These aspects could be provided by task performance on virtual environment. In addition, the retention interval found in these studies was short. \u0000AIM: To investigate the extent to which the learning of tasks involving a high demand for postural control is impacted in individuals with PD, and to determine the impact of the learning process on both cognition and postural control.\u0000METHOD: The Experimental Group comprised 13 participants with PD and the Control Group comprises 14 healthy elderly. Participants took part in 13 one-hour sessions, which involved four Kinect system games, with high postural and cognitive demands. The short-term retention test was performed one week after the post-test, whereas the long-term retention test was performed one month after the post-test.\u0000RESULTS: Individuals with PD learned the tasks with a high demand of postural control and demonstrated both short and long-term retention. The skill learning of the four tasks led to an improvement in cognitive functions specifically in memory. There was an improvement of reactive aspects of postural control in the elderly and with the individuals with PD, also better gait stability in the elderly.\u0000CONCLUSION:Despite the degeneration in striatum, responsible of consolidation of motor learning, individuals with PD are able to learn motor skills with a high demand for postural control, retaining them in the long term.","PeriodicalId":91007,"journal":{"name":"Brazilian journal of motor behavior","volume":"88 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81033900","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In CI, the lack of repetitiveness introduces a high level of interference within the learning context such that task performance during initial skill acquisition is frequently poorer than if tasks are practiced in a repetitive fashion. However, these learners often perform better on retention and transfer tasks than individuals who learn within a low CI environment. \u0000AIM:We provide a tutorial on several novel ways in which researchers can investigate brain activity in a CI paradigm using functional near-infrared spectroscopy: Relative neural efficiency (RNE), relative neural involvement (RNI), and laterality index (LI).\u0000METHOD:RNE integrates measures of cognitive effort and behavioral performance; in high CI learning environments, RNE should initially be poor (high cognitive effort, low behavioral performance), then improve during retention and transfer. RNI provides an index of the relationship among motivation, mental effort, and performance. Finally, LI allows for the exploration of lateralization between the two hemispheres of the cerebral cortex. \u0000RESULTS:Significant differences were found for total hemoglobin, RNE and LI for the right and left prefrontal cortex regions. The differences were accompanied by moderate-to-large effect size with random using less effort, better performance and was more oriented to goal orientation and learning processes than blocked who focused more on visuomotor attentional components and used more effort with lower behavioral performance scores.\u0000CONCLUSION:RNE, RNI, and LI provide innovative methods to better understand cognitive effort within CI paradigms.","PeriodicalId":91007,"journal":{"name":"Brazilian journal of motor behavior","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82280332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Joint torque was measured using an isokinetic dynamometer.\u0000RESULTS: The hip-abduction, -adduction, and -extension torques were negatively associated with the variables of center of pressure displacement in several conditions, both the most challenging and the least challenging ones. The ankle torque (dorsiflexion and plantar flexion) was negatively associated with postural control only in the semi-tandem condition with a rigid surface and eyes open. On the other hand, the knee torque was positively associated with the center of pressure displacement. Power measurements were more associated with postural control than peak torque.\u0000CONCLUSION: In young adults, there seems to be a greater use of the hip strategy, with greater influence of hip torque in relation to ankle torque for postural balance control. Therefore, the strengthening of hip muscles could have an impact on postural control in young adults.","PeriodicalId":91007,"journal":{"name":"Brazilian journal of motor behavior","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89379549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty reflective markers were placed on the participant's trunk and upper and lower limbs. Participants performed acceleration at maximum speed and in a straight line for 10 meters, followed by a change of direction (30º, 60º, and 90º). The whole body's COM trajectory was identified using a body model for each trial. Differences in angular error and COM speed were evaluated with a three-way analysis of variance [Group (GH vs. GC) X Cutting angle (30º vs. 60º vs. 90º) X Side (dominant and non-dominant), with repeated measures for the last two factors].\u0000RESULTS: The main results indicated that the angular error increased as the cutting angle increased. The high-level futsal athletes performed a cutting task for the dominant side with greater speed and higher angular errors than the control group. These findings provided important information for understanding the trajectory of the center of mass at different angles and velocities and the possible repercussions on body dynamics.\u0000CONCLUSION: Athletic background affected the kinematic patterns of the center of mass during sidestep cutting maneuvers; when sidestep is performed with the dominant side, high-level futsal athletes changed direction faster with more significant angular error than recreational athletes.","PeriodicalId":91007,"journal":{"name":"Brazilian journal of motor behavior","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81740895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessments were performed with the Mini Mental State Examination (MMSE) and the Falls Efficacy Scale (FES-I). Handgrip strength and upper limb pulling force were measured using dynamometers installed on a bus prototype. Execution time was determined on the single task (ST), which consisted of climbing a bus, as well as a dual task (DT) (detecting specific letters from an audio recording during the task).
