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.

Highlights

Obesity is considered a chronic non-communicable disease (CNCD), since it predisposes individuals to the development of hypertension, type II diabetes, dyslipidemia, among other disorders[1]
Self-selected intensity combined training was effective in maintaining low ratings of perceived exertion (RPE) levels and pleasurable sensations for sixty minutes
This result has an important practical application according to the hedonic theory that reports that individuals experiencing pleasant sensations regardless of what they are tend to reproduce this condition

Summary

Introduction

Obesity is considered a chronic non-communicable disease (CNCD), since it predisposes individuals to the development of hypertension, type II diabetes, dyslipidemia, among other disorders[1]. The recommendation for beginners to achieve beneficial organic modifications is to practice aerobic exercises at intensities of 60-85% of VO2max or resistance exercises at 60% -70% of 1RM These intensities provide benefits, they promote high ratings of perceived exertion (RPE), modulating the sensation to displeasure in a large part of individuals, generating a negative record of the situation[7,10]. This displeasure sensation associated with lower motivation levels and reduced self-efficacy observed in obese individuals significantly contribute to the high dropout rates of physical exercise programs[11]. A method that takes into account individual preferences in the prescription of exercise intensity has been used, known as self-selected intensity[12]
