to be or not to be

时间：６月２５日　０２：４５地点：布鲁塞尔实况录像 这是本届杯赛的第二场１／４决赛。开场后,双方打得都比较谨慎,意大利队依旧是老办法。先是一阵猛攻,而且他们的攻势也较有威胁。第７分钟,菲奥雷左路横传门前,因扎吉插上射门将球打偏。第１６分钟,托蒂在左路小角度凌空远射被守门员斯泰莱亚扑出。托蒂、因扎吉和菲奥雷的三角组合已经显示出很强的威力。第２６分钟,又是托蒂斜传右翼的因扎吉。因扎吉传中,菲奥雷凌空射门将球打高。 第３３分钟,意大利任意球被罗马尼亚队员顶出,菲奥雷在外围将球妙传禁区左侧,罗马尼亚队员造…     

Nutritional strategies to influence adaptations to training

This article highlights new nutritional concerns or practices that may influence the adaptation to training. The discussion is based on the assumption that the adaptation to repeated bouts of training occurs during recovery periods and that if one can train harder, the adaptation will be greater. The goal is to maximize with nutrition the recovery/adaptation that occurs in all rest periods, such that recovery before the next training session is complete. Four issues have been identified where recent scientific information will force sports nutritionists to embrace new issues and reassess old issues and, ultimately, alter the nutritional recommendations they give to athletes. These are: (1) caffeine ingestion; (2) creatine ingestion; (3) the use of intramuscular triacylglycerol (IMTG) as a fuel during exercise and the nutritional effects on IMTG repletion following exercise; and (4) the role nutrition may play in regulating the expression of genes during and after exercise training sessions. Recent findings suggest that low doses of caffeine exert significant ergogenic effects by directly affecting the central nervous system during exercise. Caffeine can cross the blood–brain barrier and antagonize the effects of adenosine, resulting in higher concentrations of stimulatory neurotransmitters. These new data strengthen the case for using low doses of caffeine during training. On the other hand, the data on the role that supplemental creatine ingestion plays in augmenting the increase in skeletal muscle mass and strength during resistance training remain equivocal. Some studies are able to demonstrate increases in muscle fibre size with creatine ingestion and some are not. The final two nutritional topics are new and have not progressed to the point that we can specifically identify strategies to enhance the adaptation to training. However, it is likely that nutritional strategies will be needed to replenish the IMTG that is used during endurance exercise. It is not presently clear whether the IMTG store is chronically reduced when engaging in daily sessions of endurance training or if this impacts negatively on the ability to train. It is also likely that the increased interest in gene and protein expression measurements will lead to nutritional strategies to optimize the adaptations that occur in skeletal muscle during and after exercise training sessions. Research in these areas in the coming years will lead to strategies designed to improve the adaptive response to training.

Major Accessions to Repositories in 2002 Relating to Sport

This article examines the genesis of and reactions to the six week strike by members of the New Zealand Cricket Players Association in late 2002 in which the primary focus was a claim for a 60 percent increase in pay. It argues that contrasting reactions to the strike among current and former players, cricket administrators, cricket fans and the media, must be understood in terms of a longer history of difficulty and dispute over players payment and representation in New Zealand cricket – a history that embodies a fundamental tension between the demands of professional cricket and the amateur ethos that characterised the New Zealand game from the late nineteenth century to the late 1970s.
