Abstract

Objective Evidence suggests that SHBG affects glycemic control, predicts both T2D and metabolic syndrome, and is low in obese subjects. We sought to determine if resistance exercise training (RT) can increase sex hormone-binding globulin (SHBG) and ameliorate levels of related steroid hormones in overweight/obese, sedentary young men.Materials/methods 36 participants (BMI 31.4 kg/m(2), age 22 years) were randomized into an RT (12 weeks of training, 3/week) or control group (C, 12 weeks no training), and assessed for changes in SHBG, cortisol, testosterone, free testosterone (FT) and free androgen index (FAI). In addition, body composition and oral glucose tolerance testing was performed.Results 12 weeks of RT increased SHBG (P=0.01) and decreased FAI (P<0.05) and cortisol (P<0.05) compared to C. FT decreased in RT (P=0.01). Total testosterone did not change in either group. These changes were noted without weight loss, and in concert with increases in lean body mass (P=0.0002 vs C) and decreases in glucose area under the curve (AUC) (P=0.004), insulin AUC (P=0.03), and total (P=0.002) and trunk (P=0.003) fat mass in RT.Conclusion In overweight/obese young men, RT increases SHBG and lowers FAI in obese young adult men.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
