Ciclismo Consciente – Entrenamiento en Zona 2 y Entrenamiento DFA alfa 1.

What is DFA alpha1? DFA alpha 1 is a heart rate variability (HRV) metric that allows tracking of the aerobic and anaerobic threshold.

What is DFA alpha 1?

TLDR: In short, DFA (detrended fluctuation analysis) alpha 1 measures the noise spectrum of your heart. As you ramp up the intensity of a workout and your heart has to work harder, the kind of noise – which the value of DFA alpha 1 represents – changes. Recent research has shown that DFA alpha 1 crosses below 0.75 at your aerobic threshold [1] and below 0.5 at your anaerobic threshold [2]. For a more detailed explanation, check our in-depth blog post about DFA alpha 1.

What is zone 2 training? Zone 2 is steady training just coming above the easy zone, It’s not moderate or anything above. The main benefit form zone 2 heart rate or zone 2 power is that it builds aerobic base and endurance. By Improving aerobic capacity this improves your ability to maintain a faster pace for a longer period of time. Of course you still need to do the higher intensity efforts but zone 2 is the basis and foundation from which to begin to build your faster pace. If you have a strong aerobic capacity it will also allow you to recover quicker between those higher intensity efforts. For example, with a better aerobic fitness, you will be able to perform intervals with a shorter rest in between and hit pace stronger.

Why is Zone 2 training important?

One of my coaches Mark Shepherd is very critical on me for my training and the majority of his training he gives me is all in zone 2. He stresses the importance of zone training every week. I also believe in this training; before Mark I went on studies on how to improve and the main finding was I was training too hard although I thought it was easy. I had my zones adjusted to my heart rate max and since that study in 2015, I have improved a lot from training in zone 2. So when Mark gave me my training I was no stranger to this. Of course lots of people think they are doing it right but I see it all the time on Strava and can tell it’s wrong. Zone 2 training should be a big bulk of your weekly training and for the benefits mentioned above it also leaves you feeling like you can go on for ever, fresh, recover and therefore really target your hard runs and not get fatigued, which of course will keep the injuries away. If the injuries stay away then to me that’s a major importance in any training, not only will you get consistent training which is the key, but if you get consistent training you are very likely to improve. If you keep over training and get injured you will just end up chasing your fitness and making excuses. With zone 2 training you should be able to maintain a conversation very easily; I always like to focus on form as it’s easy to do whilst at this heart rate. What is there not to like about it? It’s a well-known method and your body needs to repair – you just cannot keep breaking your body down with hard training. I always point out to people even the best marathon runners in the world run slow miles.

How to work it out?

Firstly you need a watch and a heart rate monitor. You need to know your heart rate max and once you have that you can put your heart rate in many calculators online HERE or watch my YouTube videos HERE and you will get your zones from there. You do need to make sure the HR max is right, you can do tests like: 5k Time Trial, FTP test, coopers test, VO2 Max lab test and so on etc or even use a recent race result. Do not use your watch automatic/present zones as 9/10 times they are wrong zones. Once you know your heart rate max you can get your zones. Don’t go by pace or mileage, I just go by time and follow the zone strictly. By sticking to lower heart rates, over time you will find that you are likely to increase your pace at the same heart rate output. This is due to increased aerobic efficiency – yes I had to walk up hills to start off with but that was a way my body was telling me I am pushing too hard. You may have to walk but in time it improves. When you become more efficient in time you will then be able to do more training hours at a lower heart rate.

Heart Rate Training Zones Feel Heart Rate (beats per minute)
1 Easy 120 – 130
2 Steady 131 – 142
3 Moderately Hard 143 – 155
4 Hard 156 – 165
5 Very Hard 166 – 177
  • Zone 1 – Feels like “Easy/Recovery” – Heart rate 68-73% of max.
  • Zone 2 – Feels like “Steady/Endurance” – Heart rate 73-80% of max.
  • Zone 3 – Feels like “Mod. Hard/Tempo” – Heart rate 80-87% of max.
  • Zone 4 – Feels like “Hard/Threshold” – Heart rate 87-93% of max.
  • Zone 5 – Feels like “V. Hard/VO2 Max” – Heart rate 93-100% of max.

Why do people ignore this method?

People are simply not patient and they expect instant results and that won’t happen overnight. At least 2/4 of my runs a week are in zone 2. When I first did this training it was a few weeks before I saw my pace improve, but found I could train more and on the hard sessions go harder. Over the years the pace is sometimes at a pace which I was doing back in 2015 too hard. I have improved a lot from this but it takes times, it could be weeks or months to see improvement but you have to keep at it and your see the benefits. Stick with it and you will make improvements and of course with anything you will struggle to get quick results so why break your body and get injured when you can train smart?
