为了使更多的青少年重新回到田径场,让他们跑起来、跳起来,重新喜欢田径运动,增加田径运动的基础人口,国际田联在2000年就推出了趣味性的田径运动,旨在以灵活有趣的田径运动形式,吸引青少年参加田径锻炼。从本期开始,本刊同“国际田联地区发展中心·北京”合作,向读者连续介绍《国际田联青少年发展规划》及图文并茂的趣味田径运动——《少儿田径运动教学卡片》和《趣味田径游戏》等。 相似文献

最近,我在《体育教学与训练》上看到了两篇否定田径运动是各项运动基础的文章,一篇是黄绍勤同志的《对田径运动是各项运动的基础的质疑》(刊于该刊1983年第四期),另一篇是吴太平同志的《田径运动是各项运动的基础的理论值得修正》(以下简称《质疑》和《修正》)。《质疑》从田径运动的动作形式和田径运动对发展专项身体素质的作用进行分析,同时还列举了我国许多优秀运动员田径运动能力都属于一般的例子,来论证田径运动不 相似文献

对近些年来我国出版的多个版本的田径运动教科书中给田径运动概念所下的定义提出不同看法,认为用《田径竞赛规则》中所写的"田径运动包括径赛和田赛、公路跑、竞走、越野跑和山地赛跑"作为田径运动的定义写入教科书不妥。《国际田联章程》中并没有给田径运动下定义,而只是对田径竞技包含的项目做了简要说明。外国只有"田径竞技"这个概念,而没有"田径运动"这个概念。中国的田径运动这个概念虽然翻译自外国(最初翻译为田径赛),但发展至今,中国的田径运动与外国的田径竞技已存在区别。在高等学校教科书中给概念下定义,必须遵循逻辑学关于给概念下定义的方法与规则并符合中国的实际情况。田径运动是走、跑、跳、投的身体运动,包括田径竞技运动和田径健身运动。 相似文献

This study examined the effect of carbohydrate ingestion on metabolic and performance-related responses during and after a simulated 1h cycling time trial. Eight trained male cyclists (VO 2 peak = 66.5ml kg -1 min -1 ) rode their own bicycles mounted on a windload simulator to imitate real riding conditions. At a self-selected maximal pace, the cyclists performed two 1h rides (separated by 7 days) and were fed either an 8% carbohydrate or placebo solution. The beverages were administered 25 min before (4.5ml kg -1 ) and at the end (4.5ml kg -1 ) of the ride. With carbohydrate feeding, plasma glucose tended (P = 0.21) to rise before the time trial. Compared with rest, the plasma glucose concentration decreased significantly (P < 0.05) at the end of both rides, with no statistically significant difference being observed between treatments. Thereafter, plasma glucose increased significantly (P < 0.05) at 15 and 30 min into recovery, and was significantly higher at 30 min during the carbohydrate trial compared with the placebo trial. No significant changes in plasma free fatty acids were observed during the ride. However, a significant increase (P < 0.05) in free fatty acids was found at 15 and 30 min into recovery, with no difference between trials. Mean power output was significantly (P < 0.05) greater during the carbohydrate compared with the placebo trial (mean - S.E.: 277-3 and 269-3W, respectively). The greater distance covered in the carbohydrate compared with the placebo trial (41.5-1.06 and 41.0–1.06km, respectively; P < 0.05) was equivalent to a 44s improvement. We conclude that pre-exercise carbohydrate ingestion significantly increases endurance performance in trained cyclists during a 1h simulated time trial. Although the mechanism for this enhancement in performance with carbohydrate ingestion cannot be surmised from the present results, it could be related to a higher rate of carbohydrate oxidation, or to favourable effects of carbohydrate ingestion on the central component of fatigue. 相似文献

The biology and medicine of rowing are briefly reviewed. Effort in a 2000 -m race is about 70% aerobic. Because the boat (and in some instances a cox) must be propelled, successful competitors are very tall, with a large lean mass and aerobic power. Large hearts may lead to erroneous diagnoses of a cardiomyopathy. Large respiratory minute volumes must be developed by chest muscles that are also involved in rowing. The vital capacity is typically large, and breathing becomes entrained. Expiration cannot be slowed relative to inspiration (as normally occurs at high rates of ventilation) and the limiting flow velocity may be reached, with the potential for airway collapse. Performance is strongly related to the power output at the ‘anaerobic threshold’, and lactate measures provide a guide to an appropriate intensity of endurance training. Peak blood lactate levels are higher in males (commonly 11–19 mmol·l -1 and occasionally as high as 25 mmol·l -1) than in females (9–11 mmol·l -1), probably because males have a greater muscle mass in relation to blood volume. The skeletal muscles are predominantly slow twitch in type, developing an unusual force and power at low contraction velocities. Many rowers have a suboptimal diet, eating excessive amounts of fat. Lightweight rowers also have problems of weight cycling. Aerobic power and muscle endurance often change by 10% over the season, but such fluctuations can be largely avoided by a well-designed winter training programme. Injuries include back and knee problems, tenosynovitis of the wrist and, since the introduction of large blades, fractures of the costae. 相似文献

影响和限制耐力性运动项目的成绩的生理因素是复杂的和多方面的,取决于训练的强度和运动成绩.大强度持续性运动可导致呼吸肌疲劳.运动性呼吸疲劳可能在决定运动耐量方面起到关键的作用：一方面通过直接影响运动肌力量的生成（外周疲劳）,另一方面,通过肢体用力自感不安反馈引起工作肌运动单位输出功率下降（中枢疲劳）.对呼吸肌进行训练,可能有助于提高耐力性项目的运动成绩. 相似文献
