1. 關於慢頻率與手腳協調 (Slow tempo and syncing legs)
問：更慢的頻率是不是有利於手腳動作的協調？
Can slow tempo and stroke rate be a reason for syncing legs?
答：是，也不是。更慢的頻率，手腳協調確實更容易。但更快的頻率，同樣也可以達到。手腳配合的時機，不僅和頻率有關，和推進力也有關係。延遲打腿，你能獲得更大的推進力。
Shinji Takeuchi: Yes and no. It is easier to sync leg and hand movements at a slower tempo. But you can do it at a faster tempo, too. And the timing can be adjusted not in accordance to the tempo, but the degree of propulsion. As you delay
the timing, you can get more propulsion .
2. 關於水下前伸手臂與節能 (Extending arm underwater)
問：你看起來好像在水底往前伸展手臂。為什麼呢？是因為長距離能夠節省能量嗎？
You seem to stick your arm and then extend it underwater. Why is and does it save energy on long distances?
答：這樣，能加快划水。
Shinji Takeuchi: You can move the other hand underwater more quickly by doing so.
3. 二拍打水與六拍打水的比較 (2-beat vs 6-beat kick)
問：二拍打水比六拍打水好嗎？
My question: is 2 beat kick better than 6 beat kick?
答：對長距離游泳來說是的。
Shinji Takeuchi: For long distance swimming.
4. 浮力與打腿技巧的關係 (Buoyancy and kicking)
問：你看起來浮力很好，如果浮力不好的話，是不是要更多地打腿？
You seem to be a good floater besides being a great swimmer! Would I be right in thinking that if your natural buoyancy is low, then you would have to kick more?
答：百分之五十到七十的身體平衡能夠不通過打腿來提高。如果你身高超過180公分，BMI少於18，你可能需要提高你的打腿技巧。
Shinji Takeuchi: 50-70% of body balance can be improved without kicking. If you are taller than 180cm, and your BMI is less than 18, you might need to hone your kicking skill.
5. 划水頻率範圍 (Stroke rate ranges)
問：我發現你視頻中的划水頻率是1.4秒。你的其他的划水頻率是多少？如果找到最適合自己的頻率？
I can see you are at about 1.40 sec/stroke on the video... What are your range of stroke rates... How do you find the best stroke rate?
答：
1.15秒：基本頻率 (Base tempo)
1.00-1.30秒：頻率金字塔練習 (Tempo pyramid practice)
1.00秒：比賽頻率 (Race tempo)
Shinji Takeuchi:
1.15: base tempo
1.00-1.30: for tempo pyramid practice
1.00: race tempo
6. 單側呼吸與肩膀受傷的解決辦法 (One-side breathing and shoulder injury)
問：我是左撇子，只在一側呼吸，這樣導致我的右肩受傷。我想知道除了雙側呼吸之外有其它的解決辦法嗎？
I am left handed ... and I tend to breathe only on one side which leads to right shoulder injury ... any solution to that other than bilateral swimming?
答：也許是移臂的問題，而不是呼吸的問題。在鏡子前試一試，看在移臂的初始階段，你能不能看到你的肘部。
Shinji Takeuchi: There may be a problem in recovery rather than breathing. Check if you can see your elbow at the initial phase of recovery when you stand in front of the mirror.
7. 維持流暢自由式的最低頻率 (Minimum tempo rate)
問：維持流暢自由式的最低頻率是多少？
...what must be the minimum tempo rate to maintain the smoothness of the TI swim?
答：我沒有使用節拍器，但是我覺得是1.4秒。
Shinji Takeuchi: I did not use the tempo trainer, but it looks 1.40 seconds.
8. 抓水與推水階段的技巧 (Catch and pull phase)
問：你是如何划水的，是只用肩膀的力量還是其它？
How do you pull? With shoulder only? Entire hand power? Or something else?
答：
抓水階段：身體前傾，讓前臂垂直於水面。
推水階段：讓手臂動作，跟隨身體轉動。
Shinji Takeuchi:
Catch and pull phase: Leaning forward while positioning the forearm vertical to the surface.
Push phase: Synchronizing the hand movement with the body rotation.
9. 腿部下沉的解決方法 (Legs sinking issue)
問：我的腿老是下沉，有的人說是要頭部朝下，有的人說要用上背部和髖部的肌肉。我想問一下你有沒有什麼好辦法。
...my legs are not parallel to the surface. They are around 10 inches down... Can you please share your knowledge?
答：如果你的BMI少於18，那麼你需要練習有效的打腿。如果不是的話，那麼有很多其它的方法來幫你的腿部上浮。
Shinji Takeuchi: If your BMI is less than 18, you need to practice efficient kicking. If not, many factors can raise your legs.
