基礎編
ピッチング動作解析の第一人者である川村監督は、球速を順調に高めていくためには、「ピッチングの土台となる合理的な体の使い方を早い段階でマスターする必要がある」と言います。
合理的な体の使い方とは、肩甲骨や股関節を「投げるためだけに使える状態」のことです。
たとえば、「猫背」になっている選手の場合、その時点で合理的な体の使い方はできなくなります。
なぜなら、猫背の姿勢は、肩甲骨がロックされている状態になり、投球のためではなく、姿勢をキープするために使われてしまうため、滑らかに動かすことができません。
その結果、ピッチングにはどう影響するでしょうか?肩甲骨が滑らかに動かせないので、ボールを投げるときの動作は、力任せに腕を振り下ろすような動きになります。
これでは当然、全身の力がボールに伝わらないので、速いボールを投げることはできません。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:

3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4.

Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence.
