The high flavanol group also experienced a 6.1% increase in flow-mediated dilation…which is basically a measure of a blood vessel’s ability to relax.
I only have two issues with this study. Firstly, there is no mention of the beverage’s nutritional ingredients or contents. What was the protein, carbohydrate, and fat percentages? What else was in the beverage besides cocoa flavanols?
My other concern is that the researchers used the BMI (body mass index) to determine which subjects were overweight and which were obese. The BMI has many flaws and I wonder why the researchers didn’t use more accurate methods to measure the subjects.
Anyway, with regards to study in general, I’m sure this doesn’t mean you can scoff loads of chocolates and expect to exercise with ease. Please use common sense before starting any exercise regime. Start off slowly and move at your own comfortable pace, before building up and increasing your speed and resistance over time.
