Do rods affect lure action?

I’m still pretty new to using lures and I like to practice in my pool, I have two different rods of the same power (medium) however, one of them is a lot stiffer than the other. I noticed when using jerkbaits/twitchbaits on the flimsy rod, the action is a whole lot better. I’m just wondering if I am doing something different somehow. The stiffer rod is longer 7’6, while the other is 7’
