Abstract Shock and vibration are present in all areas of our daily lives. It may be
transmitted and generated by machine-tools, turbines, motor, towers, bridges, and
even by the human body. Vibration and shock also may desirable, disturbing and
even destructive. It depends on the place and what type of source of vibration that
occurs. This paper presents a case study of the influences of vibration machine,
used in sport exercises, on the human balance and stability. The equipment used is a
vibration machine Insportline, a force platform Kistler and four subjects (mean age
23 ± 1 years; mean weight 75 ± 3 kg; mean height 1.78 ± 0.4 m). The subjects
were analyzed, on the Kistler platform, in three situations: with eyes open, with eyes
closed, and after 1 min of standing on the vibration machine. The analyses consist of
a 30 s stand still on the force platform in an orthostatic position. The parameter taken
into account is the center of pressure of the foot. The results indicate that there is a
slight influence of the vibrations on the balance and stability of the subjects indicated
by the variation of the center of pressure on a 2D plane.
1 Introduction
Vibration machines are said to help lose weight up to three times more quickly
than a regular fitness trainer. Because they transfer vibrations to muscles, and they
present a true revolution in exercising. Nowadays, these machines can be used at
home. It is said that a vibration machine helps you better exercise your muscles,
improve your agility and flexibility, improve your blood circulation, and stimulate
the cardiovascular system [1].
Several studies are centered on the influence of whole body vibrations on the
human balance, equilibrium, stability, locomotion, and so on. These studies have
shown various results [2–8]. Taking them into account, this study is oriented to
detect some new results.
