EFFECT OF FUNCTIONAL TRAINING ON ADOLESCENT HEALTH

ABSTRACT Introduction The high rate of obesity caused by the modern sedentary lifestyle associated with bad eating habits and the high intellectual demand at school generates a physical and psychological deficit in contemporary youth. The damage caused in this growth phase is irrecoverable, and the habits acquired during this period are crucial to individual health. The urgency of this problem has generated research on methods to reverse this situation, among them functional training. Objective To study the effect of functional training on adolescent health. Methods 30 boys and 30 girls were recruited as study subjects. The experiment lasted one semester, including two weekly physical education classes focused on functional training. Data on body indexes, fitness, and physical test results were collected before and after the intervention. The results of the experiment were integrated and compared. Results The selection of functional training can optimize adolescents’ biochemical indexes, making adolescents’ orthostatic posture more balanced, and significantly improve muscle strength, body flexibility, explosive strength of upper and lower extremities, motor coordination, body flexibility, muscular endurance, cardiopulmonary function, etc. Conclusion Functional training can effectively improve the physical health of adolescents. Participants have increased their interest in sports, and this intervention can potentially promote the development of adolescents’ physical and mental health if replicated nationwide. Studies are needed to popularize functional training in adolescents. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.摘要 引言 伴随不良饮食习惯的现代久坐生活方式，加之校内高强度的学业脑力负荷，共同推高了当代青少年的肥胖率，并引发躯体与心理层面的机能缺损。此成长关键阶段所造成的损伤难以逆转，且该时期养成的行为习惯对个体终身健康至关重要。该问题的紧迫性推动了诸多旨在逆转此类状况的干预方法研究，功能性训练（functional training）便是其中之一。 研究目的 探讨功能性训练对青少年健康的影响。 研究方法 本研究招募30名男性青少年与30名女性青少年作为受试对象。实验周期为一学期，每周开设两节以功能性训练为核心的体育课。分别于干预实施前后收集受试者的躯体指标、体能水平与体育测试结果数据，随后整合全部实验结果并开展对比分析。 研究结果 采用功能性训练可优化青少年的生化指标，改善其直立姿势平衡能力，并显著提升肌肉力量、躯体柔韧性、上下肢爆发力、运动协调性、肌肉耐力与心肺功能等多项体能表现。 研究结论 功能性训练可有效改善青少年的躯体健康水平；受试对象对体育运动的兴趣显著提升，若在全国范围内推广该干预方案，有望促进青少年的身心健康协同发展。后续需开展相关研究以推动功能性训练在青少年群体中的普及。 证据等级：II级；治疗性研究——治疗效果评估类研究。
