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).
文献讨论了联合训练，即在同一会话中进行更多有氧和阻力运动，是肥胖人群的一种合适策略，并且运动周期化会带来积极的健康结果；然而，联合训练的不同周期化对肥胖成年人健康结果的影响需要进一步研究。该研究的目的是描述用于比较线性周期化和非周期化联合训练对肥胖成年人健康指标和健康相关身体素质影响的方法。这是一项双盲随机对照临床试验，研究对象为20至50岁的肥胖成年人。样本将是非概率性的，参与者将被随机分配到三组之一：对照组（CG）、非周期化组（NG）和周期化组（PG）。干预将在60分钟的会话中进行，每周3天，共16周，其中1周用于熟悉训练，15周进行联合训练（在同一会话中先进行有氧运动，然后进行阻力运动）。PG组将进行三个为期5周的中周期，在整个干预过程中强度逐渐增加[有氧运动：从心率储备（HRR）的40 - 49%增加到60 - 69%；力量训练：从每组12至14次最大重复次数（MR）增加到8至10次MR]；NG组在整个研究过程中保持相同的相对强度（有氧运动：HRR的50 - 59%；力量训练：2组，每组10 - 12次MR）。CG组的参与者将保持其日常活动，不进行所提议的干预。将对生化指标、身体成分、心血管参数、心肺功能、最大上下肢力量、柔韧性以及主观健康相关参数进行干预前和干预后的评估。该项目已获得原机构的人类伦理与研究委员会批准（协议2,448,674），并在巴西临床试验注册中心（RBR - 3c7rt3）注册。
