  Abstract:  VIEW PDF: VISUAL CONTROL OF POSTURAL BALANCE OF FIELD TENNIS PLAYERS

Background. Cognitive control processes include a broad class of mental operations including goal or context representation and maintenance, and strategic processes such as attention allocation and stimulus-response mapping. Cognitive control is associated with a wide range of processes and is not restricted to a particular cognitive domain. Aims. The aims for this research are the following: 1. The determination of area and length for the trajectory of the weight center’s projection using AMTI Netforce platform, 2. Identifying the influence of the visual stimuli over the postural balance; Methods. The methods used: 1. The AMTI Netforce platform (Hardware and Software), 2.Using the postural balance measurement from AMTI Netforce for: a) eyes opened no aiming point, b) eyes opened with aiming point. Results. After the statistical analysis we have the following: a) for the initial test: MLI=152218.44, SDLI=113973.166 (for the trajectory length of center of gravity) and MAI=15328.81, SDAI=3465.370 (for the trajectory area of center of gravity); b) for the final test: MLF=5960.86, SDLF=5283.156 and MAF=2613.83, SDAF=1564.17. Conclusions. These results suggest that the visual control really does have an effect over the balance control of the tennis players. Specifically, our results suggest that when the subject has a visual way to control his posture, the balance control increases.
