Acute Load Calculation

lucky
over 1 year ago

I don't understand how acute load is calculated on Garmin Connect App and Garmin Edge 840.

During Jun 3 to Jun 5, I did indoor cycling exercise on my Garmin Edge 840, with different Exercise Load, but the Acute Load curve on Connect App keeps decreasing, even for Jun 5, far from May 28 with high exercise load value 644 for 8 days, the Acute load still decrease.

Another strange thing is that when I was finishing cycling on Jun 5, the Acute Load curve on Edge 840 was increasing, but when I opened the Connect App and found the decreased Acute Load curve on my phone, the curve on Edge 840 turned to decrease same with Connect App after I touched sync. WHY?????

    Thanks a lot, I have tried hobdell1's method, and did some calculation by excel and found the formula. The Calculated Acute Load (CAL) matches well with Acute Load (AL) before Jun 4, while Jun 4 and Jun 5 does not match. When I change the EL value of Jun 4 from 215 to 18, the CAL matches well for both date Jun 4 and Jun 5. I don't know why this happened, were there some issues with Garmin server on Jun 4?

    Before change:

    Date EL AL CAL
    6/5 33 446 671.7975
    6/4 215 523 774.18
    6/3 91 637 635.5875
    6/2 0 644 643.4925
    6/1 73 768 767.4225
    5/31 110 789 788.97
    5/30 0 749 749.3175
    5/29 0 869 869.04
    5/28 644 989 988.7625
    5/27 0 215 214.3275
    5/26 0 271 270.4275
    5/25 145 328 326.5275
    5/24 0 180 179.265
    5/23 0 218 216.8775
    5/22 0 365 363.885
    5/21 0 512 511.02
    5/20 150 659 658.155

      

    After change:

    Date EL AL CAL
    6/5 33 446 445.74
    6/4 18 523 523.005
    6/3 91 637 635.5875
    6/2 0 644 643.4925
    6/1 73 768 767.4225
    5/31 110 789 788.97
    5/30 0 749 749.3175
    5/29 0 869 869.04
    5/28 644 989 988.7625
    5/27 0 215 214.3275
    5/26 0 271 270.4275

    Try editing (without changing anything, or just a minor detail) and then saving the cycling activity from June 4th. If it does not help, try changing the type of the activity for example to running and than back to cycling. If nothing helps, contact the Support.

    Thanks a lot, I have tried all and still not helped. But I think I know what happened.

    My primary training device is forerunner 955, and the exercise load on my 955 device is 17 on June 4th. I have tried delete the June 4th active data both on my watch and Connect app then re-upload on Connect web, but the watch value does not delete or change. This 17 value is close to my 18 value in reply, if I know how to repair the watch value, the problem will be fixed.
