Posted in general discussion about this but wasn't sure if this was a better spot.

Using a Garmin Edge 705 now and I upload to SportTracks. The fitness measurement plugin I found will measure CTL, ATL, TSB, and TRIMP and chart all this out for me. Anyone able to shed some light on how I can use these figured to help improve my training?

Maybe a cycling specific article or something?

I like looking at the data so charting these kind of things is fun. Plus if I can get some benefit out of it all the better.

Thanks!

And for several of those metrics but not all you would need a powermeter to go with the 705. I'll second the google wattage forum there is more info on that there than you will probably want.

That is probably true, some people get down in the weeds, they tend to get down around the roots of those weeds.

The wattage forum will certainly be a good place to go for info.

It sounds as if the Garmin calculates a TSS score based on TRIMPS in the absence of a powermeter. I think the TRIMPS value is based in heartrate, so asking about it in Wattage may be a little off topic.

I'd get the book "Training and Racing with a Powermeter" for an official explanation.

Over simplifying:

All those acronyms are based on weighted averages of TSS(Training Stress Score)/day either long term or short term with different decay rates.

Training Stress Score is based on the wattages produced during a ride and your Functional Threshold Power in watts.You may have to estimate this in Sport Tracks to use the calculated values.

ATL is Acute Training Load in TSS/day - what youv'e done recently.

CTL is Chronic Training Load in TSS/day - what you've been doing over a longer time period up to now.

TSB is Training Stress Balance - the difference between what you've been doing recently and what you've been doing over time. A negative TSB means that you are doing more work recently compared to what you are used to doing. A positive TSB means the opposite.

Some people used TSB to plan peaks. (Positve TSB, CTL high as possible), or plan recovery to reduce fatigue. (very Negative TSB)

The plugin I'm using does all this off of TRIMP I'm guessing.
I've love to get a power meter eventually but it's not a priority since I don't race or anything.

I'd simply like to us they values and any info I can get to somehow show my progress.
