aimed to systematically review and compare 2 femoral autograft fixation techniques,namely,interference screws and suture anchors,for isolated medial patellofemoral ligament reconstruction in patients with recurrent patellofemoral instability at mid-to long-term follow-up.Methods:A literature search was performed in September 2020.All studies reporting the outcomes of primary isolated medial patellofemoral ligament reconstruction for recurrent patellofemoral instability were considered for inclusion.Only studies reporting the type of femoral autograft fixation under examination were considered.Studies reporting data from patients with elevated tibial tuberosity-tibial groove,patella alta,and/or Dejour’s trochlear dysplasia types C and D,were not included.Only articles reporting data with a minimum follow-up period of 18 months were considered.Results:Data from 19 studies(615 patients)were retrieved.The overall age was 24.4±6.7 years(mean±SD).The mean follow-up was 46.5±20.9 months.There were 76 patients in the anchor group and 539 in the screw group.Comparability was found with regard to age and follow-up duration between the 2 study groups.There was comparability between the Kujala,Lysholm,and Tegner scores at baseline.At the last follow-up,no worthy differences were found in terms of mean Kujala(+2.1%;p=0.04),Lysholm(+1.7%;p=0.05),and Tegner(+15.8%;p=0.05)scores.Although complications occurred almost exclusively in the screw cohort,no statistically significant difference was found.Conclusion:Femoral autograft fixation through interference screws or suture anchors report similar clinical scores and rate of apprehension test,persistent joint instability,re-dislocations,and revisions.These results must be interpreted within the limitations of the present study.     

Exercise-induced adaptation of neurons in the vertebrate locomotor system

Vertebrate neurons are highly dynamic cells that undergo several alterations in their functioning and physiologies in adaptation to various external stimuli.In particular,how these neurons respond to physical exercise has long been an area of active research.Studies of the vertebrate locomotor system’s adaptability suggest multiple mechanisms are involved in the regulation of neuronal activity and properties during exercise.In this brief review,we highlight recent results and insights from the f...     

Poetic Dwelling in the Repressive Urban Space——A Spatial Narratological Study of the Existential Crisis in J.D.Salinger's "The Young Folks",The Catcher in the Rye and Franny and Zooey

In the 1950s and early 1960s,the American society took on an air of unprecedented material prosperity.However,the flourishing economy failed to provide people with the spiritual content they expected to come with it.The inanition in the spiritual world and the affluence in the material world created a sharp contrast which led to a growing sense of anxiety and dissatisfaction.As a result,"many Americans reacted to these developments with ambivalence,even hostility." (Brinkley 1999:1010) It was against this milieu that Jerome David Salinger examines his growth as a young middle class American in retrospect and started his literary career.     

Muscle strength cut-offs for the detection of metabolic syndrome in a nonrepresentative sample of collegiate students from Colombia

Background: Evidence shows an association between grip strength and health;however, grip strength cut-offs for the detection of metabolic syndrome(MetS) in Latin American populations are scarce. The purpose of this study was to determine cut-offs of normalized grip strength(NGS)for the detection of MetS in a large nonrepresentative sample of a collegiate student population from Colombia.Methods: A total of 1795 volunteers(61.4% female;age = 20.68 ± 3.10 years, mean ± SD), ranging between 18 and 30 years of age participated in the study. Strength was estimated using a handheld dynamometer and normalized to body mass(handgrip strength(kg)/body mass(kg)). Anthropometrics, serum lipids indices, blood pressure, and fasting plasma glucose were measured. Body composition was measured by bioelectrical impedance analysis. MetS was defined as including ≥3 of the 5 metabolic abnormalities according to the International Diabetes Federation definition. A metabolic risk score was computed from the following components: waist circumference, triglycerides, high-density lipoprotein cholesterol, glucose, and systolic and diastolic blood pressure.Results: Receiver operating curve analysis showed significant discriminatory accuracy of NGS in identifying the thresholds and risk categories.Lower strength was associated with increased prevalence of MetS. In males, weak, intermediate, and strong NGS values at these points were<0.466, 0.466-0.615, >0.615, respectively. In females, these cut-off points were <0.332, 0.332-0.437, >0.437, respectively.Conclusion: Our sex-specific cut-offs of NGS could be incorporated into a clinical setting for identifying college students at cardiometabolic disease risk.

An evaluation of prevention initiatives by 53 national anti-doping organizations: Achievements and limitations

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.

Impaired eye tracking is associated with symptom severity but not dynamic postural control in adolescents following concussion

Purpose:The purpose of the study was to(1)examine the relationship between self-reported symptoms and concussion-related eye tracking impairments,and(2)compare gait performance between(a)adolescents with a concussion who have normal eye tracking,(b)adolescents with a concussion who have abnormal eye tracking,and(c)healthy controls.Methods:A total of 30 concussed participants(age:14.4±2.2 years,mean±SD,50%female)and 30 controls(age:14.2±2.2 years,47%female)completed eye tracking and gait assessments.The BOX score is a metric of pupillary disconjugacy,with scores<10 classified as normal and≥10 abnormal.Symptoms were collected using the Post-Concussion Symptom Scale(PCSS),and gait speed was measured with triaxial inertial measurement units.We conducted a linear regression to examine the relationship between PCSS and BOX scores and a two-way mixed effects analysis of variance to examine the effect of group(abnormal BOX,normal BOX,and healthy control)on single-and dual-task gait speed.Results:There was a significant association between total PCSS score and BOX score in the concussion group(β=0.16,p=0.004,95%confidence interval(95%CI):0.06‒0.27),but not in the control group(β=0.21,p=0.08,95%CI:
0.03 to 0.45).There were no significant associations between PCSS symptom profiles and BOX scores in the concussion or control groups.There were also no significant differences in singletask(Abnormal:1.00±0.14 m/s;Normal:1.11§0.21 m/s;Healthy:1.14±0.18 m/s;p=0.08)or dual-task(Abnormal:0.77±0.15 m/s;Normal:0.84±0.21 m/s;Healthy:0.90±0.18 m/s;p=0.16)gait speed.Conclusion:The concussed group with impaired eye tracking reported higher total symptom severity,as well as worse symptom severity across the 5 PCSS symptom domain profiles.However,eye tracking deficits did not appear to be driven by any particular symptom domain.While not statistically significant,the slower gait speeds in those with abnormal BOX scores may still be clinically relevant since gait-related impairments may persist beyond clinical recovery.
