Factors are based on:
Muscle? “A”- Strength referring to the ability to exert a force on an external object?
e.g. lifting a weight.
Muscle? “B”- Strength referring to the force exerted by the muscle itself?
e.g. on the place where it inserts into a bone.
Muscle? “C”-Strength of muscle based on its weight?
e.g. pound for pound strength.
I guess it would depend upon what type of strength we are referring to.
Is one referring to strength endurance or 1RM strength or somewhere in between? Should one take into consideration the type of muscle fiber of the muscle one considers to be the strongest? Can cardiac muscle which is involuntary and skeletal muscle really be compared as far as strength is concerned?
Is one forgetting that skeletal muscle do not work in isolation.
Having said the above. My answer is I don’t know.
