Training effect

Why is there a differente?

Why not? Different performance, different value. Besides that, those values are just estimates, influenced by a number of factors, that can differ from one activity to the other

What training do i have to do to increase the anaerobic training load?

I'd tell anaerobic exercises - like sprints, HIIT, weight lifting, etc. Google them out - there are thousands of examples available online

That’s the problem... those exercises - like sprints, HIIT doesn’t give a value to my anaerobic load.

Those measurements are purely based on heart rate, compared against your set heart rate zones. Those heart rate zones are set under "User Settings" for your device, and can be based on your own estimate of max heart rate, or comparing your estimate of max heart rate and the device's measurement of resting heart rate (they call it heart rate reserve), or the device's measured Lactate Threshold heart rate (this requires a few activities that pushed your heart rate high enough like running or cycling). I like the Lactate Threshold one best as it doesn't require me to guess anything, and a moderately effortful run or cycling will adjust the zones if a new Lactate Threshold heart rate is discovered.

Once the heart rate zones are set, you will get credit for anaerobic training effect in any exercise/sport that you use your device to track that pushes your heart rate into the anaerobic zone according to your heart rate zones setup. A common source of error is if your heart rate zones are set too high, you could do a pretty high effort but the device will think you're in a very moderate heart rate zone so won't give you anaerobic training effect.

Now that is a simplified explanation, details can be found at https://support.garmin.com/en-US/?faq=Vi2undejXR5Mmq662o4lO9 . This claims it is not as simple as 1-1 from a given heart rate zone to anaerobic or aerobic effect, there is a FirstBeat algorithm behind the scenes that also takes duration and other things into account but they don't say exactly what. Bottomline though, if you set your heart rate zones up properly and do any exercise, whether running or cycling or HIIT weight training that drives you heart rate high enough long enough, you will get credit for anaerobic training effect.

One last thing, make sure you don't do such exercises all the time, there is a cap to how much benefit you get from them, you need to give your body lower intensity in between.

Hope that helps.

Cheers.

Correct, they do not give value, they improve your anaerobic load, and that's the exact purpose of them.

Thank you... I think you have solved my problem. I just did an intensive training so I want to wait a week for a lactate test. In a few weeks I will let you know if heart rate %ldhs shows another value of my training plan. 

Thank you. I hope the answer from Saad wil help.
