For the acceleration as well as the deceleration all h/p/cosmos running machines have 7 intensity levels. The individual selectable acceleration and deceleration parameters of speed include intensities from extremely slow to extremely fast. Top speed can be reached in anything from 3 to 131 seconds.

h/p/cosmos intensities for acceleration and deceleration

Slow acceleration (level 1 or 2) is for rehabilitation and for
   fitness for beginners

Medium acceleration (level 3 or 4) is for well trained subjects
   for speeding up or slowing down pretty fast

High acceleration (level 5 to 7) is only for top athletes for sprint
   training and other competitive sports applications

Therefore the high accelerations are only accessible via
   special release in the optional functions, protected by access
   key

The acceleration levels are accessible via pressing the
   "speed-keys" + and minus several times and then holding the
    key

The acceleration levels are programmable for every single
   program step of the individual profile and tests

The acceleration levels are accessible via interface and
   optional PC software h/p/cosmos para control and
   h/p/cosmos para graphics
