A Study on the Effects of Zumba Combined with Resistance Training on Body Morphology and Physical Self-Esteem in Adolescents with Obesity

INTERVENTION: Zumba Combined with Resistance Training:The experimental group will receive a 4‐week Zumba combined with resistance training intervention, with 6 training sessions per week and approximately 90 minutes per session. Each session will follow the sequence of "warm‐up–resistance training–transition rest–Zumba training–cool‐down," including a 10‐minute warm‐up, 30 minutes of resistance training, a 5‐minute transition rest, approximately 40 minutes of Zumba training, and a 5‐minute cool‐down. The warm‐up will consist of dynamic exercises, mainly including marching in place, high knees, shoulder circles, trunk rotations, lateral trunk flexion, hip swings, knee joint movements, side‐to‐side movements, and step touches, with the aim of activating the major muscle groups of the whole body. Resistance training will use body weight, resistance bands, and light dumbbells weighing 1.5–2.0 kg. The main exercises will include squats, kneeling push‐ups, quadruped contralateral arm and leg extensions, prone scapular stabilization exercises (Y–W), and glute bridges. Each exercise will be performed for 3 sets, with the number of repetitions and external resistance progressively increased over the intervention period. During Week 1, body‐weight exercises will be used primarily; resistance bands will be introduced in Week 2; 1.5‐kg dumbbells will be used in Week 3; and the load will be further increased to 2.0‐kg dumbbells in Week 4. The Zumba training will mainly consist of four basic dance styles: Merengue, Salsa, Cumbia, and Reggaeton. The principal movements will include March, Step Touch, 2 Step, 6‐Count Side‐to‐Side, Beto Shuffle, Bo XStep Half Tempo, V‐Step, Right & Left, Front & Back, Rock Back, Hip Rolls, Turn in a Circle, Right/Left Front Kick, Cross Step, Sugar Cane Machete, Stamp CONDITION: Body Morphology and Physical Self‐Esteem PRIMARY OUTCOME: Children and Adolescents’ Physical Self‐Perception Profile Score;Implicit Physical Self‐Esteem;Body Mass Index;Body Fat Percentage ;Lean Body Mass;Skeletal Muscle Mass;Waist Circumference ;Hip Circumference;Thigh Circumference;Chest Circumference ;Waist‐to‐Hip Ratio (WHR); SECONDARY OUTCOME: Waist‐to‐Height Ratio;Hip‐to‐Height Ratio;Thigh‐to‐Height Ratio ; INCLUSION CRITERIA: 1.Aged 13–15 years; 2.Meeting the diagnostic criteria for obesity in children and adolescents; 3.Having no severe cardiovascular, visceral, or musculoskeletal diseases, or other contraindications to exercise; 4.Being able to complete the prescribed exercise intervention and related assessments; 5.Voluntarily participating in the study, with written informed consent obtained from both the participant and their legal guardian.
