Biofeedback training can enhance esports players’ shooting performance in an aiming task
High-skilled esports players have unique cortical activity and gaze control, both of which are closely linked to their performance. To enhance key aspects of esports performance—shot time and accuracy—the current study implemented two training methods: a cortical activity-based method (Experiment 1) and a gaze control-based method (Experiment 2). In Experiment 1, a three-channel electroencephalogram headset was used to provide participants with r…
Synergistic muscle coordination of the Paralympic wheelchair tennis champion
These results indicate that elite serve performance is supported not only by muscular strength but also on specialized neuromuscular coordination strategies optimizing trunk rotation and energy transfer. They may be consistent with broader ideas of use-dependent and impairment-related adaptation described in the "Paralympic brain" framework. This study provides new insights into adapted motor strategies in Paralympic sport, underscoring the role …
Coordinate System Transformation Method for Comparing Different Types of Data in Different Dataset Using Singular Value Decomposition
In the current era of AI technology, where systems increasingly rely on big data to process vast amounts of societal information, efficient methods for integrating and utilizing diverse datasets are essential. This article presents a novel approach for transforming the feature space of different datasets through singular value decomposition (SVD) to extract common and hidden features as using the prior domain knowledge. Specifically, we apply thi…
Biomechanical strategies to maximize gait attractiveness among women
Physical attractiveness is a key factor in social communication, and through this communication process, we attractively brand and express ourselves. Thus, this study investigated the biomechanical strategies used by women to express gait attractiveness. Our aim was to extend the current literature by examining this aspect of dynamic motion from the perspective of expressed , rather than perceived attractiveness. In this regard, we obtained motio…
Effects of Occasional and Habitual Wearing of High-Heeled Shoes on Static Balance in Young Women
The purpose of this study was to examine the effects of occasional and habitual wearing of high-heeled shoes on static balance in young women. Groups of habitual high-heel wearers and non-wearers ( n = 7 in both groups) were asked to stand quietly on a force platform without shoes (WS condition) or with high heels (heel area 1 cm 2 , heel height 7 cm) (HH condition). During the trials, the center-of-pressure (CoP) position in the anterior-posteri…
Influence of Release Parameters on Pitch Location in Skilled Baseball Pitching
This study explored the mechanical factors that determine accuracy of a baseball pitching. In particular, we focused on the mechanical parameters at ball release, referred to as release parameters. The aim was to understand which parameter has the most deterministic influence on pitch location by measuring the release parameters during actual pitching and developing a simulation that predicts the pitch location from given release parameters. By c…
Metaboreceptor-mediated Muscle Oxygen Saturation during Recovery Following Isometric Handgrip Exercise
The aim of the present study was to determine whether oxygen supply to non-exercised muscle during recovery following fatiguing exercise is influenced by accumulated metabolites within exercised muscle. Twelve healthy male subjects performed 2-min isometric handgrip exercise at 40% maximal voluntary contraction with their right hand and the exercise was followed by a 3-min recovery period. Muscle oxygen saturation (SmO(2)) determined by near-infr…
