贾森·特里 :等待起飞

贾森·特里过去常穿着大学校队的运动服躺在床上,有一次、NCAA锦标赛上,他连续11投不中、只是因为他没有穿他的幸运袜。他还喜欢穿着当天晚上比赛对手的短裤,每场比赛之前,他都吃鸡爪子。这是一个非常迷信的人,他不会改变自己这些关于篮球的独特癖好。有趣的是,一个戏剧性的变化影响了他的NBA职业生涯。1999年、亚特兰大鹰队在选秀会上选中贾森·特里时、认为这位身高1.88米的年轻人适合组织后卫这个位置。他们忘了特里1998~1999赛季在NCAA太平洋赛区十强中以平均每场21.9分名列得分榜首,他们不关心特里在赛场上"得分至上"的观点,特里身高1.88米,所以他应该是组织后卫,唉,那个时代!坏消息。特里平均每场比赛8.1分,投篮命中率仅有41.5%.而三分线外的投篮命中率仅有29.3%,这位选秀会上的第10名在不断下滑,任何一种迷信仪式或其他什么活动都救不了他."我总是想着其他人."他说,"我没有想自己投篮,所以,我应该加油了."罗恩.科拉格认识到了这一点,上赛季他接手亚特兰大鹰队时,便发现特里的位置错了,如同硬要把一个方形的木塞塞进圆洞里,如同让诗人去拉犁. 最后,得分后卫贾森.特里又在他的种种迷信行为列表中添加了新的一项,那就是——胜利!     

Differences between the sexes in the three-dimensional angular rotations of the lumbo-pelvic-hip complex during treadmill running

The aims of this experiment were to determine whether there are differences between the sexes in the three-dimensional angular rotations of the lumbo-pelvic-hip complex during running and, if such differences exist, to establish whether factors other than sex can explain the observed differences. A cohort of 44 non-injured runners (22 males, 22 females) who usually ran more than 20 km per week were voluntarily recruited. All trials were conducted on a treadmill at a running speed of 4.0 m x s(-1). Reflective markers were placed over specific anatomical landmarks of the thoraco-lumbar spine, pelvis and femur. Data were captured using a VICON motion analysis system. Females tended to display a greater peak-to-peak oscillation for most of the angular rotations. An offset was the main difference between the male and female group mean waveforms for pelvis anterior-posterior tilt. Forward stepwise regression analysis revealed that sex was the most common variable related to the amplitudes of the angular rotations. Given these results, sport scientists conducting future biomechanical studies using angular data to test hypotheses are advised to be extremely cautious about averaging across male and female participants.     

Simultaneous measurement of back and front foot ground reaction forces during the same delivery stride of the fast-medium bowler

Six male cricket bowlers (mean +/- s(mean): age 23.5 +/- 1.3 years; height 1.83 +/- 0.04 m; body weight 826 +/- 20 N) performed their typical bowling action at a set of stumps positioned at standard pitch length (20.1 m). A specially designed force platform rig allowed the correct positioning of two force platforms to be achieved beneath an outdoor polyflex runway (0.017 m depth) for each player's delivery stride pattern. For the back foot, the peak vertical ground reaction force was 1.95 +/- 0.08 kN (2.37 +/- 0.14 BW) and the braking force was 0.77 +/- 0.12 kN (0.94 +/- 0.16 BW). For the front foot, the peak vertical force was 4.80 +/- 0.92 kN (5.75 +/- 0.98 BW) and the braking force was 2.93 +/- 0.56 kN (3.54 +/- 0.67 BW). The mean peak vertical loading rate for front foot contact was 205 +/- 52.8 kN x s(-1) (249 +/- 64 BW x s(-1)) with mean values ranging from 81 to 446 kN x s(-1) (98 to 540 BW x s(-1)). The range for back foot contact was much smaller, 25-70 kN x s(-1) (30-85 BW x s(-1)), with a mean of 41.7 +/- 7.10 kN x s(-1) (50.6 +/- 8.6 BW x s(-1)). Mean peak impact occurred 24 ms after touchdown for the back foot and 16 ms after touchdown for the front foot. At impact, mean peak loading rates were greater for the front foot at 246 kN x s(-1) (298 BW x s(-1)), with a range of 80-483 kN x s(-1) (98-534 BW x s(-1)), than for the back foot at 65 kN x s(-1) (79 BW x s(-1)), with a range of 40-84 kN x s(-1) (49-110 BW x s(-1)).     

世界杯太太

和孩子他爸一直天各一方,每 年都是到了春节或是暑假探亲才能小聚几日。然而,六月初的一天,他在电话中小心翼翼地提示我,可不可提前休探亲假?我立即识破了他的企图:世界杯在即,他准是希望半夜观球时有人送上冰凉的啤酒和热乎乎的毛巾……但他很委屈地解释,世界杯对我而言,比春节还重要,重要的时刻嘛,总是想老婆孩子能在身边分享！ 我在这番花言巧语中迅速地陶醉了一分钟,然后便着手准备,终于赶在世界杯开幕式那夜携女儿飞来北京。

“后乔丹时代”的NBA

在球迷们的心目中,乔丹是永远战无不胜的。他可以战胜每一个对手,他可以战胜每一次病痛,他甚至可以战胜地心引力,高高飞在空中。但是这一次,终于来了一位乔丹无法战胜的敌人——岁月。岁月不留情,它使乔丹的反应不再敏捷,它使乔丹的身手不再矫健,它使乔丹再也不能飞翔。“上帝派到人间昭示篮球真谛的天使”也许要休息了。每一位球迷部在担心,担心乔丹退役后所留下的巨大空白,担心后乔丹时代的 NBA 将或多或少地失去几分绚烂的色彩。但是,球迷总还得看球,总还得对未来有几分期待。对球迷来说,看和乔丹生活在同一时代是一种幸福;对球员来说,和乔丹生活在同一时代却是一种悲哀,对于这一点“邮差”马龙“铁
