I think the proposed formula does not help us.
In the calculation of training load based on TSS, duration, NP and IF are important variables.
The author of the proposed formula only uses IF for his calculation of training load.
FTP, however is an important parameter for the calculation of IF .
FTP is the maximum effort you can maintain for an hour.
To calculate training load, the author holds on to an endurance parameter.
But he started his quest for a new calculation of training load, because he thought his sport was not an endurance sport.


When I compare TSS and IF of my own Aerobic Capacity intervals with Lactate Treshold intervals, the first workouts have a higher TSS. While the second workouts have a higher IF.
When measured over the complete workout.
The author of the proposed formula claims otherwise.


It is true that cycling at an easy pace for a long distance creates different training stresses from a shorter distance at a high intensity, and the two cannot really be equated in a usable model.
Therefore A Coggan has developed the concept of Normalized Power
Normalized power is the power you could have maintained if you would have been 100% steady in power output.
It is a rolling average for the past 30 sec (the fourth root of the 4th power average)
The 30 seconds is to compensate for the body lagging behind the effort. Given that you need to stop pedaling here and there for a turn or pothole, your body doesn't have the time to adapt to these short holes in power so your body has no physiological rest. Your average power, on the other hand takes all these stops into account which makes it flawed and a bad metric of the effort given.
IF is a measure for the intensity of this workout.
IF is a percentage of your FTP (functional treshold power)
IF= NP / FTP
Workouts with a constant heart rate at your anareobic threshold will yield a value of 1.0 (100%).
For the calculation of IF, the duration of your effort is not important.
A one minute exercise at your FTPlevel, is rewarded with IF=100
Just like an 100 minute exercise at FTPlevel.

TSS is calculated from duration, NP, IF and FTP
You get 100 TSS points for a one-hour max effort.
However, if you train at a lower effort you can still accumulate 100 TSS if your hold the lower effort for a longer period of time.

Post exercise response is the product of absolute load, exercise intensity, and exercise duration (total load)
They all have their own fitness and fatigue after effects.
A training load model should incorporate all three components.
