Hey Joe,

i have kinda a nerd question. The following just doesnt get into my head which i’ll try to explain via the comparison of cable work for triceps Vs. Swissbar/Dips Press for Triceps:

Cable Triceps: the maximum tension on the muscle is when the cable is perpendicular to the forarm and therefore the most far away from the elbow joint. The tension on the muscle decreases the further u get into contraction, since the cable is moving closer to the joint (moment arm and therefore torque decreases.. which u explained so well already). This fits the strength profile of the muscle – it gets weaker the more its shortened/in contraction.

Now.. Swissbar Press/ Dips: The chains or bands help that it gets harder as more as you get into the shortened position / into contraction, since, due to the reduced moment arms (elbow & shoulder) the torque decreases, and one can put more loads onto the muscles just like on the triceps in this example.

 

So, sorry for repeating but i hope i can explain it alright: one (-cable-) due to the decreased torque in the elbow joint the work for the muscle -decreases- (as it fits the strength profile of the muscle) going into its shortened contraction, and the other (swiss bar press / dips), the work for the muscle -increases- coming into its shortened position due to the usage of chains/bands (which now also kinda fits the strength profile of the muscle?).

The answer might be obvious and im just sitting on my own stupid head. I apologize then. But it just doesnt get into my brain.

 

(I’m new here and looking forward to be sucking on ur brain like a newborn at its mamas breasts.)
