How to increase or decrease VLamax in running

Lower VLamax first, raise VO₂max second, raise VLamax last. Ben Tilus shares the 3 step season plan, including the primed interval that trains VO₂max at a lactate concentration of 8 mmol/l without the intensity that raises VLamax.

Step one: lower VLamax
Remove aggressive lifting, hill sprints and massive sprinting. Replace them with sub threshold work that still recruits fast twitch fibres but trains them to use oxygen. A fibre that is never recruited cannot adapt.
Step two: raise VO₂max at low lactate production
The primed interval: 1 to 2 minutes above threshold to lift the lactate concentration, then settle at threshold. The workout now runs at 8 mmol/l instead of 4, without the intensity that would raise VLamax.
VO₂ reps on the lower edge
An intensity that elicits VO₂max but sits only slightly above threshold, with training volume nudged up. Hard enough to stimulate, controlled enough to keep lactate production down.
Step three: raise VLamax again
Once VO₂max is high enough, often several seasons later: 20 second sprints every mile, 200 m accelerations with full recovery, explosive lifting with long rests, 10 second hill sprints.

About this whitepaper

In our previous article, we showed how to find out whether your runner should increase or decrease VLamax. Now it’s time to answers the final question: how to increase or decrease VLamax and How to increase VO2max in the meantime.

Ben Tilus, National and State Champion coach in track and field and XC, shares his 3-step approach when it comes to balancing VLamax and VO2max in runners. In short:

  1. First: lower VLamax. As explained in the previous article, this will decrease lactate production and therefore increase the lactate threshold (or critical velocity).
  2. Second: increase VO2max. This enables the athlete to run fast without accumulating lactate and it enables the athlete to “burn” lactate as a fuel.
  3. Lastly: increase VLamax. As soon as VO2max is high enough, the aerobic energy system is able to burn (clear) lactate quickly. Therefore, it makes sense to increase VLamax / lactate production again.

Let’s learn how Ben Tilus implements these 3 steps in training. Ben Tilus continues:

How To Lower VLamax In Running

To lower VLamax, we first take away anything out of the training program that would raise the VLamax. Examples are:

  • Stay away from aggressive weightlifting
  • Don’t do short hill sprints with long resting periods in between
  • Remove any massive sprinting in general

How To Increase VO2max In Running

Once VLamax (and therefore lactate production) is down, we start to focus on workouts that increase VO2max. The challenge is to keep the VLamax low, while raising VO2max. Why? Because you want to train the aerobic system to burn (clear) lactate, but you don’t want your athlete to produce a lot of lactate at high intensities, because that would increase VLamax.

There is a trick to do this in training. This special training technique increases lactate concentration during an interval (which stimulates VO2max) without having to run at high intensities (which would increase VLamax).

To increase VO2max, I start implementing VO2 reps. But I stay on the lower edge of VO2 rep intensities. Training volume almost always has to go up a little bit as well.

How To Increase VLamax In Running

When VO2max has gotten high enough – probably over several seasons – we can start increasing VLamax again. The INSCYD virtual test (prescribed in the previous article) will show you whether there is benefit to raising your athlete’s VLamax.

To increase VLamax, we stay away from the training strategies that decrease VLamax (described in the whitepaper).

Instead, here are some examples of what I add to the program to increase VLamax:

  • 20 second sprints every mile of a run, or;
  • 200 meter accelerations with full recover (e.g. 20 minutes) in between, or;
  • 8 reps of explosive weight training with long rest (e.g. 10 minutes) between sets, or;
  • 10 second hill sprints with walking recovery (e.g. 5 minutes)

We also continue with VO2 reps, described in the How to increase VO2max section, but now at a higher intensity, since we’re not worried about increasing VLamax anymore.
