Training increases stroke volume, capillary density and mitochondrial content in muscle.
Endurance training raises mitochondria and capillaries, increases stroke volume, lowers resting heart rate. Resistance training causes muscle hypertrophy. Overtraining and inadequate recovery cause injury.
Endurance training boosts oxidative enzymes; strength training raises muscle size and neural drive. Detraining reverses gains.
Key idea: body adapts to the stress placed on it.
Training increases stroke volume, capillary density and mitochondrial content in muscle.
Exercise Adaptations is one of the 51 topics in Human Physiology. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Exercise Physiology, Bone Remodelling, Blood Pressure.
Athletes have a resting heart rate around 40 to 50 bpm.
Work through the Beginner topics in Human Physiology first, such as Homeostasis, Tissues and Organs, Skeletal System, then return to Exercise Adaptations. Advanced topics assume the Intermediate vocabulary.
The closest topics to Exercise Adaptations are Exercise Physiology, Bone Remodelling, Blood Pressure, 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 Adaptations. To practise the whole of Human Physiology, use the Human Physiology quiz.
Exercise Adaptations: Training increases stroke volume, capillary density and mitochondrial content in muscle. Exercise Physiology: Regular activity strengthens muscle, heart and bone and changes metabolism. 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 Physiology and explain the difference aloud. Finally, take the Human Physiology quiz and come back to this page for any question you miss.
