好多人成日都會爭論,究竟相撲式硬拉(Sumo Deadlift)係咪傳統硬拉(Conventional)嘅「作弊」版本呢?
.
答案:唔係。
.
雖然Sumo DL比起Conv. DL嘅動作幅度少咗大概20-25%,但咁唔等於拉Sumo就會容易過拉Conv.,兩者嘅動作set-up唔同,並唔可以咁樣一概而論。動作幅度雖然唔同,但係兩者平均都需要5-8秒拉起1RM。
.
而且,一般嚟講,用Sumo DL將重量拉離地面所需嘅時間都會多過Conv. DL,不過就比Conv. DL容易少少做到Lock-out嘅位置;而Conv. DL就恰巧相反。
.
講到兩者嘅拉法,set-up唔同,最大化地激活到嘅肌肉都會有分別。但係睇返EMG(Electromyography/肌電圖)嘅研究,兩者係拉起槓鈴時,肌肉發力嘅最大分別主要嚟講只有兩個:
.
膝關節彎矩係比Conv.嘅多於3倍,
1⃣Sumo DL:膝關節力矩係比Conv. DL嘅多於3倍,所以更加集中係四頭肌發力;
2️⃣Conv. DL:因為拉起重量嘅時候軀幹更加傾前,所以豎脊肌(Erector spinae, 脊柱兩側嘅肌肉)要發更多力,令背部伸展至lock-out位置;
而臀部同膕繩肌嘅發力程度都係差唔多。
.
其實就無話邊個拉法容易過邊個嘅,每個人嘅人體結構唔同、肌肉力量唔同,因人而異。
.
最好就當然將兩個拉法都放入program裡面,練返幾個月,感受下自己用邊個拉法會大力啲、舒服啲,之後揀返適合自己嘅方式訓練。同時間,你都會發現自己嘅弱項係邊到,而令到自己唔適合另一種拉法。

🔍Good morning與 Romanian deadlift (RDL) 大不同
兩個動作都係加強下身肌肉唔錯嘅動作,睇落去臀部嘅活動好似係一樣,兩個動作又係係運用緊膕繩肌同臀部肌肉,咁兩者又有咩分別呢?
.
1⃣技巧方面
Good morning係好似深蹲咁首先要將槓鈴放係上背,夾實肩胛骨支撐槓鈴。而RDL就要好似硬拉咁放係雙腳前方,雙手以膊頭闊度緊握槓鈴。
.
兩個動作一開始都係站立狀態,而無論係Good morning定RDL,都要運用hip hinge嘅技巧,將臀部推後,再盡量拉長hamstrings;上身前傾之後要回到站立姿勢,一樣係以臀部推前發力💥
.
2⃣肌肉參與
兩個動作其實都係集中強化身體後方肌肉群,包括🍑臀部、腰背肌(erector spinae)同hamstrings。你嘅核心都需要一定嘅穩定性,防止下背彎曲。
.
但係上一點提到,做Good morning槓鈴要放係上背,需要夾實肩胛骨以支撐槓鈴,所以依個動作比較可以將背部伸展嘅力量孤立,集中於強化背部後拱嘅力量,有助你深蹲或者硬拉,依類需要穩定背部力量嘅大複合動作。
.
同RDL相比,因為要用雙手握實槓鈴,所以全身所使用嘅部分力量會比咗前臂,相較無咁可能孤立背部嘅力量。
.
🌟兩個動作其實都有佢哋嘅重要性,如果你想加強背部力量,你可以嘗試做多啲Good morning;如果你想更加集中下肢、臀部嘅力量,你可以嘗試做多啲RDL。而最後嘅做法,當然係將兩個動作都分開日子咁加入去你嘅programme裡面啦😉

𝐁𝐢𝐫𝐝 𝐃𝐨𝐠 𝐢𝐬 𝐇𝐚𝐫𝐝! 𝐓𝐡𝐞 𝐌𝐜𝐆𝐢𝐥𝐥 𝐛𝐢𝐫𝐝 𝐝𝐨𝐠 𝐭𝐨 𝐛𝐞 𝐩𝐫𝐞𝐜𝐢𝐬𝐞.
I relearnt this move during Benjamin Siong Australian Strength Performance internship and dude it is hard!!!! Thanks for fixing my form George Menelaou !
I'm sure you've seen this many times and thought hey the move is easy. Far from it. When you do this correctly by flexing your lats, glutes and abs it gets seriously hard. This becomes an excellent move to promote a stable core while movement occurs at other joints - the arm and legs.
How to do it?
𝐒𝐭𝐞𝐩 𝟏:
Get into a table top / all 4s position with a neutral back. No arching or rounding of the back.
𝐒𝐭𝐞𝐩 𝟐:
Without any movement to happen at the low back, kick on leg backwards while raising the opposite arm. Make sure leg and arm are fully straight and they shouldn't be too high or too low. Make a fist which is in a neutral position (back of hand facing outwards) - not superman :) This will increase muscle activity of the core (especially erector spinae)
𝐒𝐭𝐞𝐩 𝟑:
Hold the position for 10 seconds on each side.
Give this ago, I know i'll be adding this a lot more to help me engage my abdominal which are probably not as awake as I'd like base on what George was saying.
Have fun bird-dogging correctly 🤗
