Fartlek, training to gain resistance

Fartlek It is one of the terms that is part of the universal language of running. Fartlek is a swedish word which means “speed game” and give name to resistance training method developed by Swedish coaches Gösse Holmer and Gösta Olander in the 30s

Almost one hundred years after its implementation, this training method continues to be widely used in athletics and also in sports. running popular.

In this article we are going to analyze the benefits of fartlek, how to do it and what it is for.

Fartlek or variable continuous training

Resistance training methods can be grouped into two types: constant continuous training y variable continuous training (fartlek). Continuous training is characterized by no recovery breaks.

The training continuous constant serves to improve the aerobic resistance and, in summary, it consists of traveling a long distance (more than 30 minutes of continuous running) at constant intensity, no change of pace and without taking recovery breaks.

The training continuous variable or fartlek, instead, introduce changes of rhythm which can be forced by the terrain or the speed of the runner. That 'adaptability' to changes of pace is why its creators baptized it as a “speed game” (fartlek).

Fartlek is a highly effective and versatile training method, used in the running to improve la resistance, speed and aerobic capacity.

This type of training combines intensity intervals with lower intensity recovery periods; Depending on the level of the runner, recovery can be done by running or walking.

It is a training in which there are no breaks for recovery; You do not stop running and alternate changes of pace (it can also be done using ''CA-CO'', which is WALKING and RUN; this option is the most recommended for beginner runners or for runners who are returning after a long time break due to injury, illness...), it can also be done on varied terrain, which makes it a powerful tool for runners of all levels.

Benefits of fartlek training

Let's see below the benefits that the variable continuous training method or fartlek can bring.

• Improvement of aerobic and anaerobic capacity. Fartlek involves alternating intense rhythms (depending on our goal, more or less intensity) and softer rhythms. This It helps improve the aerobic capacity, which is the body's ability to use oxygen during prolonged exercise, such as anaerobic capacity, which refers to the ability to perform intense efforts for a short period without depending as much on oxygen.
• Increased resistance. The variability of rhythms in the fartlek simulates the variation in intensity that can occur with changes in pace in the race. This improves mental and physical resistance, preparing runners to cope with different conditions during a competition. In the winter season, some athletes who prepare cross (a long-distance athletic modality that takes place partially or totally in cross country) they usually use the fartlek in their training. Cross country is a modality that is run on a circuit and in which a constant pace is not maintained; 4-5 laps are usually completed (depending on the competition) on a circuit of about 2 kilometers in which there are many turns, ups and downs, irregular surfaces... The fartlek can simulate what happens in a cross-country race.
• Burning calories. Of interest, high-intensity intervals in fartlek increase calorie burning during training. This can be beneficial for weight loss or maintaining a healthy weight.
• Specific training for races. The fartlek can be adapted to simulate the conditions of a specific race (such as a 5K, a 10K, or even a half marathon), greatly helping runners adapt to the paces and challenges they will encounter in real competition.

Without going much deeper into other more specific benefits for elite athletes, as a summary we could indicate that fartlek promotes improvement of rhythm and speed, allows you to obtain a diversity in training, helps improve the mental preparation and adaptation to diverse terrain facing the competition.

Alternating between faster and slower paces helps runners develop a better sense of rhythm and speed. Fartlek allows you to vary training and avoid monotony, something that can be especially useful for maintaining motivation and avoiding stagnation in performance.

It is also notable that high intensity intervals in fartlek they challenge the mental resistance of runners, helping them overcome fatigue and improve their ability to manage discomfort during races; and if the intensity of the intervals varies depending on the type of terrain (uphills, downhills, uneven surfaces) it can also be of great help as preparation and adaptation to the different race conditions that the athlete will encounter. 

How to do fartlek training

We have already seen the benefits of fartlek, so now it is time to explain how to perform fartlek training:

Heating. We will start with a proper warm up to prepare the body for effort. Initially we will do joint mobility exercises and then we will start running 10'-15' depending on our level and at the end we will do a little running technique.

Interval Run. Depending on our objectives we will do a number of repetitions or others during the race, alternating between high intensity intervals and lighter recovery. For example, a runner with a 10K goal might start with a 6 x (2′ + 1′) fartleck doing the 2′ a little faster than the first threshold and easy recovery minute. Instead of going at a rhythm you can also do it by pulse. The ratio of time between intervals and recovery can vary depending on your goals and fitness level.

Variety of rhythms. It can be played with different rhythms and interval durations. You can run short, fast intervals, or longer, moderate intervals.

Varied terrain. If you are an athlete who prepares cross-country, choosing varied terrain (dirt terrain with moderate ups and downs, with curves...) will be very interesting and positive to achieve a good preparation for this modality.

Back to the calm. We will have to finish the session with a phase of lowering heart rate by doing a very light jog of 3'-5'.

Variability. Alternating between fartlek sessions and other types of training, long runs and recovery days is very convenient to maintain a balance in the training program.

Application of fartlek training by levels

Beginners. Beginner runners can start with shorter intervals and longer recovery. This allows you to gradually adapt to the intensity and build a solid base.

Intermediates. Intermediate runners can experiment with different work-to-recovery ratios, progressing to longer, more challenging intervals.

Advanced. Advanced runners can implement the fartlek as part of their weekly training plan. They can incorporate race-specific intervals and simulate competition conditions.

In summary, fartlek training in the running provides wide range of benefitsat improve endurance and speed until developing the mental resistance and the adaptability to different race conditions. Its flexibility and versatility make it an essential tool for runners looking to improve their performance and enjoy variety in their training.
