About this calculator
FTP, or Functional Threshold Power, is a key measure in cycling that reflects a cyclist's ability to maintain a high power output over a prolonged period. It is calculated based on the average power a cyclist can maintain for about 20 minutes. FTP serves as a crucial parameter for assessing a cyclist's fitness and performance.
The FTP calculator works by taking the average power that the cyclist can maintain during 20 minutes. The obtained value is considered as 95% of the maximum power that the cyclist can sustain over this period. This means that FTP is slightly below the maximum power but still represents an extremely high and constant effort.
FTP is useful in various contexts, such as in cycling training, where it helps define training zones and monitor athlete progress. It is also important in competitions, where knowing FTP can help plan the race strategy. However, care must be taken when performing the FTP test, as it requires maximum and sustained effort, which can be exhausting and requires adequate preparation.
It is essential to perform the FTP test under proper conditions and with professional supervision, especially for beginner athletes or those returning to training after a period of inactivity. Additionally, FTP can vary over time due to changes in physical conditioning, making it necessary to conduct periodic tests.
