Giovanni,
Have you read this recent study? It was in this month’s JSC.
Restoring Muscle Work Capacity With Electrical Stimulation
http://www.ncbi.nlm.nih.gov/pubmed/22549086
It says that endurance athletes were able to improve their work capacity in their calf muscles with EMS more than the athletes that didn’t use EMS. The protocols were a bit broad, saying that it used mild impulse frequency of 20hz to 120hz, 2sec ON/2secOFF, 20-25 mA intensity for 10 minute duration, 4 hours after the training session. It states that recovery would be less effective if it were performed any less than 4hrs after the training session because the recovery metabolic changes take place 2-4 hours after loading.
Let me know what you think. Do you agree with the protocols used in the study?
