Exercise training at the crossover point improves bodily and cardiorespiratory data but not quality of life in women with metabolic syndrome.

Abstract : This study investigated the effects of an exercise program at the intensity corresponding to the crossover point of substrate utilization (COP) on anthropometric measures, health-related quality of life (HRQoL) and cardiorespiratory fitness (i.e., peak oxygen uptake: VO2peak and peak power output: Ppeak) in women with metabolic syndrome (MetS). Nineteen obese and post-menopausal women with MetS (age: 54.8 ± 8.1 y, body mass: 89.0 ± 12.2 kg, body mass index: 34.5 ± 4.0 kg.m-2) followed a 12-week program consisting of three 45-min sessions per week of cycle ergometer exercise. The imposed exercise intensity corresponded to COP. Before and after the program, HRQoL, VO2peak and Ppeak were measured and then compared. Body mass (89.0 ± 12.2 vs 86.2 ± 11.0 kg), body mass index (34.5 ± 4.0 vs 33.4 ± 3.6 kg.m-2), waist (106 ± 10 vs 100 ± 9 cm) and hip (117 ± 11 vs 114 ± 11 cm) circumferences, waist-to-hip ratio (0.91 ± 0.07 vs 0.88 ± 0.07), fat mass (43.3 ± 4.6 vs 41.9 ± 4.6%), fat-free mass (56.7 ± 4.6 vs 58.2 ± 4.6%), VO2peak (16.6 ± 3.4 vs 18.1 ± 4.1 mL.min-1.kg-1) and Ppeak (102 ± 22 vs 125 ± 27 W) were significantly improved after the exercise program (P < 0.05), but HRQoL showed no significant improvement on any subscale (i.e., physical functioning: performance limitation for physical activities including bathing and dressing, role physical: problems with work or other daily activities, bodily pain, general health, vitality, social functioning, role emotional and mental health; P > 0.05). Although a 12-week exercise program at COP improved anthropometric measures and cardiorespiratory fitness in women with MetS, self-perceived HRQoL did not significantly improve. This finding may be linked to a significant but nevertheless insufficient reduction in body mass, probably because COP is too weak exercise intensity to induce important energy expenditure.
