Zwift only uses FTP (95% of 20min test) as a benchmark number. I would also like to have benchmark power numbers for 5min, 1min and 5sec. Here’s why:
All workouts are based on FTP. For example, a VO2max workout may consists of several intervals at 125% FTP. But this is based on the assumption that everyone has a 5 minute Maximal Aerobic Power (MAP) of 125% of their FTP power. Same goes for the workouts focused on 1min Anearobic Capacity (AC) and 5s Neuromuscilar Power (NP).
It’s more efficient to train to your actual 5min/1min/5s numbers to improve these types of efforts, then to train to estimations of them.
For example, my 5min power is relatively low to my 20min power. If I want to improve my 5min power and do workouts that are based on X% of FTP instead of my actual 5min power, I would fatigue to fast and not complete/ineffectively perform the workout.
The other way around is that someone with a relative high 5min power compared to their 20min power (doing that same workout based on X% FTP) would not t push themselves hard enough, so this also results in an ineffective workout.
Therefore, I request
- the benchmark numbers of 5min, 1min and 5sec next to the FTP 20min benchmark.
- the ability for workouts to automatically adjust to your personal 20min/5min/1min/5sec benchmark according to the nature of the workout
