  • Interaction of target distance and movement type on lower limb kinematics in fencing

    Open Access•Kenta Chida, Takayuki Inami et al.•ARTICLE•Frontiers in Sports and Active…•2026

    These findings suggest that the effectiveness of attack movements in fencing depends on the interaction between target distance and movement type. Fencers should select LWOA or LWA according to tactical distance while emphasizing rear-leg flexion and extension movements during training

  • Design and evaluation of leadership development program using co-creation approaches for an athlete leadership group among elite high school rugby teams

    Open Access•Toshiaki Hirose, Yasutaka Ojio et al.•ARTICLE•Frontiers in Sports and Active…•2026•References: 7

    These findings suggest that this program was feasible and acceptable. Brief delivery initiated meaningful insights and short-term behavioral change, while the sustained cycle produced broader impact within teams. Earlier-season, longer-duration implementation may further support youth rugby talent development and the cultivation of sustainable shared leadership structures

  • Design of Multiple Spatial Context Detection Method Considering Elongated Top-Bounded Spaces Based on GPS Signal-To-Noise Ratio and Fuzzy Inference

    Open Access•Kenichi Tabata, Madoka Nakajima et al.•ARTICLE•ISPRS International Journal of…•2020

    Numerous studies have been conducted on indoor and outdoor seamless positioning and indoor–outdoor detection methods. However, the classification of real space into two types, outdoor space and indoor space, is difficult. One type of space that is difficult to classify is top-bounded space, which can be observed in commercial facilities, logistics facilities, and street-facing sidewalks. In this study, we designed a method for detecting stays in …
