Effect of combined training on ratings of perceived exertion and sensation of pleasure/displeasure in obese women

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.

摘要 肥胖人群在步行与抗阻训练中自主选择的运动强度，未达到改善健康相关结局的推荐标准。有鉴于此，可将有氧训练与抗阻训练整合至单次训练课中，以期在维持积极情绪反应的同时，提升训练总量并优化生理适应效果。迄今为止，尚无研究针对肥胖女性在联合训练课中的自觉劳累分级（ratings of perceived exertion, RPE）与愉悦/不愉悦感受（sensations of pleasure/displeasure, SPD）进行评估。本研究旨在：(1) 评估肥胖女性在联合训练课中的RPE与SPD水平；(2) 对比不同抗阻训练动作中的RPE与SPD反应。招募12名久坐不动的肥胖女性（年龄：39.2±11.1岁；身高：160.4±5.9cm；体质量：87.4±5.8kg；体质量指数（BMI）：33.6±1.2kg·m⁻²），令其完成一次有氧与抗阻联合训练课。训练期间记录受试者的RPE与SPD数据，采用单因素重复测量方差分析（One-way repeated measures ANOVA）与邦费罗尼（Bonferroni）事后检验进行统计分析。结果显示，尽管训练总量有所提升，受试者的自觉劳累分级仍处于较低水平，情绪反应亦呈积极状态。不同抗阻训练动作间的RPE与SPD水平无显著差异。由于联合有氧与抗阻训练可带来较低的自觉劳累程度与积极情绪反应，因此可在训练计划的初始阶段采用该训练模式。
