Twenty-four players (11.8 ± 1.6 years) were randomly assigned to a Short-Rest group (0 s between trials, 10 s between series, consecutive-day sessions) or a Long-Rest group (10 s between trials, 30 s between series, nonconsecutive-day sessions). Both groups completed 12 practice sessions over six weeks. Serve efficacy (percentage of successful serves) and accuracy (radial error) were assessed at pretest, post-test, and retention. Both practice schedules showed similar descriptive improvements in serve efficacy from pretest to post-test, with no significant effects of group, time, or interaction. Although the Short-Rest group exhibited a decline at retention and the Long-Rest group showed more stable performance, these differences were not statistically significant. No between-group differences were found for serve accuracy. A within-group decline from pretest to post-test was observed only in the Long-Rest condition. Overall, when practice volume was controlled, rest distribution did not produce significant differences in acquisition or retention. Descriptive trends suggesting greater stability with longer rest intervals should be interpreted cautiously.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"636-646"},"PeriodicalIF":1.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148820012","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}

Cognitive functions were assessed in three domains: mental rotation, spatial orientation, and visuospatial working memory. The associations between balance scores and spatial cognitive scores were evaluated using Spearman's rho correlation coefficient and linear regression analysis. Statistically significant correlations were identified in the relationship of spatial orientation and static balance as well as mental rotation and dynamic balance. No significant correlation was observed in case of visuospatial working memory.

Although clinical symptoms emerge only after considerable neural damage, subtle motor deficits may exist in asymptomatic individuals. This study aimed to identify such subclinical motor alterations by examining multi-finger coordination in professional welders. Nine professional welders with more than 20 years of welding experience and ten age-matched healthy controls participated in the study. Participants performed three isometric finger force tasks: a maximal voluntary contraction task to assess maximal finger forces, a single-finger ramp task to evaluate finger enslaving, and a multi-finger quick pulse task to analyze motor synergies and anticipatory synergy adjustments (ASA). Surface electromyogram was recorded to quantify muscle co-contraction. Compared to controls, welders exhibited reduced motor synergy strength, delayed and decreased ASA, and increased antagonist muscle co-contraction. These findings suggest that long-term occupational welding exposure, which involves manganese as a major component, is associated with subtle but measurable alterations in motor coordination and neural control strategies, even in the absence of clinical symptoms. Multi-finger synergy analysis and co-contraction metrics may serve as sensitive markers for detecting early motor dysfunction in populations occupationally exposed to neurotoxic substances.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"218-229"},"PeriodicalIF":1.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147500395","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}

Juggling provides a useful model for studying changes in speed and accuracy during skill acquisition. Seventy-four participants practiced 3-ball cascade juggling for 12 min each day for 18 days. On each day, we recorded the number of catches and the duration of each trial by the end of practice. Performance was evaluated using the number of catches and trial duration, from which accuracy was quantified as the probability of successfully catching a tennis ball and speed was quantified as juggling frequency. Over 18 days, participants improved accuracy from 0.67 to 0.91 in a decelerating pattern. Males were 16% more accurate than females on each day of practice. After adjusting for hand size, both genders showed similar accuracy. Juggling speed increased from 1.2 to 2.3 Hz, with no significant gender differences in 15 out of 18 days. These findings provide a probabilistic framework for characterizing skill acquisition in continuous motor tasks with cyclic and repetitive movement patterns and may help identify sensory and motor deficits in the upper extremities.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"593-602"},"PeriodicalIF":1.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148521487","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 aimed to clarify the neurophysiological and behavioral effects of combining gaze stabilization exercise (GSE) and cerebellar cathodal tDCS on LVST excitability and postural sway. Fourteen healthy adults participated in this randomized crossover study comparing GSE with sham stimulation and GSE with cerebellar cathodal tDCS. The center of pressure (COP) total trajectory length, rectangular area, and LVST excitability were measured before and after each intervention. LVST excitability was evaluated using the galvanic vestibular stimulation-conditioned H-reflex (GVS-H). Both stimulation conditions significantly reduced COP total trajectory length compared to baseline, suggesting that the GSE intervention effectively improved postural stability. However, no significant interaction effects were observed for either GVS-H or the COP rectangular area. Therefore, although GSE effectively reduces postural sway, combining GSE with cerebellar cathodal tDCS provides no further benefit or LVST modulation. This study underscores the established effectiveness of GSE alone.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"549-556"},"PeriodicalIF":1.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148425900","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}

Thirty right-handed participants (15 younger, 15 older adults) performed one- and two-target aiming tasks under vibrotactile (VT), auditory (A), and no-feedback (NF) conditions. Results showed that reaction time was shorter in the two-target task than in the one-target task under VT feedback (p = .002). Older adults demonstrated significantly shorter movement times with VT than with NF. Older adults showed greater undershooting in the two-target task under NF, which was reduced with VT feedback (p = .011). Additionally, older adults typically spent longer in the time after peak velocity, but VT feedback significantly reduced this duration. Overall, VT feedback improved both temporal and spatial measures, particularly for older adults. Auditory feedback showed limited effects, influencing only TAPV1 (p = .036). Together, these results highlight the potential of VT feedback to mitigate age-related motor performance declines.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"164-173"},"PeriodicalIF":1.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147286175","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}

Participants completed four walking conditions: normal walking, walking with an internal focus, walking with an external focus, and walking while performing a cognitive dual-task (counting backward from 100). Kinematic data were recorded using a Vicon motion capture system and analyzed using Python. Key outcome measures included spatial-temporal gait parameters, local dynamic stability assessed via the Lyapunov exponent, and motor variability based on the uncontrolled manifold (UCM) framework. Repeated measures ANOVA and post hoc tests revealed that attentional focus and cognitive load significantly influenced walking patterns. Dual-tasking led to slower gait speed, increased step width, and a higher percentage of double support, alongside increased Lyapunov exponents and decreased UCM indices-indicating reduced gait stability and adaptability. Conversely, external focus improved most gait parameters. These findings highlight the critical role of attentional strategies in maintaining gait stability and suggest their relevance in motor control, learning, and rehabilitation programs.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"174-183"},"PeriodicalIF":1.3,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147436979","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}
