The functional threshold power (FTP) is the highest power you can sustain, in a reasonable steady state, for one hour. If you deliver more power than you cannot sustain that for one hour because of increasing fatigue. An intensity under the FTP level can easily be maintained much longer than one hour. It is the art to dose the test well. That is a learning process that takes time. You can determine your FTP in a laboratory test but it is also possible to determine the FTP test for yourself by a field test.
FIELD TEST TO DETERMINE THE FUNCTIONAL THRESHOLD POWER
The functional threshold power (FTP)
Cycling for one hour as fast as possible and as constantly as possible. The power that you providing is the FTP. Cycling for one hour as fast as possible at FTP level is a heavy effort, which is difficult to fit into the training.
That is why we opted for a shorter 20 minute test. This test is also fully driven, as in a time trial, so at the highest possible intensity. The average output power is subsequently corrected, allowing the FTP can be calculated. Allen and Coggan take a percentage of 95% of the average power for 20 minutes.
From own experience it shows 93 percent is a better percentage. During a maximum effort of 20 minutes is the intensity level above the anaerobic threshold. Hence the correction with 95 or 93%. CP20 = average power for 20 minutes.
FTP = 0.93/0.95 x CP20
The field test of 20 minutes can be carried out easily and more frequently so that the performance can be objectively monitored, and it can be determined whether the progression of the rider takes place as desired.
|Cyclist 20-minute time trial 320 Watt
Calculated FTP = 0.93 x 322 = 300 watts
| CLASSIFICATION TRAINING AREAS
7 different zones (1-7) for the training of the different energy systems:
|ZONE 1: ACTIVE RECOVERY|
| Power < 55% of the FTP.
Active recovery duration between 30 and 90 minutes.
|ZONE 2: ENDURANCE TRAINING|
| Power between 55-75% of the FTP.
Quiet duration training ranging from one to eight hours.
|ZONE 3: TEMPO - ENDURANCE TRAINING|
| Power between 75-90% of the FTP.
In this zone speed-endurance training and intensive endurance blocks.
Duration of these trainings between 15 minutes and 2 hours.
|ZONE 4: FTP TRAINING|
| Power between 90-105% of the FTP.
In this zone, the longer interval workouts are done with the aim to improve the FTP.
The interval blocks in well-trained cyclists have duration of 3 to 30 minutes.
The total duration of training in this zone amounts to 10 and 60 minutes.
|ZONE 5: VO2max TRAINING|
| Power between 105-120% of the FTP.
In this zone shorter interval blocks for improving the anaerobic capacity.
Interval blocks of 1-6 minutes to improve the VO2 max.
Total duration of training in this zone is 5 to 30 minutes.
|ZONE 6: ANAEROBIC CAPACITY TRAINING|
| Power between 120-150% of the FTP.
This training consists of very short intensive intervals that last 30 seconds to 3 minutes.
Total duration of this training between 3 and 15 minutes.
|ZONE 7: NEUROMUSCULAR POWER|
| POWER well above 150% of the FTP.
You can only see afterwards how high it was. It comes to maximum, very short and intense sprints.
From standing or running start. This training gives stress on the musculoskeletal system and less on the metabolic system.
