Music style not only modulates the auditory cortex, but also motor related areas

2021

The neuroscience of music has recently attracted significant attention, but the effect of music style on the activation of auditory-motor regions has not been explored. The aim of the present study is to analyze the differences in brain activity during passive listening to non-vocal excerpts of four different music genres (classical, reggaeton, electronic and folk). A functional magnetic resonance imaging (fMRI) experiment was performed. Twenty-eight participants with no musical training were included in the study. They had to passively listen to music excerpts of the above genres during fMRI acquisition. Imaging analysis was performed at the whole-brain-level and in auditory-motor regions …

Hand‐related action words impair action anticipation in expert table tennis players : Behavioral and neural evidence

2021

Athletes extract kinematic information to anticipate action outcomes. Here, we examined the influence of linguistic information (experiment 1, 2) and its underlying neural correlates (experiment 2) on anticipatory judgment. Table tennis experts and novices remembered a hand- or leg-related verb or a spatial location while predicting the trajectory of a ball in a video occluded at the moment of the serve. Experiment 1 showed that predictions by experts were more accurate than novices, but experts’ accuracy significantly decreased when hand-related words versus spatial locations were memorized. For nonoccluded videos with ball trajectories congruent or incongruent with server actions in exper…

Task-Modulated Corticocortical Synchrony in the Cognitive-Motor Network Supporting Handwriting

2019

Abstract Both motor and cognitive aspects of behavior depend on dynamic, accurately timed neural processes in large-scale brain networks. Here, we studied synchronous interplay between cortical regions during production of cognitive-motor sequences in humans. Specifically, variants of handwriting that differed in motor variability, linguistic content, and memorization of movement cues were contrasted to unveil functional sensitivity of corticocortical connections. Data-driven magnetoencephalography mapping (n = 10) uncovered modulation of mostly left-hemispheric corticocortical interactions, as quantified by relative changes in phase synchronization. At low frequencies (~2–13 Hz), enhanced …

Effect of childhood developmental coordination disorder on adulthood physical activity; Arvo Ylppö longitudinal study

2022

Publisher Copyright: © 2022 The Authors. Scandinavian Journal of Medicine & Science In Sports published by John Wiley & Sons Ltd. Individuals at risk of Developmental Coordination Disorder (DCD) have low levels of physical activity in childhood due to impaired motor competence; however, physical activity levels in adulthood have not been established. This study sought to determine the impact of DCD risk on physical activity levels in adults using accelerometry measurement. Participants (n = 656) from the Arvo Ylppö Longitudinal Study cohort had their motor competence assessed at the age of five years, and their physical activity quantified via device assessment at the age of 25 years. Betwe…

Changes in sprint performance and sagittal plane kinematics after heavy resisted sprint training in professional soccer players

2019

Background Sprint performance is an essential skill to target within soccer, which can be likely achieved with a variety of methods, including different on-field training options. One such method could be heavy resisted sprint training. However, the effects of such overload on sprint performance and the related kinetic changes are unknown in a professional setting. Another unknown factor is whether violating kinematic specificity via heavy resistance will lead to changes in unloaded sprinting kinematics. We investigated whether heavy resisted sled training (HS) affects sprint performance, kinetics, sagittal plane kinematics, and spatiotemporal parameters in professional male soccer players.…

Reduced Peak Bone Mass in Young Adults with Low Motor Competence

2023

Although suboptimal bone health has been reported in children and adolescents with low motor competence (LMC), it is not known whether such deficits are present at the time of peak bone mass. We examined the impact of LMC on bone mineral density (BMD) in 1043 participants (484 females) from the Raine Cohort Study. Participants had motor competence assessed using the McCarron Assessment of Neuromuscular Development at 10, 14, and 17 years, and a whole body dual-energy X-ray absorptiometry scan at 20 years. Bone loading from physical activity was estimated from the International Physical Activity Questionnaire at the age of 17. The association between LMC and BMD was determined using general …

Which direction should I go? A quest for understanding the effect of TMS stimulus orientation on evoked responses

2023

The orientation of the electric field (E-field) induced by transcranial magnetic stimulation (TMS) plays a significant role in determining the magnitude of motor evoked potentials (MEP) and TMS-evoked potentials (TEP). However, fundamental mechanisms explaining the interaction of the induced E-field and the underlying neuronal populations are still largely unknown. We recently entered a quest to understand and describe neurophysiological and physical factors affecting the effect of the E-field orientation on the MEP and TEP. We developed a dual-coil TMS transducer capable of fast and accurate electronic control of the induced E-field orientation. With this transducer, we could scan the effe…

Association between developmental coordination disorder or low motor competence, and risk of impaired bone health across the lifespan: protocol for a…

2020

OBJECTIVE: This systematic review will assess the association between developmental coordination disorder and low motor competence, and impairments in bone health across the lifespan. INTRODUCTION: Individuals with developmental coordination disorder tend to have a pattern of physical activity associated with bone health impairments. Preliminary studies have found impairments in bone health measures, including fractures, throughout the lifespan with potential public health ramifications. As studies in this area are of small samples across wide age ranges no comprehensive picture of bone health in this group has been formed, hindering action. A systematic review is needed to determine the po…

Kuikka, Henna 2015. Alakoulun opettajat motoriikan arvioijina. Kasvatustieteen pro gradu –tutkielma. Jyväskylän yliopisto. Opettajankoulutuslaitos. Tämän tutkimuksen tarkoituksena oli selvittää, löytyvätkö opettajan arvioimana ne oppilaat, joilla on kehityksellisiä koordinaatiohäiriöitä eli motorisen oppimisen vaikeuksia ja kuinka luotettava Motoriikan havainnointilomake (MOQ-T) on tunnistettaessa niitä lapsia, joilla haasteita opettajan mukaan on havaittavissa. Tutkimus toteutettiin yhteistyössä Mukaan – liikun, opin, osallistun –tutkimushankkeen kanssa. Mukaan- liikun, opin, osallistun – hanke (2012 – 2014) toteutetaan yhteistyössä Suomen CP-liiton, Niilo Mäki Instituutin, Jyväskylän ylio…
