Abstract

Abstract Study aim: To compare knee moment profiles of professional soccer players from different playing positions before and after an interseason period. Material and methods: Retrospective study of 467 healthy, professional elite Brazilian soccer players before and after an official championship interseason period during 10-years. Main outcome measures were isokinetic peak moment from knee extensors and flexors from concentric and eccentric contractions. A Two-way ANOVA analysis was used to compare each playing position before and after interseason period. Results: It was found no statistical difference in Ext.CPT (from p = 0.11 to p = 0.97), Ext.EPT (from p = 0.07 to p = 0.85), Flx. CPT (from p = 0.14 to p = 0.90) or Flx.EPT (from p = 0.10 to p = 0.91) between End-Season and Pre-Season evaluations for all playing positions (from Goalkeepers, Defenders, Backsiders, Midfielders and Forwards). Conclusions: Isokinetic peak moment did not have significant differences after an interseason period of 4 to 6 weeks, allowing trainers and coaches to focus their pre-season period on other performance concerns than strengthening.

冠军赛间歇期没有减少膝盖峰值时刻:一项对467名精英足球运动员的10年回顾性研究

摘要:研究目的:比较不同位置职业足球运动员在赛季前和赛季后的膝关节弯矩特征。材料与方法:回顾性研究了467名健康的巴西职业精英足球运动员在10年的官方锦标赛季间期前后的情况。主要的结局指标是由同心圆和偏心收缩引起的膝关节伸肌和屈肌的等速峰值力矩。采用双因素方差分析比较每个球员在赛季间期前后的位置。结果:Ext.CPT(从p = 0.11到p = 0.97)、Ext.EPT(从p = 0.07到p = 0.85)、Flx(从p = 0.07到p = 0.85)两组间差异无统计学意义。CPT(从p = 0.14到p = 0.90)或Flx。所有上场位置(门将、后卫、后腰、中场和前锋)的赛季末和赛季前评估的EPT(从p = 0.10到p = 0.91)。结论:在4 - 6周的季间期后，等速峰值力矩没有显著差异，这使得训练师和教练可以将他们的季前训练集中在其他性能问题上，而不是加强训练。
