Abstract Binocular vision is the most important visual cue for spatial orientation in many sports. In this study, we investigated how binocular was influenced by an eye training program that may be used to improve individual’s oculomotor function. The experiment involved twenty-four female student athletes from team ball sports (soccer, basketball, handball). After initial testing session, 12 participants were randomly allocated experimental group. Optometric investigation which included...

Eye were recorded series five throws real-time conditions. The number...

The ability to quickly locate objects within the visual field has a significant influence on athletic performance. Saccades are conjugate eye movements responsible for rapid shift that brings new part of into foveal vision. aim this study was investigate effects sport expertise and intense physical effort saccade dynamics during free-viewing search task in skilled soccer players. Two groups male subjects participated study: 18 players non-athletes as control group. sessions tasks without...

Reactive agility (RA) directly refers to athletes’ visuomotor processing of the specific conditions for team sports. The aim study was identify factors among age, gender, sport discipline, time participation in a sports activity, reaction time, and visual field which could have an impact on visual-motor performance RA tasks young, competitive players. included boys (n = 149) girls 157) aged 13–15 participating basketball, volleyball handball. Anthropometric measurements were carried out,...

This longitudinal study investigated visual evoked potentials (VEPs) in 11 young female volleyball players who participated extensive training for 2 years. The control group consisted of 7 age-matched students were not involved any regular sports activity. Recordings VEPs performed twice: baseline recording (i.e., before began) and after years systematic, volleyball-specific athletic training. effect on signal conductivity was assessed by the latency N75, P100 N135 components waveform....

Experienced and less experienced soccer players were compared in terms of their gaze behavior (number fixations, fixation duration, number regions, distribution fixations across specific regions) during frontal 1 vs. defensive situations. Twenty-four men (eight players, eight non-players) watched 20 video clips. Gaze was registered with an Eye Tracking System. The scenes analyzed frame-by-frame. Significant main effect the group (experience) observed for regions. had a lower regions than...

Abstract We assessed the effect of physical effort with increasing intensity on neural activity in visual pathway volleyball players (n = 10) and non-athletes 10). Participants performed three 10-min tests a cycle ergometer. Each participant was assigned individual workloads below lactate threshold (40% [Vdot]O2max), at (65–75% above (80% [Vdot]O2max). Four recordings evoked potentials were made: pre-exercise immediately after each subsequent tests. by examining amplitude latency N75, P100,...

This study examined the effect of physical exertion on gaze behavior during basketball shooting in both stationary and dynamic conditions.Thirteen skilled players performed two-point a 60 second fatigue protocol. Before after jump shot test, two free throws. Eye movements were registered using an SMI Mobile EyeTracker. The frequency all fixation points (number) duration motor phases determined frame-by-frame analysis.The type differentiated control: 1) fixations longer more frequent throws...

Abstract In this study, we conducted an experiment in which analyzed the possibilities to develop visual skills by specifically targeted training of search. The aim our study was investigate whether, for how long and what extent a program functions could improve involved 24 healthy students from Szczecin University who were divided into two groups: experimental (12) control (12). addition regular sports recreational activities curriculum, subjects group also participated 8-week with...

This study examined whether patients with glaucoma exhibit differences in eye-hand coordination tasks compared to age-matched normal-sighted control subjects. Twenty-eight moderate-to-advanced stages of and 28 subjects no ocular disease participated the study. The Motor Performance Series (MLS) Vienna Test System including aiming, linear tracking, tremor, tapping tests were used assess coordination. Monocular Humphrey Visual Field binocular Esterman estimate visual field (VF) defect...

The main aim of this study was to examine the mediating effect change direction speed (CODs) on reactive agility (RA) in female players participating different team sports (TS). In total, there were 31 elite from Polish national basketball (n = 12, aged 24.98 ± 3.38) and handball 19, 27.34 4.68) teams participated study. Two experiments using 'five-time shuttle run gates' test with similar movement patterns used determine players' RA CODs. A simple mediation model utilised investigate...

Sensorimotor adaptability facilitates adjusting behaviour for changing environmental stimuli to maintain appropriate goal-directed motor performance. Its effectiveness is associated with perceptual-cognitive modulation. As the factors affecting it are still not completely known, aim of our study was therefore analyse association between selected variables (demographic, training, anthropometric, genetic) and sensorimotor adaptation in reactive agility tasks youth team-sport athletes. The...

This study examined postural control during single leg stance test with progressively increased balance-task difficulty in soccer players unilateral transfemoral amputation (n = 11) compared to able-bodied 11). The overall stability index (OSI), the anterior/posterior index, and medial/lateral three balance tasks increasing surface instability were estimated. oculomotor visuomotor contribution disabled athletes was analyzed. Oculomotor function, simple choice reaction times, peripheral...

Background The ability to track multiple objects plays a key role in team ball sports actions. However, there is lack of research focused on identifying object tracking (MOT) performance under rapid, dynamic and ecologically valid conditions. Therefore, we aimed assess the effects manipulating postural stability MOT performance.
