Sentences with phrase «horizontal flexion»

The researchers this time compared a number of exercises that utilised the upper - body weight as leverage including static inverted row, L - sit, trunk extension (static horizontal back extension), static lateral flexion of the trunk (static horizontal flexion).

Shoulder horizontal adduction (also called shoulder horizontal flexion) involves bringing the arms together in front of the body at shoulder height, as shown in the picture below.

The bench press grip width appears to affect peak shoulder abduction and horizontal flexion angles that correspond to key regions in the bench press, such as the sticking region.

Indeed, the pectoralis major has longer moment arm lengths for shoulder horizontal adduction (also called shoulder horizontal flexion) than any of the other chest muscles, indicating it is the prime mover for this action (Keuchle et al. 1997).

As the shoulder moves in horizontal flexion from 0 degrees (with the arms reaching out sideways from the body), the moment arm length increases from approximately 32 mm to 46 mm at 45 degrees.

In general, it seems that compound exercises that include shoulder horizontal flexion feature as the best exercises for creating overall pectoralis major activity.

Keuchle et al. (1997) showed that the pectoralis major moment arm peaked at 45 degrees of shoulder horizontal flexion while the smallest moment arm was found at 140 degrees (reaching across the body).

Upper body pressing exercises typically include elbow extension in addition to horizontal flexion — i.e. bench pressing — or shoulder flexion — i.e. shoulder pressing.

Horizontal flexion.

Follow the movements shown in the videos; flexion, lateral rotation, medial rotation, abduction and horizontal flexion / extension.

As a whole (all heads working together), the pectoralis major assists adduction (lowering upper arm from side raise position to the midline of the body), medial rotation (rotating upper arm forward or inward to the midline of the body) and horizontal flexion (moving the upper arm from a side raise position to the front of the body).

The majority of studies seem to support the claim that the dumbbell bench press is a better option for anyone looking to increase his chest size, mainly because of the greater range of motion involved — a greater range of motion on pressing movements means more horizontal flexion and adduction and a greater recruitment of chest muscle fibers.

Not exact matches

Being close to the deltoid muscle, the clavicular head significantly contributes to flexion, horizontal adduction and inward rotation of the humerus, and is best engaged with exercises which involve shoulder flexion and movements that end with your elbows above your clavicle.

This is because all horizontal and vertical pressing exercises involve extension of the elbow (the primary function of the triceps) while all horizontal and vertical pulling exercises involve flexion of the elbow (the primary function of the biceps).

And if performed regularly and correctly, this rowing variation with horizontal band resistance can provide several unique benefits such as teaching you proper hip - hinging mechanics, improving balance, eliminating spinal flexion and forcing your lats to give their 100 % by both protracting and elevating them.

The function of the lats include extension, adduction, horizontal adduction, flexion, and internal rotation of the shoulder joint.

Assessing the effect of foot placement, Escamilla et al. (2001) compared the horizontal leg press performed with a high foot placement (90 — 100 degrees of knee flexion in bottom position) and a low foot placement (20 cm lower).

The middle trapezius is highly activity during retraction exercises, while the lower trapezius is highly activity in abduction / flexion exercises with the arm at or above horizontal, as well as horizontal rowing.

Da Silva et al. (2009a) investigated the effects of pelvic stabilization and degree of hip flexion on hamstring EMG amplitude during horizontal back extensions.

Therefore, the superior performance of the flat bench press over the incline bench press for the sternocostal head is probably because there is a greater horizontal shoulder adduction moment in the flat and decline variations, but a larger shoulder flexion moment in the incline variations.

Key shoulder movements that involve the pectoralis major include shoulder horizontal adduction (moving the arms together in the transverse plane at shoulder height), shoulder adduction (moving the arms down to the sides, from shoulder height), shoulder scapular flexion or extension (moving the arms to or from shoulder height in the scapular plane in front of the body), and shoulder flexion or extension (moving the arms to or from shoulder height in front of the body).

Gomo & Van den Tillaar (2015) further reported that the bench press performed with a narrow grip displayed significantly more horizontal shoulder flexion (arms further in front) compared to the middle and wide grip width at the start of the upward motion, point at minimum velocity and maximum velocity.

In addition, anterior delt will also pull the shoulder forwards (flexion), turn the shoulder inwards (internal rotation), and pull the shoulder across the chest (horizontal adduction).

Keuchle et al. (1997) reported the change in moment arm length from 100 degrees of flexion (arms slightly above horizontal) to 40 degrees (arms pointing down) showed a gradual increase.

The superior fibers of the latissimus dorsi displayed a peak moment arm length of 22.1 mm at 45 degrees of shoulder flexion (midway below horizontal) and a minimum moment arm length of -0.1 mm at 120 degrees (arms above the head).

This may imply that exercises with peak contractions at different points in the total shoulder flexion range of motion (both with arms at the horizontal and with arms close to the sides) are necessary in order to work all muscle fibers to a similar extent.
