where in the body does the adaptation happen?

Training Advice/Discussion

7 years ago 08/30/2016 9:27am EDT

I was running a hard workout of Billat 30/30s yesterday (30 sec at vVo2 max - about 15 sec slower than my mile pace with 30 sec jog rest). I did 35 of them but the number is not fixed you just keep going until you think you have had enough for a very hard workout.

I have been doing the workout for about 5 weeks now and it is quite effective so far.

I was wondering, where does the adaptation happen? Is it in the leg muscles? The heart? The brain? Subjectively it feels like the limiter is not heart or lungs but I know it can be tough to judge these things.

Adaptation can happen anywhere and everywhere. It happens within cells in the form of increased mitochondria, it happens through increased capillarization, neuromuscular connections...

The adaptation occurs in the ankles. As you become more efficient, you can run faster using less energy.

Read Daniels' Running Formula (I haven't read the third edition, but I expect it is substantially similar to the first two editions, which I have read).

https://www.amazon.com/Daniels-Running-Formula-3rd-Jack/dp/1450431836/ref=sr_1_1?s=books&ie=UTF8&qid=1472579091&sr=1-1&keywords=daniels+running+formula

While some on here disparage Daniels as someone who tries to make you fit into some preconceived set of paces, his book actually does a very good job of describing the intended adaptations associated with different workouts and the physiology of the adaptations themselves.

In defense of Daniels, he also goes on to describe what each pace should feel like subjectively and how you may have to adapt your pace to different conditions and how you feel (but all anyone who complains about Daniels focuses on in the book is the pace tables).

Mostly in the brain.
