Multisports Athletes: double threshold juice >= squeeze?

Here is some data indicating that middle distance ‘Double Threshold’ work is really just sweet spot for runners. Special thanks to Mark Burnley for turning me on to this data.

In the image below the y-axis is blood lactate & the x-axis is time in minutes. So basically TTE for three different intensities…severe (filled circles), heavy (open circles), and moderate (filled triangles). The workrate for heavy intensity is the lower bound for the 95% confidence interval of CP. The paper doesn’t explicitly say what that is…but mean CP (best fit of 3 models calculating CP) was 250W and standard error was 5W…so 250W - 2*5W = lower bound of 95% CP CI = 240W.

That’s just about sweet spot.

Now look at the lactate concentration at the 5 minute mark. A little over two. So if this was your data and you did 5x5min intervals at that intensity your blood lactate is likely to be right around that 3mmol target.

This is way more detail than anybody else on this forum is interested in. :smiley: But, anyhow, just closing the loop on this. Image taken from ‘Muscle metabolic and neuromuscular determinants of fatigue during cyclingin different exercise intensity domains’, Black et al

you underestimate some of your forum-mates :smiley:

Thank you.

TLDR?

This is a complete sentence.

3 mmol is 85% ish for me. But only after a block or two of tempo/ low sweet spot.

Remember some people consider anything between the two thresholds to be “threshold”

Why does this make you think switching sports within the double threshold day is required?

Don’t think i said you need to one of each, but you do need to figure out a way to balance out the hard workouts between three disciplines. One way to achieve that is to do a hard workout for two different sports in the same day. Sorry for any confusion.
