Youth long distance runners and their injuries have been understudied, particularly when compared to the amount of existing and ongoing research regarding adult runners. Physical burnout and overuse injuries can have a lasting effect, contributing to medical costs and preventing young athletes from remaining physically active. The findings of this investigation will have applications across youth development and activity, and will lead to a richer understanding of the biomechanics of long distance runners between genders and across maturational levels. The proposed research will capitalize on Drs. John Cronin and Jon Oliver?s study of youth and adolescent athletes at the Sports Performance Research Institute of the Auckland University of Technology, and will generate a more holistic picture of the interaction between biomechanics, neuromechanics, and fatigue in growing athletes.This study aims to analyze changes due to fatigue in the biomechanics and neuromuscular control of male and female long distance runners of varying maturational status. This research will result in a profile of how muscle activity, leg stiffness, and stride length change with fatigue, as these can all be predictors of injury. To achieve this goal, kinetic and kinematic data will be collected during a training run on a treadmill. Leg stiffness and muscle activity will be compared before and after runs using EMG and force measurements. Potential uses of this research include a biomechanical risk prediction model to provide guidelines for safe volume and frequency of running by pubertal stage. The methods employed can also be extended to protect young athletes in other sports where overuse injuries are common, such as baseball. This NSF EAPSI award is funded in collaboration with the Royal Society of New Zealand.

青少年长跑运动员及其受伤情况尚未得到充分研究，特别是与现有和正在进行的有关成年跑步者的研究数量相比。身体倦怠和过度使用损伤可能会产生持久的影响，导致医疗费用增加，并阻止年轻运动员保持身体活动。这项调查的结果将在青年发展和活动中得到应用，并将导致对不同性别和不同成熟水平的长跑运动员的生物力学有更深入的了解。 这项拟议中的研究将利用约翰·克罗宁博士和乔恩·奥利弗博士？奥克兰科技大学运动成绩研究所的青少年运动员的研究，并将产生一个更全面的图片之间的相互作用的生物力学，神经力学和疲劳在成长中的运动员。这项研究旨在分析变化，由于疲劳的生物力学和神经肌肉控制的男性和女性长跑运动员的不同成熟状态。 这项研究将导致肌肉活动，腿部僵硬和步幅如何随着疲劳而变化，因为这些都可以预测受伤。 为了实现这一目标，动力学和运动学数据将在跑步机上的训练运行期间收集。 腿部僵硬和肌肉活动将在跑步前后使用EMG和力量测量进行比较。 这项研究的潜在用途包括一个生物力学风险预测模型，为青春期阶段的安全跑步量和频率提供指导。 所采用的方法也可以扩展到保护其他运动中的年轻运动员，在这些运动中，过度使用损伤是常见的，例如棒球。 这个NSF EAPSI奖是与新西兰皇家学会合作资助的。
