Comparison of electromyographic activity of selected muscles during exercises on rocker board and balance sandals
Abstract
The study investigated, documented, compared and analyzed EMG activity of selected muscles in the course of two kinds of simple exercise with the use of balance aids. The surface EMG method was used in seven healthy probands and electromyographic activities of mm.gluteus maximus et medius, m.erector spinae, mm.vastus medialis et lateralis were compared in basic position, in standing on one leg, hovering or and walking while standing still on the balance sandals as well as on the rocker board in the anterior posterior plane.
Based on the results obtained the authors recommend to use the cylinder segment as well as balance sandals as suitable aid for activation and strengthening m.gluteus medius. In selecting the aid the authors recommend to consider the degree of training or non-training of the individual and select the aid within the framework of progressive training, i.e. to begin with the simple aids and to continue with the more requiring ones.They also warm against new trends, which have not been so far based on quality research.
