(2022). Championship interseason period did not reduce knee peak moment: A 10-years retrospective study of 467 elite soccer players. Biomedical Human Kinetics, 14(1), 2022. 204-210. https://doi.org/10.2478/bhk-2022-00252080-2234http://hdl.handle.net/10400.26/59509Study 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.engIsokineticStrengthTrainingPerformanceSportcontribution to journal10.2478/bhk-2022-0025
