Sentences with word «pectoralis»

Horizontal adduction (drawing the arm across the body) is the only movement that involves the entire pectoralis major, but when you're holding a barbell you're locked into a limited amount of horizontal adduction, which means that your upper arm is limited in how much it can move towards the midline of your body.

Therefore, the data appears to indicate that bench angles between 30 and 56 degrees display superior pectoralis major clavicular head muscle activity than steeper or less inclined variations.

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

Bench press technique insofar as it relates to scapula position, lower back arch or glenohumeral angle, as well as weight implement used, does not affect pectoralis major muscle activity.

Pectoralis minor is the smaller sibling of the larger and more talked about pectoralis (pec) major.

To reduce the risk of pectoralis injuries, the surgeons urged the military to ban maximum - weight bench press competitions.

For example, the surgeons had to send pectoralis tear patients to foreign local hospitals for MRIs.

Since the front deltoids are a very small muscle compared to the huge pectoralis major of the chest, it stands to reason that during the bench press the deltoids of your shoulders will fatigue way before your chest even starts to get a proper workout.

The big culprit for shoulder pain is often pectoralis minor.

There are 4 rotator cuff muscles, and only one of them turns the shoulder inwards (the subscapularis), but there are other big muscles [pectoralis major (pecs), latissimus dorsi (lats), teres major] that are not part of the rotator cuff that help to turn the shoulder inwards.

Because the fibers of the front deltoid originate alongside the fibers of the upper pectoralis major, the two muscles act like conjoined twins on chest presses.

The chest muscles (mainly m. pectoralis major are underneath the boobs, not part of them, and as spot reduction (meaning fat loss from a targeted area of the body) is impossible, you're not gonna lose your boobs by bench pressing.

The pre-exhaustion method might not be an effective technique to increase the extent of neuromuscular recruitment for larger muscle groups (e.g. pectoralis major for the bench press) when preceded by a single - joint movement (e.g. pec - deck fly).

They reported no difference in peak pectoralis major muscle activity.

More specifically, the barbell bench press and machine bench press produce equal pectoralis major EMG amplitudes with relative loads between 60 — 90 % of 1RM (McCaw et al. 1994, Schick et al. 2010, Saeterbakken et al. 2011).

However, while many single - joint exercises produce comparable pectoralis major EMG amplitude to compound exercises, multi-joint exercises also produce greater involvement in other muscles, such as the triceps brachii and the anterior deltoid.

However, they do not improve pectoralis major EMG amplitudes and during multiple repetition sets have negative effects on strength and consequently, muscle activation.

Narrower grips widths of between 100 % and 200 % of shoulder width may enhance pectoralis major clavicular head activity.

However, all three studies did not normalize the EMG measure to maximal pectoralis EMG amplitude, which makes a real comparison difficult.

Including both variations may be optimal for complete pectoralis major development.

For example, relative EMG amplitudes during an unstable push up range between 5 — 10 % greater than their stable surface counterparts, which usually produce around 30 % of relative pectoralis major EMG amplitude.
