Cycling Physiological Assessment (Part 1)

I have always said that the bike is my weakest discipline and no mater what I have tried I have always struggled to make improvements, well lately I have decided to have a scientific look at my weakness and have it quantified and develop a training plan based on this.

To this end I took part in a Cycling Physiological Assessment at Canterbury Christ Church Universities sports science department. This involved cycling on a bike that measured my power output, while my heart rate, oxygen consumption were recoded along with taking regular blood samples to measure my blood lactic saturations.

The aim of the assessment was primarily to: -
  1. Highlight specific strengths and weaknesses of your fitness profile in relation to your sport,
  2. Provide a scientific basis for any training guidance we may offer, and
  3. Enable regular monitoring of any changes in the components assessed
The tests last between 60 and 90mins and take the form of riding up a couple of hills that just keep getting steeper and steeper

So the following table is the output from the tests and show how poor I actually am on the bike: -

Interesting stuff. I'm thinking about doing one of these to see where I am now too.

If you're going to be shedding lbs, be careful not to do it too quickly and lose power...
