目的:研究我国游泳项目优秀运动员的膳食结构、营养状况及存在问题,提出营养保障措施。方法:对19名运动员进行为期3天的膳食调查,以及高原初期和后期的生化指标的测定,数据通过运动员营养软件统计处理进行分析。结果:30%的运动员总热能摄入量仅占推荐量的80%以下,尤其女运动员偏差较大,三大热源质比例为碳水化合物占41%,脂肪占42%;蛋白质占17%,三餐热能摄入比例不合理,蔬菜摄入总体显示不足。血象指标分析显示,血红蛋白提高者占63%,红细胞数提高者占68%,红细胞压积提高者占63%。运动员训练前、后体重变化平均在0.4～0.8kg之间,控体重的运动员血象指标出现下降的倾向,运动员平均摄水量为3.5l/d。结论:高原训练中,运动员的膳食监测和营养补充是提高运动能力的重要保障。 相似文献

Winter sports are played in cold conditions on ice or snow and often at moderate to high altitude. The most important nutritional challenges for winter sport athletes exposed to environmental extremes include increased energy expenditure, accelerated muscle and liver glycogen utilization, exacerbated fluid loss, and increased iron turnover. Winter sports, however, vary greatly regarding their nutritional requirements due to variable physiological and physique characteristics, energy and substrate demands, and environmental training and competition conditions. What most winter sport athletes have in common is a relatively lean physique and high-intensity training periods, thus they require greater energy and nutrient intakes, along with adequate food and fluid before, during, and after training. Event fuelling is most challenging for cross-country skiers competing in long events, ski jumpers aiming to reduce their body weight, and those winter sport athletes incurring repeated qualification rounds and heats. These athletes need to ensure carbohydrate availability throughout competition. Finally, winter sport athletes may benefit from dietary and sport supplements; however, attention should be paid to safety and efficacy if supplementation is considered. 相似文献

The referee has responsibility for control of players' behaviour during competitive football and implementing the rules of the game. To do this, the referee and the two assistant referees are obliged to keep up with play. Referees cover 10,000 m on average during a game, mean heart rate is about 160 - 165 beats . min(-1) and oxygen uptake is close to 80% of maximum (VO(2max). Assistant referees cover approximately 7500 m, mean heart rate is about 140 beats . min(-1) and the corresponding oxygen uptake is 65% VO(2max). Both groups display evidence of fatigue towards the end of the game, a phenomenon that has not been thoroughly examined for nutritional interventions. The estimated energy expenditure of referees during a game exceeds 5600 kJ. Both referees and assistant referees execute unorthodox patterns of movement during match-play that increase energy expenditure over normal locomotion. As high standards of fitness and decision making are expected of professional referees, there are nutritional consequences associated with the training regimes they adopt. The effects of nutritional interventions on cognitive performance during the later stages of a game are in need of further investigation. 相似文献

Throwers, jumpers, and combined events athletes require speed, strength, power, and a wide variety of technical skills to be successful in their events. Only a handful of studies have assessed the nutritional needs of such athletes. Because of this, recommendations for nutritional requirements to support and enhance training and competition performances for these athletes are made using research findings from sports and exercise protocols similar to their training and competitive events. The goals of the preparation cycle of nutrition periodization for these athletes include attaining desirable body weight, a high ratio of lean body mass to body height, and improving muscular power. Nutritional recommendations for training and competition periods include: (1) meeting energy needs; (2) timing consumption of adequate fluid and electrolyte intakes before, during, and after exercise to promote adequate hydration; (3) timing consumption of carbohydrate intake to provide adequate fuel for energy demands and to spare protein for muscle repair, growth, and maintenance; (4) timing consumption of adequate protein intake to meet protein synthesis and turnover needs; and (5) consuming effective nutritional and dietary supplements. Translating these nutrient and dietary recommendations into guidelines these athletes can apply during training and competition is important for enhancing performance. 相似文献
