Abstract

research shows that during multi-directional sprints, athletes must maintain a certain degree of stability and balance during the transition from a dynamic state, to a momentarily static state to change direction, before returning to another dynamic, acceleration. An optimal dynamic balance would help to maintain a stable centre of gravity, allowing better optimization of the action times in the technical execution of the performed gesture. The role of body imbalances and their effect on the performance of linear and multi-directional acceleration will require further significant studies, especially related to the muscular and articular biomechanics of the gestures, to better clarify the personalization of performance in the different executive speeds, to establish the different commitment on the osteo-muscular system. The main aim of this study arises from the idea that a symmetrization of the sides of the body, will certainly benefit the dynamics in question. The aim is to identify the elements of symmetry of the human body and how it can be performative, in a general sense, thanks to the use of inertial sensors (IMU), which allow to obtain extremely high precision data on which to calibrate the training and performance work parameters. Data collection was performed using latest generation IMU sensors worn by the subjects using special undershirts. The research protocol was carried out on 104 young football players (average age 11.7). Two tests were performed, the first was carried out during the summer preparation (preseason, T1), the second was at the end of the football season (postseason, T2). The parameters under attention were: Training load, AVG Strength and Lateral Imbalance. The results of the comparison of the two tests were: for Training Load, 74 players (71.16%) showed a decrease and 28 an increase (26.92%) and 2 a zero variation (1.92%); for Average strength, 52 players (50%) had a decrease and 49 an increase (47.12%) and 3 a zero change (2.88%) and for Imbalance, 46 players (44.23%) showed a decrease and 58 an increase (55.77%).These three parameters, are respectively expression of force, force distribution and dynamic body imbalance provide data on the real abilities useful for optimal performance in changes of direction for each of the items investigated and therefore, they give the possibility to create more specifically adequate training programs.
