【主動不足(active insufficiency)】
.
當肌肉長度在「過度縮短」的位置,會使肌肉能「主動出的力減少」,這樣的現象我們稱為主動不足(active insufficiency)。因為肌肉的收縮,是倚賴肌凝蛋白(myosin)跟肌動蛋白(actin)的結合,我們稱為橫橋(cross bridge),橫橋(結合)的數目越多,能產生的力越大。當肌肉處在過短的位置,會使肌凝蛋白跟肌動蛋白彼此蓋住,所以形成的橫橋會較少。
.
這也是為什麼,許多動作跟姿勢,肌肉會處在相對「中間」的位置,稱為肌肉的休息長度(muscle resting length),既不是縮短、也不是拉長,因為能形成的橫橋是最多的。
.
🔸 生活的應用
因此大多數人,提著重物時,手肘會不自覺地彎曲到90度、呈一個直角,因為這是肱二頭肌(biceps brachii)的休息長度,能主動產生的力最大。
.
🔸 訓練的應用
訓練中,「同一個動作下,可能用許多肌群」,如果想要著重在其中一個肌群,可以將其他肌群擺在較短的位置,來減少他們的使用。例如橋式(Bridging)可以同時用到臀部跟大腿後側肌群,若傾向用更多臀部肌群,會透過增加膝關節的彎曲角度,使大腿後側肌群處在較短的位置,來達到主動不足。

This is a booty keeper!
Humpday sharing. A full leg workout to fire the glutes and using only bodyweight! Yeap and this is a follow along on my YouTube.
It's done EMOM style. In 1 minute complete the reps but with good form. The Tempo /rhythm of each rep is up to you. Go faster you have more rest time, go slower less rest time but I believe you would have better control on the movements. Remember form quality is key even with many reps 😉 You can also choose to drop it to half first.
Work 1 minute each exercise.

A1 30 squats
