Metabolic Efficiency Training

Metabolic Effitiwhatika…..

I had just finished the Sean O’Brien 50 mile race and my next race isn’t until early August, Angeles Crest 100. This leaves me with 5 months of training. With so much time in between I’ve decided that I was going to play around with my training and try to improve my Metabolic Efficiency. I will not go into detail assuming most of you heard what it is, but here are a couple podcast links if you do not.




There are a couple tests that are recommended if you plan to use the metabolic efficiency training. This first test is the blood lactate test and the second test is the VO2 max test. The two test combined can give you a better idea of how to train and why the metabolic training is a GOOD idea. I set up an appointment with Gareth at Trio Labs in Brentwood (Los Angeles), CA.

BLOOD! Lactate Test

Of course, the test is not as dramatic as the title from what I experienced, but others may beg to differ.

From what I understand, lactate is a fuel source for the muscles, but at some point the lactate builds too fast that the muscles cannot use it fast enough. I was told to imagine a cup overflowing with water.

There are two methods to take a blood lactate test which is the stationary bike or treadmill; I chose to use the treadmill. In this test you start off slow and Gareth will slowly increase the speed. Every so often Gareth will ask you to jump on to the sides of the treadmill and take a tiny blood sample from one of your fingers with a blood lactate gadget. Gareth will use the lactate levels and heart rate at specific speeds to plot the points on a graph.




The blood lactate test is used to determine the different aerobic levels. Each level is a different training zone which helps to design a training schedule. A good example of a training schedule is the 80/20 Rule. I plan to train in zone 1 & 2 80 % of the time, leaving the remaining 20% to be used for zones 3 thru 5.

What it means to ME

The blood lactate test basically told me that at my current aerobic level I should be training between 129 – 154 beats per minute (bpm) which should be around, but not over a 7:48 pace. If you didn’t listen to the links, in metabolic training we use the heart rate to determine stress levels not how we feel during the run. This is the zone that will allow my body to strengthen its aerobic base, which in turn will allow me to run a faster pace in the same bpm zone.

I figure my training zones would look like this.

Data includes VO2 Information

VO2 Max Test or the Test from HELL

The VO2 max test is used to measure the volume of oxygen one can consume while performing at maximum capacity. Trio labs use this test to determine what types of fuel is being consumed at any given speed. The goal is to burn a high percentage of fat versus carbs for as long as possible. This data in conjunction with the blood lactate data gives a refined direction of what one would need to do for optimal training. The lactate test by itself is like a plain map, however, when it is combined with the VO2 max test it turns into a shaded topographic map.


Originally we knew that I should be training somewhere between 129 – 154 bpm, but we can clearly see that my optimal training is at 145 bpm. This is where I use the most fats to carbs ratio and lactate levels stay low. Using the 80/20 rule, I would be able to use this data to significantly improve my body’s metabolic efficiency and performance.

Conclusion

Metabolic training is a great idea since it forces you to build a 6 week base. After the 6 weeks you would start to incorporate the speed training. This prevents a person from getting injured from training to hard too soon after races.

In two months I plan to go back to Trio Labs to see what kinds of improvements have been made.
I also plan to log my training data such as training days, meals, etc.., but I still need to figure out how to go about logging it all and how to represent it.

Goals:

·         Lower lactate levels at each point.
o   Move the 1.1 under 1 mmol
o   Lower the 2.7 & 5.3 by correcting my running form at higher speeds.
·         Reduce my beats per minute at higher speeds.
·         Move the metabolic efficiency point (Fat and Carbs Intersect) towards the right.
o   Improve the body’s ability to burn fat at higher speeds.

What I Need to DO:

·         LISTEN TO MY COACHES KATE & JIMMY D FREEMAN
·         Include more protein in my pre-training meals.
o   I will probably wake up early and make 2 eggs with buttered toast.
·         Reduce consumption of beer.
o   NO WAY am I stopping.
·         FOCUS…FOCUS...focus on training in Zone 1 for 6 – 8 weeks.
