A neurophysiological approach to optimize resilience and performance for athletes, teams, coaches and organizations based on the framework developed by Stephen W. Porges's Polyvagal Theory. Beneath conscious awareness, the nervous system is constantly scanning what's safe and unsafe in our internal, external and relational environments. Based on whether we feel safe, in danger or overwhelmed by threat, we reflexively, adaptively shift bodily state to prepare for the situation. Because cues of risk, uncertainty and evaluation are coming at us from all directions on our competitive fields of play, it's easy for our body's to shift into a state of defense. The problem is that a body under threat isn't capable of optimal performance no matter what we think! In this book, you will learn exactly how to manage your bodily reactions to your advantage, and enter The Play Zone on demand - that relaxed, confident and fully engaged zone for peak performance!
