OptoJump Next - Reaction Test

The distinction is made between simple and complex reactions.
By simple reactions, we mean movements which are characterized by the movement of a very small part of the body. For example, pushing a button with the hand or foot or analogously leaving the OptoJump measurement area.

Complex reactions are movements which involve an important part of the body or the whole body.
This is the case, for example, in 5m sprints, brief start movements from various positions and the brief bursts of movement associated with coordination tasks which must be performed very quickly. Simple reactions are mainly regulated by processes of genetic dominance. Complex reactions are
influenced above all by social factors such as training.

• Acoustic reaction (the stimulus is in the form of a beep or recorded sound)
  • Simple Reaction
    • Lower Limbs
      • I lift my foot
      • I enter/leave the mat with one foot (the other foot acts as an external pivot)
    • Upper Limbs (Optojump placed on a table)
      • I lift my hand
      • I enter/leave with one hand
  • Complex Reaction
    • Lower Limbs
      • Performance of a jump starting from SJ position
      • Performance of a run to a point and back (also more than once, with the aim of touching a cone or performance of another action).
    • Upper limbs
      • My hand leaves as it performs an action (I move an object)
      • I move an object from inside to outside the area.
• Visual Reaction (the visual stimulus is a change in the colour of the PC screen or a changing light on an external signal light).
  • See acoustic reaction for test
• OptoAcoustic Reaction (It is not specified whether the stimulus is to be visual or acoustic. The athlete must react to both stimuli).
  • An interesting variation of complex reaction is when the athlete must not react to one of the two stimuli or react by following pre-set courses or with different actions.
