I think I’m a contender for the award for the post with the most previously unheard of acronyms in the title.
These acronyms being TRIMP : CTL : TSB : ATL
Essentially they help you broadly understand the effect of your training on your body. Answering questions like: “Am I really improving?”; “Am I too tired to train?”; “How good is my taper?”; that sort of thing.
They work over any endurance sport. You can use them with power meter info from bikes (but let’s ignore that) and I’m going to focus on their most useful application with your heart rate data.
You are still going to do your pace based training and probably all the same old training you have been doing BUT you’ll be getting a better insight into how it’s all fitting together. So maybe you can tweak it a bit.
It borders on rocket science but you don’t have to understand the formulae. I’m reasonably mathematical but I can’t be bothered to even try to understand how they work. I haven’t got the time. I’m just going to use and interpret the pretty graphs they produce!
If you use SPROTTRACKS v3 then you will get the info with the TRAINING LOAD plugin by mechgt. I would imagine you will find it in TRAINING PEAKS and all other good software packages for athletes. SPORTTRACKS is free tho!
I’m learning a bit myself so I will revise this post if my understanding changes. But I’m going to keep it simple anyway to start off with.
TRIMP: If points make prizes then how hard you try and how long you try for in your exercises MAKES TRIMPs. TRIMPs are the points for your heart working in all the various zones with more points for when it gets to heady heights. So my 5k PB TRIMP is about 80 but tonight’s turbo session was 140. Doesn’t really matter. I could do a 5k tomorrow and get 82 and not get a PB it’s not (that) important in itself. Obviously my 5k PB was in a high HR zone for a little while whereas tonight’s turbo session had it between 162 and 173 for over 40 minutes. So tonight I didn’t work so hard but I worked for longer.
ATL looks at YOUR TRIMPS over a short period. So it measures how knackered you are. When you are really knackered you just ease off the training a little.
CTL looks at your TRIMPS over a longer period and says that’s how fit you are (compared to YOU previously). So ideally CTL will trend upwards.
TSB looks at the balance between CTL and ATL. This makes sure you taper properly and are as fresh as possible for the event without having lost too much form. [Maximise TSB, don’t let CTL fall by 10%]
In theory my fitness curve should dip soon as my training program has an easier week. So, by the end of April 2012, I should have one of those classic graph/curves showing continually rising fitness interspersed with the occasional dip allowing for recovery. We’ll see (just like the text books!!).
If you spend more time with your stats than training (like me) then you MUST look at this!
