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，以及校园内高强度的智力学业需求，导致当代青年肥胖率居高不下，并使其身心出现机能缺损。此成长阶段所造成的损伤无法逆转，且该阶段养成的行为习惯对个体健康至关重要。该问题的紧迫性促使学界探索逆转此类状况的方法，功能性训练（functional training）便是其中之一。

研究目的 探究功能性训练对青少年健康的影响。

研究方法 招募30名男性青少年与30名女性青少年作为研究对象。实验周期为一学期，课程包含每周两节以功能性训练为核心的体育课。于干预前后采集受试者的身体指标、体能水平及体育测试结果数据，并对实验结果进行整合与对比分析。

研究结果 实施功能性训练可优化青少年的生化指标，使受试者的直立姿态更趋平衡，同时显著提升肌肉力量、身体柔韧性、上下肢爆发力、运动协调性、身体柔韧性、肌肉耐力与心肺功能等多项体能表现。

结论 功能性训练可有效改善青少年的身体健康状况。受试者对体育运动的兴趣有所提升，若将该干预方案在全国范围内推广，或可有效促进青少年的身心健康发展。当前仍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——治疗结局探究。
