Tension increases as the concentric lifting speed increases as well though.

Yes, a U-shaped graph would be how it would pan out.

1. If you watch most people in the gym train, lifting speed is pretty much constant...about a 1-2 second eccentric...a pause of zero to one second...and a concenctric of X to 1 second.

2. I agree that studies should be done using a few different "reasonable" lifting speeds and results compared.

3. I am more concerned with results regarding areas of the muscle showing the most activity.

You mean like upper/lower, etc?

Upper/Lower
Short Head/Long Head
Inner/Outer
Anterior/Lateral/Posterior

Depends on the muscle.

Dale leave Gp alone. I won't stand for you harassing him.

**Dale Mabry** · 01-02-2006, 02:47 PM

I wasn't harassing him, I believe that you can activate the sternal and clavicular heads of the pec major separately. It is at least physiologically possible, whether it happens remains to be seen.

**topolo** · 01-02-2006, 04:53 PM

One could theorize that it is physiologically possible but I know of no evidence to support the conclusion that the heads can be activated separately.

**Dale Mabry** · 01-02-2006, 05:05 PM

Is there evidence that it does not happen?

**topolo** · 01-02-2006, 07:42 PM

Yes, but it is a secret.......you have to be a mason.

The best evidence is empirical.

Not really GP, eyewitness testimony is notoriously unreliable. Having said that, if you say it is true........I believe you!

Well, there is a slight difference between eyewitness testimony of an event, and the visual data collected over 15 years of observation

As I said earlier......if you say it, I believe it.

Well, thank you for the confidence you have in me my friend!
