Exercise physiology is the study of how the body responds to physical exercise in the short term and adapts to it over time. These lessons answer how endurance training changes running, helping readers understand the body's responses and adaptations that shape running performance. The path follows themes of training, energy use, cooling, and muscle function.

Exercise-induced dehydration, which develops during exercise, reduces aerobic endurance performance and increases body temperature, heart rate, perceived exertion, and possibly reliance on carbohydrate as a fuel source. In exercise physiology, humans cool themselves during exercise through specialized thermoregulation based on sweat evaporation. One gram of sweat can remove 2,598 J of heat energy. Active skeletal muscle is only 22 to 26% efficient: during continuous activity, about 24 W of mechanical energy comes with about 76 W of heat.
Aerobic exercise guidelines recommend 150 minutes of moderate-intensity activity, 75 minutes of vigorous activity, or an equivalent combination each week. They also recommend muscle-strengthening activities involving all major muscle groups on two or more days a week.
