Anaerobic not picking up

On the last couple of runs i did with Garmin G1 software version 8.65 paired with a garmin hrm pro, my anaerobic stays on 0.0. no matter how fast and hard i train to get my hart rate up. Is there a fix for this.

Could you share a weblink to the activity? Wrongly set HR Zones or Lactate Threshold may be some of the reasons. Did you you already conduct the "Guided Lactate Threshold Test"? If not, look it up in the manual and do it.
