List of commonly used terms and definitions

I don’t know if this sub forum is the best place for this question and maybe I am the only one with this problem, but keeping track of all the alphabet soup gets a little overwhelming.
I have been listening to the podcast since almost day one and mostly listen on commutes, so no real time to write anything down. I will either have to remember or go back and re-listen to the podcast (time consuming).

Is there anyway since there is now a forum to create an almost wikipedia like post to post common terms and abbreviations with short descriptions and/or hyperlinked longer descriptions as they pertain to cycling?

I am referring to things such as: Sub Threshold, Aerobic Threshold, Anaerobic Threshold, LT1, LT2, VLamax, VO2max, LSD, FTP, Cardiac Drift, 3 zone model, etc.

Example of what it could look like is:

LSD: Long Slow Distance ride. Usually performed slightly below aerobic threshold (could be hyperlinked to the definition of aerobic threshold) or roughly 85% of Max HR (could again be hyperlinked).

If this doesn’t seem helpful then forget it and please delete this post, but after a while I seem to have forgotten more than I have learned and maybe this would also help those new to the training world as well.


This would be a great resource.

I agree, this would be super! Probably a good one for the main fastlabs page. Links to specific episodes for the library members too! Of course as we have heard time and time again on the podcast, terms are used and abused frequently in “popular sports science” discussion so definitions do vary. But adopting a consistent set of terminology at least among the fast labs crowd would make discussions easier!

This is a great idea! I’m sorry to have missed it in the sub-forum location initially, but this is something that I have been working on and am continuing to develop over time. So it is in the works!

The list that @yourrealdad started with is excellent. If you would like to add additional terms, I would love to utilize our community-sourced suggestions to make sure we have the most comprehensive list to start with.

Surely this could be crowd sourced in a cloud-based document, eg. Google Docs. Members of the forum would be allowed to edit this document, thereby helping the list grow. At a point in time, it can be updated on a forum page.

This shares the work required, and takes into account Dave’s post relating to a busy Fall (I call it Autumn) and Winter period.

@geraldm24, let’s give it a shot with a Google Doc like you suggested. Here’s a simple sheet to start with, so let’s see what we come up with. You should be able to view and edit this document. I’ll leave this link open for a while and check to see how we’re doing on it.

I should add that this is meant to initially start with a sourcing of the terms. I’ll continue working on organizing them and generating definitions once we have a solid initial list. This will be a longer-term project, and one that will be fun to watch evolve.


Thanks @Ryan,

I’ve added a list of abbreviations, with some comments to the right of each one.
I also added some other terms in the physiology heading.
Hope this is what you were looking for - excluding me expanding on the abbeviations.

Thanks @geraldm24. This is great!

Hey all, here is a doc I put together some time ago. I don’t have time at the moment to copy these elements into the sheet, but I uploaded to Google Drive as an editable link. The definitions are pretty high level, but could certainly be augmented with further detail and linked references.
Hope this helps!
