Abstract:
Based on a 12-week experimental intervention, this study examines the impact of an “athletic ability + sport-skill” integrated model on adolescents’ physical fitness. Participants were Grade-8 and Grade-11 students who received two types of interventions: “athletic ability + group rope-skipping” for junior-high groups and “basketball - specific + fancy rope-skipping” for senior-high groups. Exercise intensity was uniformly controlled at 120-140 bpm, three 30-min sessions per week. Results showed significant improvements among junior-high boys in body mass, skinfold thickness, vital capacity, hand-grip strength, pull-ups, endurance running, reaction time and balance; junior-high girls improved markedly in body mass, skinfold thickness, hand-grip strength, endurance running and balance. Senior-high boys exhibited pronounced gains in body mass, upper-arm skinfold thickness, vital capacity, explosive power, speed-endurance and balance, whereas senior-high school girls improved significantly in body mass, skinfold thickness at multiple sites, cardiorespiratory fitness and hand-grip strength. The study confirms that structured exercise interventions exert positive effects on middle-school students regardless of grade level or sex. It is recommended that “athletic ability + sport-skill” integrated teaching be promoted in primary and secondary physical education, with differentiated designs for grade and genders, and advance the systematic and scientific development of physical health interventions.
本文通过为期12周的实验干预研究,探讨“体能+技能”融合模式对青少年体质健康的影响。研究对象为初中与高中二年级学生,分别开展“体能+多人跳绳”与“篮球专项+花样跳绳”两类干预,运动强度统一控制在心率120~140次/分钟,每周3次、每次30分钟。结果表明,初中男生在体重、皮脂厚度、肺活量、握力、引体向上、耐力跑、反应时和平衡能力等指标上均有显著提升;初中女生在体重、皮脂厚度、握力、耐力跑和平衡能力方面改善明显。高中男生在体重控制、上臂皮脂厚度、肺活量、爆发力、速度耐力及平衡能力方面均取得显著进步;高中女生在体重、多部位皮脂厚度、心肺功能和握力等指标上提升尤为突出。研究证实,结构化运动干预对不同学段、性别的中学生体质健康均具有积极作用,建议在中小学体育教学中推广“体能+技能”融合教学模式,注重学段与性别特点实施差异化设计,推动学生体质健康干预朝着系统化、科学化的方向发展。
