Eight sets of 25 continuous trials each were conducted. The force-tracking accuracy and electromyography (EMG) of extensor carpi radialis (ECR) and flexor carpi ulnaris (FCU) were evaluated. The force-tracking accuracy was compared between the phase (upward: generation and downward: relaxation), set (first and eighth), and within-set periods (early: 1-5, middle: 10-15, and late: 20-25 trials). The force-tracking accuracy at the middle and late periods significantly declined compared to the early period in the relaxation phase. Integrated EMG of ECR and FCU was significantly larger in the generation than in the relaxation phase. The integrated EMG of FCU in the generation phase was significantly different between the periods. Furthermore, the median frequency of FCU was significantly different between the phases and periods. These findings suggest that the effects of muscular fatigue on force control varied between generation and relaxation due to the amount and frequency band of muscle activity.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"333-344"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144048154","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}

The force control training utilized a visual-guided force tracking task with either a uniform or non-uniform sinusoidal wave in ankle plantar flexors (PF). Postural stability was assessed by measuring the center of pressure (COP) in a single-leg standing posture. Despite consistent repetitions, no significant differences in COP parameters were observed between the pre- and post-training assessments. However, significant differences were noted between the pre-training assessments and the post-training assessments conducted one week later, utilizing a randomized order. Shifting from a regimen of constant repetition to a randomized order has a positive impact on the transfer and retention of acquired motor skills.

In Free, participants uniformly selected the limb ipsilateral to the target. While success and subjective difficulty were not influenced by Choice, effort varied depending on Choice.

Twenty-two healthy participants engaged in eight postural control tasks: standing/crouching (Posture) × eyes opened/eyes closed (Vision) × light touch/no touch (Touch). The total trajectory length and root-mean-square of the center of pressure in the anterior-posterior and medio-lateral directions were analyzed. Light touch reduced the sway of the center of pressure in both the standing and crouching postures, particularly in the anterior-posterior direction. Furthermore, the touch effect on the sway of the center of pressure varied between the standing and crouching postures. Consistent effects were observed in the anterior-posterior direction, but differing effects were observed in the medio-lateral direction. These results indicate that somatosensory input from the fingertip reduces postural sway in both directions in a crouched posture. Variations of the center of pressure disturbances in the medio-lateral direction could originate from differences in postural strategies involving the ankle and hip joints between bipedal standing and crouching positions.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"260-268"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143494350","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}

As the mechanisms to induce a cutaneous afferent volley have been limited to electrical stimulation, it remains unknown if mechanical stimuli can modulate stretch reflex (SR) excitability. The purpose of this study was to examine the effect of adding cutaneous inputs on modulating the SR during perturbed gait termination. Thirty young adults completed walking trials when a platform unexpectedly tilted 10 degrees anteriorly or posteriorly, inducing a tibialis anterior (TA) or medial gastrocnemius (MG) short-latency reflex. The SR latency, the peak SR amplitude, and the total SR amplitude of the agonist burst, were compared between the stretched muscle and cutaneous facilitation. Statistically significant interactions were observed between the stretched muscle and cutaneous facilitation on the SR peak and SR burst. More notably, texture resulted in a consistent expression on the TA SR magnitude, without a similar effect in MG. Despite confirming the ability of cutaneous afferent facilitation on modulating spinal interneuronal circuitry, participant variability in response to texture highlights the importance of focusing on individual participant results when studying the effects of cutaneous facilitation on modulating spinal motorneuron excitability.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"311-320"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143568762","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}

However, less is known about the influence of the nature of visual feedback on torque variability. The present study aimed to investigate the effect of two different feedback natures, one from the angular position and the other from the torque produced, on the magnitude and temporal structure of torque variability during submaximal hold isometric tasks. Twenty healthy and young participants performed a knee extension isometric task, consisting in sustaining an applied resistance equivalent to 40% of their Maximal Voluntary Isometric Contraction for 30 s with visual feedback from angular position (Hangle) and with visual feedback from torque (Htorque). The magnitude of torque variability was calculated through the coefficient of variation. Sample Entropy was used to analyze the temporal structure of torque fluctuations, i.e., torque complexity. We observed no significant differences between conditions (Hangle vs Htorque) in both magnitude (p = 0.117) and the temporal structure of torque fluctuations (p = 0.940). Our results demonstrated that torque regulation seems not to be affected by the nature of the visual feedback during hold submaximal isometric tasks, suggesting a participation of sensorimotor system due to the nature of the task. Researchers should take this into account to take methodological decisions when using hold submaximal isometric tasks to investigate possible changes in motor control.","PeriodicalId":50125,"journal":{"name":"Journal of Motor Behavior","volume":" ","pages":"269-277"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143558529","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}

Recent evidence of functional interdependence between masticatory and neuromuscular systems indicates that the stomatognathic system is neurologically integrated with various body systems relevant to movement planning and execution. This study investigated the effects of unilateral molar biting and incisor biting on walking with and without visual feedback. A cohort of 31 healthy young adults aged 21 to 30 years (average age of 23.93 ± 1.89) participated in this study. Three types of errors in walking direction (angle error, position error, and curve error) were computed. Our findings indicate that, in right-handed individuals, irrespective of visual feedback, unilateral biting caused systematic deviations toward the biting side from initiation to termination of walking. The consistent deviation in walking, particularly during unilateral right biting conditions in right-handed individuals, may indicate a complex interplay between masticatory function and gait control mechanism, potentially influenced by handedness and motor lateralization within the cortex. This study establishes a foundation for future research exploring the interrelation between bite location, visual feedback, and motor control in diverse populations.
