Brendan Egan is the head of the School of Health & Human Performance at Dublin City University. Brendan’s research investigates skeletal muscle function and adaptation across the life course, with special interest in the synergy between nutrition and exercise interventions ranging from athletes to older adults

Brendan received his BSc Sport and Exercise Science from the University of Limerick in 2003, MSc Sport and Exercise Nutrition from Loughborough University in 2004, and PhD from Dublin City University in 2008, before completing two years of post-doctoral training at the Karolinska Institute.

His current projects include resisted sled sprinting, weight cutting in combat sports, and menstrual cycle and hormonal contraceptive use, as well as nutrition supplementation and performance such including exogenous ketones, beetroot juice and caffeinated chewing gum.

Outside of this Brendan has significant experience as a performance nutritionist with emphasis on field-based team sports, and endurance athletes. And we have it on very good authority that he was an exceptional athlete through his inter-county Gaelic footballer with Sligo from 2003 to 2017.
