So, I am trying to understand different things (mostly things I have heard on the Ask a Cycling Coach Podcast) about fasted training. Here’s what I have heard:
- You have glycogen stores for about 70-90 minutes of training.
- “Easy” aerobic efforts largely utilize oxygen and fat metabolism for fuel.
- Don’t do anaerobic workouts in a fasted state.
- Don’t do fasted training on workouts longer than 90 minutes.
a. If 1. and 2. are true, why shouldn’t I do more than 90 minutes of fasted training at an easy level?
b. If 1. is true, shouldn’t most mid-volume workouts under 90 minutes be okay in a fasted state even if they have anaerobic components and sweetspot/threshold work? (As long as I use adequate recovery nutrition? I realize that those workouts won’t increase fat metabolism, but this is mostly about eating early in the morning or too close to the workout).
Can anybody help me make sense of this? Specifically, I am currently starting SSB2 (mid-volume) and my Thursday schedule makes eating before workouts really inconvenient. I have tried the half-hour high-glycemic thing last season, but I don’t really like it.
