February 21, 2020

Brendan Egan, PhD is Associate Professor of Sport and Exercise Physiology at the School of Health and Human Performance, Dublin City University, Ireland, and a Visiting Research Scientist at the Institute for Human and Machine Cognition, Pensacola. Brendan received his BSc Sport and Exercise Science from the University of Limerick (Ireland), MSc Sport and Exercise Nutrition from Loughborough University (UK), and PhD from Dublin City University, and completed post-doctoral training at the Karolinska Institute, Sweden. His research has investigated the molecular regulation of 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. His research group now primarily performs human trials involving both acute and chronic interventions for outcomes around performance (physical and cognitive), recovery and adaptation. Nutrients recently and presently under investigation include caffeine, creatine, omega-3 fatty acids, resveratrol, leucine, protein hydrolysates, and exogenous ketone supplements. In the healthy ageing realm, the group is exploring novel exercise training modalities in older adults including the efficacy of bodyweight-based training methods and the application of concurrent aerobic and resistance exercise training. Outside of academic research, Brendan has been an applied practitioner working in performance nutrition for over 15 years, predominantly with team sport athletes such as Gaelic games where he himself played at an elite level for over 10 years, but also recently moving into endurance sports with the Irish paratriathlon team among others.

#088 - Jim Crowell 2019 Reflections

January 3, 2020


Jim Crowell loves doing two things over all else…. Building businesses and mentoring coaches and business owners to enjoy inspiring, fulfilling, and successful careers. He attended Penn State University where he double majored in Finance and Economics. After graduation, Jim moved into the fast paced environment of a commodities trading hedge fund first in Columbus, OH and then in Austin, TX. After five years in the financial arena, Jim couldn’t ignore his heart anymore; he left finance in pursuit of fitness.

For the next four years he founded and successfully scaled multiple fitness facilities in Pittsburgh. He built his reputation around three main principles: hard work, progress, and fulfillment. Those ideas lead him to earn a Business Designation with honors from The Harvard Business School, as well as his MBA through the Kenan-Flagler Business School at The University of North Carolina (UNC) while concurrently working full time.

After his tenure in Pittsburgh, Jim was honored to join OPEX in sunny Scottsdale, AZ. His unique background helps him understand that every coach and business situation is different and needs to be treated with mindful strategy and relentless execution.
