If you're extremely out of shape or are doing it unnecessarily, it will tire you out quite quickly. However, that isn't who will be using the strategy. A win by attrition requires ample resources by its very definition.
Right... but the OP stipulates that the combatants are equal size, skill, ability, in shape, etc... so the other person can last just as long as you can.
And either way, that's a pretty silly strategy. You can just back up to maintain your range advantage. Jumping throws you off balance and is easy to time, as are repeated back-and-forth swings. For the bat person to have a chance he has to either time his strikes as a counter to the charge of the knife person and get out of the way quickly, but on a quick reaction basis, not a constant-motion basis.
