The Effect of Rhythmic Neural, Musculoskeletal Exercises on Relaxation Deepening (Recorded by SCL " Skin Conduct Level" Signals) in National Judo Athletes

Relaxation is one of the important mental skills in physical education and sports activities. Relationship between relaxation and rhythmic exercises with an emphasis on flexibility-functional mechanisms of nervous system has received attention in recent studies. The aim of the present study was to investigate the effect of rhythmic exercises on deepening the relaxation of national judo athletes. For this purpose، 30 male athletes of judo national team participated in this study and were divided into three groups: one control and two experimental groups. The subjects practiced the training protocol for three months and the data were recorded and then analyzed by SCL (Skin Conduct Level) index. The results revealed no significant difference in relaxation among the groups (α=%5 and P>0. 05). In other words، relaxation exercises had a slight effect on improvement of relaxation skill level; however، rhythmic exercises deepened relaxation to some extent. Results showed that rhythmic movements reduced stress through influencing relaxation deepening and subjects with more relaxation were more successful in their optimal movements.
