Sam Moore’s path into sport science is defined by taking risks and chasing meaningful questions. After a devastating knee injury as a collegiate athlete, Moore not only returned to compete, but she also discovered her calling in strength and conditioning.

Moore describes sport science as problem-solving and drawing evidence across disciplines to drive innovation. She discusses her research on female athlete availability in elite settings, including nuances like body composition, recovery, and high speed exposure in training. Moore advises young professionals to remain open-minded, pitch their ideal position if it does not exist, and go “all in”— knowing one decision does not define forever.
