FITNESS & WELLNESS
The training with Physioplate permits to achieve and maintain a great physical shape and to feel a sense of wellbeing, thanks to the combined effects of vibrations:
- Secretion of natural anabolic hormone (testosterone and GH)
- Increase in force and muscular power
- Strengthening of bone and articular structures.
FLEXIBILITY AND ARTICULAR MOBILITY
Vibrations work on tendons, capsules and connective tissues and prompt the elimination of viscosity and adherences, thus favoring tissue movement and increasing articular amplitude.
The stimulation of Golgi tendon receptors inhibits the contraction of antagonist muscles, thus decontracting them and favoring a greater stretching capacity.
HEART AND BLOOD CIRCULATION
Physioplate, with a few minutes of daily stimulation, increases peripheral circulation from 100 to 150%, favors blood oxygenation, venous return and lymphatic drainage with beneficial effects for people who suffer from bad circulation.
SPORT & TRAINING
SPORT AND HORMONE SECRETION
The correlation between the specificity of the sport practiced and the hormonal profile of the athlete is well known: indeed exercise can induce a significant hormonal response, not only in terms of acute adaptation to the exercise itself, but also as long-term response to the exercise itself (Inoue and coll., 1994; Viru, 1994; Kraemer and coll., 1996). The vibration training, too, produces adaptive hormonal response with an increasing in TESTOSTERONE (C) and SOMATOTROPE HORMONE (GH) concentration together with a decrease in the concentration of CORTISOLE (C) (Bosco and coll., 2000). The VT, if adequately repeated, can induce long-term hormonal adaptations that imply another long-term adaptation of neuromuscular functions (Bosco and coll., 2000).
A Physioplate training with sinusoidal vibrations at 26/28 Hz of frequency causes a very important increase in mechanical power. Runge and coll. (2000) report an increase by 18% in lower limb power in an elderly population undergoing vibration training with the following procedure: 3 sessions per week, 3 repetitions each one lasting 2 minutes at a frequency of 27 Hz, for a total duration of 12 weeks.
After a vibration training of 12 weeks, Decluse and his collaborators (2003) have recorded a significant increasing in isometric and dynamic force of lower limbs corresponding to 16.6 and 9.0%, respectively. These results show that the vibration training brings about a correlated adaptation and a neural strengthening, similar to those induced by the traditional training of force and power.
RECRUITMENT MODE AND PROPRIOCEPTION
During the training with vibrations, the interneurons placed in the spinal cord receive input both by the afferent and descending fibers, influencing motoneurons activities. The interaction of these different inputs determines how motor units are recruited during movement. The increase in force in the first phases of training is triggered by an optimization of this mechanism of proprioceptive feedback (Gandevia, 2001).
The vibration training can improve the explosive force capacity thanks to a high synchronization of the motor units involved in the movement, to an improvement in the coordination of synergic muscles and to an increase in the inhibition of the antagonist muscles (Bosco and coll., 2000). Importantly, the vibration training can induce positive and long-term neuromuscular adaptations.
STIMULATING FAST FIBRES (FT)
During vibrant training, the body undergoes huge acceleration stress: for example, at a frequency of 30 Hz and an oscillation amplitude of 5 mm, the body is subject to an acceleration 18 times higher than the acceleration of gravity (Rittweger and coll., 2001). On the other hand, during a classic plyometric exercise (jump with a previous downward fall), the acceleration developed is only equal to 5 G. Undergoing such strong acceleration is a very important factor to increase power.
COMPARISON OF VIBRATION TRAINING WITH OTHER TYPES OF TRAINING
Vibration training in sport is very effective: 10 minutes of vibration training with an acceleration of 17 G correspond to the same acceleration load obtained with 40 sessions of 200 drop jumps falling from an height of 100 cm (Bosco and coll., 2000).
LIPOLYSIS & CELLULITE
Vibration platform training brings about an increase in calorie consumption, due to the muscle work on the platform, and an increase in basal metabolism, which is the calorie requirement in rest condition. The organism, thanks to the greater secretion of GH hormone, consumes fats to respond to the higher energy consumption, thus causing an important slimming effect.
The massaging effect and the increase in blood circulation help fight cellulite.
MASSAGE AND RELAXATION
Stimulation with vibrations produces an effect comparable to a deep and relaxing massage, thanks to the following combined actions:
- Vibrations move the tissues, thus eliminating adherences and making them softer
- The stimulation of receptors decreases muscular tone and eliminates contractures
- The increase in blood circulation and the drainage of interstitial fluids favor recovery.
ARTHROSIS & HEARTH
The arthrosis is a degenerative alteration of the articular cartilages that involves 80% of the elderly. This progressive disease, which often leads to disability, changes the characteristics of the cartilage tissue that can no longer absorb mechanical stress and protect articulations. The stimulation with the vibrations of Physioplate permits to stop the degenerative process and to improve articular functionality thanks to the secretion of synovial fluid that lubricates and imbibes cartilages and reduces pain.
The therapy with vibrations brings about a reduction in blood viscosity and an increase in the average speed of circulatory flow (Kerschan and coll., 2001). The peripheral circulation can considerably increase up to 150%, with beneficial effects on metabolism and on oxygen contribution of to the tissues. On the other hand, the circulatory bed favors the decrease in PA.
The vibration training is therefore particularly useful for people who suffer from circulatory disorders such as arteriosclerosis or insufficient lymphatic drainage.
Veins of lower limbs have special valves that let blood flow only upwards, making the blood return towards the heart easier. These valves can become inadequate in obese or sedentary people, so that the venous blood, poor of oxygen, becomes stagnant in legs, thus exercising greater pressure on the venous wall, which causes varices.
The stimulation with Physioplate by the activation of a rapid succession of eccentric and concentric muscle contractions reinforces the natural muscle pump that favors the circulation and lightens the work of valves and venous walls.
Osteoporosis has become a real socio-economical problem affecting all elderly population.
Osteoporosis is a complex-etiology metabolic disease of bone tissue, characterized by a localized or generalized reduction in bone tissue.
The bone matrix, consequent to an unbalance between speed of synthesis and speed of degradation remains mineralized but quantitatively reduced.
A radiological exam would highlight bone rarefaction, thinning and reduction of trabecules and an increase in marrow spaces.
Osteoporosis affects one woman out of four, and one man out of eight. There is a senile and postmenopausal form, and a secondary form associated with prolonged immobilization and endocrine disorders.
In women in particular, the deficit of estrogens during menopause causes bone mass loss.
The application of the vibration therapy, which is perfectly in line with the characteristics of the elderly population as regards intensity and duration, is a widespread therapeutical means in geriatric medicine to stimulate bone metabolism, even in the presence of an osteoporotic degeneration (Petrofski and Phillips, 1984; Flieger and coll., 1997; Rittwerger and coll., 2000).
STATIC AND DYNAMIC BALANCE AND MUSCULAR FORCE
The locomotor apparatus functionality in geriatric age is given by the muscular functionality of lower limbs, the muscular-articular mobility, the biomechanics of gait and the static and dynamic balance (Guralnick and coll., 1995). Some researchers suggest that the crucial factor to pre-empt falls during deambulation is muscular power. The ability of the lower limb muscles to produce power can be considered as the most important factor to pre-empt falls of the elderly (90% of hip fractures is caused by falls). Indeed, the vibration training is to be considered as an active exercise.
THERAPY AGAINST MUSCULAR HYPOTOPHY
The vibrant training activates muscles through a rapid succession of brief and intense eccentric and concentric contractions (Rittweger and coll., 2001). In addition, in the light of the active involvement of the muscles undergoing that stimulus, the vibration training requires an energy cost that can be quantified precisely. For instance, a vibration training based on a frequency of 26 Hz and with 6 mm of oscillatory amplitude requires an energy amount comparable to a moderated walk (this energy cost can be augmented by increasing frequency and amplitude of vibrations).
MOTOR COORDINATION AND EQUILIBRIUM
The incidence of hip fractures due to falls reaches dramatic figures, close to 90%, in the elderly population, and this without considering the so-called "osteoporotic" hip fractures.
The vibration platform stimulates the structures of the central and peripheral nervous system controlling movement, with extraordinary results on proprioceptive control, on motor coordination and on equilibrium.
For this reason, PhysioPlate is fundamental in post-surgical rehabilitation, in proprioceptive recovery, and to treat patients affected by neuromotor disorders.
NERVOUS SYSTEM AND NEUROTRANSMITTERS
As explained above, the force increase after a vibratory stimulation at first is imputable to an optimization of the mechanisms of neural adaptation (Gandevia, 2001). These adaptations translate into the ability of the subject to have a greater and more effective movement control.
These mechanisms have been used to treat with vibrations hemiplegic patients, patients affected by the Parkinson's disease and in the proprioceptive re-education.
The secretion of neurotransmitters (dopamine and serotonin) taking place during the vibration therapy is also very important.
