Long easy/moderate runs are endurance training, where you become able to run far in a long time. Finding your Lactate Threshold and practice LT – training, you become able to run faster i.e. with a higher intensity in a long time. In other words, performing lactate threshold training which is intensive marathon training intervals, you learn to run faster and longer. We will explore how the lactate threshold boost your marathon performance below.
What is Lactate Threshold – LT?
The Science has shown more precisely, what causes the accumulation of lactate in the working muscles during hard work. But in general, the Lactate Threshold – LT is a very reliable and powerful marker of performance in aerobic exercises, because it works in practice. Lactic acid or just lactate is called a waste product of the energy production. It paralyzes the muscle and causes a burning sensation.
The lactate threshold LT is a threshold where a given work intensity leads to the lactate volume in the muscles begins to rise pretty much. Lactate produces continuously by muscle work. However, if there simultaneously is sufficient Oxygen, will excess lactate removes via the blood.
At low work intensities, there is a balance between the production of lactate and the elimination of lactate. Lactate threshold or just LT, is thus the highest level at which a stable level of lactate can be maintained.
It means that production and removal of excess lactate in the blood are equal. LT is therefore at the intensity level, where the lactate volume just does not inhibit the muscle work. When the work intensity increases, the lactate volume increases equivalent since a major part of the energy produces anaerobic. Lactate accumulation leads to muscle challenges. The muscles paralyze and become more and more painful. It is therefore necessary to reduce the working intensity lower the pace to avoid further pain and discomfort.
Lactate Threshold Training
The ability to “move” the LT, so you can tolerate more improves by running nearby the LT. It’s also the level, where you best improve the endurance. The most practical way to describe the LT level is on basis of the maximum Oxygen uptake.
If you are common jogger, your LT will probably be around 60-70 percent of your maximum Oxygen uptake, whereas the anaerobic threshold at very well-trained runners, will be between 80 and 90 percent of the maximum oxygen uptake.
The lactate threshold theory
If you want to experience how the lactate accumulation feels, then try to stand up with your arms horizontally in 4 minutes, and you will experience how it feels. At one point, your arms begin to shake and pain, and finally there is so much lactate accumulated in your arm muscles, that you simply must let them fall down.
Lactate measures often in MMol per liter blood. The lactate threshold theory compares the speed / heart rate with lactate accumulation in the blood. LT for the majority is measured to be about 3-4 MMol per liter blood. Highest lactate accumulation, a person can obtain is about 19 MMol per liter of blood.
As you see there are a lot to gain, particular as beginner who wants to improve your running skills. When we move our LT it means, that we run in a pace nearby our LT and hereby move it over time. In this way, we will run longer with a higher speed before the limit is reached.
If you want to find your exact LT level, you have to be tested on a treadmill with modern laboratory equipment. An expert measures your lactate concentration at different speeds and finds therefore exactly the threshold.
LT can also be found in some practical tests. For most people the maximum speed you can run on a half-marathon, will be similar to the pace at LT. If you have not run that far yet, you can use your 10 km time and add 8 – 10 seconds per kilometer. Let’s say you run a 10 km in 50 minutes with maximum effort.
LT will then be, at an intensity corresponding to 5 minutes per. Km plus 8 – 10 seconds each km. Today you can get a Heart Rate Monitor – Sport Watch, and it is more convenient to use the working heart rate to define the LT and your other training zones.
Manage Your Training with Heart Rate (HR) and Heart Rate Monitor (HRM)
Heart rate training with a Heart Rate Monitor is a training method, where you continuously measure your heart rate, so you can stay in a certain heart rate zone, depending on the purpose with your training. If you want to use heart rate training as preparation for a marathon race, you need to acquire a Sports Watch or at least a Watch with a Heart Rate Monitor (HRM) either built-in to measurement on the wrist or as a separate belt around your chest.
Correct performed heart rate training also has the benefit that you do not have to worry about whether you train optimally in relation to your physical capability, since you make two preliminary personal tests and enter the results in the Watch. The HRM will reveal whether you are very tired, by an elevated heart rate at a given pace, compared to what it usually is at that given pace. Let’s say the HRM shows a heart rate of 150 beats/ min. on an easy jogging! Then you probably have to take an extra rest day. It’s also easier to avoid over training and possible overload injuries.
The HRM is a great management tool when running, your heart rate is a very precise target for the intensity you expose your body for, which gives certainty in the daily training. All persons from untrained to elite athletes can have great benefits of heart rate training, because the heart rate is individual from person to person. Thus, the HRM gives you the best conditions to planning and monitor training and competition with great accuracy.
Intensity and Lactate Threshold Training
HRM Training makes the training more focused and easier to manage in a fun and flexible way with personal training zones that manage your training intensity and hereby your Lactate Threshold Training progress. Well-planned training, where you use the heart rate HR and HRM as guide, is based on your current training level and your physical condition. HR training is based on how hard or how easy you train. The intensity is the keyword. An HRM is a very good training tool, if it uses correctly.
Therefore, it will probably require some discipline in the beginning to obtain the best results. The HRM’s primary function is to measure the heart’s frequency – how many times it beats pr. minute. The watch gives from your heart rate accurate information about, how hard you work – the intensity.
