GoKaleo skriver i sin serie om metabol hälsa om en liten studie som pekar på att träning ökar insulinkänsligheten efter bara en vecka. 7 av personerna hade en mild diabetes typ2 (hoppas jag översätter rätt) och 3 hade förstadie till T2.
The subjects engaged in a 7 day exercise program consisting of 50-60 minutes on a treadmill or ergometer, working at 60-70% of their maximum heart rate. On the 8th day they were given a second OGTT and exam. On the 9th day they were given a second treadmill test.
Results
VO2 max, body fat percentage and weight all remained unchanged after the 7-day exercise program, so those factors did not confound the results. There was a 36% decrease in plasma glucose, a 32% decrease in plasma insulin concentrations, and a 32% decrease in triglycerides.
What is notable here is that the subjects’ insulin response to a glucose load (from the OGTT) was significantly lower than it had been before the study. What this means: their bodies released less insulin in response to the same amount of sugar after exercising for 7 days. This is significant to the Great Sugar Narrative that holds that sugar is the driver of insulin production and release. Clearly exercise is a pertinent factor here that is ignored by the sugar-causes-diabetes contingent. Exercise can mitigate the insulin response to sugar.
