  • Involvement of global coordinative structure in achieving the local pendulum swinging task

    Yusuke Yagai, Akito Miura, Hiroyuki Mishima, Nobuhiro Furuyama

    PLOS ONE   17 ( 2 ) e0262525  2022.02  [Refereed]

     View Summary

    In the literature on inter-limb coordination, the coordination among ‘‘focal’’ body parts (i.e., the two limbs) directly engaged in a pendulum swinging task has been studied by immobilizing other body parts to reduce “noise,” while putting aside questions of how one maintains posture while performing the task. However, in practical performance of musical instruments, for example, performers must coordinate different body parts in sync with the music while maintaining the whole body’s balance. This study demonstrates the effectiveness and necessity of understanding inter-limb coordination in whole-body coordination. Participants were asked to move two pendulums either in sync or alternatively with metronome beeps under two conditions: immobile (fixed forearms) and mobile (forearms not fixed). The explorative analyses focused on whether and how coordinative structures emerged and whether the degree of task achievement differed according to the phase mode, frequency, and mobility conditions. The motion similarity and phase difference between different parts and the pendulums showed that task-specific coordinative structures emerged in both immobile and mobile conditions. In the in-phase mobile condition, the emergent coordinative structure may have improved task achievement, shown by the phase difference between the left and right pendulums. These findings suggest that the global coordinative structure is involved in achieving the local pendulum swinging task.

  • Motor control of practice and actual strokes by professional and amateur golfers differ but feature a distance-dependent control strategy

    Yumiko Hasegawa, Keisuke Fujii, Akito Miura, Keiko Yokoyama, Yuji Yamamoto

    European Journal of Sport Science   19 ( 9 ) 1204 - 1213  2019.10  [Refereed]  [International journal]

     View Summary

    We explored how practice and actual putting strokes differed between professionals and high-level golf amateurs, and how practice strokes reflected subtle differences in putting distances. We analysed swing amplitude, impact velocity, and acceleration profile of the club-head. The acceleration profiles showed that the motor control pattern of the practice stroke differed from that of the actual stroke. To clarify the effects of different putting distances on the practice stroke and to analyse how much the actual stroke could be explained by the practice stroke, we conducted individual regression analyses. The practice strokes of all participants could be divided into three strategies and five types by the coefficient of determination and the slope. This implies that the purpose of the practice stroke varied among golfers. Most golfers used the individual velocity criteria in their practice strokes, which resulted in different putting distances based on their criteria. Unexpectedly, we found no significant difference in skill level between professionals and high-level amateurs. The results of this study imply that the practice stroke does not duplicate the actual stroke, even for professional golfers with excellent skills. However, most high-level golfers adopted distance-dependent control strategies for slightly different putting distances.

  • Modulation of individual auditory-motor coordination dynamics through interpersonal visual coupling

    Kohei Miyata, Manuel Varlet, Akito Miura, Kazutoshi Kudo, Peter E. Keller

    Scientific Reports   7 ( 1 ) 16220  2017.12  [Refereed]

     View Summary

    The current study investigated whether visual coupling between two people producing dance-related movements (requiring whole-body auditory-motor coordination) results in interpersonal entrainment and modulates individual auditory-motor coordination dynamics. Paired participants performed two kinds of coordination tasks - either knee flexion or extension repeatedly with metronome beats (Flexion-on-the-beat and Extension-on-the-beat conditions) while standing face-to-face or back-to-back to manipulate visual interaction. The results indicated that the relative phases between paired participants' movements were closer to 0° and less variable when participants could see each other. In addition, visibility of the partner reduced individual differences in the dynamics of auditory-motor coordination by modulating coordination variability and the frequency of phase transitions from Extension-on-the-beat to Flexion-on-the-beat. Together, these results indicate that visual coupling takes place when paired participants can see each other and leads to interpersonal entrainment during rhythmic auditory-motor coordination, which compensates for individual differences via behavioural assimilation and thus enables individuals to achieve unified and cohesive performances.

  • Resolution of low-velocity control in golf putting differentiates professionals from amateurs

    Yumiko Hasegawa, Keisuke Fujii, Akito Miura, Yuji Yamamoto

    Journal of Sports Sciences   35 ( 13 ) 1239 - 1246  2017  [Refereed]

     View Summary

    It is difficult for humans to apply small amounts of force precisely during motor control. However, experts who have undergone extended training are thought to be able to control low-velocity movement with precision. We investigated the resolution of motor control in golf putting. A total of 10 professional and 10 high-level amateur golfers participated. Putting distances were 0.6-3.3 m, in increments of 0.3 m. We measured the impact velocity and the club-face angle at impact, and the acceleration profile of the downswing. The professionals showed significantly smaller coefficients of variation with respect to impact velocity and smaller root mean square errors in relation to acceleration profiles than did the amateurs. To examine the resolution of motor control for impact velocity, we investigated intra-participant differences in the impact velocity of the club head at two adjacent distances. We found that professionals had higher velocity precision when putting small distance intervals than did amateurs. That is, professionals had higher resolution of low-velocity control than did high-level amateurs. Our results suggest that outstanding performance at a task involves the ability to recognise small distinctions and to produce appropriate movements.

     View Summary

    This study investigated whole-body sensorimotor synchronization (SMS) in street dancers and non-dancers. Two kinds of knee bending movement in a standing position to a metronome beat were explored in terms of stability under different movement frequencies: down-movement condition (knee flexion on the beat) and up-movement condition (knee extension on the beat). Analyses of phase relation between movement and beat revealed several distinct differences between the down- and up-movement conditions, and between dancers and non-dancers. In both groups under the up-movement condition, deviation from intended phase relation at higher beat rates, and enhanced fluctuations were observed. The deviation from intended phase relation under up-movement condition, and movement fluctuations were greater in non-dancers than in dancers. Moreover, subjective difficulty rating revealed that both groups felt that the up-movement condition was more difficult at higher beat rates. These findings suggest that down and up movements are two distinguishable coordination modes in whole-body coordination, and that street dancers have superior whole-body SMS ability. © 2010 Elsevier B.V.

  • Neurophysiological and Dynamical Control Principles Underlying Variable and Stereotyped Movement Patterns During Motor Skill Acquisition

    Kazutoshi Kudo, Makoto Miyazaki, Hirofumi Sekiguchi, Hiroshi Kadota, Shinya Fujii, Akito Miura, Michiko Yoshie, Hiroki Nakata

    Journal of Advanced Computational Intelligence and Intelligent Informatics   15 ( 8 ) 942 - 953  2011.10  [Refereed]

     View Summary

    While novices who are unfamiliar to a new motor skill typically show variable and unstable movements, highly skilled experts show a stable and accurate performance. These distinct differences in motor control between experts and novices have led researchers to hypothesize that neuromotor noise is reduced in the process of motor skill acquisition. On the other hand, it should be noted that novices’ movements have other characteristics; they are habituated and stereotyped. In this review, we discuss the principles governing spatiotemporal organization of movements in novices and experts while solving specific motor problems under varied conditions, by introducing experimental and theoretical studies that use neurophysiological techniques such as electromyography, functional magnetic resonance imaging, and transcranial magnetic stimulation, and mathematical models such as stochastic and dynamical models. On the basis of the findings from a variety of perceptual-motor skills (e.g., ballthrowing, badminton smash, long-distance running, piano and drum performance, street dance, a popular hand game of rock-paper-scissors, and temporal order judgement task), we argue that the novices’ characteristic movement patterns were organized under specific constraints and typical strategy, without which the variability would increase even more, while experts’ movements were organized with functional and compensatory variability that can drive out erroneous noise variability. We also showed that in a particular type of interlimb coordination, skilled and unskilled movement patterns could be seamlessly described as the time evolution of nonlinear and self-organized dynamical systems, suggesting that the dynamical systems approach is a major candidate for understanding the principle underlying organization of experts’ and novices’ movements.

  • Characteristics of the athletes' brain: Evidence from neurophysiology and neuroimaging

    Hiroki Nakata, Michiko Yoshie, Akito Miura, Kazutoshi Kudo

    Brain Research Reviews   62 ( 2 ) 197 - 211  2010.03  [Refereed]

     View Summary

    We review research on athletes' brains based on data obtained using non-invasive neurophysiological and neuroimaging methods
    these data pertain to cognitive processing of visual, auditory, and somatosensory (tactile) stimulation as well as to motor processing, including preparation, execution, and imagery. It has been generally accepted that athletes are faster, stronger, able to jump higher, more accurate, more efficient, more consistent, and more automatic in their sports performances than non-athletes. These claims have been substantiated by neuroscientific evidence of the mechanisms underlying the plastic adaptive changes in the neuronal circuits of the brains of athletes. Reinforced neural networks and plastic changes are induced by the acquisition and execution of compound motor skills during extensive daily physical training that requires quick stimulus discrimination, decision making, and specific attention. In addition, it is likely that the manner of neuronal modulation differs among sports. We also discuss several problems that should be addressed in future studies. © 2009 Elsevier B.V.

     View Summary

    これまでの身体運動科学では、目標となる動作からの誤差を定量化することで、運動学習の過程を記述してきた。しかしながらこの方法論では、目標となる動作が設定されない状況での運動学習過程を科学することができない。たとえば、ストリートダンスでは踊りのオリジナリティが求められる。ストリートダンスが上達するということは、踊りが人と違うものに変化していくことを意味する。このようなダンスの上達過程は、踊りの「正解」を設定できないため、科学的に評価することができなかった。この問題を解決するため、本研究では新しく運動が創造されていく過程を記述する方法論を開発することを目的とした。具体的には、機械学習の手法を応用し、多自由度の身体から生み出される多様な運動を低次元の変数で表現する。課題動作として、まずは私がこれまでに運動のデータを蓄積してきたストリートダンスを用いることとした。
    2021年度には、コロナ渦により動作計測実験を十分に行えなかったため、これまで計測してきた手持ちのデータを用いて、いくつかの事項を検討した。たとえば、機械学習により多自由度の運動を低次元の変数で表現する際に、入力するデータの時間解像度はどの程度にするかなどである。入力する運動データが、どれくらいのサンプリングレートであるべきか、またデータの時間幅がどの程度が適切かについて検討したが、これについてはまだ結論がでていない。ストリートダンスへの応用を考えるならば、ストリートダンスで鍵となる運動の情報を損なわないことが重要である。この点については、今後、ストリートダンスの熟練者の運動データを取得し、そのデータを用いて検討していくことで明らかになると考えられる。

     View Summary

    The purpose of this study was to clarify what makes skilled drummers different from unskilled drummers, especially the relationship between local beat movements and global whole-body movements. We analyzed the performance of skilled and novice drummers on the task of playing 1/8 note beats on an electronic drum, as well as the center of pressure (CoP) data, which is representative of whole-body motion during the performance of the task. This feature is more pronounced immediately after kicking the bass drum pedal. We also analyzed movement data of pendulum wiggling at the wrist and the whole-body, which are the basis of such local and global movements including drum-set playing. The results suggest that the global coordination structure is involved in the accomplishment of the local pendulum task.

     View Summary

    This study investigated the neural mechanisms of precisely synchronized movements in terms of the involvement of the mirror neuron system, focusing on the φ2 enhancement (12-13 Hz) and the φ1 attenuation (10-12 Hz) of EEGs when a pair of participants sitting face-to-face repeatedly flexed and extended their right wrist with the explicit intention of synchronizing their movements. Results of experiments using athletes from double sculls (rowing) and cheerleading suggested that the leader in the task may inhibit their mirror neuron system in order to eliminate any influence of the follower's movements whereas the follower may activate their system, resulting in high entrainment. It was also suggested that for participants in some sports, including cheerleading, the lower interoceptive awareness might be advantageous for skill acquisition. This study further corroborated the significance of φ1 and φ2 for the evaluation of the mirror neuron system.

    実験では、二者が複数の距離(つま先間の距離が20、40、60、80、100cm)で向かいあって立つ(対面条件)、背中を向けて立つ(背面条件)という2つの条件を設定した。姿勢動揺は床反力計および動作解析装置を用いて計測した。対面条件においては、腕の組み方が二者間の相互作用に影響する可能性が示唆された。これは動作計測上の制約から、手を前か後ろで組んで静的立位を保持する必要があったために、両条件を比較したことから見つけたことである。また二者の運動変数に対して、非線形時系列解析を行った。二者の各部位(頭部、股関節、膝関節、足関節など)同士に対して解析を行い、部位間で比較した。その結果、(1)自分の顔が相手の顔に近づいた場合に素早く距離を保っていること、(2)その際の素早い頭部の動きが、身体各部の協調によって行われていること、(3)その協調の仕方が距離に依存して変化すること、の3点が明らかになった。

    It has been reported that interpersonal motor coordination interacts with mental activity. For instance, synchrony with other people enhances affiliation and helping behavior for him/her. In this study, in order to progress understanding of neural mechanism for this process, I developed new method to quantify coupling strength between visually connected two people during rhythmic interpersonal motor coordination. This method enables to evaluate interaction between the extent of motor synchrony and that of psychological change, which leads to clarification of neural mechanism underlying behavioral data.

  • 外反母趾とバレエテクニックの関係

    2019  

     View Summary

    本課題研究は学術系クラウドファンディングサイト「academist(アカデミスト)」課題名「科学の知見に基づく指導法をバレエの世界に届けたい」によるプロジェクトの一部を担うものである。バレエダンサーは外反母趾の罹患率が高く、外反母趾は職業病であるという認識が一般的である。指導の現場では、外反母趾は間違ったバレエのテクニックから生じるとされているが、それらの運動学的な関係は十分に検証されていない。そこで本研究では、バレエダンサーが様々なバレエテクニックを行う際の運動を計測し、外反母趾の程度との関連を調査することを目的とした。これまでに予備実験を行い本実験における実験条件を詳細に検討した。
