AbstractBasketball incorporates intense eccentric muscle activity that induces muscle microtrauma and an inflammatory response. This study investigated time-dependent inflammatory and performance responses during a weekly microcycle after a basketball match. Twenty elite-standard players underwent a trial that comprised a match followed by a 6-day simulated in-season microcycle. The trial was preceded by a control condition that did not have a match. Blood sampling and tests of maximal-intensity exercise performance and muscle damage occurred before each condition, immediately after the match and daily thereafter for 6 consecutive days. The match induced marked increases in heart rate, lactate, ammonia, glucose, non-esterified fatty acids and triglycerides. Performance deteriorated for 24–48 h after the match, whereas knee flexor and extensor soreness increased for 48 and 24 h post-match, respectively. Inflammatory (leukocytes, C-reactive protein, creatine kinase activity, adhesion molecules, cortisol, uric acid and cytokines) and oxidative stress (malondialdehyde, protein carbonyls, oxidised glutathione, antioxidant capacity, catalase and glutathione peroxidase) markers increased for ~24 h and subsided thereafter. Reduced glutathione declined for 24 h after exercise. These results suggest that a basketball match elicits moderate and relatively brief (~24–48 h) inflammatory responses, is associated with marked but short-lived performance deterioration, but is less stressful than other intermittent-type sports. 相似文献

理论运用实践是体育科学的主要目的。体育科研人员必须将其研究信息成果,及时传递蛤教练及运动员,使他们在实践中加以应用。本研究针对1999年在法国举行的欧洲篮球冠军赛,通过对20场比赛的录像解析,力图分析不同进攻阶段对进攻产生的影响。所有数据的统计及处理,均利用一计算机篮球软件(BasketballAnalysisSystem)来处理。研究结果表明,在不同的进攻阶段内,进攻次数、投篮命中率、助攻等方面存在着差异。 相似文献

希腊职业篮球俱乐部组织比赛前的季前训练,无论是国家队还是俱乐队都多次在欧洲比赛中取得优异成绩。季前训练包括基础训练、提高运动员的身体素质和比赛的必胜心。通过跟踪训练和巡回参赛,运动员的个人素质和球队的整体素质都得到进一步提高。文章探讨了参加季前训练、教练员为提高运动状态、运动员个体素质和整体素质所采取的措施,指出季前训练的重要性和效果。 相似文献
