Utilization Of An Open-Access Markerless Motion Analysis Software For A Biomechanics Movement Analysis Project., Tamra L. Llewellyn, Michael J. Nolan

Educational Practices in Kinesiology

The movement analysis project (MAP) is a common assignment in many undergraduate biomechanics courses. The purpose of this article is to introduce kinesiology educators to an open-source, AI-enabled, markerless software for motion capture, OpenCap, which can be used in MAP and research. This tool is currently being used in an in-person, upper-level, undergraduate biomechanics course where students are required to have taken Anatomy & Physiology. There is very little time, money, or expertise needed to implement this resource. Using 2 iPads on tripods and the OpenCap app and web-based interface, movements can be quickly converted to skeleton visualization and joint …

Exercise-Induced Gene Expression Profiles In Adults With Obesity: A Systematic Review Of Molecular Adaptation, Brandon Galvan, Luis Alberto Flores, Flor Isela Torres-Rojo, Natanael Cervantes-Hernández, Cinthia Verónica Villegas-Balderrama, Liliana Aracely Enríquez-Del-Castillo

Baltic Journal of Health and Physical Activity

Background: Obesity is a multifactorial and chronic condition characterized by excess adiposity and systemic low-grade inflammation. Exercise exerts metabolic and anti-inflammatory effects partly mediated through gene expression modulation in skeletal muscle and adipose tissue. However, heterogeneous responses among obese individuals suggest that genetic and epigenetic mechanisms shape exercise adaptation. Objective: This systematic review aimed to identify the genes and molecular pathways modulated by physical exercise in adults with obesity, and to classify them according to their biological functions across different exercise modalities. Methods: Following PRISMA guidelines, randomized controlled trials were searched in PubMed, SpringerLink, Science Direct, Cochrane, LILACS, Web of …
