O efeito do treinamento combinado sobre a percepção subjetiva do esforço e sensação de prazer/desprazer em mulheres obesas

Abstract

Self-selected intensities during walking and resistances training by obese subjects are below recommended guidelines to improve health-related outcomes. From this perspective, there is the possibility of combining both aerobic and resistance training in a single exercise session with the purpose of increasing training volume and optimizing physiological adaptations, while preserving positive affective responses. Until now, no study has assessed ratings of perceived exertion (RPE) and sensations of pleasure/displeasure (SPD) during a combined training session in obese women. The present study aimed to: (1) assess RPE and SPD during a combined training session in obese women; and (2) compare RPE and SPD responses during different resistance training exercises. Twelve sedentary obese women (age: 39.2 ±11.1 years; height: 160.4 ± 5.9 cm; body mass: 87.4 ± 5.8 kg; BMI: 33.6 ±1.2 kg.m-2) performed a combined aerobic and resistance training session. RPE and SPD were recorded during the session. Data were analyzed with One-way repeated measures ANOVA and Bonferroni’s post hoc tests. The results revealed that, despite the increase in exercise volume, RPE responses were low and affective responses were positive. There were no significant differences in RPE and SPD values among resistance exercises. Combined aerobic and resistance training can be prescribed during the initial phase of a training program because it produces low perceived exertion and positive affective responses.
