在《战国策·齐策》里面记载着一个脍炙人口的小故事。田忌和齐王赌赛马,两人相约:用上、中、下三等马各赛一场,确定最后的胜负。田忌情知自己的马儿不及齐王的同等马跑得快,如果不改变策略休想取胜。他权衡了一番,决定用自己的下等马对齐王的上等马,用自己的上等马对齐王的中等马,用自己的中等马对齐王的下等马。比赛结果,虽然下 相似文献

有位病人患了膑骨骨癌,经医生诊断,他必须截肢,这一辈子再也不能行走了。这位病人本身就是个医生,他决心与命运抗争,他一边服药,一边用意念给自己治病。每天,他抽出半小时闭目静养:他用意念调集全身的白细胞向病灶区域进攻,与癌细胞搏斗,并将癌细胞一个个杀死,在他的想象中,癌细胞尸横遍野,溃不成军,而白细胞却大获全胜。经过两个月的意念治疗,他能下地行走了。去医院检查,他身上的癌细胞竟然全部消失。连为他治疗的医生也感到惊讶,病人的确创造了一个人间奇迹。编辑于乐冰意念治病是心理疗法的一种,只要运用得当,它的确… 相似文献

第三次大战是在降了燕国,直下齐的都城临淄之后,齐王田广带10万败兵南下投楚项羽求援,项羽派大将龙且带兵20万和齐王联合北上进击韩信的汉高祖四年(公元前203年)十一月。这时韩信已拥有大军20多万,可是已派10万兵给属将灌婴进军东鲁击齐相田横,自己的兵力只及对方三分之一,而且已十分疲惫。韩信知道这是一场恶战,不出奇制胜,就全军覆灭。他喊来自己最亲密的钓鱼好友彭越,同在两军相持的潍水上游钓鱼。彭越字仲,昌邑(今山东金乡东北)人。原为巨野泽中渔民。秦末聚众起义,楚汉战争时,率3万人归刘邦,占领彭城。项羽自齐南下击溃刘邦,刘邦只身西… 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
