The main aim of the master's thesis was to determine the importance of visual functions in the basketball shot from the spot (free throw shot). The emphasis was placed on the importance of the influence of visual feedback, the influence of emphasized eye focus on the ring before the shot is taken, and the influence of visual acuity on performance. The study included 15 senior basketball players with basketball experiences in the 2nd and 3rd SKL (age 24 ± 4 years, body height 188 ± 7 cm, body weight 85 ± 8 kg). The selected basketball players performed 20 free throws in 6 different conditions. Statistical analysis of the data revealed that there were no statistically significant differences in performance between free throws in normal conditions and free throws in difficult conditions, except when the performance in free throws in normal conditions and performance in free throws without visible information (blindfolded) was performed. Although no statistically significant differences were found, it turned out that the players were, on average, less successful in all the throws they performed in difficult conditions. The assumption, that players who are on average more successful in free throws in normal conditions are also more successful in free throws in difficult conditions, was confirmed. The completed research can be a reason for a more detailed, accurate and technologically more sophisticated analysis of the impact of visual functions, specially the emphasized visual focus on a basketball shot.
