I don't know about the jogging bit - I know next to nothing about running. I'm guessing that you've probably optimized your body for a certain rhythm of pulses (your legs pump blood when they contract).

A related trick (cadence and heart rate) - at the top of climbs, you'll often find yourself blowing up just as you crest. You think "ah, I timed my effort right." Right? I don't think so. You blew up because your cadence increased, and even though your workload decreased, your heart rate went up (this is where my theory on cadence v heart rate comes in play).

Instead of staying in the same gear, shift up aggressively as you crest a climb with the goal being keeping the same cadence. You'll find your heart rate doesn't skyrocket.

However, just like you need to keep a lower HP engine kind of wound up, your legs need a certain level of cadence so you can respond to efforts (whether it be to make a light or to respond to an attack). If you keep your climbing cadence over the top of the climb, and it's typically lower than your normal cadence, then you'll be hard pressed to accelerate briskly.
