Abstract

Objectives: To investigate the relationship between core stability and neuromuscular performance (i.e., sprint velocity and change-of-direction speed) among adolescent male football players.

Methods: In this cross-sectional study, sixteen high-level male football players were divided into higher and lower core stability groups based on their performance in a partial range single-leg deadlift (SLD) test, assessed using a smartphone application (OCTOcore© app). Neuromuscular performance was assessed with a 30-m maximal sprint test (with 5-m split intervals) and a V-cut test, and these outcomes were correlated with SLD test results.

Results: Statistically significant differences were observed between higher and lower core performance groups in the SLD test (p = 0.001) and between SLD non-dominant and 30-m maximal sprint test (p = 0.001-0.005), while no differences were founded between SLD performance and V-cut test (p>0.05). A large correlation was found between non-dominant SLD and 10-m sprint performance (r = 0.765, p = 0.001), while moderate correlations were observed for the 15-, 20-, 25-, and 30-m sprints (r = 0.508-0.562, p = 0.023-0.044). No significant correlations between SLD performance and the V-cut test (p>0.05).

Conclusion: Core stability appears to be positively associated with sprint performance (0-30 m) but not with change-of-direction speed, suggesting that it plays a greater role in linear acceleration than in multidirectional tasks.

智能手机评估的单腿硬举稳定性与青少年足球运动员的冲刺速度有关：一项横断面研究。

目的：探讨青少年男子足球运动员核心稳定性与神经肌肉运动表现（即冲刺速度和方向变化速度）的关系。方法：在这项横断研究中，16名高水平男子足球运动员根据他们在部分范围单腿硬举（SLD）测试中的表现分为高核稳定性组和低核稳定性组，使用智能手机应用程序（OCTOcore©app）进行评估。神经肌肉性能通过30米最大冲刺测试（5米分裂间隔）和V-cut测试进行评估，这些结果与SLD测试结果相关。结果：SLD测试中高、低核心性能组之间差异有统计学意义（p = 0.001）， SLD非优势组与30米最大冲刺组之间差异有统计学意义（p = 0.001 ~ 0.005），而SLD测试与V-cut测试之间差异无统计学意义（p < 0.05）。非优势SLD与10米短跑成绩之间存在显著相关（r = 0.765, p = 0.001），而15米、20米、25米和30米短跑成绩之间存在中度相关（r = 0.508-0.562, p = 0.023-0.044）。SLD表现与V-cut检验无显著相关（p < 0.05）。结论：核心稳定性与短跑成绩（0-30米）呈正相关，而与换向速度无关，这表明核心稳定性在直线加速任务中的作用大于在多向任务中的作用。

期刊介绍： The Journal of Musculoskeletal and Neuronal Interactions (JMNI) is an academic journal dealing with the pathophysiology and treatment of musculoskeletal disorders. It is published quarterly (months of issue March, June, September, December). Its purpose is to publish original, peer-reviewed papers of research and clinical experience in all areas of the musculoskeletal system and its interactions with the nervous system, especially metabolic bone diseases, with particular emphasis on osteoporosis. Additionally, JMNI publishes the Abstracts from the biannual meetings of the International Society of Musculoskeletal and Neuronal Interactions, and hosts Abstracts of other meetings on topics related to the aims and scope of JMNI.
