“…In reality, the attacks were often recognized in movement stage 2 (flight phase during shortening of the distance), while in VR, they were recognized more often also in movement stage 3 and 4 (landing phase after the flight phase and main phase of the attack). These results are in line with a previous work [22].…”

“…When subtracting 150 ms, the relevant movement stages were most often movement stage 3 and 4, but when subtracting 255 ms and 370 ms, the movement stages which contain relevant signals were in most cases movement stage 2. Therefore, we can support the results of Petri et al that the reduction of distance seems to be an important signal to recognize an upcoming attack [19,22]. As long as the sports specific reaction times Table 2.…”

“…To analyze the anticipatory signals, in which the athletes recognized the upcoming attacks, we divided the attacks in four movement stages (MS 1 -MS4) according to previous reference [22]. The following classification (Table . 1) is valid for both attacks (GZ and KZ).…”

Virtual reality (VR) is an often-used instrument in sports science research and practical training. However, VR studies with experienced athletes and sports specific tasks are rare. Furthermore, the transfer from interventions in VR into reality is even less investigated. It is possible to analyze benefits of VR using in-situ studies comparing human behavior in VR with reality. If no differences occur in the human behavior, then VR would be appropriate for interventions to improve athletes’ performance. Therefore, we let seven karate athletes respond each to ten attacks of a real attacker (reality) and a virtual attacker (VR using a Head Mounted Display) and compared the parameters “response quality” and “attack recognition” under both conditions. As attacks we chose Gyaku-Zuki (reverse punch, GZ) and Kizami-Zuki (attack with the front arm, KZ). ANOVAs and sign tests showed isolated cases of significant differences between both conditions: response quality in KZ, and attack recognition for 150ms in GZ, all p0.05). The remaining comparisons showed no significant differences (p>0.05). We conclude that further research is needed but the results of the present pilot study are promising to assume that VR is suitable for applications because similar performance outcome in reality and VR were obtained.

“…Future studies need to further specialize the type of stimulus/stimuli in their experimental task. Using simulation training, setting realistic situation and creating in-situ stimulus could give beginners more specific and helpful recommendation to improve their visual search behavior (Petri et al, 2017 , 2020 ). Besides, future studies should focus on other variables associated with perceptual anticipation in sports, such as quiet eye and microsaccades.…”

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.
