Visual information is thought to be a dominant information source when performing whole-body movements in gymnastics. Visual information can furthermore facilitate performance when being engaged in situations of interpersonal coordination that may occur in sports such as synchronized trampolining. The question arises, which body-related visual cues are most important in the emergence of behavioral synchronization between two gymnasts in synchronized trampolining? To address this question, advanced gymnasts were asked to synchronize their performance to video-sequences of a model gymnast, while body-related visual cues of the model gymnast were systematically manipulated. Results revealed, first that biological motion cues are more important than nonbiological motion cues, and second that the perceived motion of the arms seems to drive synchronicity in synchronized trampolining. It is stated, that biological visual information of the arms is a dominant visual information source when performing leaps in synchronized trampolining.

Eye, head, and body movements are thought to be functionally coupled in the performance of complex skills, such as somersaults with and without twists (Davlin et al. 2001; von Laßberg et al. 2014). Directing the gaze to specific locations in the environment during the takeoff phase in somersaults could influence takeoff kinematics and, as a consequence, the subsequent flight phase. The goal of this study was to investigate the relationship between gaze direction during takeoff and the corresponding movement kinematics when performing backward somersaults in cheerleading. N = 11 cheerleaders performed standing backward somersaults in three experimental conditions (straight gaze direction, elevated gaze direction, depressed gaze direction). Results revealed that cheerleaders exhibited a larger hip angle during takeoff and longer flight duration of the somersaults when their gaze was elevated during the takeoff phase, thereby supporting the notion that a functional coupling seems to operate between gaze behaviour and motor behaviour in cheerleading. In daily practice, cheerleaders could try to focus their gaze on a point on the wall in front of them during the takeoff phase in somersaults in order to facilitate the development of a functional coupling between gaze behavior and motor behavior.

There is a significant complexity of movements and an ability to adapt to changing situations during a match, hence, a factor which decides about sports rank of a player is their motor fitness. The assessment of muscle power output and abilities of coordination in high-rank players can be one of the most essential model indicators either in the process of athlete selection or in the process of sports training. The research question is: How the measured indicators of a somatic body construction and motor fitness condition the sports level of volleyball players who specialize in different tactical functions? The paper demonstrates the test results of 12 volleyball players from MKS Muszynianka – a vice-champion of Poland in 2009. Basic features of a somatic body construction were measured; the indicators of muscle dynamic strength, visual perception and visual-motor coordination were tested. The comparative analysis of the applied somatic and fitness indicators in the study explains both the model of choice of tactical specializations in the game and sports hierarchy of volleyball players at championship level. Lengthwise predispositions of a body construction are prominent in the model; however, fitness skills (muscle dynamic strength and visual-motor coordination) may well compensate for insufficient somatic indicators.

Several recent studies designate that individuals with type-1-diabetes (T1D) are at higher risk for cognitive impairment than their peers without T1D. The aim of this study was to determine whether socio-demographic and clinical characteristics, eating attitude and psycho-emotional characteristics can predict visual perception (VP) and working memory (WM) impairment in the Moroccan population with T1D. A cross-sectional analysis was carried out in adult T1D patients (N=140). The Rey-Osterrieth Complex Figure test (electronical version) was used to evaluate the VP and WM. Moreover, patients also completed the 21-item Depression, Anxiety, and Stress Scale to assess their mental health state. In order to evaluate the risk of eating disorders the Eating attitudes Test-26 were used. Finally, anthropometric properties and clinical characteristics were evaluated. Predictors of cognitive dysfunction were determined using the hierarchical regression analysis. The major result was that age, long diabetes duration, glycemia, HbA1c, dieting and bulimia were the potential predictors of low scores in VP and WM. Other significant predictors were cholesterol, triglycerides for visual perception. Although psych-emotional symptoms including stress, anxiety, and depression were not a significant predictors of VP and WM impairment. Furthermore, our findings showed that the more the level of stress increases, the VP and WM scores significantly decrease. This study suggests that it can be helpful for medical practitioners to screen for disordered eating behaviors and emotional symptoms as a supplemental risk factor for cognitive impairment in T1D.

The present study has been conducted to investigate the visuospatial constructive cognition and memory among healthy students, as measured by the Rey Complex Figure Test (RCFT). We have compared the data used to draw the figures with the hypothesis that gender and physiological measurements have an impact on neuropsychological skills. One hundred twenty-five students (43 male, 82 female; age 18–32 years) participated in this study with a computerized numerical recording of the digital plot of the RCFT and a set of socio-demographic variables. Results revealed that visual perception and working memory were impacted by social and health determinants. Additionally, this study presents evidence supporting the implication of resting heart rate (RHR) and organizational strategy in working memory performance. Gender effect seems to be significant in physical and physiological differences. Regression analyses revealed a relevant contribution of study institution and sleep time on RCFT Copy score; RCFT Memory predicted by drawing from memory strategy, RHR, periodic medication use and marital status.

The basketball jump shot as a movement, allowing visual feedback based corrections, can be considered as a generalized or a specialized motor skill. The purpose of this study is to look into the connection between visual perception and the specialization of a motor skill. Therefore, six male basketball players were asked to perform jump shots under different viewing conditions from their favourite spot (sweet spot) and a second, middle-distance spot. The question was, if performance is affected by the changed visual conditions and whether the shooting spot plays a role in a potentially change in performance. The different visual conditions were first, a regular basketball hoop with no adjustment, second a regular basketball hoop with a covered backboard, and third a regular basketball hoop with a covered rim. Between the different visual conditions, performance did not differ significantly, neither from the sweet spot, nor from the neutral defined spot. However, players showed a significantly better performance from sweet spot than from the neutral spot under regular viewing conditions.

Introduction. The efficient collection and analysis of information from both the central and the peripheral field of vision may affect human coordination motor abilities. An analysis of the literature on the subject suggests that coordination motor abilities interact with one another, and it is only their combined effect that allows athletes to achieve technical mastery. The main aim of the study was to assess specific coordination motor abilities and to determine how visual perception and reaction time correlate with time-movement anticipation in elite female basketball players. Material and methods. The study participants comprised 17 female basketball players from the Polish National Team aged 18.1 ± 0.8 years. The study involved three ability tests from the Vienna Test System: the Reaction Test (RT, S1), the Peripheral Perception test (PP), and the Time/Movement Anticipation test (ZBA, S2). Results. The analysis of the results obtained proves that the best-developed ability in participants is reaction time, while the other abilities show average development. Study participants were able to develop their response abilities to such high levels by means of practice. A correlation coefficient was found between motor time and tracking deviation (r=0.56), and between time anticipation and the number of correct responses to stimuli appearing in the left (r=0.92) and right (r=0.88) field of vision. Athletes who achieved better results in time anticipation omitted fewer visual stimuli (r=0.7) in the peripheral field of vision. Statistically significant correlations were observed between movement anticipation and reaction time to stimuli in the central field of vision (r=0.58). Conclusions. Perception abilities have a significant effect on time anticipation. The range of one's field of vision does not determine the reaction time to a visual stimulus. Perception efficiency and divided attention, in conjunction with time and movement anticipation, create a complex of specific psychomotor abilities that is indispensable for achieving success in team sports.
