In this of Fast Physiology on the Critical Oxygen Podcast, Dave Schell and I discuss the stress response of our bodies to exercise and the release of stress hormones like catecholamines. We explain that exercise is a massive stress on the body, causing physiological changes such as increased heart rate and the release of stress hormones. The release of stress hormones helps the body adapt and try to establish a steady state during exercise. TAKEAWAYS 1) Exercise is a massive stress on the body, causing physiological changes and the release of stress hormones. 2) The release of stress hormones helps the body adapt and establish a steady state during exercise. 3) Chronic stress can blunt the body's ability to adapt and negatively impact overall health. 4) Managing stress, both in training and in life, is crucial for optimal adaptation and performance.
