Intensity
reference points
- Aerobic
Threshold (AeT) (3 - 4 RPE)
- Measured with drops of
blood.
- When lactate reaches 2mmol/L
(0 RPE = 1mmol/L)
- Measured in a lab with CO2
- At around 65% of max heart
rate.
- Anaerobic
Threshold (AnT) (7 RPE)
- lactate threshold (AnT measured using gas, lactate
threshold mesaure using blood.

- When lactate reaches 4mmol/L
- At this level, the bod
cannot evacuate the lactate as fast as it is produced. As a result,
lactate starts to accumulate in the muscles and restricts muscle
contraction. As a result, you suffer more and cannot maintain this
intensity very long.
- Aerobic
Capacity (AeC) (9 RPE)
- Functional
Threshold (FT)
- = Value for a 1h time trial
(note: AnT corresponds to an intensity you can maintain on a 1h time
trial
FTHR = Heart rate for a 1h time trial
FTPa = Pace (swim/run) for a 1h time trial
FTPo = Power (cycling) for a 1h time trial
- Can be measure with a 20min
test.
Training
zones
Swim: 1000m time trial
Cycling: 20min test. Ensure the
course is flat (<3%), there are no traffic lights, as sage as possible (wide
bike lane, light traffic, no intersections) and you can come to the course
later. All tests in the season must be performed on the same course to ensure
consistency.
Running: 20min test. Tracks is
ideal as it is flat and safe.
All:
- Warm up before (20min build
up intensity + 2min low RPE)
- Must be performed on a day
you are well rested (in a rest and recovery period)
- Start at a rather easy pace
and decide whether to increase the pace or not every 5 minutes or so
