A comparison of perceptual anticipation in combat sports between experts and non-experts: A systematic review and meta-analysis

Abstract

In order to systematically evaluate perceptual anticipation between experts and non-experts for different kinds of combat sports, we needed to perform a comprehensive assessment. In this systematic review and meta-analysis, we searched four English-language and three Chinese-language databases that used expert/non-expert research paradigms, to explore perceptual anticipation in combat sports. We employed a random effects model for pooled analyses using the inverse variance method. We included 27 eligible studies involving 233 datasets in this meta-analysis. We observed large effect sizes for the differences between experts and non-experts in both response accuracy (1.51; 95% CI: 1.15 to 1.87, p < 0.05) and reaction time (-0.91; 95% CI: −1.08 to−0.73, p < 0.05). We also observed substantial differences between experts and non-experts in the mean duration of visual fixations per trial (1.51; 95% CI: −2.40 to −0.63, p < 0.05), but not in the visual fixation duration (0.16; −061 to 0.92, p = 0.69). Taken together, high-level combat athletes have more advantages in perceptual anticipation than lower-level athletes, showing faster and more accurate responses when facing the opponent's attacks, as well as focusing on fewer points of visual fixations than novice athletes. Different types of combat sports and stimulus presentations affect perceptual anticipation abilities to varying extents in relation to outcome measures, with more pronounced expertise in a stimulus that is closer to real-world situations.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42021226343, PROSPERO CRD42021226343.

Space-time mapping relationships in sensorimotor communication during asymmetric joint action

“…Importantly, the formation of these space–time mapping relationships by message senders was not predetermined with message receivers but emerged spontaneously within group dynamics ( Grasso et al, 2022 ). This finding underscored the substantial influence of previous sensorimotor experiences on group behavior ( Zhang et al, 2022 ).…”

Exploring the effects of 3D-360°VR and 2D viewing modes on gaze behavior, head excursion, and workload during a boxing specific anticipation task

“…Examining the specific locations participants were looking at in each condition would have provided a more detailed comparison. Previous research has demonstrated that experts in boxing ( Martínez de Quel and Bennett, 2019 ) and combat sports ( Zhang et al, 2022 ) utilize specific areas of interest during visual exploration. Experts tend to distribute their gaze more towards areas such as the head and trunk of the opponent, while novices tend to focus more on the forehand and pelvis regions.…”

The effectiveness of the use of rhythmic stimulation to improve the speed of reaction and technical and tactical preparedness of qualified boxer

“…Проте дослідження та розробка методології використання засобів тренування боксерів на основі ритмічності як однієї з характеристик рухової діяльності мають фрагментарний характер Визначено, що отримані дані не мають суттєвих протиріч з наявними в нещодавніх дослідженнях . Проте, зафіксовані показники дещо відрізняються щодо виявлених у літературі Zhang, et al, 2022) Дослідники не мають протиріч щодо важливості підвищення швидкості рухів боксерів як запоруки технічного вдосконалення (Bingul, et al, 2018;Chen, et al, 2021). Навіть виділяючи окрему типологічні групу бійців, що досягають високої результативності двобою за рахунок швидкісних здібностей (Aksutin, & Korobeynikov, 2014).…”
