A meta-analysis of performance advantages on athletes in multiple object tracking tasks

This study compared the multiple object tracking (MOT) performance of athletes vs. non-athletes and expert athletes vs. novice athletes by systematically reviewing and meta-analyzing the literature. A systematic literature search was conducted using five databases for articles published until July 2024. Healthy people were included, specifically classified as athletes and non-athletes, or experts and novices. Potential sources of heterogeneity were selected using a random-effects model. Moderator analyses were also performed. A total of 23 studies were included in this review. Regarding the overall effect, athletes were significantly better at MOT tasks than non-athletes, and experts performed better than novices. Subgroup analyses showed that expert athletes had a significantly larger effect than novices, and that the type of sport significantly moderated the difference in MOT performance between the two groups. Meta-regression revealed that the number of targets and duration of tracking moderated the differences in performance between experts and novices, but did not affect the differences between athletes and non-athletes. This meta-analysis provides evidence of performance advantages for athletes compared with nonathletes, and experts compared with novices in MOT tasks. Moreover, the two effects were moderated by different factors; therefore, future studies should classify participants more specifically according to sports levels.

Altered spontaneous regional brain activity in ventromedial prefrontal cortex and visual area of expert table tennis athletes.

Sports training may lead to functional changes in the brain, and different types of sports, including table tennis, have different influences on these changes. However, the effects of long-term table tennis practice on brain function in expert athletes are largely undefined. Here, we investigated spontaneous regional brain activity characteristics of expert table tennis athletes by using resting-state functional magnetic resonance imaging to compare differences between 25 athletes and 33 age- and sex-matched non-athletes. We analyzed four metrics-amplitude of low-frequency fluctuation (ALFF), fractional ALFF, regional homogeneity, and degree centrality-because together they identify functional changes in the brain with greater sensitivity than a single indicator and may more comprehensively describe regional functional changes. Additional statistical analysis was conducted to assess whether any correlation existed between brain activity and years of table tennis training for athletes. Results show that compared with non-athletes, table tennis athletes showed altered spontaneous regional brain activity in the ventromedial prefrontal cortex and the calcarine sulcus, a visual area. Furthermore, the functional changes in the calcarine sulcus showed a significant correlation with the number of years of expert sports training. Despite the relatively small sample size, these results indicated that the regional brain function of table tennis athletes was associated with sports training-related changes, providing insights for understanding the neural mechanisms underlying the expert performance of athletes.

Virtual training, real effects: a narrative review on sports performance enhancement through interventions in virtual reality.

The present article reports a narrative review of intervention (i.e., training) studies using Virtual Reality (VR) in sports contexts. It provides a qualitative overview and narrative summary of such studies to clarify the potential benefits of VR technology for sports performance enhancement, to extract the main characteristics of the existing studies, and to inform and guide future research. Our literature search and review eventually resulted in 12 intervention studies with a pre vs. post design focused on different sports, including target and precision sports (archery, bowling, curling, darts, golf), bat/racquet and ball sports (baseball, table tennis), goal sports (football/soccer, basketball), martial arts (karate), and sport-unspecific processes such as bodily sensations and balancing. The samples investigated in the primary studies included novice, amateur, and expert athletes (total aggregated sample size N = 493). Many studies found statistically significant effects in relevant target skills following interventions in VR, often outperforming training effects in passive or active control conditions (e.g., using conventional training protocols). Therefore, interventions in VR (or extended reality) have the potential to elicit real effects in sports performance enhancement through training of motor and psychological skills and capabilities in athletes, including perception-action skills, strategic, tactical and decision-making, responding to unexpected events, and enhancing psychological resilience and mental performance under pressure. The neurocognitive mechanisms (e.g., visual search behavior, imagery), methodological aspects (e.g., adaptive training difficulty), and the issues of real-world transfer and generalizability via which these potential sports-performance-related improvements may occur are discussed. Finally, limitations of the present review, the included studies, the current state of the field in general as well as an outlook and future perspectives for research designs and directions are taken into consideration.

Vision and sports: An overview

Background: Visual skills and their components are thought to be responsible for much of the manner whereby athletes obtain information about the sporting environment. The field of sports vision deals with the vision care services that are provided to athletes. If visual skills of athletes are not assumed as natural attributes, they should be assessed and be subjected to training according to need. Studies have shown that the visual abilities of the athletes can be divided into software and hardware visual skills, and it is the software visual skills that separate expert athletes from non-experts.Aim: The study aims to collate (1) studies that show the importance of visual skills in sports performance, (2) studies that show that visual skills are trainable and (3) studies that show the effect of training on the visual skills and performance in sports.Method: An extensive search of literature was performed on studies that supported the importance of vision in sports performance. Also included were studies that supported the transfer of improved visual skills to improved performance on the field of play.Results: There is literature that supports the significance of visual skills in sport. There is also literature that attempts to show evidence that improved visual skills can improve performance on the field of play.Conclusion: Sports vision practitioners need to develop standardised testing and training protocols for visual skills. Standard protocols will harmonise the development of visual skills norms.Contribution: Literature has shown the importance of vision in sports performance. Literature has also shown that improved visual skills can improve performance on the field of play. The current paper is an attempt at calling for the development of standardised protocols and norms for sports vision training.

Characteristics of changes in the functional status of the brain before and after 1,000 m all-out paddling for different levels of dragon boat athletes.

Dragon boat is a traditional sport in China, but the brain function characteristics of dragon boat athletes are still unclear. Our purpose is to explore the changing characteristics of brain function of dragon boat athletes at different levels before and after exercise by monitoring the changes of EEG power spectrum and microstate of athletes before and after rowing. Twenty-four expert dragon boat athletes and 25 novice dragon boat athletes were selected as test subjects to perform the 1,000 m all-out paddling exercise on a dragon boat dynamometer. Their resting EEG data was collected pre- and post-exercise, and the EEG data was pre-processed and then analyzed using power spectrum and microstate based on Matlab software. Post-Exercise, the Heart Rate peak (HR peak), Percentage of Heart Rate max (HR max), Rating of Perceived Exertion (RPE), and Exercise duration of the novice group were significantly higher than expert group (p < 0.01). Pre-exercise, the power spectral density values in the δ, α1, α2, and β1 bands were significantly higher in the expert group compared to the novice group (p < 0.05). Post-exercise, the power spectral density values in the δ, θ, and α1 bands were significantly lower in the expert group compared to the novice group (p < 0.05), the power spectral density values of α2, β1, and β2 bands were significantly higher (p < 0.05). The results of microstate analysis showed that the duration and contribution of microstate class D were significantly higher in the pre-exercise expert group compared to the novice group (p < 0.05), the transition probabilities of A → D, C → D, and D → A were significantly higher (p < 0.05). Post-exercise, the duration, and contribution of microstate class C in the expert group decreased significantly compared to the novice group (p < 0.05), the occurrence of microstate classes A and D were significantly higher (p < 0.05), the transition probability of A → B was significantly higher (p < 0.05), and the transition probabilities of C → D and D → C were significantly lower (p < 0.05). The functional brain state of dragon boat athletes was characterized by expert athletes with closer synaptic connections of brain neurons and higher activation of the dorsal attention network in the resting state pre-exercise. There still had higher activation of cortical neurons after paddling exercise. Expert athletes can better adapt to acute full-speed oar training.

A systematic review of ironic effects of motor task performance under pressure: The past 25 years

ABSTRACT Wegner's theory of ironic processes of mental control emphasizes how the implementation of cognitive load-induced avoidant instructions can cause inefficient motor cognition in sports, thereby inducing so-called ironic effects where an individual—ironically—does precisely what s(he) intended not to do. This systematic review synthesizes relevant existing research and evaluates the effectiveness of experimental manipulations and cognitive load measurements for investigating ironic effects on motor task performance under pressure conditions. This review identified twenty-four empirical studies published before January 2022, including studies with experimental (21%) and quasi-experimental (79%) within- and between-subject designs. The most common reported pressure (i.e., cognitive load) manipulations fell into two categories: anxiety (77%) and dual-task (33%) techniques. The review also identified positive action-oriented instructional interventions to reduce ironic errors. Although most reported findings supported Wegner's assumptions about ironic performance effects, the review also identified inconclusive evidence (8%), which indicates a need for more research with a greater focus on: robust experimental design; the inclusion of competitive stressors; expert athletes; elite athletes; and intervention-based studies. These additions will clarify the mechanisms of ironic effects and assist in the development of interventional programs to diminish the likelihood of ironic effects in sports performance.

An exploratory study on the effect of a four-week stroboscopic vision training program on soccer dribbling performance

BACKGROUND: Perceptual-cognitive skill is a crucial component of expert performance in sport as expert athletes rely on the integration and processing of sensory information to execute complex actions. One of the topics of interest to skill acquisition researchers is therefore how the perceptual-cognitive system can be trained, and how that affects sport skill performance. One of the methods suggested to be able to aid in the training of perceptual-cognitive skill is restricted visual feedback training. Recently, stroboscopic vision glasses have been proposed as a tool that can restrict visual feedback during sport training and may therefore provide a useful tool for training sport-specific skills.However, despite its use in practice, evidence for the beneficial effect of stroboscopic vision on sport-specific performance across youth athletes with a range of performance levels is currently lacking. AIM: Therefore, this study aimed to investigate the effect of a four-week soccer training program with (experimental group) or without (control group) stroboscopic vision on the dribbling performance of relatively fast and slow dribblers. METHOD: To measure dribbling performance, this study used the Ugent Soccer dribbling task. RESULTS: A Repeated Measures MANOVA revealed that four weeks of stroboscopic vision training did not improve soccer dribbling skill measured through the time taken to complete the dribbling task as well as the number of touches of the ball while dribbling. CONCLUSION: While stroboscopic vision can likely lead to short term changes in perceptual-cognitive skill, it is likely not related to persistent changes in soccer dribbling performance in youth soccer players.

Shot deception in basketball: Gaze and anticipation strategy in defence.

Anticipation of teammates and opponents is a critical factor in many sports played in interactive environments. Deceptive actions are used in sports such as basketball to counteract anticipation of an opponent. In this study, we investigated the effects of shot deception on the players' anticipation behaviour in basketball. Thirty one basketball players (15 expert, 16 novice) watched life-sized videos of basketball players performing real shots or shot fakes aimed at the basket. Four different shot outcomes were presented in the video stimuli: a head fake, a ball fake, a high shot fake, and a genuine shot. The videos were temporally occluded at three different time points (-160ms, -80ms, 0ms to ball release) during a shooting motion. The participants had to perform a basketball-related response action to either shots or shot fakes. Response accuracy, response time, and decision confidence were recorded along with gaze behaviour. Anticipation accuracy was reduced at later occlusion points for fake shooting actions. For expert athletes, this effect occurred at later occlusion points compared to novices. The gaze analysis of successful and unsuccessful shot anticipations revealed more gaze fixations towards the hip and legs in successful anticipations, whereas more fixations towards the ball and the head were found in shots unsuccessfully anticipated. It is proposed that hip and leg regions may contain causal information concerning the vertical trajectory of the shooter and identifying this information may be important for perceiving genuine and deceptive shots in basketball.

Visual Perception in Expert Athletes: The Case of Rock Climbers.

The purpose of the present study was to examine the visual perception system in expert climbers through a psychophysical optical test in a cross-sectional study. Twenty-seven male participants with an International Rock Climbing Research Association (IRCRA) best on-sight lead skill level ranging between 18 and 27 and a best red-point level ranging between 18 and 29 completed a series of psychophysical optic tests assessing their visual field, visual acuity, and contrast sensitivity. Climbers were divided by their best red-pointed lead level, and, following IRCRA recommendations, two groups were created: an advanced group (IRCRA redpoint level between 18 and 23), and an elite-high elite group (IRCRA redpoint level between 24 and 29). The elite group presented more training days per week (5.25 ± 1.28), best on-sighted lead level (24.63 ± 1.92 IRCRA), and best red-pointed lead level (26.63 ± 2.56 IRCRA) than the advanced group (3.67 ± 0.91 training days per week, 19.50 ± 1.04 IRCRA on-sighted level and 20.67 ± 1.57 IRCRA red-pointed level). Better visual perception outputs were produced by the group of elite climbers in visual field tests; no differences were observed between the two groups for visual acuity and contrast sensitivity tests. Overall, findings indicate that best climbers performed better at the visual perception tasks that tested their visual field. Such better perception from best climbers is discussed given (1) the greater time they spend coercing the visual system during practicing climbing and (2) the specific complexity of the stimuli as they are confronted to harder routes where holds are less perceptible and the time to find best hold sequences is constrained.

Elite Players Invest Additional Time for Making Better Embodied Choices.

Expert athletes are determined to make faster and better decisions, as revealed in several simple heuristic studies using verbal reports or micro-movement responses. However, heuristic decision-making experiments that require motor responses, also being considered as the embodied-choice experiments, are still underrepresented. Furthermore, it is less understood how decision time and confidence depend on the type of embodied choices players make. To scrutinize the decision-making processes (i.e., decision time, decision confidence), this study investigated the embodied choices of male athletes with different expertise in a close-to-real-life environment; 22 elite (Mage = 17.59 yrs., SD = 3.67), and 22 amateur (Mage = 20.71 yrs., SD = 8.54) team handball players performed a sport-specific embodied-choice test. Attack sequences (n = 32) were shown to the players, who had to choose between four provided options by giving a respective sport-specific motor response. We analyzed the frequencies of specific choices and the best choice, as well as the respective decision time and decision confidence. Elite and amateur players differed in the frequencies of specific choices (i.e., forward/tackling; passive blocking), and elite players made the best choice more often. Slower decision times of elite players were revealed in specific choices and in best choices, the confidence of decisions was rated equally high by both player groups. Indications are provided that elite players make better choices rather slower, instead of faster. We suppose this is due to specific sensorimotor interactions and speed-accuracy-tradeoffs in favor of accuracy in elite players. Our findings extend expert decision-making research by using an embodied-choice paradigm, highlighting considerations of decision time and confidence in future experiments.

Effect of gender, carrying and planting the pole on approach step parameters in young pole vaulters

In pole vaulting, take-off speed is considered as a major determinant of performance. Pole carriage could affect the speed acquired during the approach and at the take-off. This study investigated different types of runs performed randomly by young male and female expert athletes: maximal sprint, maximal pole carriage run, maximal run-up with simulated pole plant and competition situation. Speed profile was determined with a radar gun and spatiotemporal parameters were recorded for the last 20 m of the approach with the Optojump Next system. For both genders, mechanical variables were compared using two-way ANOVAs with repeated measurements. Pole carriage represents the main cause of speed decrease for both men (−5.8%) and women (−6.2%). A step rate decrease during pole carriage was pointed out with an increase of contact time for both men and women. Significant speed decrease was observed for women at the take-off compared to pole plant simulation (−4.3%), while not for men. Those results provide a new insight for pole vault training allowing to update training process with specific exercises leading to reduce speed loss at take-off.

Performance and decision making of a complex skill under monitoring and outcome pressure conditions: Which of them can reinvestment predict?

Despite a huge amount of research conducted on performance under competitive pressure, the different components of a competitive environment such as outcome pressure or monitoring pressure, have less been investigated. The present study aimed to investigate the performance and decision making of a complex skill and their link with reinvestment (a type of self-focus behavior) under different conditions of pressure using a table tennis task. The topspin forehand and backhand shots of 20 expert table tennis athletes were examined under low, monitoring, and outcome pressure conditions in a within-group design. In addition, predictive validities of Decision-Specific Reinvestment Scale (DSRS) and Movement-Specific Reinvestment Scale (MSRS) with the changes of performance and decision making from low- to high-pressure conditions as dependent variables were examined. The repeated measures ANOVA results showed that the effects of pressure conditions on anxiety were significant. Decision accuracy under outcome pressure and decision speed under monitoring and outcome pressure conditions were decreased. The performance of athletes was decreased under monitoring pressure while no changes was observed in their performance under outcome pressure. Decision Reinvestment (a factor of DSRS) could predict decision speed changes under both pressure conditions, while Movement Self-Consciousness (a factor of MSRS) could predict performance changes only under monitoring pressure. Our Findings highlight that the subscales of MSRS and DSRS were activated independently and a competitive pressure situation has different effects on the cognitive and motor aspects of complex skills. It is suggested that expert athletes and coaches consider separate pressure conditions and their relationships with the ongoing task.

Experts use base rates in real-world sequential decisions

Human behavior is often assumed to be irrational, full of errors, and affected by cognitive biases. One of these biases is base-rate neglect, which happens when the base rates of a specific category are not considered when making decisions. We argue here that while naïve subjects demonstrate base-rate neglect in laboratory conditions, experts tested in the real world do use base rates. Our explanation is that lab studies use single questions, whereas, in the real world, most decisions are sequential in nature, leading to a more realistic test of base-rate use. One decision that lends itself to testing base-rate use in real life occurs in beach volleyball—specifically, deciding to whom to serve to win the game. Analyzing the sequential choices in expert athletes in more than 1,300 games revealed that they were sensitive to base rates and adapted their decision strategies to the performance of the opponent. Our data describes a threshold at which players change their strategy and use base rates. We conclude that the debate over whether decision makers use base rates should be shifted to real-world tests, and the focus should be on when and how base rates are used.

Exploring the Gaze Behavior of Tennis Players with Different Skill Levels When Receiving Serves through Eye Movement Information

Background: The purpose of this study was to explore the gaze behavior of tennis players with different skill levels when receiving serves through eye movement information. Methods: The skill level was divided into group A (experts, with more than 10 years of playing experience) and group B (novices, with less than 2 years of playing experience). We compared the differences in gaze behavior between groups A and B at the head-shoulder, trunk-hips, arm-hand, leg-foot, racket, ball, and racket-ball contact area seven positions using the Eye-gaze Response Interface Computer Aid (ERICA) device. Data were analyzed using two-way ANOVA. Results: Compared with the novices, the experts have more gaze time in the head–shoulders, rack, and ball when serving forehand (p &lt; 0.01). The experts also have more gaze time on the head–shoulders, trunk–hips, racket, ball, and racket–ball contact area when serving backhand (p &lt; 0.05). Conclusions: Expert athletes have a longer stare time for a specific position, which mainly determines the direction of the ball. Tennis coaches can increase the gaze time for these four positions and improve tennis players’ ability to predict the direction of the ball.

Dissociable plasticity of visual-motor system in functional specialization and flexibility in expert table tennis players.

Specialization and flexibility are two basic attributes of functional brain organization, enabling efficient cognition and behavior. However, it is largely unknown what plastic changes in specialization and flexibility in visual-motor areas occur in support of extraordinary motor skills in expert athletes and how the selective adaptability of the visual-motor system affects general perceptual or cognitive domains. Here, we used a dynamic network framework to investigate intrinsic functional specialization and flexibility of visual-motor system in expert table tennis players (TTP). Our results showed that sensorimotor areas increased intrinsic functional flexibility, whereas visual areas increased intrinsic functional specialization in expert TTP compared to nonathletes. Moreover, the flexibility of the left putamen was positively correlated with skill level, and that of the left lingual gyrus was positively correlated with behavioral accuracy of a sport-unrelated attention task. This study has uncovered dissociable plasticity of the visual-motor system and their predictions of individual differences in skill level and general attention processing. Furthermore, our time-resolved analytic approach is applicable across other professional athletes for understanding their brain plasticity and superior behavior.

The 'Quiet Eye' and motor performance in basketball free throw shooting

Background and Study Aim. This study investigates expert and amateur basketball players' visual tracking strategies accuracy and inaccuracy free throws.&#x0D; Material and Methods. A total of 22 university student, 11 of whom were experts (n = 5 females, n = 6 males) and 11 amateurs (n = 5 females, n = 6 males), without visual impairment, participated the study. Each athlete performed a total of 10 throws. The normal distribution of data recorded in both accurate and inaccurate throws was checked with the Shapiro-Wilk test. All of the data received on accurate and inaccurate throws were analyzed by independent samples t-test.&#x0D; Results. Expert basketball players were recorded to have an average of 78% accurate throws out of 10, and as for amateur basketball players, they were recorded to have 34%. During accurate throws, the quiet eye durations of expert basketball players were identified as ~886ms, and quiet eye durations during inaccurate throws were as ~570ms. During accurate throws, the quiet eye durations of amateur basketball players were identified as ~612ms, and quiet eye durations during inaccurate throws were as ~388ms. The study's findings reveal that expert basketball players develop statistically longer quiet eye and fixation durations than amateur basketball players.&#x0D; Conclusion. The study's findings have supported the phenomenon of longer quiet eye durations during expert athletes' specific motor skills. The knowledge obtained from the study's findings is thought to have the utmost significance in identifying the quiet eye durations of expert basketball players and teaching their visual strategies to amateur level athletes to improve their performance.

Sport Practice Enhances Athletes' Observation Capacity: Comparing Scenic Change Detection in Open and Closed Sports.

Domain-specific knowledge guides our attention and thus influences our perception. Prior change-blindness research has shown that expert athletes can spot meaningful scene changes more quickly than novices, but less is known of whether this expertise is modulated differentially between open and closed sporting activities. We presented 81 individuals (20 gymnasts, 19 rock climbers, 22 parkour practitioners, and 20 control participants) with alternating sequences of images that corresponded to the habitual training landscapes of each group (gymnasiums, rock cliffs, and urban environments, respectively). We included contextual and non-contextual scenic changes to evaluate whether athletes were generally aware of their environments, or whether their observation strategies only targeted sport-related environmental elements. Among these three athletic endeavors, we found that gymnasts were faster at detecting changes in their environment, irrespective of whether or not these changes were contextual to the sports involved. Expert rock climbers presented a domain-specific expertise that was improved even further for contextual changes. Parkour practitioners presented the fastest reaction times in the urban environment and some of the best reaction times for all types of changes. These results confirm that an ability to read the environment is an integral aspect of practice in open-skilled sports, while skills of athletes in closed-skilled sports are more closely related to motor skill repetitions in constant environments. Thus, open skill training may benefit athletes' guidance of attention. Our finding that parkour practitioners appeared to have developed the widest perceptual abilities was probably linked to these athletes' extremely wide range of practice environments and with the constant demands of this sport to find solutions in random natural environments that that are not purposely designed for the sport.
