本文为探讨Thera-band渐进式训练系统对青少年健康体适能的影响，对50名青少年采用Thera-band训练系统进行练习，通过为期3个月的科学训练，对训练前后进行身体形态指标、身体机能指标、素质指标测试。结果：受试者训练后身体形态指标皮脂%、肌肉含量、大臂后侧和背部皮脂厚度实验前后存在显著性差异，对BMI值影响不大；身体机能指标静态心率、肺活量实验前后存在显著性差异，血压并没有很大变化；素质指标肌肉力量、平衡性实验前后存在显著性差异。%Objective: to investigate the effect of Thera-band training system on adolescent health and fitness. Methods: to practice 50 adolescents with Thera-band training system, through a period of 3 months of scientific training, before and after the training, body shape, body function index, quality index were tested. Results: subjects after training exist significant differences before and after the body shape index sebum% , muscle content, arm posterior and dorsal skinfold thickness experimental, the BMI value has little effect; the indexes of physical function in resting heart rate and vital capacity before and after the experiment exist significant differences, blood pressure has no great changes; quality indicators of muscle strength, balance of before and after the experiment exist significant differences.
