发帖数: 1733 | 1 篮球我是外行，但我想所有对抗性运动的基本道理都是一样的。运动场的performance
提高，离不开身体素质训练，包括力量，爆发力，耐力，平衡力等等，而且这些能力还
必须在对抗的情况下能表现出来。我对训练的几点心得
1。高强度训练， 但要适可而止。 多做HIIT
2。训练中身体work as a unit,
3。core strength 及其重要
4。一定要读理论，了解身体
贴几篇文章给你读一下，希望对你有些帮助

At a gymnastics or martial arts meet, or at a weightlifting competition,
listen to the coaches advice to the athlete – Stay tight! This means to
maintain stiffness. Being stiff ensures that there will be minimal energy

The depressing action of superior oblique (making the eye look down towards
the mouth) is most effective when the eye is in an adducted position. This
is because as the eye is abducted (looks laterally), the contribution made
by superior oblique to depression of the eye decreases, as the inferior
rectus muscle causes this movement more directly and powerfully. The main
muscle for abduction is the lateral rectus, so although superior oblique
contributes to a downwards and lateral eye mov |

crunch 的益处。
在一片对crunch 的喊打中，站出来告诉大家，crunch是有利的，只有你注意你的姿势
。crunch，的动作是平躺，髋部90度。抬肩，头离地，腹部收紧，胸部向上向前。同时
保持背部贴紧地面。crunch 主要是用到 rectus abodominis 和一些 obliques.
crunch 的益处在于提高了腹部肌肉的力量和耐力，有助于提高对脊柱的支撑，同时保
持了脊柱的活动范围（range of motion).
对于每天坐着工作的，问题是腹肌太弱，腰部的肌肉（erector spinae muscles）太紧
张, 引起脊柱变形，需要crunch来帮助矫正姿势。
从运动解剖和运动机能上讲，脊柱的活动范围（range of motion）主要是受到连接的
肌肉限制的。所以说crunch会压迫到脊柱根本就是无稽之谈。
腹部肌肉的耐力和力量是有限的，所以可以一次做上百的crunch的同学，你的姿势肯定
是有问题的，如果这样伤到脊柱，那是运动姿势的问题，和crunch无关。

发帖数: 1644 | 11 在过去的一年中，前大半年基本上是跑Treadmill，后几个月换成以Crossramp为主, 偶的天，
发现Crossramp是个好东西，个人的体会是比Treadmill好，有如下几个事实：
１：跑Crossramp后，无论跑多久，膝盖不会痛，所以就不担心老了膝盖出问题。
２：跑Crossramp，感觉对心脏的训练强度，根本不比Treadmill差，同样时间里显示板
上烧的Calories还多，当然这个数字是有保留的，但身体感觉还是有说服力的。
３：跑Crossramp,大小腿四个部分的肌肉都锻炼到了，可以代替一些LEG Extension的
机械运动，节省时间
４：跑Crossramp完之后，感到还有很多余力进行器械运动。
像刚才，setup crossram 20, resistence10的情况下，跑一个小时，６.８Miles,显示
消耗７９０Calories，然后我接下来做了半个小时机械，包括abdominal，abdominal

Muscles targeted: rectus abdominis
Lie with your back on the floor. Place your hands by your sides with palms
down on the floor.
Bring your knees in towards your chest until they're bent to 90 degrees,
with feet together.
Tense up your abs and curl your hips off the floor.
Lower and repeat for 15-20 reps.
Use your abs to lift your hips rather than swinging your legs and creating
momentum.

someone hold your feet. Not only does this mistake cause harmful stress to

最深的是transverse abdominus，顾名思义，是完全横向肌肉
然后是两个斜向external oblique, internal oblique
最外层，是我们俗话说的6 pack--rectus abdominus
如果做仰卧起坐，整个一个大肌肉群，都在动，每个肌肉的受力非常有限。
除非你做１千个，，，，每天做个１００－２００个，起影响可以忽略不计。。。
