1999年是拉尔夫·舒马赫真正发挥了水平的一年。首站澳大利亚人奖赛就开了一个了个好头,为他的新车队获得了一个第三名。在巴西站夺得了第四名,在随后的比赛中,只要小舒马赫完成了比赛,他就肯定取得了积分,只是在自己家门口的德国大奖赛上打了一个盹。 相似文献

论“体教结合”和“教体结合”的同化与异化 总被引：1，自引：0，他引：1
王永安 《体育科技文献通报》2011,19(8):60-61,63
从“体教结合”和“教体结合”概念分析入手,阐述了“体教结合”和“教体结合”两种培养竞技体育人才模式的现状及发展情况。从概念的范畴、内容的指向性、发展目标、培养的思路、培养的理念等五方面探讨了“体教结合”和“教体结合”两种培养模式的趋同性;从所处地位、培养对象、培养形式、结合模式、学训方式,以及资源配置等方面探讨了二者之间存在的差异性。认为区分二者的异同点,将有助于我们进行理性的思考,科学的决策,不断促进我国体育事业的可持续发展。 相似文献

Fluid and electrolyte needs for preparation and recovery from training and competition 总被引：4，自引：0，他引：4
For a person undertaking regular exercise, any fluid deficit that is incurred during one exercise session can potentially compromise the next exercise session if adequate fluid replacement does not occur. Fluid replacement after exercise can, therefore, frequently be thought of as hydration before the next exercise bout. The importance of ensuring euhydration before exercise and the potential benefits of temporary hyperhydration with sodium salts or glycerol solutions are also important issues. Post-exercise restoration of fluid balance after sweat-induced dehydration avoids the detrimental effects of a body water deficit on physiological function and subsequent exercise performance. For effective restoration of fluid balance, the consumption of a volume of fluid in excess of the sweat loss and replacement of electrolyte, particularly sodium, losses are essential. Intravenous fluid replacement after exercise has been investigated to a lesser extent and its role for fluid replacement in the dehydrated but otherwise well athlete remains equivocal. 相似文献

普通高校田径教学模式研究 总被引：1，自引：0，他引：1

采取问卷调查、专家访谈、文献资料等研究方法，对普通高校田径课教学现状进行调查发现，田径课教学正面临巨大的困境。造成的主要原因是：教学内容陈旧，缺乏趣味性；教学方法单一，缺乏创新；组织形式呆板枯燥，使学生产生厌学情绪。考试评价体系标准规则化，定量化，使学生对掌握田径运动的实用性、健身性产生怀疑。思想认识与资源开发不足，使田径课教学失去有力保证。 相似文献

Soccer players should achieve an energy intake that provides sufficient carbohydrate to fuel the training and competition programme, supplies all nutrient requirements, and allows manipulation of energy or nutrient balance to achieve changes in lean body mass, body fat or growth. Although the traditional culture of soccer has focused on carbohydrate intake for immediate match preparation, top players should adapt their carbohydrate intake on a daily basis to ensure adequate fuel for training and recovery between matches. For players with a mobile playing style, there is sound evidence that dietary programmes that restore and even super-compensate muscle glycogen levels can enhance activity patterns during matches. This will presumably also benefit intensive training, such as twice daily practices. As well as achieving a total intake of carbohydrate commensurate with fuel needs, the everyday diet should promote strategic intake of carbohydrate and protein before and after key training sessions to optimize the adaptations and enhance recovery. The achievement of the ideal physique for soccer is a long-term goal that should be undertaken over successive years, and particularly during the off-season and pre-season. An increase in lean body mass or a decrease in body fat is the product of a targeted training and eating programme. Consultation with a sports nutrition expert can assist soccer players to manipulate energy and nutrient intake to meet such goals. Players should be warned against the accidental or deliberate mismatch of energy intake and energy expenditure, such that energy availability (intake minus the cost of exercise) falls below 125 kJ (30 kcal) per kilogram of fat-free mass per day. Such low energy availability causes disturbances to hormonal, metabolic, and immune function. 相似文献

Carbohydrates and fat for training and recovery 总被引：3，自引：0，他引：3
An important goal of the athlete's everyday diet is to provide the muscle with substrates to fuel the training programme that will achieve optimal adaptation for performance enhancements. In reviewing the scientific literature on post-exercise glycogen storage since 1991, the following guidelines for the training diet are proposed. Athletes should aim to achieve carbohydrate intakes to meet the fuel requirements of their training programme and to optimize restoration of muscle glycogen stores between workouts. General recommendations can be provided, preferably in terms of grams of carbohydrate per kilogram of the athlete's body mass, but should be fine-tuned with individual consideration of total energy needs, specific training needs and feedback from training performance. It is valuable to choose nutrient-rich carbohydrate foods and to add other foods to recovery meals and snacks to provide a good source of protein and other nutrients. These nutrients may assist in other recovery processes and, in the case of protein, may promote additional glycogen recovery when carbohydrate intake is suboptimal or when frequent snacking is not possible. When the period between exercise sessions is < 8 h, the athlete should begin carbohydrate intake as soon as practical after the first workout to maximize the effective recovery time between sessions. There may be some advantages in meeting carbohydrate intake targets as a series of snacks during the early recovery phase, but during longer recovery periods (24 h) the athlete should organize the pattern and timing of carbohydrate-rich meals and snacks according to what is practical and comfortable for their individual situation. Carbohydrate-rich foods with a moderate to high glycaemic index provide a readily available source of carbohydrate for muscle glycogen synthesis, and should be the major carbohydrate choices in recovery meals. Although there is new interest in the recovery of intramuscular triglyceride stores between training sessions, there is no evidence that diets which are high in fat and restricted in carbohydrate enhance training. 相似文献
