RESUMO
Vibration biomechanical stimulation as the physiological basis of vibration physical exercises (whole body vibration) causes reflecting muscle contractions like tonic vibration reflex. This type of intervention leads to high intensive stimulation of proprioceptors as called muscle spindles which result in alteration in parameters of activity and developments of human physiological functions. This type of training has broad positive influence on organism. Acceleration physical exercises improve muscle performance, flexibility, nervous function, significantly increase bone mineral density, physiological secretion of anabolic hormones, growth and anti-aging factors; normalize/decrease cortisol as anti-stress effect and are beneficial for balance and mobility as well. It is showed acceleration training caused by vibration stimulus is beneficial for people suffering from osteoporosis and obesity, for rehabilitation of nervous and motor function in patients with Parkinson's disease, multiple sclerosis and stroke.

The role of neuronal structures in the rostral parts of the ventral surface of the medulla oblongata of the rat in regulating the central inspiratory activity of the respiratory center was analyzed. It is suggested that neuronal structures of the subretrofascial area, located close to the ventral surface of the medulla oblongata have direct associations with the mechanisms generating and regulating the respiratory rhythm. These have excitatory effects on neurons of the respiratory center which generate inspiratory activity.

The role of neuronal structures of the rostral ventromedullary area in regulation of central inspiratory activity, was studied. The data obtained suggests that the structures of subretrofacial area are important for the respiratory rhythm generation due to regulation of excitability of the inspiratory neurons.
