Ik heb wel eens gehoord dat je biceps uit 2 verschillende spieren bestaan. Een spier aan de binnenkant en spier aan de buitenkant. En dat je deze spieren afzonderlijk kan trainen, waardoor je biceps meer kan trainen op de piek of breedte. Klopt dit en zo ja met welke oefeningen kan dit ?

    Mwah moet weer even diep graven, dacht dat hetongeveer zo was, beide koppen worden aangesproken door elleboogflexie, ofwel een curl beweging, meen echter dat het zo was dat er meer activiteit in de korte kop is als je deze vanuit je schouder aanspreekt, dus incline curls of spidercurls.
     
    Goeie genade dan heb je ook nog dat draai stukje spierdinges geval waardoor je ook de bicepspiek kan beinvloeden. Pffffffff weet je ben het gewoon kwijt.

        Daar staat al zoveel over geschreven in ons archief dat een simpele search op het woordje biceps genoeg resultaten opleverd.

            De brachialis loopt over je elleboog heen en de biceps brachii zit in je bovenarm. Die laatste zit zo'n beetje van de voorkant van je schouderblad tot aan je spaakben. Met z'n allen zorgen ze voor het buigen en voorwaarts heffen van de arm, en het supineren van de onderarm.
             
            Persoonlijk maak ik me nooit druk over piek of breedte, ik train 'm gewoon in compounds en zo nu en dan geisoleerd. Dus hoe je speciaal de piek kunt trainen kan ik je niet zeggen. Heb het idee dat het meer genetisch bepaald is of je een bolletje of een langere glooiing hebt.

              Ja ja anatomiewonder, die piek is harstikke belangrijk natuurlijk dat is hetzelfde als het hebben van een grote euh auto. Piek moet als je tenminste al armen hebt van minstens 50 cm, ik moet dus nog een flierpje met 49 en een bietje dus ik wil nu ook een piek wel graag deze vraag serieus beantwoorden ja.

                Oh dan wil ik er in dat kader nog wel aan toevoegen dat de belangrijkste functie van de biceps is: een drankje naar je mond brengen maf!
                 
                Mannending denk ik, die biceps blij by the way, de boel zit zo verstrengeld dat de delen IMO niet echt afzonderlijk te trainen zijn.

                  Nou ja dat bedoelde ik in mijn eerste post ook te zeggen, 1 oefening waarbij je de bicpes meer aanspreekt vanuit de elleboog en een ander vanuit de schouder zou de truc aardig moeten doen, piek is genetisch volgens mij, maar toch was er iets met dat indraaien naar de schouder toe, van neutraal naar supinated, maar weet het niet goed meer.

                      Oh en Sisjuh, ik was nog een vracht smiley's vergeten, of in elk geval dat werkt nog niet goed bij mij.
                       
                      En Sheru, optrekken als in supinated dan, want bij een wijdere grip en pronated doen de triceps meer mee geloof ik dan de biceps en eigenlijk voel ik dat ook wel.

                        Oh, ik doe dat nooit, want dat trekt m'n elleboog niet of nauwelijks, en tóch is 't voor 't eerst dat m'n biceps echt doen wat je zou denken van tillen: groeien.

                          Hey.. chinnen is ook bij mij de oefening waarvan ik denk "daar doen die biceps maar leuk aan mee als ze zonodig willen". Doe ze juist meestal smal, breed voelt minder prettig aan.

                            Building Those Big Guns

                            Tom McCullough MEd., MSS 


                             

                            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 of 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.
                             
                            (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)
                             
                            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.

                            The brachioradialis (bra'ki-o-ra'di-a'lis)

                            The next muscle involved in flexion of the arm is the brachioradialis. The brachioradialis originates at the lower two-thirds or the humerous (upper arm) and inserts on the radius, just above the thumb and wrist. This muscle is not only responsible for flexion of the arm, but it also prontates the forearm from a supinated position to a more neutral position and also supinates the forearm from a pronated position to the neutral position. The brachioradialis acts best as a flexor or the arm when the forearm is in the mid or neutral position between pronation and supination.
                            Therefore, the brachioradialis is best targeted by performing curls with the forearm is in a neutral position. Dumbbell hammer curls with a full range of movement, not only strengthen the biceps, but really blast the brachioradialis. Just remember that the key is keeping the forearm in a neutral position.

                            The brachialis (bra'ki-a'lis)

                            The brachialis muscle is used in combination with the other elbow flexors everytime elbow flexion is performed. However, this muscle is the only elbow muscle that is only responsible for flexion. The brachialis originates on the top portion of the humerous under the biceps. It inserts on the ulna (large bone of the forearm) just past the bend of the arm. The brachialis performs flexion by contracting and pulling on the ulna.
                            The brachialis is used any time the arm flexes, however when the forearm is in the pronated (palm down) position, the biceps are less effective and the brachialis has to do much more of the work. Therefore, by doing any type of curling exercise with the forearm in a pronated position, the brachialis will be stressed even more.

                            The pronator teres (pro-na'tor te'rez)

                            The pronator teres muscle is mainly used to pronate the forearm. However, it also functions as an elbow flexor by assisting the biceps and brachialis in movement of the arm. The pronator teres originates at inside of the lower part of the arm and attaches to the upper part of the radius.
                            The best exercise to hit the pronator teres is any exercise that would add resistance to the action of forearm pronation and supination. A small dumbbell or large hammer can be held while you twist the forearm from the palm down position to the palm up position and back.
                            While all of the many different exercises and angles of attack may not really be necessary to build those big guns, a few slight variations in grip width, range of motion, and palm position may be just what it takes to really make those arms to grow.

                                sis


                                Hey.. chinnen is ook bij mij de oefening waarvan ik denk "daar doen die biceps maar leuk aan mee als ze zonodig willen". Doe ze juist meestal smal, breed voelt minder prettig aan. 

                                Ik doe wel smal, maar niet gesupineerd. 

                                You 's So high 'n mighty with all your muscle. Go ahead boy, pick up that barbell and show me what you can do.
