structural imbalances - Personal Trainer Community - Forum

Hi,
I was just wondering - john- perhaps you might have some data on this, as to relative muscle strength's and structural imbalances.
I have been reading alot of research from poliquin and chek as to using stuctural muscle imbalance graphs, but they don't provide much data as to the actual relevant info- ie back squat 1rm should be 160% of bench press. (this is a figure poliquin has supplied).
Does anyone have any list of the core compound movements and how they should relate to each other?
thanks
sam

maybe this can help a little bit

Muscle Groups Balance Ratio

Hip extensors and flexors
1:1
Elbow extensors and flexors
1:1
Trunk extensors and flexors
1:1
Ankle inverters and everters
1:1
Shoulder flexors and extensors
2:3
Knee extensors and flexors
3:2
Shoulder internal and external rotators
3:2
Plantar and dorsi flexors
3:1

R/L Difference <10-15%
Strength to body mass: Upper should be at least 40-60% of Lower

wesuhlee - Do you have a source for this information? I would like to learn more.

this was stuff i picked up this year from my exercise testing and prescription class...we use ACSMs Guidelines for Exercise Testing and Prescription small book...any good piece of literature or textbook that has to do with exercise testing and prescription will probably be a good source as well
