THE MADE IN JAPAN "ELESAS" IS A PORTABLE MICROCURRENT THERAPY UNIT TO RELIEVE PAIN & RELEASE MUSCLE TENSION.

When the skeletal muscle continues to contract, its tension gradually decreases; this phenomenon is called “muscle fatigue”. The causes of muscle fatigue are roughly divided into two: accumulation of metabolic by-products and damage to organelles of muscle cells (muscle damage). Recovery of muscle fatigue takes a long time if muscle damage occurs. (Allen et al., 2005). Among athletes who are required to exert especially large power, like hammer throw and weight lifting etc., repeats heavy training. Because ECC (eccentric contraction) is involved in various physical activities, it is thought that many of the causes of long-term muscle fatigue that occur in these athletes are due to muscle damage. In order to improve training efficiency, it is necessary to take measures: such as reducing muscle fatigue from muscle damage or promoting recovery from fatigue.

(1) Eccentric contraction

The rats were divided into E (eccentric) group with ECC load (n = 20) and Sed (sedentary) group without load (n = 10), and E group was loaded with ECC according to the method of Kanzaki et al. (2010).

(2) Microcurrent treatment

(After dividing into group E and group Sed) Group E was again divided into ET (eccentric + treatment) group (n = 10) with treatment by ElesAs and the not treated EN (eccentric + non-treatment) group (n = 10). The ET and Sed group were treated 20min./day for 4 days to the same left leg and by the same protocol (0.3 Hz, 25 μA, mode 1.).
