I'm hoping we can perhaps avoid discussion of legs/quads because this really wasn't what I intended for it to focus on. While it's true that leaning on a bench would help to reduce leg momentum, I was thinking moreso of the shift in active lifting angle.
I would really love is to have some EMG analysis reading's on what is happening with the lower body, particularly the glutes, hams & quads, when performing them for reps & held isometrically.
I imagine some light activity due to stabilizing. Much like there is in the lower back to stop from falling forward. If it's too high compared to max output, somebody's got some weak legs.
Would I be right in saying that performing standing barbell front raises (isometrically) with straight legs & no knee band, there wouldn't be any chance of quadricep involvement?.
I imagine if the knees are locked it'd be hard to cheat weight up with quads. Probably some light activity in them assuming you're not hyperextending the knee, but shouldn't be anything significant.
You're too new here to know which trolls to feed and which to ignore.
Trolling requires lying to get negative reactions. I'm stating genuine curiosities in hopes to get positive ones from those who share the interest. I regret if you are skeptical of my truthful interest in this field of study. If you are not and are simply calling me a troll to upset me when you recognize my honesty, then that would mean you would be the one trolling ;)
