For Purpose 1,the players(n = 17) and the untrained(n = 24) boys were tested for speed, jumping power, postural balance, flexibility, and aerobic capacity. After baseline testing, Purposes 2 and 3 were addressed by randomly assigning the untrained boys to either a soccer-training group(small-sided games,2 sessions per week for 8 weeks) or to a control group, followed by identical retesting.Results: At baseline, physical fitness was higher(p < 0.001) in trained players than in untrained for aerobic fitness, sprinting, jumping power, and postural balance. Small-sided games using 6 v 6 or 4 v 4 elicited similar heart rate(HR)(mean: ~ 85% peak heart rate, HR_(peak)), rate of perceived exertion, and enjoyment responses. Over 8 weeks, the between-group analysis revealed that soccer training had a large beneficial effect on postural balance(45%) when compared with control group with unclear effects on other fitness parameters.Conclusion: Adolescent soccer players had markedly higher physical fitness compared with untrained adolescents. Small-sided soccer games practiced by untrained adolescents elicited high exercise intensity. While 8 weeks of twice-weekly soccer training sessions induced significant improvement in postural balance, the short duration of the study was not sufficient to result in between-group differences in sprint and jump performance or aerobic fitness.展开更多

Methods： 28 patients aged over 65 with advanced NSCLC were received with docetaxel （Aisu） 35 mg/m^2 on days 1, 8 and 15 every 28 days. A clinical evaluation on effectiveness, quality of life and toxicities was performed. Results： 28 patients were given 86 cycles＇ chemotherapy altogether. The overall response rate was 35.7% （10/28）. The clinical beneficial rate was 64.3% （18/28）. Mean KPS was increased from 75.5 at baseline to 87.7 after chemotherapy （P 〈 0.01）; lung cancer symptom scale （LCSS） scores of cough, hemoptysis, chest pain and dyspnea were increased from 64, 65, 62 and 65 to 90, 92, 87 and 88, respectively （P 〈 0.01）. The median time to progression （TTP） was 5.3 months; median survival time （MST） was 8.5 months. The main toxicities were fatigue, leukopenia and decrease of hemoglobin with well tolerance. Conclusion： Weekly dose docetaxel monotherapy schedule is a feasible, well-tolerated, and active scheme in the treatment of the elderly patients with advanced NSCLC.展开更多

This echoes Reaser＇s （2003） and Ryan＇s （1993） perceptions of sports announcer＇s talk as a complex performance form based on but not limited to the ＂verbal imitation＂ of live sport events. We have understood the performativity of the LRSCs in the light of Schechner＇s （2006） emphasis of what he termed ＂restored behaviour＂ in understanding performance. In our context, we have treated the interpenetration of Kenyan soccer, politics, and society as the ＂restored behaviour＂ upon which the script of the LRSCs are based. The methodological apparatus of this paper is largely qualitative, consisting in the critical analysis of audio-recordings of Kenyan LRSCs. Focus is made on the Kenyan society of the 1980s, an era perceived to have been characterized by a close interaction between soccer, society, and politics. The analysis is informed by Fabian＇s （1997） inter-textual approach to the ＂reading＂ and interpretation of performance texts. This approach seems to echo a wider discourse of the social nature of media-text interpretation that has been proposed by Burn and Parker （1985）. Conclusions drawn from the analysis reveal what Muponde and Zegeye （2011） had described as a soccer ＂ecosystem＂ involving soccer as a sport, and the socio-cultural realities of its immediate context. This paper has argued thatLRSC is one of the channels through which this ecosystem is expressed.展开更多

Its existence in youth sports like soccer is well established. Why it occurs has not been identified, however, one thought is that older players, generally taller and heavier, are thought to improve the team＇s chances of winning. To test this assumption, birth dates and match outcome were correlated to see if teams with the oldest mean age had a systematic advantage against teams with younger mean ages. Methods： Player birth dates and team records （n = 5943 players on 371 teams; both genders; U11-U16） were obtained from the North Carolina Youth Soccer Association for the highest level of statewide youth competition. Results： The presence of an RAE was demonstrated with significant oversampling from players born in the I st vs. the 4th quarter （overall： 29.6% vs. 20.9% respectively, p 〈 0.0001）. Mean team age was regressed on match outcomes （winning %, points/match, points/goal, and goals for, against, and goal difference）, but there was no evidence of any systematic influence of mean team age and match outcomes, except possibly in U11 males. Conclusion： Selecting players based on physical maturity （and subsequently, on age） does not appear to have any systematic influence on match outcome or season record in youth soccer suggesting that the selection process should be focused on player ability and not on physical maturation.展开更多

Major international sporting events are the key channels for the exchange and dissemination of information among athletes from various countries, media coverages, national and international audiences which involves interpersonal communication, organizational communication, and mass communication at all levels. At the same time, the volunteers, especially young volunteers （mostly college student volunteers） considered as the Beijing city spokesperson and also as a group of ＂public diplomacy ambassadors＂, transfer positive energy in international communication during major international sporting events. Therefore, major international sporting events held in Beijing play an irreplaceable role in the image building of the capital city of China, Beijing.展开更多
