Casting in a near vertical rod plane is it possible to create rotation without using the wrist?

Buy bending at the waist (rocking) , locking wrist then lifting (rotating) elbow?

I'd also have to say yes. My longer backcast is mostly performed with the rod-butt tucked against my forearm. The wrist really only comes into play after I've made the stop and I let the rod get out of the way of the oncoming line.

Most of the rotation in that back cast comes from rotating the elbow in the axis of the humerus.

Cheers,

I can see what you describe. I do the same...Suttle ways we create rotation besides using our wrist.
Thanks

Yes but it’s difficult to delay rotation without using the wrist and you need to change how you grip the rod (cradle/finger grip).

Not really adding more body movement, compensating instead with arm movement (esp. into last half or so of stroke) and to a very limited degree, some finger movement (you can see the grip I was using in that shot). Don't know technically if my finger movement was timed well enough to really matter, but at least I tried. Finger motion-capture next time! :p

Of course, in order to get from A to B with my casting stroke, the rod has to rotate (turn over). It's the degree of rotation normally added via wrist that has to be tweaked with alternate compensation.

I found that shorter range casting actually required more focus to replace the lost wrist movement. Not all that surprising, but it was interesting to feel it in action. By using the fiberglass cast, the distraction of trying to lock my wrist manually was removed, which allowed other sensations to be perhaps more obvious (again, hardly a technical analysis, but seat-of-the-pants feedback is still useful).

And if anyone is wondering, no, I did not break (as in "ouch!") my wrist. Just a cast set up to remove the wrist from the equation. Set up time was long enough that I could mold it a bit with my favored grip and get the rod into a good spot.

FWIW, the motion-capture session that photo was from helped to produce this little document:

That's interesting Jason. I see one of their findings was:

"Those who fished 10 days/year or less were more likely to have a wrist velocity much higher than shoulder or elbow velocities and those who were more experienced (i.e. fishing guides) had a much higher shoulder velocity."
