Statistics parameters explained

Here are descriptions of some parameters that can be analyzed in the Statistics view.


Effort / RPE (rating of perceived exertion)

Effort / RPE is subjective estimation of how hard the training was on Borg scale 0-10. This can be marked by the athlete or coach by sliding the slider at the appropriate position. Besides providing a value for analysis, the RPE will estimate the time spent in heart rate zones if a heart rate monitor is not used. These values can be overwritten manually if needed.

Training load

For training load we use the Trimp model with the following coefficients:
Minutes in Zone3 x coeff. 3 = Load3
Minutes in Zone2 x coeff. 2 = Load2
Minutes in Zone1 x coeff. 1 = Load3
Minutes in Zone0 x coeff. 0,25 = Load0
Training load = Load0+Load1+Load2+Load3

Even if you are using custom training zones, the load is still calculated using the 3 default zones. 

Acute load, chronic load and training stress

Acute load is the average training load of the last 7 days. Chronic load is the average training load of the last 28 days. Training stress is acute load divided by chronic load and shows how fast your load is growing. It is a good way to understand if your load is increasing too fast which might lead to overtraining and injuries.


For calory calculation we use a complex formula that uses sex, age, body weight, time spent in training zones and average heart rates of the zones.

Fatigue, muscle pain, stress, sleep problems, work/school load

These are daily metrics that the athletes can fill on a scale of 1-5 (1=very good, 5=very bad). Athletes can mark the values when logging in to their diaries. Coaches can also fill them when accessing the athletes' diaries.
