The subjects in the static stretching group performed stretching exercises for the ankle evertor and dorsiflexor muscles 5 days a week for 6 wks. Peroneal and tibialis anterior muscle reaction characteristics were evaluated at the beginning (2 times for acute effect) and end of this period. Electromyographic activity parameters of the muscles were measured using an ankle inversion tilting platform that simulated a sudden ankle inversion. The following were the four different ankle inversion conditions: (a) ankle-neutral, 15-degree inversion; (b) ankle-neutral, 30-degree inversion; (c) ankle-20-degree plantarflexion, 15-degree inversion; and (d) ankle-20-degree plantarflexion, 30-degree inversion.Results: Either in terms of acute or chronic effects, no significant differences were found after static stretching exercises for peroneal and tibialis anterior muscle reaction time, reaction duration, and muscle activity evaluated in four positions on the ankle inversion simulation platform (P > 0.05).Conclusions: In light of these results, it is possible to state that the short duration of static stretching exercises can still be applied before sports activities.eninfo:eu-repo/semantics/closedAccessChronic ankle instabilityRisk-factorsInjury riskInversionPerformanceFlexibilityExerciseLatencyReflexElectromyographyStatic stretchingAnkle sprainElectromyographyMuscle latencyScience & technologyLife sciences & biomedicineSport sciencesRehabilitationArticle00045599010001313614698210.1097/PHM.0000000000001036
