Using Lack of Pyruvat(LOP) for intervaltraining.

Designing specific training programs based on LOP and lactate accumulation has proven to be a very successful concept in the past decade. Such regimes can increase buffering capacity, lactate exchange, and lactate combustion.

Interval Programs If you are targeting a specific intensity, based on a particular race or goal you are trying to achieve, choose this intensity from the LOP and lactate accumulation graph. Then decide the time that the interval should last for. Simply multiplying this time by the actual lactate accumulation value will tell you amount of lactate that is going to accumulate during the effort. By then choosing the interval recovery intensity, you can see how quickly the athlete can combust the accumulated lactate.

With this information, you can then create individual interval programs based on the current physical status of your athlete, and the goals you want to achieve in future. 
In the graph to the right, we show 3 examples:

Understandig Lack of Pyruvat curve.

The graph to your right shows the lack of pyruvate (or lactate, grey line) and the actual lactate accumulation (purple).

Lack of pyruvate curve is shown in mmol/l/min of lactate clearance. It shows the ability to recover from lactate accumulation in relation to the intensity (speed or power). At anaerobic threshold it runs to zero – the aerobic metabolism is saturated with lactate and no additional lactate can be combusted.

The purple curve shows the rate of lactate accumulation. This occurs at intensities higher than anaerobic threshold. The steeper the curve, faster lactate accumulation at any given intensity.
