Performance determination of combatants' Speed-power abilities by technical means

The article presents a retrospective analysis of using various technical devices to assess the strength and speed of taekwondo fighters' strikes performance during training sessions and competitive activity. At present time in taekwondo different variants for studying speed-power characteristics of combatants are practiced by means of various types of sensors fixed on the athlete' body or on a training mannequin. The accumulated experimental experience of using technical means to determine the speed-power indicators demonstrated by taekwondo athletes when performing various technical actions allows us establish the expediency of using accelerometers located on the athlete's body or at a target within the training process. The paper presents materials showing that it is better to assess the accuracy and speed-power characteristics of an impact using devices developed on the basis of an accelerometer. The arguments are given in favor of the fact that kick power assessment using pressure sensors is less effective in relation to devices with strain-gauge indicators and accelerometers.
