Early Horizontal Deceleration Ability Across Multiple Steps and Approach Speeds in Multidirectional Team Sport Athletes

European Journal of Sport Science, Volume 26, Issue 8, August 2026.
ABSTRACT Horizontal deceleration ability (HDA) is a critical component of multidirectional team sport performance. This study aimed to identify the interaction between external kinetic and kinematic determinants of HDA across multiple deceleration steps and approach speeds. Nineteen multidirectional team sport athletes completed five maximal horizontal

Time‐resolved PET imaging using a joint dynamic reconstruction and motion estimation framework (DREME‐PET)

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Positron emission tomography (PET) plays a critical role in image‐guided radiotherapy by enabling accurate tumor localization and contouring. To account for respiration‐induced anatomical motion, time‐resolved PET imaging is highly desirable, as it captures dynamic anatomical variations to facilitate both disease diagnosis and ...

Comparison of Marker- and Markerless-Derived Lower Body Three-Dimensional Gait Kinematics in Typically Developing Children

Sensors
Background: Marker-based motion capture is the current gold standard for three-dimensional (3D) gait analysis. This is a highly technical analysis that is time-consuming, and marker application can trigger anxiety in children.
