Adherence to a high protein and low fat energy‐restricted diet while participating in a circuit resistance‐exercise program promotes positive changes in blood glucose and lipids in postmenopausal women

Abstract

41 sedentary women (55.6±10 yr, 45.0±4% body fat, 33.7±5 kg/m2) were randomized to participate in a control group (C) or the Curves Complete® (CC) weight loss and circuit resistance‐exercise program for 12‐wks. Participants in the CC program followed an energy‐restricted diet (30% C, 45% P, and 25% F) while participating in a circuit resistance‐training (3 d/wk) and walking (30 min, 3/d wk) program. Fasting blood samples were obtained at 0, 4, 8, & 12 wks and analyzed by MANOVA. Data are presented as changes from baseline after 4, 8, and 12 wks for the C and CC groups, respectively. Overall MANOVA analysis revealed a significant time (p=0.004) and group × time (p=0.002) differences. Univariate analysis revealed significant time effects for TG, CHL, and LDL and that participants in the CC group experienced significantly different changes in blood glucose (C 1.7±8, 2.6±6, −1.3±8; CC 0.6±8, −3.2±6, −0.8±7 %, p=0.04) and CHL (C 0.6±12, −0.3±12, −2.2±11; CC −11.2±11, −9.5±10, −11.2±9 %, p=0.005) with no significant differences in TG (p=0.14), HDLc (p=0.37) or LDLc (p=0.11). Results indicate that adherence to a high protein and low fat energy restricted diet while participating in a resistance‐based circuit training program promotes favorable changes in blood glucose and some blood lipids in postmenopausal women.
