== Risks and disadvantages ==
Some drawbacks of aerobic exercise include:

* Overuse injuries of the [[musculoskeletal system]] because of repetitive exercise, with young athletes (under the age of 19) particularly at risk<ref name=":3">{{Cite journal |last1=Scheer |first1=Volker |last2=Tiller |first2=Nicholas B. |last3=Doutreleau |first3=Stéphane |last4=Khodaee |first4=Morteza |last5=Knechtle |first5=Beat |last6=Pasternak |first6=Andrew |last7=Rojas-Valverde |first7=Daniel |date=2022-04-01 |title=Potential Long-Term Health Problems Associated with Ultra-Endurance Running: A Narrative Review |url=https://doi.org/10.1007/s40279-021-01561-3 |journal=Sports Medicine |language=en |volume=52 |issue=4 |pages=725–740 |doi=10.1007/s40279-021-01561-3 |issn=1179-2035 |pmc=8450723 |pmid=34542868}}</ref>
* [[Overtraining]] syndrome may lead to persistent dysfunction of a number of body systems<ref>{{Cite journal |last1=Kreher |first1=Jeffrey B. |last2=Schwartz |first2=Jennifer B. |date=2012 |title=Overtraining Syndrome |journal=Sports Health |volume=4 |issue=2 |pages=128–138 |doi=10.1177/1941738111434406 |issn=1941-7381 |pmc=3435910 |pmid=23016079}}</ref>
* High volumes of training with insufficient calorie intake puts athletes—particularly female ones—at risk for [[RED-S]]<ref name=":3" />
* Aerobic exercise may not be as efficient as other exercise methods. For example, [[High-intensity interval training]] (HIIT) has been shown to provide similar benefits in a fraction of the time spent exercising per week.<ref>{{cite journal | vauthors = Ito S | title = High-intensity interval training for health benefits and care of cardiac diseases – The key to an efficient exercise protocol | journal = World Journal of Cardiology | volume = 11 | issue = 7 | pages = 171–188 | date = July 2019 | pmid = 31565193 | pmc = 6763680 | doi = 10.4330/wjc.v11.i7.171 | doi-access = free }}</ref>

Both the health benefits and the performance benefits, or "training effect", require that the duration and the frequency of exercise both exceed a certain minimum. Most authorities suggest at least twenty minutes performed at least three times per week.<ref>'aerobic exercise', ''Food and Fitness: A Dictionary of Diet and Exercise'', Michael Kent, Oxford University Press, 1997.</ref>
