• Static endurance: the average increase is 30.3% at an average stimulation frequency of 75 +/- 44 Hz. (1, 2, 3)
  • Dynamic endurance: the average increase is 41% at an average stimulation frequency of 76 Hz +/- 10 Hz (2, 4, 5, 7).
  • Long-term stimulation with low frequency stimulation of skeletal muscle in experiments on animals (rabbits) resulted in the development of mainly slow twitch muscle fibres with a high proportion of mitochondria (6).
