Sex-related differences in core muscle morphology and activation in amateur CrossFit® athletes: An ultrasound imaging study. Journal of Bodywork and Movement Therapies, 44, 489-493. https://doi.org/10.1016/j.jbmt.2025.05.0731360-85921532-9283https://hdl.handle.net/11268/16443CrossFit® is a high-intensity functional training modality that integrates resistance exercises, weightlifting, and aerobic conditioning. Core musculature plays a critical role in ensuring spinal stability, force transmission, and injury prevention. Males showed greater core muscle thickness, while females exhibited a higher activation capacity in the TrAb. These findings suggest sex-specific adaptations in core musculature, which have implications for tailored training and injury prevention strategies in CrossFit® athletes.engjournal article10.1016/j.jbmt.2025.05.073embargoed accessCiencias médicasRehabilitación médicaDeporteGoal 3: Ensure healthy lives and promote well-being for all at all agesGoal 4: Quality educationGoal 5: Achieve gender equality and empower all women and girls
