Through the Kingston Wheelers I got in touch with Colin Towey a srudent of Sports Physiology at St Mary's College who was looking for test subjects for his final year Thesis.
The benfits for me are that I get a free print out of my Lactate Threshold profile and my V02 Max figure.
Lactate Threshold is effectively the point at which my body is producing more lactic acid than it can clear. Your V02 Max is the amount of oxygen you consume in mililetres per kilo of body weight per minute when working at your maximum capacity (just before you blow up!)
Colin took an initial blood test from my ear, before I rode a warm up for 5 minutes. I then graduated to the test bike where I was hooked up to the computer via a heart rate monitor link and breathing apparatus.
The first test was blood lactate, I had to ride a 3 minute set at a consistant 90 rpm, then rest for 45seconds whilst another blood test was taken from my ear. I then rode another 3 minute set at a higher resistance but steady 90 rpm. At the start of each rest I had to state my perceived exertion level on a score of 1 -20. I completed 8 sets of this test before I was deemed cooked.
I followed this with another few minutes on the warm up bike just spinning the legs and clearing the lactate from my system before commencing the V02 Max test.
the V02 Max test took much the same route, although with the resistance increasing every minute until the I could not hold a consistant 90rpm.
Same again next week and then the results!!
