The global symmetry index, symmetry index, quality index and kinematics of the gait cycle with the synchronized contribution of the latest generation magneticinertial and electromyographic technology. Practical surveys and planning hypotheses for the revision of gesture.

The walk is certainly the cornerstone of human mobility. The literature has focused on the qualitative and quantitative analysis of walking and how certain parameters can change after an aerobic fatigue test. Our research proposal is based, in an innovative way in literature, on the analysis of specific parameters of the gait cycle, considered highly significant, such as the global symmetry index, the symmetry index, the quality index of the gait cycle, pelvic kinematics and muscle activation and the differences in these parameters before and after an aerobic fatigue test (resistance of the gesture over time). A total of 27 male athletes, aged (9-11) participated to the study, in which state-of-the-art equipment was used in the field of movement sciences that includes a device that integrates triaxial inertial sensors and a set of synchronized wireless probes, part of fourth generation instruments, still the most advanced on the market, for wireless surface electromyographic analysis. Thanks to these devices it was possible to carry out an evaluation of the subjects directly, with the live acquisition of data during the entire execution of the test protocol, allowing to evaluate the aforementioned parameters, which are considered strategic in pre-adolescent age, both for a more accurate basic construction of the element sure to offer a better planning of work sessions or training sessions at the time and in the future, also in consideration of periods immediately following high workloads, where fatigue affects the precision of gestures in the young athlete with various consequences, including significant ones, which is not always taken into consideration.
