Measure EVERYTHING 


As Galileo said ‘measure the measureable, and make measureable what is not so’

This current season I have made a concerted effort to measure as accurately as possible how much work we do and at what intensity. Now obviously I have always recorded this, but this season I took it to the next level (for us) and tracted intensity, volume and rest for every individual athlete. 

We got nice wee graphs like this

For the overall cycle.

And this for each individual

Which is kinda cool. It showed very clearly where people where getting sick for example. 

So having this information is great and it got me thinking, what else can I record that will provide me usefull information about the state of the athletes in my program.

A few day thinking and I came up with a list of things that, if I could record and track them,  could potentially provide useful insight.

(I am 100% sure that there are better coaches than me out there already recording this stuff and much more)

  1. Hours sleep
  2. Sleep quality
  3. Mood
  4. Resting Heart Rate
  5. Hours of training
  6. PRE
  7. Weight

Hours sleep is easy, every morning they tell me how many hours they had.

Sleep quality is rated out of 5, with 5 being excellent and 1 being insomnia. Right now we are going with them rating it but I think that some sort of sleep tracker and a raio of restlessness to sleep would be better. To give me a figure I can track I simply multiply the hours by the quality

Mood is done a day behind so they give me a rating on how they felt yesterday.

I plot a graph of Mood and Sleep quality to see if there is any correlation

(Blue is mood

Orange is sleep)

Resting HR they take in the morning before training on an app on their phone.

PRE and Hours of work I collect after each session. Hours of work is not how long the session lasted but rather how  much time was spent working (session length – rest intervals)

After a quick google search I found that I could use this information to measure Acute (ATL) and Cronic (CTL) training load or Fatigue and Fitness. Lots of formulas later and these combine to give a Training Stress Score (TSS) or ‘form’ so in theory I can see at a glance when they are getting more fatigued and I need to back off a little or when I can push them. 

The blue bars are fatigue and  the orange line is fitness. When the orange line goes above the blue bars this represents a more rested state (very basically) 

Anyway…..it takes weeks of collecting this stuff for it to be at all representative of whats happening so I have started now hoping that it proves usefull next season.

As yet I havent started recording weight as I cant beside if using base metabolic rate and body composition is providing me useful enough information for the time spent collecting it
