Since max aerobic power (Vo2 max power zone) is fixed and has a genetic limit (Assuming one is trained and Vo2 max power won’t rise), how come it’s tied to FTP power increases? For example, let’s say one’s Vo2 max power zone is maxed out but one keeps improving FTP power, is it still accurate that the Vo2 max power zone keeps increasing?
For example: FTP 300 watts. Vo2 max power zone: 106% to 120% or 318 watts to 360 watts.
Several months later: FTP 310 watts. Yet because All zones tied to FTP: now Vo2 max power zone: 327 watts to 372 watts.
Please explain because now one might NOT be able to complete TR Vo2 max power workouts.
