Background : The purpose of this study was investigated for the effect of el ectrical stimulation and progressive resistance exercise(PRE) on the muscula r strength of lower extremity.
Methods : This study was performed on normal 17 males and 22 females su bjects. They were divided into 3 groups(13 subjects per 1 group) using ran dom sampling and executed progressive resistance exercise, russian current stimulation, respectively. In order to compare the difference of muscular str ength, the subjects were measured for muscular strength before and after ap plying progressive resistance exercise, russian current stimulation. Muscular strength was examined using the WEMG-8.
Results : The results of this study were as follows. After the intervention, P rogressive resistance exercise according to the experiment period significan-tly increased muscular strength in three groups(p<.05). After the intervention, Russian current stimulation according to the experi ment period significantly increased muscular strength in three groups(p<.05). Rather than applying each progressive resistance exercise and russian curr ent stimulation, It is to use both methods of two, there were many improve ments to increase muscle strength. After the intervention, phasic muscle was significantly increased than tonic muscle. Change of the maximum value of EMG on body mass index and gender ac cording to the experiment period was no difference(p>.05).
Conclusion : Increase of the muscular strength of lower extremity was mor e effective than it applies respectively that do together progressive resistanc e exercise and russian current stimulation in normal adult.
