Don't forget the ass muscle during those "high pucker factor" trad leads.

S-
Sweet idea, I'm psyched to see that people are doing some basic research on climbing topics, god knows that it's needed.
I'm thinking that you may run into some problems w/ this topic, or at least with the current breadth of the question. I'm not sure that it's specific enough to get a clear answer from. Which MM are going to take the lions share of the work is going to vary depending on the angle of the climbing terrain and how the holds dictate body position. It may be easier to look at which muscles are the prime players in a given body position or movement.
In a global sense I would say that the most important muscles in climbing are
Forearm: Flex Digitorum (profundus and Super.) and Brachioradialis
Arm: Brachialis and Coracobrachialis
Core: Rectus Ab, Transversus and the spinal erectors
Legs: Glut Max & Min and Hamstrings
Good luck w/ the proj and I would be super psyched to see what you find out.
cheers, BA

You might start with which muscles aren't that important.... Beyond the obvious ones, there are a so many that are crucial.

What about the back muscles for example the rhomboids and latimus dorsi. Forearms and legs are important, but I would imagine the muscles that retract your shoulder blades would play a major role.

This is a very far-reaching project.
I'd like to see an analyisis of co-contraction between flexor dig. profundus and extensor carpi ulnaris for hand/wrist,
comparison of brachialis vs. biceps brachii vs. brachioradialis for elbow flexion,
comparison between lat. dorsi and teres major for shoulder extension/adduction,
comaprison between rhomboids and middle trapezius for scapular retraction.
For the core, I think you'll be surprised at how much firing of the lumbar extensors you'll see.
In the lower extremties, You'll see lots of action in the adductors. Adductor magnus, as the name suggests, is a really massive muscle.
Please remember to post your progress and results. I'll help where i can.
To the moderators: These anatomy diagrams should be but into a sticky, or the dead horse graveyard.

Huh? Tendons certainly get stronger with use. Ligaments probably do as well.

Developed and conditioned, All the muscles are important, and more important is their balance. To much of one will put stress on another. In the long run injuries will occur if the balance is to disproportionate.

right, all the muscles are important, but I think the emphasis is on which ones get the most use/pull the most weight (no pun intended) while climbing.

Ligaments probably do as well. In reply to: Since a tendon is a living tissue, it is not a surprise that tendon shows the capacity to adapt its structure and mechanical properties to the functional demands of the entire muscle-tendon unit. However, compared with muscle, the experimental knowledge of the effects of strength or endurance-type training on tendon tissue is scarce http://www3.interscience.wiley.com/journal/119174515/abstract?CRETRY=1&SRETRY=0
How does that paragraph right there relate at all to the blatantly wrong post you made...
Tendons do indeed increase in strength, but obviously at a much slower rate than muscle tissue.

A weak effort for a "Science Guy"...a Scandinavian Journal is pretty obscure, the cited article appears to just be a review and it's almost 15 years old (ancient history), and you left out the last sentence of the abstract that refutes your claim: "The adaptive responses of tendons to training are therefore also slower than those in muscles, but they may finally be considerable if the time frame is long enough (3, 4)."

In reply to: Essentially, I would just like to focus on the smooth muscles rather than the skeletal muscles.
I think the most important smooth muscle in climbing is that found in the bladder.
I also think the use of the name 'scienceguy' is the definition of irony.

Bingo. And you beat me to it.

Dude, I made an earnest effort at helping. If you are a troll, then this is very well played, complete with excellent cheesetitting.
If you are not a troll,please look up the definitions of smooth muscle, and skeletal muscle.
Aside from posting Dr. Netter's excellent drawings, your "project" would thus far fail an 8th grade science fair.
