Cellular Signals and Exercise Adaptation

The chapter explores the signals that contribute to cellular adaptation during exercise, such as calcium, ATP, redox, and NADH. It emphasizes the importance of these signals as reliable indicators for adaptation and challenges the belief that carbs and fat are the main signals. The chapter also discusses the origin of these signals in yeast, bacteria, and archaea, and highlights the mechanism of action and the importance of riding more for better signaling.
