来自主题: Pingpong版 - fs1兄弟膝盖受伤了?
既然问了,就稍多写一些。不是BSO或求Blessing(thanks for the blessing though)
,只是给大家科普一下,以有个概念(但不求100%科学正确)。
Left knee medial meniscus tear:左膝内侧半月板撕裂。
一个膝盖关键的部分就是那些韧带(四条)、股/髌/胫骨的软骨、和半月板(两个)。
这些都可以损伤、撕裂和破裂,韧带也可以全断。受伤了就发炎、积水、更痛。
半月板附着在小腿骨的最上端,和大腿骨最下端软骨可以有相对运动。半月板本身也是
软骨。
半月板损伤非常常见,一是运动导致,一是日积月累所用导致。一般是关节镜手术切除
裂掉的部分。林书豪去年做过此手术,Lakers' Metta World Peace也刚做过。
我的膝盖痛了一些时日,不过打球时不痛,奇怪有时打球还会让疼痛感好些。终于一月
多前痛/肿难忍,就挂拍开始找医生了。现在仍然不知是打球所致还是搬重物所致,并
不是某一天就疼得突然不能动了。
我的一个医生倾向手术,另一个倾向暂时不做。我现在想的是先修养半年再说。一月悠

Initially I was planning to just run half because of

straight.
The major difference between RDL and DL:
RDL: a hip dominant movement
DL: a quad dominant movement.
RDL is a perfect complementary movement to squat, a posterior chain
movement vs. a frontier chain movement.

and this one, bench press is easy to achieve, but 2x squats is way too much
more difficult for normal people, since most of people tend to have a weak
posterior chain, I did not see anyone who has successfully pass their 1.5x
squat without an injury, except professionals:
However, after a certain threshold of development – say a 1.5 x bodyweight
bench press, a 2 x bodyweight squat, and a 2.5 x bodyweight deadlift – it's

大多数讨论是在没有清晰界定剽窃标准的前提下进行的。例如,讨论中出现的“参见式
抄袭”、“注释式剽窃”等等就是很不负责任的概念。以这样的概念和界定对学术著作
进行甄别,不但混淆了正常学术研究与剽窃的区别,而且也为学术工作制造了人为的混

Lust 就是我们所说的性吸引。而爱是一种非常特殊的情感——与焦虑、恐惧、抑郁等

当你对某人拥有强烈的性冲动时,你很有可能误以为那种浪漫的吸引力就是爱情。但对

doesn't make it LOVE.

芝加哥大学 Stephanie Cacioppo 团队的研究结果表明,性冲动(lust)与爱意(love
)会调动大脑的不同区域。
当你感觉到强烈的性冲动时,后脑岛(posterior insula)——更多地用来控制感觉(
如痛感)的区域变得活跃起来;而在你想表达爱意时,前脑岛(anterior insula)则
被激活——这也是引起愤怒、厌恶等情绪的区域。
