b-p也喜欢jogging？握手！

不过你深更半夜的上那儿去jogging了，不是干啥坏事去了吧。

就在楼下操场上黑了咕咚的跑圈，坏事没干，倒是担心被坏事。

大家都消停了，我还没睡呢。 又仔细的看了录像，读了帖子。 我刚发现， Bingster新贴的录像不是大回转哪，只能算mediem radius turn， Bingster自己认为是大回转，我不认同。当然我早歇菜了，Bingster要是认为坚持自己转的是大弯，我支持，这就是大弯，大王说几就是几。

没雪得日子，不较劲没意思呀。 大家别认真，也别停，继续继续。。。

而且我感觉呀，当然我不是hh或者lito， 大回转应该比小回转速度快呀。当然啦，高手无论大小回转都是可以控制速度快慢的。而且我也不会小回，更没有发言权了。

你就说你穿了什么J去的吧，要是黑衣黑裤丝袜罩头，干坏事的；要是吊带短裙丝袜罩腿，那就是找坏去了

I just want to express my view on the turning motion during short radius turns (srt)

The ski-turning-itself motion is a combination of pressure applied by skier to ground and the pressure from ground to skier. Note when I say pressure, it also means force, also vice versa. As the turn completes (ski moving from the far side of the body to under/in front of the body), the direction of force from ground to skier becomes longitudinal from lateral, w.r.t the skier. when a high pressure is applied evenly throughout the turn, which I believe we should do in srt, combing the body weight in motion at speed, and the force, pressure at foot greatly exceeds that is applied by the legs. In term, the leg are pushed back naturally, and the feet would return to its natural position (straight), and the pressure from ground would reduce to a point that is smaller than the leg application, allowing the leg to push back on the ground to extend outward again.
