Functional Threshold Power (FTP) is one of the most important concepts for those looking to improve their performance in competitive cycling. This parameter, which measures the maximum average power a cyclist can sustain for about an hour, has become a key metric for structuring training, evaluating progress, and planning race strategies. While improving FTP is a common goal among cyclists of all levels, doing so efficiently and sustainably requires a science-based approach and advanced training techniques.
In this article, we will explore the most advanced strategies for optimising FTP, as well as common mistakes that can sabotage progress. We will also look at the role of nutrition, technology, and the use of cycling simulators in this process. If you are serious about your performance on the bike, FTP optimisation is a path that will significantly enhance your capabilities.
The importance of FTP in cycling performance
The relevance of FTP lies in its ability to serve as a direct indicator of performance in prolonged efforts, which are often key in long-distance races and events. For competitive cyclists, FTP determines how fast they can maintain effort without fatigue. It’s not just another metric; improving your FTP means enhancing your ability to sustain intense efforts for longer, which can make the difference between reaching the podium or falling behind in the race.
In both training and competition, FTP is a valuable guide for planning intensity zones. Knowing your FTP allows you to define your training zones more precisely, improving the efficiency of each session. For instance, doing intervals in a sub-threshold zone (just below FTP) helps you work on endurance without overstraining your energy reserves.
Methods for evaluating and measuring FTP
There are several ways to measure FTP, some more accurate than others. The most traditional method is to perform a 60-minute test, during which the average power output is measured. However, for many cyclists, this test is extremely demanding and difficult to complete correctly. Therefore, other more accessible tests, such as the 20-minute test, have become popular. In this, the average power sustained over 20 minutes is calculated, and the FTP is estimated by multiplying this value by a correction factor, generally 0.95.
Another option is using cycling simulators which offer an accurate FTP estimate based on specific training sessions and tests. These platforms use algorithms that analyse your performance under different conditions and provide a constant measurement of FTP over time, allowing you to track your progress in greater detail.
The use of a power meter is essential for these tests, as only power measurements can provide an accurate FTP value. However, it is important to note that this parameter can vary slightly depending on external conditions, such as temperature or fatigue levels.
Training strategies to improve FTP
Improving FTP is no easy task and requires a planned approach that combines different types of training. One of the most effective strategies is threshold training or just below it. These sessions are typically done in intervals of 10 to 30 minutes at an intensity of about 90-100% of FTP. The aim is to accustom the body to sustaining high-effort levels for extended periods.
High-Intensity Interval Training (HIIT) also plays a crucial role in improving FTP. Short intervals at maximum intensity, followed by recovery periods, cause adaptations in both muscles and the cardiovascular system, which increase sustainable power in the long term. By alternating between threshold and HIIT sessions, you achieve the ideal combination to improve both endurance and the ability to perform intense efforts.
Consistency is key in any FTP improvement plan. Progress is not linear, and it is common to experience plateaus. However, with a well-structured training plan and the use of cycling simulators that allow you to adjust your sessions according to your fitness level, results will come.
Physiological adaptations to high-intensity training
Training to improve FTP induces a series of physiological adaptations that translate into better performance. First, mitochondrial density in the muscles increases, which improves energy efficiency during exercise. Mitochondria are the “energy factories” of cells, and a greater number of them means that the body can produce more energy with less effort.
Additionally, the cardiovascular system also adapts. The heart’s capacity to pump blood and oxygen to the muscles improves, increasing the workload capacity during prolonged efforts. The muscles’ ability to use lactate as an energy source is also enhanced, delaying the onset of fatigue.
This type of training also improves the muscles’ ability to tolerate stress, allowing you to sustain intensities close to FTP without tiring as quickly. All these adaptations are key to improving long-term performance.
The role of nutrition in FTP optimisation
A good diet is essential for improving FTP. Intense and prolonged training sessions require an adequate intake of carbohydrates, proteins, and fats. Carbohydrates are the most immediate and efficient source of energy during exercise, so they should be the main component of a cyclist’s diet who aims to improve their FTP.
Before a demanding session, it is advisable to carbo-load, ensuring your glycogen stores are full. During the session, if it lasts over an hour, it is important to replenish energy with bars, gels, or isotonic drinks to prevent early fatigue.
Hydration also plays a crucial role, as performance can be compromised if proper fluid balance is not maintained. Water and electrolyte losses during prolonged training sessions must be replaced to ensure optimal performance.
Using technology and data to improve FTP
The use of advanced technology has revolutionised how cyclists approach FTP improvement. Nowadays, power meters combined with platforms such as cycling simulators, allow for real-time, data-driven, personalised training. These systems offer structured plans that adjust to the cyclist’s fitness level and provide immediate feedback on each session.
Moreover, analysing historical data helps identify patterns of improvement or stagnation, which is crucial for adjusting training effectively. Technology also helps avoid overtraining, as you can monitor the workload and recovery time needed between intense sessions.
Cycling simulators not only serve for indoor training but also offer a virtual environment that emulates different types of terrain and weather conditions. This makes training more varied and engaging, while also allowing for the simulation of specific efforts, such as climbs or sprints.
Common mistakes in FTP training
One of the most common mistakes is training at the same intensity all the time. Many cyclists fall into the trap of constantly training near their FTP, which can lead to chronic fatigue and plateauing progress. It is important to vary intensities and alternate between hard sessions and active recovery days.
Another mistake is not paying enough attention to recovery. FTP improves not just with training but also with adequate rest. The body needs time to assimilate the training load and adapt to it. Ignoring recovery can result in overtraining and injuries.
It is also common for cyclists to underestimate the importance of proper nutrition, as mentioned earlier. Training without the necessary fuel can limit performance and the benefits of the training session.
Optimising FTP is a complex process that requires a multi-faceted approach. From proper evaluation and measurement of FTP to applying advanced training strategies, improvement in this metric is key for any cyclist aiming to compete at a higher level. Technology, nutrition, and adequate recovery also play a fundamental role in success. If you apply these strategies systematically, you will see significant improvements in your cycling performance.
