ftp test
a few weeks ago i've done the "effort test" to obtain the 2024 certificate to have access to the races.
During this test the doctor had a bike wich measure cadence, power, kcal etc. Basically was one of those bikes you can find at the gym.
Since my brother in law has a gym with almost the same bikes, i would like to know how to replicate this watt measure.
The doctor was adding 25watts every amount of time (wich i suppose depends on the bike itself).
To make the exactly watt measurement should i start from x amount of watts and then increase the resistance effect every minute until i do not have more energy.
is this correct?

This is called a ramp test. A typical protocol is to warm up and then increase wattage by 20W steps every minute until you eventually fail. Your FTP is then estimated as 75% of the max power you achieved in the ramp. The starting wattage for the ramp is not that important as long as it is relatively easy.
Edit: The gym bike might well have a built-in ramp test program. Worth a look.

Yes, if it has ERG mode that you can adjust power to set targets. Then just follow the ramp protocol with manual 20W power steps every minute. Make sure you do a good warm-up before starting the ramp.

Anyway, the estimate of 1 hour power from the ramp is to use a range of 72 - 77 % of the best 60-secs of the ramp test.

gawd, i was youngish then. Thanks Robert.
It was weird, i started collecting power data in 1994 (i was 25 then) but wasn't overly sure what exactly it meant. I turned up to Uni (to do a degree in sports science in 1995) and it literally took a month for it all to come together. I remember riding a "Kingcycle" (there's something to google) at 200 W and proclaiming that this was about the average power of a road race (which caused raucous laughing, as everyone said it was way harder than that). Turns out that many of the road races i do are less than 200 W (and it's simply the stochastic nature that make them hard). i then started collecting data on other riders (gawd this was before stuff was downloadable) and worked out power curves and estimated powers from a ramp test for all sorts of durations. Happy days!
