Workout Load Differences, need help

Former Member over 5 years ago

Last week I conducted an indoor cycle interval workout. Total duration was 45 min. Workout load was 138. This week I did the same indoor cycle interval workout with an increased time of 55min, including an additional zone 4 intensity interval. Workout load was rated at 115. How could the workout load have gone down if the intensity and duration was greater than last time? Any help is appreciated.

What was your average heart rate then and now?

Then 150 (rated tempo)/ now 141 (rated threshold)-

- I think you found the difference. I guess my next question is: isnt threshold rated higher than tempo?

What's in a name? The fact that your heart rate was lower for the same workout suggests an improvement in cardiorespiratory fitness. That's very simplistic of course as there are many other factors to take into account like the duration of any rest/recovery intervals and their intensity.

Average heart rate was 9 beats lower. There's your answer as to why load went down.

Why your HR went down? Maybe you're fitter. Maybe conditions were cooler, your fan was aimed better, etc.

That could mean that your HR data is wrong to start with leading to an incorrect training load calculation. What do you use to capture HR?
