A propensity for forward rolled shoulders during the back squat may also be due to lifestyle-induced postural weaknesses (i.e., upper crossed syndrome, which results from consistently internally rotated shoulders leading to excessively shortened or tight pectorals).
> To perform the low-bar back squat, rest the barbell on the middle trapezius region with hands grasping the bar wider than shoulder-width apart. It is important to note adequate shoulder mobility (external rotation) is required to hold the bar securely.
Rotating the feet (e.g., neutral, 30–40° medial, 80° lateral rotation) while performing the squat, regardless of depth and stance width (75–140% shoulder width), has been shown to have no noticeable effect on leg muscle activity (rectus femoris, vastus medialis, vastus lateralis, adductor longus, semimembranosus, semitendinosus, and ...
6 paź 2018 · Research has shown that the posterior rotator cuff muscles (infraspinatus and teres minor) are most efficiently activated with the simple side-lying external rotation exercise. 1,2 These two muscles keep the humerus bone compressed and centered in the joint socket during arm movement (keeping the golf ball centered on the golf tee).
Since the gluteal muscles have a large role in both femoral external rotation and abduction, exercise selections that improve the strength and control from these powerful muscles groups will likely translate to the reduction of knee valgus during squatting. Suggested exercises include variants of the squat exercise that have a focus on ...
It was concluded that the Squatbar® induces similar kinetics, kinematics, and EMG when compared to the Olympic barbell, except for reducing external rotation of the shoulder.
The present results showed higher muscle activation for BF in the partial back squat when compared with full condition, which may be explained by the fact that it acts as a joint stabilizer at the knee and a prime mover at the hip.
