<正> 三、运球技术训练运球技术是控制球、支配球、组织战木配合及突破防守的重要手段,是一项重要的进攻技术。熟练地掌握运球技术,对提高脚步动作、传球、突破以及投篮等技术都有促进作用,尤其对青少年篮球运动员来说,熟练地掌握运球技术具有更重要意义。运球技术训练注意事项: (1)在正确掌握各种运球技术基础上,巩固形成正确的运球技术定型,提高控制球、支配球和保护球的能力。要注意由简到繁、由易到难、由慢到快的     

第28届奥运会中外男篮中锋防守意识比较研究

中锋由于其职责和位置的关系,其防守能力的强弱将直接影响球队的整体防守水平。防守意识是构成防守能力的重要方面。运用录像分析等研究方法,从区域防守意识、防守选位意识、身体对抗意识、协防与补防意识、抢防守篮板球意识、封盖意识等六个方面,对参加第28届奥运会的中外男篮中锋21人进行了比较分析,结果显示,除封盖意识外,我国中锋在其他5个方面与国外高水平中锋相比都存在一定差距。     

时空视阈下2018年首届女篮世界杯中国队攻防效果解析

以辩证唯物主义时空观理论为依据,阐明篮球运动的时空对抗特点及时间与空间之间的辩证关系,归纳概括篮球时空观,并在其视阈下,运用文献资料法、访谈法、录像观察法、数理统计法对2018年西班牙首届女篮世界杯中国队的攻防效果进行解析。研究结果表明:篮球运动时间要素的对抗主要体现为速度的制衡,空间要素的对抗包括地面位置及其垂直空间的立体对抗。时间和空间要素彼此转换、相辅相成、互为因果。表现为球队进攻效果的速度方面:中国女篮快攻质量高、衔接段进攻薄弱;向篮突破和空切的数量较多,但进攻效率低,整体质量不高。主要体现空间对抗进攻效果方面:油漆区空间进攻较多,对篮下攻击力增强,但是三分区空间的进攻质量较差。表现中国女篮防守效果的速度方面:防守对手向篮突破和空切的质量不高,防守整体性较差。主要体现空间对抗防守效果方面:中国女篮的全队拼抢空中篮板球能力,尤其是外线队员,与世界强队相比,存在一定差距;集体协作拼抢位置及空间的能力较弱,对低位中锋的协防意识欠缺。

篮球比赛中传球前假动作的运用

在激烈的篮球比赛中,传球技术是攻击的重要手段、是队员之间的配合基础。比赛中的快攻、传切、策应、供中锋、突破、分球等一系列配合都是通过传球来进行的。为了获得良好的传球机会,保证使球安全地超越自己的防守人,及时传球给同队队员,除了提高传球的突然性和隐蔽性的技巧之外,结合运用传球前的假动作,诱使防守人移动位置或重心,则效果更好。     

Carbohydrate ingestion improves endurance performance during a 1h simulated cycling time trial

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.     

Science and medicine of rowing: A review

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.

Identifying home advantage in international tennis and golf tournaments

A regression analysis of competitors' tournament results in relation to their world rankings was proposed to identify the effect of home advantage in international ‘grand-slam’ tennis and ‘major’ golf tournaments. The results provided little evidence of home advantage in either the grand-slam tennis or the golf tournaments held in 1993. The only possible evidence of home advantage was found in the Wimbledon tennis and the US Open golf championships. Even these findings can be explained, at least partially, by (1) the availability of information concerning the low world rankings of the British tennis players competing at Wimbledon, and (2) selective entry, allowing only the world's top-ranked foreign golfers into the US open golf tournament. In both cases, the lower ranking home competitors have a greater opportunity to perform above their anticipated world rankings. Therefore, provided entry into tennis and golf tournaments is truly ‘open’ to both the host nation's representatives and foreign competitors alike, home advantage does not appear to be a major factor influencing the competitors' performance in such competitions. These findings may be explained by the relatively objective nature of the scoring systems used in tennis and golf, unlike the subjective influence of refereeing decisions on the results of team-games such as soccer.
