没有范志毅的冲天名气．没有申思的名警被身,也没有成问东的历练老道,但吴承瑛仍然堪称是申花队乃至中国足坛一道竺沙的风景线。在绿茵场上,吴永成简直就像一匹脱恒的里马,有使不尽的力气。更让人艳羡、也让人嫉妒的是这段B于他总是在危惜时到担城拔案,让对手在桂叹无条中败下阵来。人们很难忘记去年11月申在客场迎战八一队的那一幕,是吴承成突入禁区一记冷射攻进了申花队全场的唯一进球,他做着怀抱在儿的动作来庆祝队友刘军面获员于。对前卫农岛队的比赛他又连下两城,让黑脸严德俊变成红脸亦不解基。塔说大连万达参加亚俱杯赛,是… 相似文献

正这是我看到的最令人动容的实寄封和信札。夜深了,我合上眼睛却无法入睡。书桌上静静地放着一件老实寄封,它的里面有一封深情绝笔的家信,被时光默默地保存下来。实寄封不会说话,但它会讲故事,就像拥有灵魂一样。虽然故事只是千千万万中的一个片段,但我还是想为它写一篇文章,记录它的故事,纪念故事里的主人公,追忆和主人公一样千千万万逝去的人们。"何必花时间写一篇文章?在普通人眼里它只是平凡无味的实寄封。"邮友不解地问。"因为它打动了我。"我安静地 相似文献

“大地在颤抖,仿佛空气在燃烧。暴风雨来了。”20年前一部南斯拉夫电影中的台词至今令人不忘。阐释它的,是NBA新的赛季。 似乎规则有了根本的改变,“赢球靠防守”已不再是真理。进攻吧,为世纪末最后的疯狂,为新生代最全面的崛起,在那个缩水的赛季匆匆离去之后,新的人类对古旧教条的背叛显得更为迫切,更加彻底。 相似文献

<正> “相思不尽又相思,潍水青光处处迟。隔岸桃花三十里,鸳鸯庙接柳郎祠。纸花如雪满天飞,娇女秋千打四围。五色罗裙风摆动,好将蝴蝶斗春归。”郑板桥的这首诗道出了潍坊风筝的特色。阳春三月,潍城上空飞满了形态各异的风筝。每年4月1日至10日的潍坊国际 相似文献

问题图(取材于韩国第4届棋圣战挑战赛七番胜负第六局,挑战者李昌镐六段执黑对棋圣曹薰铉九段):白1刚刚守角,黑2就跟进破空。白3不在左边定型,而是抢先在上边制造纠纷,黑方应如何应对。实战经过图:白6改于25位高拆也是常见之着。参考图一:黑2小飞挂时,白3一间低夹可下。进行到黑12挂角是极普通的局面。由于实战白6低拆,白8再低夹似乎有些不妥。弈至白14定式告一段落,白6显得位置欠佳。参考图二:白1高夹是可行的一策。黑2至12的应对,双方均可接受。白13与黑14变换后,再顺势于15位拆补,白 相似文献

人们说眼睛是心灵的窗户。拥有一双健康的眼睛，对生活、学习、尤其是就业有着非常重要的意义。生活中这样的例子比比皆是。我的邻居佟某，本来毕业于北京某重点大学，但五次应聘均被用人单位拒绝，因为每次负责招聘的人事主管都会直接地告诉他：“你近视度数太高了。”所以现在的佟某真后悔以前没有好好保护眼睛。高一时，他只是有点看不清黑板上的字，他妈妈给他配了眼镜，但他并不在意，没有坚持配戴。到高中毕业时，他的视力已达到600多度。现在的视力已超过了1000度，这给他的外貌、生活以及就业带来了严重影响。以至现在，一提到眼睛… 相似文献

踝关节跖屈肌肌肉肌腱形态及收缩效应的相关研究 总被引：2，自引：0，他引：2
应用螺旋CT及体视学研究方法对普通大学生踝关节跖屈肌肌肉肌腱形态进行了较全面的测量分析,同时采用六维测力平台结合表面肌电测量仪测定最大跖屈力,探讨跖屈肌肌肉肌腱形态与收缩效应之间的关系。结果表明:①小腿跖屈肌横断面积、体积和小腿围度与肌肉力量之间存在密切的关系;②小腿长、腓肠肌长、比腓肠肌肌腱长与肌力有着明显的相关;比目鱼肌长只与提踵肌力有关;③跟腱长、比跟腱长和腓肠肌肌腱长与肌力之间不具相关性。 相似文献

目的：探讨肌肉疲劳后，被动(Passive Recovery，PR)、主动(Active Recovery，AR)、振动(Vibration Recovery，VR)和冰敷(Cryotherapy Recovery，CR)等不同恢复方式对肌肉表现(最大肌力MVC、爆发力MP、肌肉激活程度sEMG)和力学特性(肌肉硬度MS、肿胀程度SD)的影响及差异。方法：20名身体健康的普通男性大学生为受试者，平均年龄(20.4±2.3 yrs.)，平均身高(173.5±3.4 cm)，平均体重(68.7±3.9 kg)。先测量非惯用手肱二头肌的SD、MS、MVC和sEMG，之后进行肘关节屈曲45°/s向心与离心收缩运动直至疲劳，再进行后测。其后以随机方式进行其中1种恢复，10 min恢复后立即进行后测，各恢复方式间隔7天。以单因素重复测量方差分析检验SD、MS、MVC和sEMG在不同检测时间点的差异及恢复效果。结果：10 min VR和CR均有约15%的力量恢复效果，其中VR介入后sEMG的恢复效果显著高达(32.50±16.10%)。另外，CR可以缓解疲劳后的SD，但AR后SD(28.51±2.79 cm)显著高于疲劳前(27.93±2.93 cm)，且MS(11.14±1.58 mm/2kg)相较于疲劳后(11.59±1.40 mm/2kg)也显著下降。结论：CR与VR均可有效帮助疲劳后的肌力恢复，2组间恢复效果无显著差异；同比之下AR则无法改善肌肉疲劳的恢复，甚至造成SD增加且MS降低。 相似文献

ABSTRACTLow back pain (LBP) is a common problem in football (soccer) players. The effect of LBP on the trunk and hip muscles in this group is unknown. The relationship between LBP and trunk muscle size and function in football players across the preseason was examined. A secondary aim was to assess hip muscle strength. Twenty-five elite soccer players participated in the study, with assessments conducted on 23 players at both the start and end of the preseason. LBP was assessed with questionnaires and ultrasound imaging was used to assess size and function of trunk muscles at the start and end of preseason. Dynamometry was used to assess hip muscle strength at the start of the preseason. At the start of the preseason, 28% of players reported the presence of LBP and this was associated with reduced size of the multifidus, increased contraction of the transversus abdominis and multifidus muscles. LBP decreased across the preseason, and size of the multifidus muscle improved over the preseason. Ability to contract the abdominal and multifidus muscles did not alter across the preseason. Asymmetry in hip adductor and abductor muscle strength was found between players with and without LBP. Identifying modifiable factors in players with LBP may allow development of more targeted preseason rehabilitation programmes. 相似文献

Abstract The aim of the present study was to analyse differences in muscle response and mechanical characteristics of the vastus medialis, rectus femoris, vastus lateralis, and biceps femoris in elite volleyball players of both sexes using tensiomyography. To this end, 47 players of nine nationalities playing for teams in the men's and women's Spanish Superleagues were assessed. The sample comprised 22 women (age 24.6±4.3 years; weight 72.14±10.06 kg; height 178.40±8.50 cm) and 25 men (age 25.0±4.3 years; weight 88.76±9.07 kg; height 194.71±7.84 cm). Tensiomyography was used to assess muscular response and muscular mechanical characteristics. For this purpose, the following variables were analysed: maximum radial displacement of muscle belly and normalized response speed. The findings show, both in men and women, a higher normalized response speed score in the vastus lateralis and vastus medialis compared with the rectus femoris and biceps femoris. A marked lateral symmetry of maximum radial displacement of the muscle belly was also observed in the musculature of the lower limbs, with no statistically significant differences being detected in either men or women. There were, however, clear differences in terms of normalized response speed between male and female volleyball players: women displayed a more pronounced difference in the normalized response speed of the musculature responsible for extension (vastus medialis, rectus femoris, and vastus lateralis) and flexion (biceps femoris) of the knee joint than men. Moreover, tensiomyography proved to be a highly sensitive tool for detecting such changes. 相似文献

The primary study objective was to identify determinants of short-term recovery from a 161-km ultramarathon. Participants completed 400 m runs at maximum speed before the race and on days 3 and 5 post-race, provided a post-race blood sample for plasma creatine kinase (CK) concentration, and provided lower body muscle pain and soreness ratings (soreness, 10-point scale) and overall muscular fatigue scores (fatigue, 100-point scale) pre-race and for 7 days post-race. Among 72 race finishers, soreness and fatigue had statistically returned to pre-race levels by 5 days post-race; and 400 m times at days 3 and 5 remained 26% (P = 0.001) and 12% (P = 0.01) slower compared with pre-race, respectively. CK best modelled soreness, fatigue and per cent change in post-race 400 m time. Runners with the highest CKs had 1.5 points higher (P < 0.001) soreness and 11.2 points higher (P = 0.006) fatigue than runners with the lowest CKs. For the model of 400 m time, a significant interaction of time with CK (P < 0.001) indicates that higher CKs were linked with a slower rate of return to pre-race 400 m time. Since post-race CK was the main modifiable determinant of recovery following the ultramarathon, appropriate training appears to be the optimal approach to enhance ultramarathon recovery. 相似文献
