- Visual Patterns of U16 athletes and professional basketball playersPublication . Marques, Rui; Dias, Gonçalo; M. L. Martins, Fernando; Gomes, Ricardo; Mendes, Rodrigo; Martinho, Diogo V.; Coelho-e-Silva, M. ou Coelho-e-Silva, M.J. ou Coelho-Silva, M ou Silva, M.; Mendes, RuiThis work aimed to compare the visual patterns of under 16 (U16) athletes and professional basketball players. The sample was composed of 10 U16 (aged 15.2 ± 0.4 years; 7.1 ± 2.5 years of experience) and 10 professional (aged 27.6 ± 3.7 years; 18.4 ± 4.6 years of experience) basketball players. All athletes were males and right-handed. Each participant performed 50 jump shots from 10 different positions and 5 different angle shots (0°, 45°, 90°, 135° and 180°). Number of fixations, time of first and last fixation, total fixation duration and Quiet Eye (QE) time of all shots were analysed. Overall, results indicated that the U16 group showed greater within-group differences regarding shot positions, last fixation times, shot angles, and first and last fixation times. Additionally, the U16 group presented different visual strategies than those of professional players, with significant differences found for shooting positions and shot angles, particularly for shots performed on the left side of the field, and for QE times. In conclusion, our results add to the understanding that longer fixation times and longer QE time are associated with better jump-shot efficacy, and this relation is evident when comparing players of different age groups.
- The use of eye tracking glasses in basketball shooting : a systematic reviewPublication . Marques, Rui; M. L. Martins, Fernando; Mendes, Rui; Coelho-e-Silva, M. ou Coelho-e-Silva, M.J. ou Coelho-Silva, M ou Silva, M.; Dias, GonçaloSports performance is related to cognitive processes that precede the motor task to be developed. In this way, the coupling between visual information and motor behavior has a major importance in filtering the visual information, necessary to the accomplishment of the motor task to be executed, ignoring ‘accessory’ stimuli. In this field, this essay has the goal of achieving a systematic review about past studies in the context of basketball shooting. We bring to you some evidence that support the applicability and efficiency of Eye Tracking Glasses systems in the analysis of visual attention in basketball shooting, emphasizing the concept of Quiet Eye, interconnected with anxiety and occlusion of vision. The results of the studies demonstrate the importance of the use of Eye Tracking Glasses for the evaluation/intervention in the process of visual attention training related to efficiency in shooting.
