To examine a school-based high-intensity neuromuscular training (NMT) program in reducing sport injury risk and improving fitness in youth.
Students (ages 11-15) (n = 725) in physical education (PE) classes were randomized by school to intervention or control groups.
A 12-week high-intensity NMT program (including aerobic, strength, balance, and agility components) was designed to reduce sport injury risk and improve measures of fitness. The control program was a standard of practice warm-up (including running and stretching).
A Poisson regression model using an intent-to-treat analysis demonstrated a reduced risk of sport injury: incidence rate ratio (IRR)all injury = 0.30 (95% CI, 0.19-0.49), IRRlower extremity injury = 0.31 (95% CI, 0.19-0.51), IRRankle sprain injury = 0.27 (95% CI, 0.15-0.50), and IRRknee sprain injury = 0.36 (95% CI, 0.13-0.98). A change in waist circumference: -0.99 centimeters (95% CI, -1.84 to -0.14) and an increase in indirect measures of aerobic fitness: 1.28 mL·kg·min (95% CI, 0.66-1.90) in the intervention school compared with the control school also occurred.
A NMT program in junior high school PE class was efficacious in reducing sport-related injury and improving measures of adiposity and fitness in the intervention group.
研究一项基于学校的高强度神经肌肉训练（NMT）计划在降低青少年运动损伤风险和提高身体素质方面的效果。
体育课上的学生（11 - 15岁）（n = 725）按学校随机分为干预组和对照组。
设计了一项为期12周的高强度NMT计划（包括有氧运动、力量、平衡和敏捷性训练），以降低运动损伤风险并改善身体素质指标。对照计划为标准的热身练习（包括跑步和拉伸）。
采用意向性分析的泊松回归模型显示运动损伤风险降低：所有损伤的发病率比（IRR）= 0.30（95%可信区间，0.19 - 0.49），下肢损伤的IRR = 0.31（95%可信区间，0.19 - 0.51），踝关节扭伤损伤的IRR = 0.27（95%可信区间，0.15 - 0.50），膝关节扭伤损伤的IRR = 0.36（95%可信区间，0.13 - 0.98）。与对照学校相比，干预学校的腰围变化为 -0.99厘米（95%可信区间，-1.84至 -0.14），有氧适能间接指标增加1.28 mL·kg·min（95%可信区间，0.66 - 1.90）。
初中体育课中的NMT计划在降低干预组与运动相关的损伤以及改善肥胖和身体素质指标方面是有效的。
