I remember using a good treadmill protocol once in a lab, but it only gave you anaerobic capacity, not peak power output.
Any time I’ve done a Wingate, we’ve used a Monarch bike, hooked up to either a computer or some kind of counter.
To do something like a wingate on a regular bike, you would need to have an accurate measure of how much resistance you are getting on the bike, plus an accurate count of how many revolutions you’re getting in each 5 second span.
I guess if you could find some kind of temporary counting device, you could modify a gym bike for your test. First, you’d have to decide whether the gym bike could provide enough resistance. Unfortunately, Wingates require a constant mechanical resistance (some number of kiloponds per kg of body weight). If you set a gym bike, to say, 1200 W…it would vary the resistance electromagnetically based on your RPM such that you perform the correct amount of work per unit time. I don’t think you can set (most) gym bikes to an actual resistance (force) setting…they are all done by work / metabolic estimates. Assuming that you COULD get past this obstacle, you would need to have an electronic gizme that could count how many times a beam flashed past a certain target. I guess you would probably have to stick a piece of reflective tape onto the flywheel of the bike…oh, man, this is a nightmare…
I think it would be easier to find somebody you know who works in a lab with access to this stuff. Either that, or you could try timing yourself while running at different distances (e.g. 60 m, 100 m, 200 m, 400 m), and then compare yourself to norms. Based on your relative performance at each distance, you could get an idea for your alactic vs. lactic fitness. For example, if you scored in the 60th %ile for 60 m, 55th %ile for 60 m, and the 30th %ile for 200 and 400 m, you would probably have a high “peak alactic power production” but a low “anaerobic lactic capacity.”
Obviously, basic alactic power is pretty easy to determine using the vertical jump test (there is a simple formula you can use to get abs. W and W/kg). Alternatively, if you have access to digital timers, you could do the Maragaria stair test…
