LMAO, aight ok everything you said was pure bull even your rubber band explanation supported my view move the arm to the back on you little rubber band model and it will stretch showing that the muscle can be used to push from the bottom of the lift. But I'll tell you what you go on thinking that the hams move eccentrically on squats and thats why they are sore when ever they are really fuctioning as hip flexors to cause the soreness and go on thinking that lats only have one function. it won't hurt me any if you live in ignorance.
you make yourself look stupid. the 5 other trainers i talked to today....laughed at your responses. 2 of which have masters degrees in exercise phys. hmmm....
do you truly understand the words you are saying? eccentric? flexor?
just to actually HELP you:
taken from exrx.net (since you think im so fond of internet research)
-------------------------------
Concentric
The contraction of a muscle resulting in its shortening.
Eccentric
The contraction of a muscle during its lengthening. (in a squat, the knee is extending, ie...the hamstrings are LENGTHENING. In a bench press....the lats are LENGTHENING.
---------------------------------
Hip
Flexion
Bending the joint resulting in a decrease of angle; moving the thigh or top of the pelvis forward.
Iliopsoas
Tensor fasciae latae
Rectus femoris
Sartorius
Adductor longus
Adductor brevis
Pectineus
-----------------------------------
Extension
Straightening the joint resulting in an increase of angle; moving the thigh or top of the pelvis backward.
Gluteus maximus
Semitendiunosus
Semimembranosus
Biceps femoris (long head)
Adductor magnus (ischial fibers)
-----------------------------------
Latissimus Dorsi
Origin
Ilium
Posterior Crest
Sacrum (Posterior)
Vertebral Column (Lateral Surface)
Lumbar Vetebrae (L1-5)
Thoracic Vetebrae (T7-12)
Ribs (Posterior)
Lower 3 or 4 ribs
Insertion
Humerus (Proximal Anterior/Medial)
Intertubercular Groove (Medial Side)
my rubber band analogy is wrong?
LOL!
i cant spell it out any more clearly for you, i think now you are just messing with me but whatever. read a book kiddo or give me some references and ill believe you and go back and tell all of the great "mistake" that the world is making with regards to muscle contraction theories since cross bridges found a way to push instead of pull.
bwaaaahahahahaha!
