RESUMO

The aim of the present study was to systematize and analyze the methodological quality of physical activity interventions in leisure time in obese adults. A systematic review was conducted between June and August 2017 through four electronic databases (PubMed, Lilacs, ScienceDirect and Web of Science). A total of two researchers selected articles and, through consensus, analyzed these articles using the RE-AIM framework, which aims to identify the following dimensions: reach, effective-ness, adoption, implementation and maintenance of interventions. Of the 2,334 articles selected, nine met all eligibility criteria. The mean duration of the interventions was 14 weeks, with strategies including mainly aerobic exercises and nutritional monitoring.When the individual studies were taken into consideration, 67% reported at least one category of each dimension. The dimension with the highest reported proportion was "reach", found in 65% of the interventions. The "effectiveness", "adoption" (organizational and staff ), "implementation" and "maintenance" dimensions (individual and organizational) were reported in less than 40% of the items investigated for this information. The conclusion is that most of intervention studies reported the "reach" dimension, while only a few described "maintenance". Thus, it is suggested that future studies should previously look at the pres-entation of the total effect of the intervention and the methods applied, offering detailed information about each procedure. The scientific and practical scenario will provide relevant information about construction, application and subsequent follow-up of the interventions in leisure-time physical ac-tivity for obese adults


O objetivo do estudo foi avaliar sistematicamente a qualidade metodológica de intervenções de atividade física no lazer para adultos com obesidade. Trata-se de uma revisão sistemática conduzida de junho a agosto de 2017, com consulta eletrônica em quatro bases de dados (PubMed, Lilacs, ScienceDirect e Web of Science). Dois investigadores selecionaram os artigos e, mediante ao consenso, analisaram os artigos pelo emprego da ferramenta RE-AIM, que se propõe a identificar cinco dimensões específicas: alcance, efetividade, adoção, implementação e manutenção. Dos 2.334 artigos selecionados, nove atenderam aos critérios de elegibilidade. A duração média das intervenções foi de 14 semanas, com estratégias que continham exercícios aeróbios e acompanhamento nutricional em sua maioria. A dimensão com maior proporção de indicadores reportados foi o alcance, representada em 65% das intervenções. As dimensões de efetividade, adoção (organizacional e staff ), implementação e manutenção (individual e organizacional) foram relatadas em menos de 40% dos indicadores. Um total de 67% dos estudos relatou, no mínimo, um indicador de cada dimensão. Conclui-se que as intervenções abordam com mais profundidade o alcance, ao passo que poucas descrevem informações sobre a manutenção. Dessa forma, sugere-se que estudos futuros atentem para a apresentação do efeito total da intervenção e os métodos utilizados, ofertando informações detalhadas sobre cada passo. Assim, o cenário científico e prático contará com importantes informações sobre a construção, a aplicação e o acompanhamento a posteriori das intervenções em atividade física no lazer para adultos com obesidade

RESUMO

The literature discusses that combined training, aerobic more resistance exercises in the same session, is a suitable strategy for people with obesity and that exercise periodization leads to positive health outcomes; however, the implication of different periodizations of combined training for health outcomes in obese adults requires further investigation. The aim of the study will be to describe the methodology used to compare the effect of linear periodized and non-periodized combined training on health markers and health-related physical fitness in adults with obesity. This is a blinded randomized controlled clinical trial investigating adults with obesity in the age group 20-50 years. The sample will be non-probabilistic, and participants will be allocated randomly into one of three groups: control group (CG), non-periodized group (NG), and periodized group (PG). The intervention will occur in 60-min sessions, 3 days a week for 16 weeks, with 1 week dedicated to familiarization with the training and 15 weeks of combined training (aerobic followed by resistance in the same session). The PG group will perform three mesocycles of 5 weeks each, progressing in intensity throughout the intervention [aerobic: from 40-49% to 60-69% of heart rate reserve (HRR); strength: from 12 to 14 maximum repetitions (MR) to 8 to 10MR]; the NG group will maintain the same relative intensity throughout the study (aerobic: 50-59% of HRR; strength: 2 sets of 10-12 MR). Participants in the CG group will maintain their usual activities without the proposed intervention. Pre- and post-intervention assessments will be performed for biochemical markers, body composition, cardiovascular parameters, cardiorespiratory fitness, maximum upper and lower limb strength, flexibility, and subjective health-related parameters. This project was approved by the Committee of Ethics and Research with Human Beings of the institution of origin (protocol 2,448,674) and registered in the Brazilian Registry of Clinical Trials (RBR-3c7rt3).
