HRV Trace - Training For Resilience Under Stress NOTE: HRV Trace has been tested with the following heart rate monitors: Zephyr HxM Smart, Polar H7, FirstBeat. Other monitors may not function with the app. You will need to purchase a heart rate monitor separately. HRV Trace opens a window into your stress-response system by showing you the shape of your heartbeat pattern, your HRV Trace. As your heart traces a path, beat-by-beat, across the screen, you receive instantaneous information that enables you to respond more effectively to stress. Stress comes from our environment. To respond to stress we must activate our sympathetic nervous system. This causes strain on our body. Stress --> Sympathetic Activation --> Strain We cannot escape from stress because it is a part of life. We can learn to regulate our level of sympathetic activation so that we respond instead of react. And we can reduce the strain that comes dealing with stress. By managing our stress we can improve our health, our performance at work, sports, and school, and our relationships. HRV Trace will help you learn the following skills: Recover - how to shift quickly to a state in which you recover from strain and recharge Ready - maintain a level of activation that adapts to a dynamic situation Reset - reduce excessive activation in seconds Recondition - reduce excessive reactions that have been conditioned to stressful situations Together these skills increase your effectiveness under pressure and enable you to sustain a high level of intensity. Each of the skills creates a certain type of pattern in the heart trace. These patterns vary from individual to individual. The process for using HRV Trace is: 1) Use HRV Trace to identify your heart trace signature for each of the skills: Recovery, Ready, Reset and Recondition. 2) Apply these skills as instructed to increase your recovery rate from stress, and increase your ability to handle stress with less strain. 3) Use HRV Trace to check your progress. HRV Trace applies techniques from chaos theory used to analyze complex systems. That makes it a powerful tool for augmenting stress-reduction, mindfulness, and resiliency training programs. It is meant to be used with the guidance of a professional who is familiar with stress and heart-rate changes under stress, preferably one trained in the use of the app by Ibernetics, LLC. HRV Trace has been integrated into the training program for law enforcement officers offered by the International Performance Resilience and Efficiency Program, www.proresilience.org. Some people may already be familiar with stress-reduction concepts and so may be able to benefit without professional guidance. If you wish to use HRV Trace on your own then please see our terms of use. HRV Trace developed by Ibernetics, LLC iOS programming by Owen L Brown at www.back-40.com
