Aim
You practise stopping a step you have already begun. You need the same ability when an obstacle appears unexpectedly while walking. The technical term is a go/no-go task.
Equipment in the practice
- Four reaction lights, set to two colours in the app
- The share of no-go signals can be set there
- A chair with a backrest
Equipment at home
- Two green and two red sheets of paper or adhesive dots
- A second person with a stack of red and green cards
- A chair with a backrest or a clear wall
Setting up
- Place four targets in a half circle in front of you, two green and two red.
- The distance is again about one stride.
- The second person stands where you can see them without turning your head.
- The chair is within reach of one hand.
How to do it
- Stand in the middle, feet hip width apart.
- The second person holds up a card.
- On green, step onto a green target.
- On red, stay where you are and shift your weight back onto both feet.
- Return to the middle after every step.
- Twenty signals make one round. Do three rounds with one minute of rest.
Three levels
Level 1: holding rarely
One in five signals is red. The second person raises the card slowly. You have two seconds. One hand rests on the backrest.
Level 2: holding more often
One in four signals is red. The card appears without warning. The time window is one second. Your hand is free.
Level 3: reversing the rule
After ten signals the second person calls "switch". From then on red counts and green means stay. The switch comes at a different point in every round.
If you practise on your own
Shuffle a stack of fifteen green and five red cards and place it face down beside you. Turn a card over and act on the rule. Because you turn the card yourself there is no time pressure. You still practise the stopping.
Safety
- Stopping shifts your weight backwards. Make sure there is one metre of clear space behind you.
- Start with one hand on the backrest until ten stop signals go safely.
- If you wobble repeatedly when stopping, go back one level.
Duration and dosage
Six to eight minutes. Two to three times a week. This exercise tires your attention faster than the others. Put it at the start of the session.
