Warm up can be used for work on footwork combined with some additional cognitive tasks that are highly valuable for every position in handball (or in any other sport), but especially for goalkeepers: the speed of information processing and speed of reaction.
In this video, goalkeeper is responding with fast leg swings on different cognitive tasks on TestYou brain training system. Randomly, there will be added audio stimuli on which goalkeeper needs to add vestibular stimulation – 180 degrees jump turn. And right during the landing there will be another task: another goalkeeper or a coach will show even or odd number (and each will have different following task). So depending on which number will be shown, active goalkeeper will perform set of save reactions.
Combinations of options of save reactions are endless, as well as the choice of stimuli or additional cognitive load.
With TestYou brain training system, you get to work on a more challenging level of brain performance, because you are not reacting only on a given color of the light, but you have to react on a specific symbol (that can be a number, a letter or a symbol) and also on a specific color. While all along, colors and symbols are mixed up and you really need to be able to engage your brain, ignore irrelevant information, decide fast and react with proper reaction on a given color and symbol.
