The basal energy expenditure of female athletes vs. sedentary women as related to their family history of type 2 diabetes

subject

description

The purpose of this study was to investigate the basal metabolic rate (BMR) in 16 professional sportswomen (soccer players) versus 15 sedentary women, as related to the presence (FH+) or absence (FH-) of a family history of type 2 diabetes. The sportswomen, in toto, had a significantly higher BMR than expected from predictive equations (+14.92%). However, the difference was limited only to FH- sportswomen (+18.66%, p<0.0005). FH- sportswomen showed a significantly higher measured BMR than FH+ sportswomen (p<0.005), and FH+ (p=0.058) and than FH- (p<0.05) sedentary women. There were no other significant differences relative to physical, metabolic and plasmatic data between the groups. The sportswomen with familiarity to type 2 diabetes had a BMR lower than that of FH- sportswomen, and similar to that of sedentary sedentary women. It appears that FH+ sportswomen have a "sub-clinical metabolic inertia", representing a precocious signal in young diabetes-prone subjects, despite the modifications induced from activity on their body composition (increased FFM, even though marginally significant).
