Sex Differences in Physical Fitness in Recreational CrossFit® Participants

Manoel J. Rios, David B. Pyne, Ricardo J. Fernandes, João Ribeiro et autres

CrossFit® requires the integration of strength, power, and cardiorespiratory fitness, although sex-related differences across these physical fitness components remain poorly characterized in recreational participants. This study compared anthropometric characteristics, body composition, neuromuscular performance, maximal strength, and cardiorespiratory fitness between male and female …

Artificial Intelligence in Swimming Biomechanics and Fluid Dynamics: A Structured Narrative Review Towards Mechanistically Interpretable Models

Ricardo J. Fernandes, Márcio Fagundes Goethel

Artificial intelligence is increasingly used in sport performance analysis, but its contribution to swimming biomechanics and fluid dynamics remains fragmented across wearable sensing, computer vision, predictive analytics and computational modelling. This structured narrative review synthesises current applications and evaluates how artificial intelligence …

Effects of Boat Class and Size on Intracycle Velocity Variation During 2000 m Competitive Rowing: A GPS- and Accelerometry-Based Assessment

Joana Leão, Ricardo Cardoso, Aléxia Fernandes, Leandro Machado et autres

Rowing performance depends on boat velocity and technical efficiency, varying across boat classes. We quantified intracycle velocity variation (IVV) during 2000 m competitions using a GPS- and accelerometry-based monitoring and examined its relationship with biomechanical variables. Forty-nine races were recorded during three …
