Insulin response of women athletes in relation to body fat quantified by magnetic resonance imaging.
We report the glucose and insulin response to a 300-min glucose tolerance test among 17 women athletes as compared with 11 normal, nonatheletic controls. Also reported is the relationship of the insulin area under the curve as a function of percentages of total fat (TF), subcutaneous fat, and internal fat of total volume (TV) quantified by magnetic resonance imaging overall and at six regional sites. Athletes had a more sensitive insulin response to the glucose tolerance test as compared with controls. The insulin area under the curve of athletes and controls was significantly (p = 0.05) related to their overall TF/TV%; athletes had significantly less TF/TV% compared with the controls.
