Sixteen participants performed basketball throws while EEG and MoCap systems recorded data on movement mechanics and neural activity. Biomechanical findings revealed that successful trials were characterized by refined movements, reduced wrist extension, increased elbow flexion, and more stable foot positioning compared to unsuccessful trials (all p > 0.05), contributing to greater shot accuracy. Reduced movement variability in successful trials further indicated improved motor consistency, reflective of skill development. EEG results showed higher beta and gamma power in the temporal lobe during successful compared to unsuccessful trials (p < 0.05), suggesting increased engagement in visuomotor integration and neural efficiency. Notably, our novice participants demonstrated limited neural efficiency in frontal regions (p > 0.05), potentially due to cognitive interference and self-monitoring. These findings highlight the importance of coordinated biomechanical execution and neural efficiency in optimizing basketball performance. The insights gained have practical implications for designing training interventions that improve motor performance, particularly for novice athletes.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"1-18"},"PeriodicalIF":1.1,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144660929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This effect has been leveraged as support for functional equivalence, where an internal representation can be shared for execution and imagery. However, times tend to rise exponentially more for imagined, compared to executed, movements, which could be attributed to the time spent within a task. Fifteen participants attempted execution and imagery of a reciprocal aiming movement between two targets that assumed different levels of ID (4, 5, 6 bits). They did this either over 3 or 5 cycles of movement to generate short- and long-duration movements, respectively. Mean times and time-ID slope/gradient coefficients revealed that the time within imagery was generally no longer than execution. However, the rise in time as a function of ID tended to be even greater when undertaking 3 compared to 5 cycles within imagery, but not execution. Overall, these findings may counter the suggestion that time spent within imagery is positively related to duration. However, further research is perhaps warranted to help formulate broader recommendations for imagery across different durations.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"1-9"},"PeriodicalIF":1.1,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144576842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated how variations in the relative articulatory demands during speech production-termed \"oral-motor complexity\"-affect postural center of pressure (COP) patterns among PwS, both with communication disorders (PwS-CDis) and without (PwS). Three groups of adults (PwS, PwS-CDis, and a nondisabled Control group) stood on a force platform while completing four 30-second quiet stance trials, followed by twelve 30-second trials randomized across three experimental conditions of varying oral-motor complexities (\"ba\", \"puh tuh kuh\", \"rah shah lah nah\"). COP variability (SD) was significantly higher during experimental conditions compared to quiet stance, regardless of group and movement plane. Differences in nonlinear time-dependent metrics were found across oral-motor task conditions, particularly among PwS-CDis, suggesting oral-motor complexity may influence underlying postural-motor organization. Distinct temporal-dynamical patterns observed in PwS-CDis indicate a possible link between pathology, postural control, and speech motor tasks, which is relevant when evaluating postural control in individuals with stroke-related communication disorders.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"1-16"},"PeriodicalIF":1.1,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144530804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the effects of VR-based OKS on head and trunk instability while standing on a continuous sinusoidal moving platform. Sixteen healthy adult males participated. Six experimental conditions combined three visual conditions (eyes open, eyes closed, VR-based OKS) with two platform frequencies (0.5 Hz, 1.0 Hz). Head and trunk accelerations were recorded using inertial measurement units, and root mean square values were analyzed. Cross-correlation between head and trunk sway was assessed. VR-based OKS induced significantly greater lateral trunk sway compared to the eyes-open condition (p = 0.003). Cross-correlation analysis showed a significant association between lateral head and trunk sway under OKS, with a moderate correlation at 0.5 Hz (r = 0.540, p < 0.05) and a strong correlation at 1.0 Hz (r = 0.793, p < 0.01). VR-based OKS dynamically alters sensory reweighting, inducing synchronized head-trunk movements. These findings highlight the potential use of VR-based OKS in vestibular rehabilitation and underscore the importance of adjusting stimulus intensity to suit individual needs. Further research should explore long-term adaptation effects.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"1-8"},"PeriodicalIF":1.1,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144499040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-density surface electromyography from the vastus lateralis (VL) was recorded and was decomposed into individual motor unit activities. The slope (MU slope) and intercept were calculated from the regression line between the individual motor unit recruitment thresholds and firing rates in each participant. Muscle thickness of the VL and vastus intermedius and echo intensity of the VL were evaluated using ultrasonography. While sitting on a chair, they repeatedly opened and closed their legs to position their feet outside and within 30-cm interval lines rapidly for 20 s. The mean steps were associated with echo intensity (r = 0.388, p < 0.01). Step variability was associated with the MU slope (r = 0.324, p = 0.03).

A total of 84 healthy participants (42 young adults, 23.02 ± 2.91 years; 42 older adults, 23.02 ± 2.91 years) were instructed to walk while carrying a filled cup without spilling. Walking speed (comfortable, fast) and attentional focus (internal, external, none) were systematically varied. Inertial sensors captured gait speed, cadence, step duration, step length, and pelvis acceleration variability, while spillage was measured in grams. A generalized linear model with bootstrap resampling (α = 0.05) examined the effects of focus, walking speed, and group. Results indicated that young adults walked faster than older adults (p < 0.001), and speed decreased from single-task to dual-task (p = 0.003) and from fast walking to comfortable walking (p < 0.001). No significant effect of attentional focus was found (p ≥ 0.056). The interaction between focus and speed was significant only for spillage (p = 0.041), showing an unimportant difference in spillage between fast walking without focus instructions (398.85 g) and with external focus instructions (399.76 g) (p = 0.030).
