Effect of 12 Weeks of Periodized Resistance Training Upon Total Plasma Adiponectin Concentration in Healthy Young Men.
The effects of resistance training on adiponectin have thus far yielded equivocal results. However, the effect of periodized resistance training on plasma adiponectin in offspring of type 2 diabetic and nondiabetic (ND) parents (first-degree family history) has yet to be determined. Untrained healthy young men with and without a first-degree family history of type 2 diabetes were assigned to an exercise intervention group (E) or an active control group (C). The E group performed a 12-week periodized resistance training program, whereas the C group did not participate in any structured exercise program. Fasting plasma samples were obtained pre- and posttraining. Total plasma adiponectin changed significantly in the E group (33.7 ± 14.7%, p = 0.025) but not in the C group (10.8 ± 19.2%). Offspring of type 2 diabetic parents subjects had significantly greater improvements in plasma adiponectin (69.3 ± 34.8%) compared with ND subjects (-3.2 ± 29.9%, p = 0.046). Regular aerobic exercise was significantly correlated with average plasma adiponectin (r = 0.32), whereas first-degree family history of type 2 diabetes (r = -0.58) and decreases in body fat percentage (r = -0.77) were inversely correlated with average plasma adiponectin. Periodized high-intensity resistance training seems to increase plasma adiponectin, particularly in individuals with a first-degree family history of type 2 diabetes or those who experience a significant loss of fat mass. The direct correlation between regular aerobic exercise and adiponectin further suggests that a combination of aerobic and resistance training yields greater improvements in plasma adiponectin compared with resistance training alone.
