Great Scott it works, it works! My results are in for lactate blood training. Please see my previous post for details. I’ve done it order to get fitter with my personal trainer. In my last post I said that the theory said that if you train properly you may be able to delay the lactate build up in your blood and exercise at a higher work rate without risking injury.

Fig 1 : Power in Watts (x axis) against heart rate (BPM) and lactate present in blood (August and September 2023 after 4 weeks training)

In Fig 1 above there are two graphs, the red and blue lactate measurements.

Over four weeks training (With slow speeds at 90 RPM on a bike) my lactate threshold has improved and shifted to the right meaning (See yellow arrow above) that I have got fitter and can tolerate more exercise before my lactate goes above 2.2 mmol/L. You can also see my heart rate has lowered at the same power exertion.

I’m really pleased that this exercise in measuring my fitness and then training using lactate measurements has improved my fitness. There is the theory.. but when the theory becomes reality it is wonderful 🙂
