Attenuated Insulin Response Around Workout?

Would an attenuated glucose and insulin response to a carb load be desirable either peri or post-workout when, presumably, you want increased glucose and insulin levels?

The reason I’m asking this is because of an article on the American Diabetes Association website which relates a study showing apple cider venegar to be effective in lowering glucose and insulin in response to a sucrose or starch load.“Interestingly, an early report showed that vinegar attenuated the glucose and insulin responses to a sucrose or starch load (1).”

They should try other types of vinegar. Perhaps the English have the right idea putting it on everything.
