Daily Mobility Exercises by Dr. Kelly Starrett Forums General Marc Pro – Anyone know how this works vs. a TENS unit? Re: Marc Pro – Anyone know how this works vs. a TENS unit?


Some additional information from Gary Reinl of Marc Pro:
Since all
muscles contractions essentially “look” the same (the muscle contracts)
… your observation that the contractions produced by a MARC PRO unit
look the same as contractions produced by TENS unit is correct.
In fact, if you have ever been shocked by a faulty electrically wire in
your home … the contraction produced by that encounter would also
“look” the same. That said, the contraction produced
by that faulty wire (or a TENS) would not “feel” the
same. Additionally, if you continued
“shocking” yourself with that faulty wire (or a TENS)
you would eventually fatigue/damage the involved muscle. My point is
this; if you want to fatigue a muscle, MARC PRO is the wrong tool. MARC
PRO will not fatigue your muscle (instead, it will facilitate and
enhance muscle performance and recovery). 

Important additional point, since TENS is
not designed (or cleared by the FDA) to facilitate and enhance
muscle performance and recovery and MARC PRO is, it is unfair to compare
results between the two devices (TENS is a pain management
device not a muscle performance/recovery device).
