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.

Objective To investigate the association between different domains (leisure, work, commuting, and household) of physical activity, independent and cumulative, and excess weight and obesity in Brazilian adults. Methods This is a cross-sectional survey, conducted in 2015, through telephone interviews with a representative sample of adults from the capitals of Brazil. Physical inactivity was defined as non-participation in predefined physical activities for each assessed domain. Excess weight (Body Mass Index?25kg/m2) and obesity (Body Mass Index?30kg/m2) were determined from self-reported measurements of weight and height. A binary logistic regression was conducted after adjusting for sociodemographic factors. Results Among 54,174 subjects, physical inactivity in commuting (ORexcess weight=1.27, 95%CI=1.13,1.42 and ORobesity=1.25, 95%CI=1.06,1.47) and leisure (ORexcess weight=1.12, 95%CI=1.04,1.22 and ORobesity=1.30, 95%CI=1.17,1.45) domains were associated with nutritional status. In addition, a linear trend was observed between increasing obesity and cumulative physical inactivity of all four domains (p<0.001). Conclusion Cumulative physical inactivity, especially in the commuting and leisure domains, was associated with excess weight and obesity in adults living in the capitals of Brazil. One possible explanation of these findings is that these domains involve particularly longer duration and greater intensity of physical inactivity. Public policies concerning physical activity should prioritize actions focused in promoting physical activity on commuting and leisure-time to help prevent overweight and obesity in the Brazilian adult population.

Resumo Objetivou-se verificar a associação entre a prática de atividade física em diferentes domínios e o uso de insulina em adultos e idosos. Trata-se de um estudo transversal de base populacional com dados do inquérito Vigilância de fatores de risco e proteção para doenças crônicas por Inquérito Telefônico (VIGITEL 2013). A amostra foi composta por indivíduos com idade ≥18 anos, residentes nas 27 capitais do Brasil e com diagnóstico de diabetes. A prática de atividade física no deslocamento, domicílio, lazer e trabalho, e o uso de insulina foram por autorrelato. Empregou-se regressão logística binária em análises bruta e ajustada para fatores sociodemográficos. Dos 4.593 indivíduos com diabetes, uso de insulina foi relatado por 16,2% e 25,5% dos adultos e idosos, respectivamente. A prática de atividade física no domicílio (RO: 0,61; IC95%: 0,40; 0,94) no trabalho (RO: 0,38; IC95%: 0,18; 0,78) estiveram associadas ao menor uso de insulina em idosos. Houve tendência de redução do uso de insulina à medida que se aumentou a quantidade de domínios fisicamente ativos em idosos (p = 0,003). Conclui-se que, em idosos, a atividade física praticada de forma isolada ou de forma acumulada em diferentes domínios teve associação com o menor uso de insulina.

Background: Combined exercise training has proven effective in preventing and treating sleep disorders among obese adults. However, structured progression of intensity in sleep parameters remains poorly investigated within this population. Purpose: To verify the effects of non-periodized and linear periodization combined training on the sleep quality of obese adults. Methods: This was a randomized controlled trial involving adults with body mass index ≥ 30 kg/m2, allocated to 3 groups: control (CG; n = 13), non-periodized training (NG; n = 9), and with linear periodization (PG; n = 13). Groups PG and NG trained for 16 weeks in 3 weekly sessions lasting of 60 minutes. The NG trained in 50–59% heart rate reserve (HRR) e 2 × 10–12 repetition maximum (RM) and the PG with progression in 3 mesocycles: 40–49%;50–59%; 60–69% HRR e 2x12-14; 2x10-12; 2 × 8–10 RM, with the total volume equated. Sleep quality was evaluated by the Pittsburgh Sleep Quality Index. For statistics, we used Generalized Estimation Equations considering p ≤ 0.05. Results: Sleep latency was reduced in both training groups after intervention (NG-Δ = −25.56 minutes p = .028; PG-Δ = −22.23 minutes p = .035), while significant improvements in sleep efficiency were found only in the NG (Δ = 20.67%; p = .042). Conclusion: Despite the NG’s apparent superiority, which model has the best sleep effects on obese adults cannot be stated. Hence, caution is needed while extrapolating the results.
