Objective: To compare the effect of two methods of electrostimulation on the following variables: strength and anthropometry. Method: An experimental, randomized, and simple blind investigation was performed. Eighteen subjects were evaluated distributed into a Modified TENS Current Group (CTM: n = 6), Russian Current Group (CR: n = 6), and a Control Group (TC: n = 6, submitted to traditional TENS current, considered as placebo in this research). Results: After 8 weeks, only CTM obtained an increase in maximal strength (p < 0.035), and a reduction in the subcutaneous fat thickness of the right thigh (p < 0.03). Conclusions: A Modified TENS Current is effective for muscular training.
