Coquart , Guillaume Boitel , Benoît Borel , Régis Matran , Claire Mounier-Vehier , Murielle Garcin The present study examined the effects of a training program at a special exercise intensity—the crossover point of substrate utilization (COP)—on the metabolic abnormalities and cardiovascular risk factors in obese women with metabolic syndrome (MetS). Eighteen postmenopausal obese women with MetS (age, 54.8 ± 8.4 years; height, 160 ± 6 cm) followed a 12-week training program consisting of three 45-minute sessions/wk on a cycle ergometer. The intensity imposed during the training sessions corresponded to COP. Before and after the training program, anthropometric, biological, and blood pressure data were collected and compared. After the training program, body mass (88.4 ± 12.3 kg vs. 85.7 ± 11.1 kg), fat mass (43.2 ± 4.8% vs. 41.8 ± 4.8% body mass), body mass index (34.3 ± 3.9 kg/m2 vs. 33.2 ± 3.6 kg/m2), and waist circumference (105 ± 10 cm vs. 100 ± 9 cm) were significantly lower (p < 0.01). Moreover, fasting plasma glucose was significantly lower after the training program (114 ± 20 mg/dL vs. 107 ± 15 mg/dL; p = 0.02) and the quantitative insulin-sensitivity check index was significantly higher (0.58 ± 0.08 vs. 0.61 ± 0.05; p = 0.05). A significant reduction in systolic ...
