1．因為我知道你會把問題焦點放在跳起這一個動作，所以我才會測試自已在一次跳躍可以收縮幾次，做完整伸縮只夠做一次，做三回次我也沒拍出來自己看一下，不過跟完整的不太一樣，動作較小，但一樣有伸縮動作。我考慮考慮要不要拍，有點累，滑雪都不需要花這麼多力氣。
2．你們把我的重點放錯地方了，我之所以剪這樣一段，就是說，在我全身拉直時，剛好碰撞饅頭就開始做收腳的動作，看來我得重新剪一段動作以符合我那空中收縮的重疊位置。
3．我不是說過，我做的是全身伸縮，以腹腰為軸心，我不是放M．H的健身房收腳的影片嗎，幾乎一樣的方式，只是我再多用上了上腹肌那部份。
4．這是我一個推測，得上大雪場多滑幾天才能確定是不是，但這樣應該是個理想狀態。
5．能做到一跳三回次伸縮不算證明嗎？
6．超過時，就是會起撞起引起有點失去平衡，如膝撞胸後的失衡，在空中就要做第二次極短的伸縮動作回復基準平衡就好了。
所以我提出我可以跳一次伸縮三次，代表我確實可以不需要靠外力就能做伸縮動作了。
PS．其他人就不回覆了，自己看這篇說明就可以了。
1) Good job in showing us that your could extend/retract your legs. But you didn't show as your leg retraction could reduce pressure. Isn't that you ask us to show? You ask us to proof why "leg retraction" could "reduce pressure". Where's your proof?
2) Again, where is your proof? What's the pressure value? You didn't answer me.
3) "以腹腰為軸心" and once you retracted your legs, you will need to extend it, which is the same as "還要伸展時太花時間了". Why your way of leg retraction is better than other?
It is correct to "以腹腰為軸心", but your reasoning is so wrong.
4) Maybe one day you will learn more.
5) Again "一跳N回次伸縮" can't proof "收縮釋壓". It can proof that you could ""收縮", it can't proof anything with "釋壓".
6) But you said it is tiring to do the 2nd retraction. So how could you ski down a big mogul field without tiring where you can't always absorb enough. And when you comment PKU that he has to retract his legs after going off a mogul, what you think he is doing at that time? Is he also retracting to regain his pose and balance? What do you think?

Yesterday at the supermarket, I saw a baby and he could also 不需要靠外力就能做伸縮動作 while he was laying down on his back. Later on, his parents picked him up in the air, I also saw the baby 不需要靠外力就能做伸縮動作. Does this baby know how to "收縮釋壓"??
