Hi
I have been T1 for over a year now, with fairly/very good control.
On saterday I played cricket, my sugars after breakfast and throughout the morning were in the 5's but after batting for 45 minutes they were at 11.5. Why would they increase after some intense running around? i thought they would drop. normally my sugars are fairly stable after gym/ cycleing ect.
is this something to worry about or should i just keep an eye on it while doing sport.

thanks
 
In general aerobic exercise tends to lower blood glucose but anaerobic exercise can raise it. One thinks of cricket as a fairly gently exercise but in fact ( I think) you are doing a whole series of short but fast runs. 'These high intensity bursts may result in increased levels of counter-regulatory hormones and consequently increased glucose production (from the liver)'

Hi hugogj,

Short intense bursts of exercise, such as sprinting for the ball during a cricket match, are far
more likely to raise blood sugars compared to more moderate forms of exercise.

Competitive stress can also be to blame for a blood sugar rise, particularly in team sports like football, cricket and rugby.

Hi hugoji,

I suspect there were 2 reasons for the sudden change. Firstly in a competitive sport like cricket, particularly when you are batting (probably less so when fielding), your adrenalin levels would be much higher, and that can cause increased blood sugar. Secondly when you started your BS was in the 5s, so not particularly high. The energy you expended during the game will have used your reserves of stored glucose, plus what remained in your blood stream, so that your liver will have been generating glusose to compensate. It is not uncommon for people involved in sports to finish with a much higher BS level than they started with.

This website explains it far better than I can
