    No denying - "PA" as they put it is a great tool for BG control.

    But why? What happens when we exercise that makes BG control easier?

    Insulin resistance is reduced - but, how and why?

    Sugar is fuel, and when we exercise, we use it. I'd like to know more about how this happens. Off to Google - I'll be back...

    Maybe not to question the how but be glad that it works... 8)

    Possibly temperature related?

    My google search came up with glut4: seems glut4 is forced to the cell membrane upon exercise and picks up glucose on the muscle contraction. The effect persists for a short time ~24 hours and then diminishes.

    Alright... so for us that may be a bit slow after the weekend's wine - wassit all mean?
    You can overcome insulin resistance by exercise but only temporarily? It is no cure but surely even temporary relief is worthwhile?
    Is it proportional to the amount or intensity of the exercise? How soon after eating for example? No doubt its effects vary individual to individual.
    Someone please answer as this has been bugging me for a while.
    In the meanwhile I will order a takeaway then clear the drive after scoffing it down...8)

    CowboyJim, I guess it does mean there is temporary relief, like you I think that this is better than nothing! If anyone has any real answers - we are interested to hear from you!

    This video might give you some answers, also google Sheri Colberg, on her own site and more academically on pubmed there are links to lots of articles and papers about D and exercise.

    From the bit of research I have carried out it seems that resistance training (weight bearing), walking and aerobics exercises are best, it is a shame that no one runs a specific diabetes training course in any of the local gyms, I am sure there would be lots of members to join :D

    Copwboyjim asks?

    If I am over 7.8mmol/l I exercise I have a weight room in the basement.

    My suggestion is exercise all the major muscle groups with situps; pushups; bends; lunges; crunches ;etc. using your own body weight.

    I exercise for ~5min, ~ 45 min to 1hour after eating I find the drop in BG to be ~ 1 mmol/l after moderate exercise.

    [​IMG]

    The graph is a screen shot from Dr. Christiansen's presentation at the European Diabetes symposium.
    It show cgms of healthy individuals after a high carbohydrate breakfast.

    The right hand margin has been cut off for some reason so I will explain briefly.

    1 green line is c peptide
    2 yellow line is insulin
    3 bottom brown line is lower range limit of the group
    4 blue line is the mean average BG of the group
    5 pink is venous BG
    6 top brown line is upper range limit of the group

    This is what I use to maintain what was presented as the normal range of BG in healthy individuals.
    Y axis is in mg/dl to convert to mmol/l divide by 18.

    Very interesting and many thanks for taking the time.

    Once again the means exist to ameliorate if not nullify our condition. However, this recourse is not for everyone. Even I who exercise a lot balk at all the measures you talk about. We need something simpler and quicker. Fat chance I suspect.

    To me it seems a lot of effort for just 1 mmol/l. Plus it would not help my pathetic attempts to restore my weight.

    I wonder how this compares to meds. Metformin is only of limited use I believe, better to adjust your diet and do some exercise (as well).
    Cheers 8)

    Cowboy Jim, in general I think that aerobic exercise rather than weights is more likely to cause instant reductions in glucose levels.
    The results of the big blue test this yearshowed a median 1mmol/l drop with just 14 min of exercise (all types)
    Total Participants 1156
    .
    Median Blood Sugar Before 133.6 mg/dl
    .
    Median Blood Sugar After 111.6 mg/dl
    .
    Median Change -18.5 mg/dl

    Now Christmas food shopping in Tescos today dropped my glucose levels from 8.5mmol/l to 3.6mmol :lol:

    Just did a test on myself with resistance training.

    Ate 1 mince meat tart and 1 slice of Christmas cake

    45 min later 9.5mmol/l ~171mg/dl

    2 min aerobic on mini trampoline
    10 crunches with 30 lb weight
    10 bench press with 100lb weight
    10 inclined press 80 lb weight
    10 leg lifts with 80 lb weight

    retest shows 10 mmol/l ~180 mg/dl
    believe this to be the meal still digesting

    Redo exercise routine 15 min later
    retest shows 7.8mmol/l ~140mg/dl

    Total BG lowering 2.2 mmol/l ~39.6 mg/dl ;exercise time ~10 min

    I think any type of exercise helps but the harder the better if the muscle goes hypoxia ( lacking oxygen) you pick up a lot of BG very quickly if you do very moderate exercise such as walking BG is still picked up but much slower aerobic and weight training cause hypoxia both are good; together they are better.

    Genius!
    Proof at last.
    But all that effort for a couple of tarts.... 8)
    Something psychological here... punish me oh punish me for my self indulgence!
    That has great appeal.
    Maybe I will try something similar soon.

    Sorry to be thick but what do you mean by "pick up a lot of BG"?

    BG = blood glucose
    There are two ways to take blood glucose into the muscle ;glut4 is translocated to the cell membrane by insulin and it picks up glucose. The second way is muscle contraction glut4 is translocated to the cell membrane without the need of insulin and it picks up BG. The physiological response of muscle contraction translocating glut4 is not well understood but it does happen.
