Regular activity strengthens muscle, heart and bone and changes metabolism.
Heart rate, stroke volume and breathing increase; blood is redirected to muscles. Training lowers resting heart rate, increases muscle mass and strengthens bone.
Muscle blood flow increases up to 20-fold. Sweating dissipates heat. Fatigue has central and peripheral causes.
Key idea: regular exercise improves nearly all body systems.
Regular activity strengthens muscle, heart and bone and changes metabolism.
Exercise Physiology is one of the 51 topics in Human Physiology. It is rated Beginner, so it suits learners who are starting out in biology. Related topics in this area include Exercise Adaptations, Blood Pressure, Thermoregulation.
VO2 max measures aerobic fitness.
Exercise Physiology is a Beginner topic, so no earlier topic is required. Other Beginner topics in Human Physiology that pair well with it include Homeostasis, Tissues and Organs, Skeletal System.
The closest topics to Exercise Physiology are Exercise Adaptations, Blood Pressure, Thermoregulation, Frank-Starling Law. Comparing them side by side is a good way to see how the ideas connect.
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Exercise Physiology. To practise the whole of Human Physiology, use the Human Physiology quiz.
Exercise Physiology: Regular activity strengthens muscle, heart and bone and changes metabolism. Exercise Adaptations: Training increases stroke volume, capillary density and mitochondrial content in muscle. Read both side by side and note what each one explains.
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Exercise Adaptations and explain the difference aloud. Finally, take the Human Physiology quiz and come back to this page for any question you miss.
