| Abstract |
The purpose of this study was to investigate and verify effects of 12 week neuromuscular training on vestibulo-ocular reflex and vestibulo-spinal reflex in free style ski players. Subjects of this study were 14 Korean male and woman free style ski players. Amongst the subjects, national-class players were assigned randomly as an experimental group (n=7) and the rest players as a control group (n=7). During the experimental period two groups had a same physical training which included weight training, interval training, circuit training etc. Experimental group performed neuromuscular training(2 hour a day, 3 time for 12 week) which is inclusive of BOSU, wobble board, trampoline, exercise ball and plyometric training as an addition to physical training. This study also conducted chair rotation test and dynamic posturography test targeting both groups between pre and post-test. Results of this study are as follows. First, As a result of chair rotation test, a significant difference (p<.05) was found between groups and interaction in gain at 0.4Hz, and time and interaction in gain at 1.6Hz. There is no significant in phase. In symmetry, significant difference was found between groups in 1.6Hzs. In both clockwise and anticlockwise rotations, no significant difference was found between groups. Second, following results were obtained through analyzing of vestibulao-spinal reflex. As a result of dynamic posturography test, no significant difference in condition 2, 3, 5, 6, but there is difference in condition 1 at time and condition 4 at groups. In conclusion, 12 week neuromuscular training is considered a useful training method for enhancing free style ski players dynamic balance. |
