在今年選秀前,到湖人試訓,傳說跳出了歷史等級的48吋最大起跳度的Dennis Smith Jr.,過去幾天應該也沒多少人把這句話當真,頂多當成鄉野傳奇,搞不好是選前放的消息,抬抬自己身價,所以大家看看也就過了。不過好勝心強的DSJ在選秀結束,確定加入小牛之後,總算也願意自己揭密了。

 

 

媽阿!跨下360度!I am Dunk King!

 

今天早上視頻流出,媽阿!跨下接360度,OK,不要驚慌,去年Boston Celtics的新秀Jaylen Brown也幹過,咱門來複習一下。

OMG!Jaylen Brown for 360度跨下

 

根據體測數據:
Jaylen Brown  身高6-6.25   穿鞋6-7.5    翼展7-0    最大摸高8-7.5
Dennis Smith  身高6-2        穿鞋6-3       翼展6-3    最大摸高8-1

所以我們簡單的算,兩人站立的最大摸高差6吋。
Jaylen Brown 16-18歲的時候測試,他的最大跳躍高度約39.5到42吋之間。
所以用數據來做換算,39.5到42吋加上6吋,結果就是45.5吋到48吋之間。
看來DSJ這個48吋應該是確實的,而且比較起來,DSJ助跑的距離短上許多阿,真是嚇死人的爆發力。

 

至於DSJ之前經歷過的ACL手術,首先看一下下面這一段話:

As you read about ACL surgery you will see references to many different techniques.  Our thoughts about how to fix an ACL are changing.   Surgery to replace a torn torn ligament have evolved A LOT over the past 5-7 years.  Older methods did not place the ligament where nature intended it to be.  Many sports docs are very knowledgeable about these latest technique modifications.  This is an area of much interest.  You should feel open to talk with your surgeon about what type of reconstructive surgery they perform.

ACL手術確實在這5-7年之間突飛猛進,技術的進步不可同日而語,目前普遍使用的方式是類似於棒球的Tommy John手術,利用自體或異體的方式移植接近長度與寬度的韌帶過來做橋接。

 We need to use something to reconstruct your new ACL with during surgery.  See our video discussion below on graft choices.  We have two broad options:

1. Allograft – tissue from a cadaver, and

2. Autograft – tissue from your own body.

The literature surrounding the use of allografts, especially in young patients has demonstrated a failure rate approaching 40% in some series.  Bottom line, unless there is a strong reason why you can not use your own tissue (autograft) then you should probably not use allograft.

In the autograft category we have two main choices- a portion of your hamstring tendons, or the center of your patella tendon.   Both grafts work well and stand the test of time in a properly performed surgery.  A patella tendon graft certainly hurts more, but that may be worth it in certain individuals.  Research is starting to show that a hamstring harvest in women may not be a good thing for a high level athlete.  Women tend to be quadriceps dominant… so  the front of their thigh is stronger than the back where the hamstrings are.  It stands to reason that we do not want to make them even more quadriceps dominant by harvesting their hamstring tendons.   In some people, especially elite athletes, a hamstring graft can produce weakness.  While barely perceptible to most, some will notice the difference.  Over my career the pendulum has swung from patella tendon grafts to hamstrings and it appears to be swinging back once again to patella tendon grafts.  Have a long discussion with your physician.. question why they suggest a certain graft.  This is especially true if considering ACL surgery with an allograft.
