发帖数: 3071 | 2 In anatomy, the core refers, in its most general of definitions, to the body
minus the legs and arms. Functional movements are highly dependent on the
core, and lack of core development can result in a predisposition to injury
. The major muscles of the core reside in the area of the
belly and the mid and lower back (not the shoulders), and peripherally
include the hips, the shoulders and the neck. |

先放结论：
跑步等有氧运动，长期有氧运动，可能会让食欲升高↑。让身体处于增加体脂体重状态。
无氧运动则相反，长期力量训练，可能会让食欲降低↓。让身体处于减少体脂体重状态。
这也就是说，如果你长时间从事跑步或骑自行车等运动，你的食欲可能会越来越好哒~
（实际上的运动后短时间内食欲，会有诸如交感神经兴奋、肾上腺素分泌、皮质醇等问
题的影响。我只说的是科学研究的长期情况。不一定和你自己的体验相一致，不要跟我
辩你什么运动后会饿，什么不会……）
但如果长期进行无氧运动，食欲却反而可能会降低，或者没有太大变化。
短期运动的话，结论可能正相反，不过由于短期内的实验容易受诸多因素影响，所以对
现实的指导意义不大，就不要太在意啦~而且眼光也要放长远一点对不对~

所以在7D或5D2上用xxb, 540等一系列F4.0的镜头，两者对焦精度应该一样，
只有1D系列机身，在F4仍然是高精对焦。
