Abstract：
Background: Physical literacy and injury prevention strategies use similar movement-related constructs and can be connected to develop comprehensive interventions. We aimed to test the feasibility and effects of a neuromuscular warm-up based on physical literacy and injury prevention strategies for 8-12-year-old children. Methods: We conducted a cluster non-randomized controlled trial. We defined a priori feasibility criteria and studied the effects of the intervention on physical literacy constructs, movement competence, and neuromuscular performance. We used generalized linear mixed models controlling for covariates and clustering with a significance level of 0.001. Results: We recruited 18 groups (n = 363) and randomly allocated nine to intervention (n = 179; female = 63.7%, age = 9.8 ± 1 years) and nine to control (n = 184, female = 53.3%, age = 9.9 ± 0.9 years). We met four of seven feasibility criteria (i.e. recruitment, adherence, enjoyment, perceived exertion). The three feasibility criteria that were not met (i.e. compliance, fidelity, follow-up) were slightly below the predefined threshold (90%). Model-adjusted mean differences for physical literacy constructs, movement competence, vertical jump height, horizontal jump distance, 20-m sprint time, and dynamic balance favored the intervention (p < .001). Conclusion: The feasibility evidence indicates that the intervention should be slightly modified before implementing it in a larger study. The observed mean differences are promising and can be used in planning future interventions.
摘要：
背景：身体素养和伤害预防策略使用类似的运动相关结构，可以联系起来制定综合干预措施。我们旨在测试基于8-12岁儿童的身体素养和伤害预防策略的神经肌肉热身的可行性和效果。方法：我们进行了整群非随机对照试验。我们定义了先验可行性标准，并研究了干预措施对身体素养结构的影响，运动能力，和神经肌肉表现。我们使用广义线性混合模型控制协变量和聚类，显著性水平为0.001。结果：我们招募了18组（n=363），随机分配了9组进行干预（n=179；女性=63.7％，年龄=9.8±1岁）和9岁（n=184，女性=53.3%，年龄=9.9±0.9岁)。我们符合七个可行性标准中的四个(即招聘，坚持,享受,感知到的努力)。未达到的三个可行性标准(即合规性、保真度，随访)略低于预定阈值(90%)。身体素养结构的模型调整平均差异，运动能力，垂直跳跃高度,水平跳跃距离,20米冲刺时间，动态平衡有利于干预(p<.001)。结论：可行性证据表明，在更大的研究中实施干预措施之前，应稍加修改。观察到的平均差异很有希望，可用于规划未来的干预措施。
