RESUMO:

INTRODUCTION: In the overweight population, most of the studies have used training protocols in controlled laboratory environments, with a focus on attending small groups in person, with little applicability to population groups. In this way, this study aims to disseminate training strategies carried out in open air environments that allow greater reach of people, using protocols and instruments that are accessible, effective and safe, and that match the reality of the population. OBJECTIVE: To compare the effect of continuous moderate intensity training, high intensity interval training and self-selected intensity training on body composition, cardiorespiratory fitness and adherence in overweight subjects. MATERIALS AND METHODS: Seventy-three adults (45 women and 28 males, 31.4 ± 7.2 years, 28.9 ± 2.7 kg / m 2) were randomized into three groups: continuous training of moderate intensity (TCMI; n = 24); high intensity interval training (TIAI; n = 23) and self-selected intensity training (TIA; n = 26). At the ICMT, participants were instructed to exercise at the subjective perception of effort (PSE) 13 (6-20 of the Borg scale) for 30 minutes. At HIIT, the subjects were instructed to perform 10 stimuli of 60 seconds in PSE of 15-17, interspersed with 60 seconds of active recovery. In the TIA, the participant was allowed to select the intensity for 30 minutes. The training program was conducted three times a week for four weeks in a supervised manner. The intervention was performed in a total period of 13 weeks, with 1 week of specific adaptation to the types of training (Adaptation period) and 12 weeks of training (training period). The training period had a weekly frequency of three days (Monday, Wednesday and Friday) and was divided into two phases, one supervised and one semi-supervised. Body composition was assessed by Dual Energy X-ray Absorptiometry (DEXA) technique and cardiorespiratory fitness was evaluated by ergospirometry. Adherence was calculated by the ratio between the subjects who completed the program by the total number of subjects who started the training program. STATISTICAL ANALYSIS: Descriptive data were expressed as mean and standard deviation. The generalized estimation equations (GEE) were used to verify the interaction between group x time, and group effect and time for the outcome variables. The Bonferroni post hoc was applied to identify the significant differences. Fisher exact test was used for adherence. The level of significance was set at p <0.05. RESULTS: There was no significant interaction between group x time and group effect for the components of body composition and cardiorespiratory fitness (p> 0.05). Time effects on BMI, MGG, MGT, MLG, GA, GG and GT (p <0.05) were observed, with only TIAI and TIA reducing these components. Regarding cardiorespiratory fitness, a similar increase was observed in VO2peak and VO2 in ventilatory thresholds between groups (p <0.05). There were no differences in adherence between groups (p> 0.05). CONCLUSION: Regardless of intensity, the intervention was sufficient to improve cardiorespiratory fitness. Moderate intensity exercise did not promote body composition benefits in overweight / obese adults. The three training strategies seem to be important in maintaining adherence in a 12-week exercise program.
