'''Anaerobic metabolism''' and '''aerobic metabolism''' (anaerobic respiration and aerobic respiration) are the two methods of generating energy in the human body, including converting food sources into energy for [[exercise]], mental activity and physical activity.<ref name="ch10b">{{Cite book | title = Nutrition: Science and Everyday Application | first =Alice | last = Callahan | first2 = Heather | last2 = Leonard | first3 = Tamberly | last3 = Powell | url = https://openoregon.pressbooks.pub/nutritionscience/chapter/10b-fuel-sources-exercise/ |chapter=10b -Fuel sources for exercise | date = Oct 14, 2020|isbn=978-1-63635-003-5 }}</ref> ==Aerobic respiration == [[File:Cellular-respiration.jpg|thumb|center|Cellular respiration during muscle [[metabolism]].<br> Source: {{Cite book | last = Betts | first = JG | author-link = | last2 = Young | first2 = KA | author-link2 = | last3 = Wise | first3 = JA | last4 = Johnson | first4 = E | last5 = Poe | first5 = B | last6 = Kruse | first6 = DH | last7 = Korol | first7 = O | last8 = Johnson | first8 = JE | last9 = Womble | first9 = M | last10 = DeSaix | first10 = P | date = Apr 25, 2013 | website = OpenStax |location=Houston, Texas|language=en |archive-url=|archive-date=|url-status= |chapter-url=https://openstax.org/books/anatomy-and-physiology/pages/10-3-muscle-fiber-contraction-and-relaxation |chapter=10.3 Muscle Fiber Contraction and Relaxation | title = Anatomy and Physiology | url=https://openstax.org/books/anatomy-and-physiology/pages/1-introduction }}<ref name="10-3-muscle-fibre"/>]] Aerobic respiration is also known as cellular respiration.<ref name="10-3-muscle-fibre">{{Cite book | last = Betts | first = JG | author-link = | last2 = Young | first2 = KA | author-link2 = | last3 = Wise | first3 = JA | last4 = Johnson | first4 = E | last5 = Poe | first5 = B | last6 = Kruse | first6 = DH | last7 = Korol | first7 = O | last8 = Johnson | first8 = JE | last9 = Womble | first9 = M | last10 = DeSaix | first10 = P | date = Apr 25, 2013 | website = OpenStax |location=Houston, Texas|language=en |archive-url=|archive-date=|url-status= |chapter-url=https://openstax.org/books/anatomy-and-physiology/pages/10-3-muscle-fiber-contraction-and-relaxation |chapter=10.3 Muscle Fiber Contraction and Relaxation | title = Anatomy and Physiology | url=https://openstax.org/books/anatomy-and-physiology/pages/1-introduction | access-date = 2022-01-28 }}</ref> {{See also|Cellular respiration}} ==Anaerobic exercise== '''Anaerobic exercise''' is high-intensity exercise that is meant to be very short (10 to 15 seconds) and fast/powerful, and usually can't be sustained for long. Typically the exercise is then repeated after a short rest.<ref name="difference"/> The word "anaerobic" means without oxygen, instead of using oxygen to keep [[muscle]]s going, the energy already stored in the muscles is used, known as [[glycogen]].<ref name="difference"/> [[File:Anaerobic-aerobic-exercise-by-time.png|center|500px|thumb|Exercise starts with anaerobic metabolism, which relies on [[adenosine triphosphate|ATP]].<ref name="ch10b"/>]] [[File:Anaerobic-aerobic-exercise-fuel-differences.jpg|center|thumb|Aerobic exercise is less intense and begins after anaerobic metabolism ends.<ref name="ch10b"/>]] Examples include: *Resistance training, like using gym machines with weights *Very short sprints *Weight lifting<ref name="difference"/> {{clear|both}} ==Aerobic exercise == '''Aerobic exercise''' is "[[cardiovascular]] conditioning ("cardio") that strengthens both your [[heart]] and lungs, using continuous movements.<ref name="difference"/> The word '''aerobic''' means "with oxygen," aerobic exercise is fueled by the oxygen from breathing, which means it can be carried out for an extended period of time.<ref name="difference"/><br> Examples include: *Running or jogging *Walking at a brisk pace *Swimming *Rowing *Cycling *Step aerobics or aqua aerobics *Using cardio machines like an elliptical or stair climber<ref name="difference">{{Cite web | url = https://www.webmd.com/fitness-exercise/difference-between-aerobic-and-anaerobic-exercise | title = Difference between aerobic and anaerobic exercise | website = WebMD | date = 2021 | access-date = 2022-01-28}}</ref> ==Energy sources and processes== [[File:Aerobic-anaerobic-metabolism.jpg|center|thumb|Normal energy metabolism processes in people without [[ME/CFS]] rely on multiple processes.<ref name="ch10b"/>]] ==See also == *[[Cellular respiration]] *[[Exercise]] *[[Post-exertional malaise]] ==Learn more == *[https://openoregon.pressbooks.pub/nutritionscience/chapter/10b-fuel-sources-exercise/ Chapter 10b -Fuel sources for exercise] - OpenOregon Press ==References == {{Reflist}} [[Category:Energy system]] [[Category:Biochemistry and cell biology]]
