[Neto61]

wat is het verschil waneer je met een curlstang breed of kort pakt bij je je biceps training?

[talalelh15]

Verwaarloosbaar voor jou.

[Neto61]

ik bedoel crul

[talalelh15]

het antwoord blijft hetzelfde.

[Neto61]

het antwoord blijft hetzelfde.

verwaarloosbaar voor mij? for me? voor moi? voor neto61?

[talalelh15]

Yes, true story

[Neto61]

Yes, true story

why meee?

in de als ik het goed zeg anatomie van de belasting van de spier zou die kunnen uitmaken of je de binnenste op buitenste kop van de bicep bracialis aanspreekt.


echter zou ik je toch adviseren om er mee te wisselen want afwisseling is goed voor de spier

Dat dacht ik ook, binnenste en buitenste kop.

ik bedoel crul

Volgens mij bedoel je curl. Wat de greep betreft

The biceps brachii (bi'seps bra'ki-i)

The biceps is a biarticular or two-joint muscle. Simply meaning it is made of the shoulder and elbow joints. The biceps is considered to be the strongest of all the elbow flexors, especially in the supinated (palm up) position. With the palms in pronation (down) position, the effectiveness of the biceps is greatly diminished because of the disadvantageous pull of the muscle in this pronated position. In any case, pronated or supinated the same muscles are used to flex the arm.

While the biceps is only one muscle, it is made up of two distinct heads-- the long head and the short head. The long head originates at the supraglenoid tubercle which is located just under the collar bone and close to the shoulder joint. It inserts or attaches to the radius (small bone or top of the forearm) just about one inch below the elbow joint. The short head originates at the coracoid process of the scapula, which is just over the shoulder joint. It inserts at the same location as the as the long head.

The biceps are responsible for flexion of the elbow joint, supination of the forearm, and weak flexion and abductionof the shoulder joint.

Even though the two heads of the biceps are one muscle they both seem to have specific functions in flexion. Brown et al. (1993) using surface electromyograms (EMG) recorded from the long and short heads of biceps brachii, found that the long head produced more EMG activity at the beginning phase of the lift when the muscle was at it's longest.

Furthermore, it was found that the short head seemed to produce the most EMG activity at the top phase of the lift when the muscle was at it's shortest. While both heads are used to complete a full range of flexion, partial movements may be used either at the top or bottom of the lift to further stress the two heads of the biceps.

Now, because both the long head and the short head originate at the shoulder, rotation of the shoulder joint must have some effect on bicep training. So by changing the grip from wide to narrow we should be able to target different heads of the biceps. Right?

Well, we already know that the long head works best when it is fully stretched. So obviously by rotating the shoulder laterally, the long head is streched even more. Brown (1993) and Kapandji (1982) both agreed that when the shoulder is laterally rotated, activation of the long head of the bicep is indeed increased. Furthermore, the same researchers added that when the shoulder is rotated medially, activation of the short head of the bicep increased.

This simply means that a wider grip will hit the long head and a narrow grip will hit the short head.


Once again I would like to remind you that the biceps are strongest with the forearm supinated (palm up). So any curling type exercise done in this position, with a full range of movement would easily strengthen the biceps. Dumbbell curl, barbell curls, or cable curls would all be excellent exercises.

Ruw vertaald, handen wijder dan ellebogen is buitenkant, handen smaller dan ellebogen is binnenkant. Onderste deel van de ROM is buitenkant, bovenste deel van de ROM is binnenkant.

Verders komt bij mediale rotatie (handen smal) de pees van de lange kop geknelt te liggen in de biceptiale groeve waardoor de lange kop niet voldoende kan functioneren.



Dus

Handen wijd, ellebogen smal (laterale rotatie) accentueert de laterale kop.
Handen smal, ellebogen wijd (mediale rotatie) accentueert de mediale kop

Ik zelf pak altijd gewoon binneste bij bicep curls.. Buiten zou ff een ander deel van je bicep aanspreken maar vind het een verrotten oefening, pak ik liever een heel andere oefening voor.
