The relationship between leanness as measured by BMI and insulin sensitivity is well known and documented. This study used healthy young men, not obese middle-aged females.
Objectives The study goals were to: 1) define the relationship between body mass index (BMI) and insulin resistance in 314 nondiabetic, normotensive, healthy volunteers; and 2) determine the relationship between each of these two variables and coronary heart disease (CHD) risk factors.
Results The BMI and the SSPG concentration were significantly related (r = 0.465, p < 0.001). The BMI and SSPG were both independently associated with each of the nine risk factors. In multiple regression analysis, SSPG concentration added modest to substantial power to BMI with regard to the prediction of DBP, HDL cholesterol and TG concentrations, and the glucose and insulin responses

Americansweden responded to you correctly already, but I just wanted to make it very clear that “healthy” simply means without significant disease. It does NOT describe a “6-7day a week training bodybuilder who eats with the specific goal of becoming as muscular as possible”.
Not to mention BMI is very bad to use in a discussion about bodybuilding considering it does NOT take BODY FAT into consideration and most sedentary “healthy” people are not muscular at higher BMI’s.

I’m well aware of it’s limitations but for populations - not dividuals - it’s a good proxy for body fat.
My point, however, wasn’t to debate the merits of BMI, but instead to show those that are interested that the relationship between body fat and insulin resistance is well known and understood.[/quote]
I understood that but I don’t think that study (from the parts you have provided) sheds light on the issue. Maybe if the study showed people who claimed to be bodybuilders? “Healthy” people and bodybuilders (self-proclaimed or pro) probably have a significantly different levels of fat and bmi. The r2 doesn’t show a significant connection to body fat it shows it to bmi. Your extension of BMI alters what the study is and what it shows.[/quote]
Very well said.
There are very few studies done on people with our goals in particular, especially the goals of someone with very extreme physique goals who trains regularly.
Yes, EXERCISE has a hell of a lot to do with your state of health and being…therefore, ignoring that to only focus on “healthy” people is not the way to explore more about the specific effects of BODYBUILDING and BODY FAT LEVELS and the direct correlation to “insulin resistance”.
