Shrnutí	Excess post-exercise oxygen consumption (EPOC), commonly called the 'afterburn effect', is the elevated rate of oxygen uptake and metabolic activity that persists after exercise ends. First systematically studied by Brehm and Gutin (1986), EPOC reflects the energy cost of restoring homeostasis after physical exertion. During recovery, the body must replenish phosphate stores, clear lactate, restore oxygen debt to muscles, increase body temperature, and return cardiovascular and respiratory function to baseline. This lingering metabolic elevation results in continued calorie burning long after exercise stops, a phenomenon of significant interest in sports science and fitness.	Heart rate recovery (HRR) is the decline in heart rate during the first minutes following maximal or submaximal exercise, reflecting the reactivation of parasympathetic (vagal) tone. Introduced as a clinical predictor by Cole and colleagues (1999), HRR serves as a non-invasive biomarker of cardiac autonomic function and overall cardiovascular health. A rapid decline in heart rate after exertion indicates efficient parasympathetic reactivation and healthy autonomic nervous system balance. Conversely, blunted HRR (slow heart rate recovery) is associated with increased mortality risk, autonomic dysfunction, and poor exercise tolerance.	The respiratory exchange ratio (RER), also called the respiratory quotient (RQ), is the ratio of carbon dioxide produced to oxygen consumed during metabolism. Introduced by J. B. Weir (1949), RER is a non-invasive indirect measure of substrate utilization—indicating whether the body is primarily oxidizing carbohydrate, fat, or protein. RER values range from approximately 0.7 (pure fat oxidation) to 1.0 (pure carbohydrate oxidation) and higher under anaerobic conditions. By measuring exhaled and inhaled gases during exercise, RER reveals which fuel source predominates at different intensities, providing insights into metabolic flexibility and exercise physiology.
