Studying the implementation of mechanical vibration in sportsmentraining
Abstract
The vibration is the periodic or oscillatory motion of a body or particles of an environment, executed around a position of equilibrium. The vibration of the whole human body (WBV - Whole Body Vibration) represents the exposure of the whole body ensemble to vibrations, the opposite of local vibrations where an isolated muscle or muscle group is stimulated by using a vibrating device. There are numerous specialized studies supporting the utility of mechanical vibration during training and recovery of athletes. Since the mid 90's, mechanical vibrations were used more and more frequently in sports training. In this study we wanted to highlight the impact of general mechanical vibrations-WBV generated by a vibrating bed, on the sportsmen prior to conventional training. In this study, four players, members of the Oradea University FC football team, who participated in official games and competitions, were evaluated. The stance of the subjects who took part in the study was sitting on the vibrating bed with upper limbs on the thighs, inferior members extended and support at spine level in a fixed support. In order to assess the athletes part of the study, we took into account base values, prior to study initiation date and the final values, after 8 weeks of applying the mechanical vibrations, of the following objective parameters: standing long jump; standing high jump; thigh circumference. The benefit of mechanical vibrationsin athlete training is an area that still requires more specialized research to highlight as accurately as possible the manner in which they can be used to improve the athletic performance. The results of this study confirm that under the influence of mechanical vibrations more muscle fibers, motor unitsare activated, respectively, as compared to simple muscle contractions.
