Plan, Periodise, Train, Adjust and Win Part II

On December 18th, 5 weeks ago, I did the two speed lactate test. Read my blog of 18 December about it.

Today, I planned to repeat it. I tried to copy the protocol as much as possible. So first a Fletcher warming up:

Higher heart rates than 5 weeks ago.

Then the main event, two 1k tests spaced 15 minutes apart. The first one at head race pace. Second one at 2k pace or faster (full out allowed). I looked up my stroke rate of 5 weeks ago. They were 27 spm for the first one and 31 spm for the second one.

Again, a higher heart rate in the second 1k.

So, compared to 5 weeks ago, there are the following differences:

• 2 seconds faster split on the first 1k (stroke rate 0.4 spm up)
• HR 10 bpm higher on the first 1k
• Lactate 0.4 mmol/L lower after the first 1k
• 2.3 seconds faster split on the second 1k (stroke rate 1 spm up)
• HR 7 bpm higher on the 2nd 1k
• Lactate 0.4 mmol/L lower

So I am faster at lower lactate but higher heart rate. This sounds plausible. For the aerobic energy path way, the heart rate has to go up when delivering higher power.

In a graph, it looks like this:

To be honest, I had hoped for a right shifted first point and a steeper curve. You can’t say I didn’t try. The second 1k is a Season’s Best.

I did another lactate test after a 2k cooling down. 2.3 mmol/L

So I guess my aerobic fitness has increased. Next test in 5 weeks.
