Effects of a 12-week Equipment-based Pilates Training on Physical Fitness, Cardiovascular Function, and Vascular Endothelial Function in Middle-aged Obese Women

Abstract

PURPOSE This study aims to investigate the effects of a 12-week equipment-based Pilates training on physical fitness, cardiovascular function, and vascular endothelial function in obese middle-aged women. METHODS Twenty-four women, aged 30-40 years with a body mass index ≥ 25 and percent body fat ≥ 30% were randomly assigned to one of two groups: the Pilates training group (TR; n=12); and control group (CON; n=12). The TR participants underwent three 50-minute equipmentbased Pilates training sessions per week for 12 weeks. Participants in the CON maintained their normal life patterns for the same intervention period. Variables regarding physical fitness, cardiovascular function, and vascular endothelial function were measured and compared pre-test and post-test u a two-way ANOVA with repeated measures. RESULTS The main results of the study were as follows: 1) Regarding physique and body composition, participants’ body weight, body mass index, fat mass, percent body fat, waist circumference, hip circumference, and waist-to-hip ratio decreased significantly in the TR. 2) Regarding physical fitness, muscle strength, muscular endurance, flexibility, and cardiorespiratory endurance increased significantly in the TR. 3) Regarding cardiovascular response, SV increased significantly in the TR. 4) Regarding vascular endothelial function, blood vessel diameter at rest and during vasodilation as well as blood flow volume during vasodilation decreased significantly in the CON, resulting in a significant interaction between group and test in FMD percentage. CONCLUSIONS It was concluded that the 12-week equipment-based Pilates program improved the physical fitness and vascular endothelial function in obese middle-aged women.
