In this episode of Iron Culture, hosts Eric Helms and Eric Trexler engage in a lively discussion with Dr. James Steele about the evolving landscape of sports science, particularly focusing on the critiques of periodization and the importance of scientific theory in exercise research. They explore the philosophical underpinnings of scientific inquiry, the challenges of conducting robust research, and the implications of recent studies on training effects. The conversation emphasizes the need for a more theory-driven approach in exercise science to enhance the validity and applicability of research findings. In this conversation, James Steele and Eric Helms discuss the intricacies of designing meaningful studies in hypertrophy research, emphasizing the importance of collaboration, causal inference, and the need for high-powered studies. They explore the challenges of resistance training research, the significance of theory corroboration, and the future directions for the field. The discussion highlights the necessity of passion and purpose in research, advocating for a focus on practical applications and the importance of understanding the underlying mechanisms of training effects.
