Verify the effect of non-periodized and linear periodized combined training on body image perception and body dissatisfaction in adults with obesity.
A randomized clinical trial on the effect of two types of combined training periodization was carried out on people with grade I and II obesity.
Participants were allocated into three groups: non-periodized periodization group, linear periodization group, and control group, with 23 participants in each.
Adults with obesity, with a body mass index between 30 kg/m² and 40 kg/m².
The intervention lasted 16 weeks (separated into three mesocycles of 4 weeks and 1 week of familiarization), in 3 weekly sessions of 1 hour each, composed of aerobic (30 min) and muscle strength exercises (six exercises) in the same session. The group with non-periodized model maintained uniform intensity, volume, and workload throughout the mesocycles. The group with the linear periodization model started with low initial intensity, subsequently introducing a gradual increase of intensity in the mesocycles.
Body image perception (current and ideal silhouette) and body dissatisfaction were assessed using the Stunkard silhouette scale.
The perception of the current silhouette increased only in the control group (Δ = 1.16; = 0.04). There was a significant reduction in the ideal silhouette over time ( = 0.001), especially in non-periodized group (Δ = -1.26). Body dissatisfaction increased significantly only over time ( = 0.001), especially for control group (Δ = 1.47).
Regardless of periodization, combined training effectively maintained the perception of the current silhouette and reduced the ideal silhouette in adults with obesity.

验证非周期性和线性周期性联合训练对肥胖成年人身体意象感知和身体不满的影响。
对 I 级和 II 级肥胖者进行了两种联合训练周期性的随机临床试验。
参与者被分配到三个组：非周期性周期性组、线性周期性组和对照组，每组 23 人。
肥胖成年人，体重指数在 30kg/m²到 40kg/m²之间。
干预持续 16 周（分为三个 4 周的中周期和 1 周的熟悉期），每周 3 次，每次 1 小时，包括有氧运动（30 分钟）和肌肉力量练习（6 项练习）在同一次会议上。非周期性模型组在整个中周期保持均匀的强度、容量和工作量。线性周期性模型组在中周期开始时强度较低，随后逐渐增加强度。
使用 Stunkard 剪影量表评估身体意象感知（当前和理想剪影）和身体不满。
只有对照组的当前剪影感知增加（Δ=1.16；=0.04）。随着时间的推移，理想剪影显著减少（=0.001），尤其是在非周期性组（Δ=-1.26）。随着时间的推移，身体不满显著增加（=0.001），尤其是对照组（Δ=1.47）。
无论周期性如何，联合训练都能有效地保持肥胖成年人对当前剪影的感知，并降低对理想剪影的感知。
