[Effect of propriocetiv trainings tools for the muscles in stance stability]

Today in each therapy and training program proprioceptive exercises are integrated. A lot of equipment you can buy. But for an more effective training exercises and equipment should be select more regarding the aim and the problem of the training. In literature is not much written about the specific way proprioction equipment stimulate different muscles. In this study 15 students of sport sciences (25.7 +/- 2.2 years, 8 male, 7 female) were tested for a period of 15 seconds in a single-leg standing position on a small rocker board, a wobble board, a gym mat and the Posturomed(c). The exercise was done just one time on each tool in a random way. The effect of the exercise was measured by EMG on six main stabilising muscles, m. tibialis ant., m. peroneus long., m. gastrocnemius med. And lat., m. semimembranosus and m. vastus med. At the end of the test series MVC of each muscle was tested. For the analysis we regarded the first, middle and last second of the test. Also the maximum peak over 0.5 sec. and the average of the whole test was integrated into the data base. The statistics was done with the Wilcoxen-Test. The experimental standard deviation was defined of 5 %. The highest EMG activity we noticed on the small rocker board. The activity was over the whole test series significant higher in the muscles m. tibialis ant., m. peroneus long. and m. gastrocnemius. The m. semimebranusus shows in all exercises the slightest EMG activity, the m. peroneus long. shows the highest activity. During the test all muscles decrease in EMG activity except m. peroneus long. on the small rocker board and the Posturomed. With these facts of EMG activity during proprioceptive exercises we are able to advice training more specifically: Because of the decreasing activity we advice doing repeated intervals not longer than 15 seconds. In the aim of ankle stabilisation use the small rocker board and the gym mat. For rehabilitation and prevention on the knee use the Posturomed, the mat or even the small rocker board. The advocacies are given looking to the tested rehab tools.
