Sarah M Schwab-Farrell et al.
Individuals post-stroke commonly demonstrate alterations in motor behavior with regard to both task performance and the motor strategies used in pursuit of task goals. We evaluated whether constraining postural sway (motor strategy) during ...
Increasing Movement Amplitude in Speeded Hitting Enhances Contact Velocity Without Affecting Directional Accuracy or Movement Variability [0.03%]
增加击打速度的运动幅度可以提高接触速度而不会影响方向准确性或运动变异性

Performance of sport-related ballistic motor skills, like ball hitting in golf and baseball, requires wide movements to produce highly fast and spatially accurate movements. In this study, we assessed the effect of movement amplitude on dir...
A Holistic Focus of Attention Enhances Vertical Jump Performance Among Inexperienced Individuals [0.03%]
整体焦点注意力增强不熟练个体的垂直跳跃表现

T A Zhuravleva et al.
A holistic focus (HF) has been found to significantly improve performance over an internal focus (IF), in a similar way to an external focus (EF). There is a need to understand the effectiveness of a HF by investigating kinematic and kineti...
Examining the Equivalence Between Imagery and Execution-Does Imagery Comprise the Intended Spatial Trajectory? [0.03%]
想象与执行的等价性研究——想象是否包含预期的空间轨迹？

James W Roberts
The functional equivalence model suggests a common internal representation initiates both imagery and execution. This suggestion is supported by the mental chronometry effect, where there is a positive relation between task difficulty (as d...
Development of an Effector-Specific Stop Signal Task with Higher Complexity: A Proof-of-Concept Study [0.03%]
一种更高复杂度的效应器特定停止信号任务的发展：概念证明研究

Daghan Piskin et al.
The present study aims to develop and present a proof-of-concept for a stop signal task with effector-specificity and higher complexity. Sixteen participants performed a stop signal task developed for lower extremities using Fitlight System...
Age-Related Development of Bilateral Coordination of the Upper Limbs in Children and Adolescents [0.03%]
儿童和青少年上肢双边协调的年龄相关发展规律研究进展

Bilateral coordination of the upper limbs (UL) is important for activities of daily living and physical activities. Motor coordination improves from childhood through adolescence. However, age-coordination trajectories for bilateral UL move...
Inter-Digit Low Level Force Coordination in a Complex Isometric Pinch Tracking Task [0.03%]
复杂等轴抓捏任务中的指间低强度协同力控制

The purpose of this study was to investigate the difference in oculomotor functioning between Olympic-level contact and non-contact sports participants. In total, 67 male and female Olympic-level contact (n = 27) and non-contact (n = 40) at...
Enhanced Post-Movement Beta Rebound: Unraveling the Impact of Preplanned Sequential Actions [0.03%]
增强的运动后β回弹：揭秘预先计划的连续动作的影响
Lingli Zhang,Kaige Bao,Yu Liao
Lingli Zhang
The Post-Movement Beta Rebound (PMBR) is the increase in beta-band power after voluntary movement ends, but its specific role in cognitive processing is unclear. Current theory links PMBR with updates to internal models, mental frameworks t...
