Auswirkung propriozeptiver Trainingsgeräte auf beteiligte Muskulatur im Einbeinstand

Abstract

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.

Effects of different unstable supports on EMG activity and balance

“…First and quite similarly than CoP, the smaller the board bases, the higher the muscular participation. Such conclusion has previously been obtained [9]. But, as for CoP variability, we are surprised to detect high EMG activity for both TA and SOL muscles in FREEMAN as well as in LATERAL boards.…”

“…Let's remember that this latter exclusively allowed mediolateral displacements while TA and SOL act in anteroposterior direction. Quite similarly, Dohm-Acker et al [9] previously registered the highest EMG activity in TA, PL and gastrocnemius muscles. Also, Braun Ferreira et al [1] found high EMG activity in TA (in association with PL) on trampolines and force platforms.…”

Effects of Increasing Balance Task Difficulty on Postural Sway and Muscle Activity in Healthy Adolescents

“…Further, studies investigated the effects of increasing BTD on neuromuscular activity. Results showed that lower limb muscle activity (Dohm-Acker et al, 2008; Cimadoro et al, 2013) and coactivation (Donath et al, 2016) increased with increasing BTD. In fact, recent studies on the progression of BTD were mainly conducted using various environmental conditions to manipulate posture (e.g., BoS, training device, surface, vision, etc.)…”

Zuverlässigkeitsprüfung eines Messverfahrens zur Charakterisierung des Standverhaltens und Quantifizierung des Balancevermögens auf einer instabilen Plattform (Posturomed)

“…Probanden, die ihre Vorerfahrung "hoch" oder "sehr hoch" einschätzen, weisen ein geringeres Wegsignal auf als Probanden, die ihre Vorerfahrung als "gering" oder "mittel" bezeichnen. Die Verbesserung der Werte auf dem Posturomed nach Trainingsintervention ist bekannt[16,17], sodass die Hypothese des positiven Einflusses bestimmter Sportarten, die Einbeinstand oder gute Gleichgewichtsfähigkeit auf einem Bein fordern, nahe liegt. Dies hat sich auch in den Messwerten bestätigt.…”
