If you are using your Power Meter to get race ready over a period of weeks, the Power Management Chart will become an essential bit of kit. What you’ll be aiming for is to train to get fitter, whilst still ensuring you are well-rested, so you’ll be on top form at the start line.

After a 6 week period, your stats will automatically be used to produce a Power Management Chart progressively, (so at whatever point you look, after the initial six weeks it’ll produce a chart for the previous six weeks). 

How the Power Management Chart is created

Essentially each ride produces a Training Stress Score which we have blogged about previously. Over time these figures are used to create two metrics: The Acute Training Load and the Chronic Training load, with the most recent TSS scores weighing more heavily, so current fatigue is taken into account. These, in turn,  create the Training Stress Balance.

Acute Training Load (ATL)

This is a seven day metric that shows the short term effects of exercise.

Chronic Training Load (CTL)

This is a forty-two day metric, (6 week), which shows the long term effects of exercise.

Training Stress Balance

This is the metric for ‘rest’. It’s produced by:

Chronic Training Load – Acute Training Load = Training Stress Balance

Before a race, the ideal is to be fit and yet fresh. ‘Fresh’ being well-rested, rather than smelling of roses!

 

What you can learn from a Power Management Chart

The first thing you’ll learn is that if your Chronic Stress Score is higher than your FTP, you’ve got fitter! Result.

But….

Acute Training Load (ATL) > Chronic Training Load (CTL) means you are very ‘fit’ but because you are fatigued you won’t achieve Peak Performance on race day.

Whereas Acute Training Load (ATL) < Chronic Training Load (CTL) which gives a positive Training Stress Balance means you’re well trained and well-rested, ready to roll out your A-game! Bring it on.
