At the 2024 Paris Olympics , the young challenger is 11 - year - old Chinese skateboarderZheng Haohao . She ’s just one year honest-to-goodness than the young Olympian in history : 10 - twelvemonth - old Hellenic gymnast Dimitrios Loundras , who bring home the bacon a bronze at the 1896 Summer Olympics in Athens .
The oldest jock at the Paris Games is AustralianMary Hanna , 69 , who compete in equestrian . She ’s three years shy of the oldest - ever Olympian jock , Oscar Swahn of Sweden , who clinched that record book at the 1920 Antwerp Games .
At just 11 years old, Chinese skateboarder Zheng Haohao is the youngest competitor in the 2024 Olympics.
These athletes are outliers . concord to a2021 studyby the Arc Centre of Excellence in Population Ageing Research ( CEPAR ) , two - thirds of athletes at the Tokyo Olympics , hold in 2021 , were in their 20s . Overall , 90 % of the rival were under 30 .
This disposition for the Olympics to be dominated by untested adults raise a interrogative sentence : At what age does an athlete ’s performance generally peak ? Given that athletic need change among sports , there are likely a range of answers to this question . alive Science spoke with experts to find out more .

Endurance
At the Tokyo Olympics , 28 - year - oldRichard Carapaz of Ecuador wonthe military man ’s Olympic cycling road race , and 27 - class - oldPeres Jepchirchir of Kenya wonthe womanhood ’s marathon .
" From an survival peak of view , you often peak in your mid - to - late 20s and into your 30 , " said play physiologistGarry Palmer , who runs Sportstest , a sportswoman execution center of attention in Cannock , England . " One of the key reasons behind this is an athlete ’s aerobic capacity , which is the maximum amount of oxygen that an individual can use each min during strenuous usage . "
This capacitance , also live asVO2 max , is quantify as the maximum amount of milliliters of oxygen the body can use per min per kg of bodyweight ( mL / min / kg ) . Top endurance athletes reach well into the 80s and even the XC , compared with an mean nonathlete ’s 30 mL / min / kg .
At 21, American gymnast Suni Lee now sits just around what the average age of the USA Gymnastics team was during the Tokyo Olympics.
Multiple factor repulse aerobic capacity down with years . One 2016 field , published in the journalPLOS One , chalks it up to a lessening in maximum heart rate and the amount of blood pump out per beat . This is accompanied by a decline in the efficiency of valves and muscleman that push blood back to the heart , as well as stiffening of the heart ’s heftiness fibre and the walls of arteries .

Speed
In 2009,Usain Bolt fill in a 100 - time racein a singular 9.58 seconds , win gold at the world championship in Berlin while also smashing his own world record . He was five days unsure of turn 23 . At this twelvemonth ’s Olympics , 24 - class - onetime AmericanSha’Carri Richardsonstands out as a pet for the adult female ’s 100 - m amber .
These athletes ' sprinting transcendency aligns with research by kinesiology professor Edward Merritt and his former pupil Corban Ruiz of Southwestern University . In 2021 , they published enquiry analyse historic period - related performance departure betweenaerobic and anaerobicevents .
In aerobic event , such as marathons , the muscles get enough atomic number 8 to use fat and carbohydrates as their primary fuel . In anaerobic events , like the 110 - m hurdle , there ’s a lack of O and the body alternatively burns glucose stored locally in muscles . This supply is exhausted apace .
Czech shooter Jiri Liptak won an Olympic gold medal at 39.
The researchers used data from the Olympics spanning 1960 to 2016 . They define anaerobic events as those lasting less than two mo and aerophilous event as over five minutes , while events in - between were " mixed . " The average age for peak anaerobic performance was around 23 , compared with 26 for aerobic events , the field found .
Under-30s often prevail in the dash thanks to their muscle . sprinter have an abundance offast - twitch muscular tissue roughage , which generate unretentive , forceful muscle contractions but fatigue swiftly . Slow - twitch muscle fiber are n’t as action - packed but are far more fatigue - resistant . The measure of irksome - twitch fiber remains passably unvarying throughout life-time , but thefast - twitch fiber start to decay with age , set out around your 30s .
Explosive sport like the 100 - m sprint are also brutal on the body and can often lead to vocation - limiting wound , specially in the Achilles tendon , on the lower back of the leg , and hamstring muscles , on the upper back of the peg .
Meanwhile , young sprinters are falcon - like in their physiological reaction , Palmer noted . " Your reaction times are fast when you ’re young , " he said . " If you ’re bet at a short outcome , the start is vital for a strong destination . "
Research suggeststhat reaction fourth dimension peaks at years 24 and decline by about four to 10 msec each class , at least in nonathletes . A 34 - year - old ’s reaction could be up to 100 milliseconds dull than they were a X before — in racing , that could be the difference between victory and defeat . That decay stems fromchanges in heart fibersthat slow the speed at which they behave signals .

Dynamic events
" In active sports like gymnastic exercise , the younger athletes often excel because as you get on , you loseflexibility , " Palmer told Live Science . " You might strengthen your organic structure , but you ’re just not quite as supple . " This declension in flexibility is partially related to a loss of snap andwater in the tendons , as well as increased rigour in roast .
inquiry inThe Journal of Human Sport and Exercise(JHSE ) looked into the age of peak performance at the 2012 London Olympics . It suggested that the average age of a successful male artistic gymnast was 24 years old , compared with 19 year honest-to-goodness for female gymnasts . accord to CEPAR , this disparity between women and military man may meditate difference in physiology and rates of growing , as well as differences in the type of result they compete in .
When it comes to women ’s gymnastics , though , times are changing . Historically , the Olympic gymnasium sport the likes of Nadia Comaneci and Dominique Moceanu , both of whom were age 14 when they won their respective gold . These gymnasts symbolized the " younger , the near " tenet of women ’s gymnastic exercise at the fourth dimension — the cerebration was that untried girl were more flexible than older athlete and unrestrained by the physical changes bring on by pubescence . They were also deemed more fearless , necessitate in a mutant where injury peril is high .
Then , at the Tokyo Olympics , the average geezerhood of the U.S. women ’s gymnastic exercise team tipped over 21 . This year , Simone Biles impinge on Paris at age 27 .
The reasons for this eld increase are varied , and include that the minimal age to contend is now 16 . In improver , gymnasts ' grooming and recuperation regimens have become more scientific . For illustration , Great Britain ’s squad employs a scientistwho pass over gymnasts ' maturation rate , calculating their foretell adult tallness , in part , so coaches can aid guide jock safely through growth jet . In ecumenical , athletes are being well managed than in the past , resulting in more sustainable careers .

Target events
" sport where there ’s a high - science element with less emphasis on physical attribute means elder contender can excel , " Palmer said . " Take shooting and archery — the elderly contender have years of experience to tie on ; plus they might be serene and more well verify their respiration than their young opposition . "
In both of these sport , jock often win in their recent 30 and well into their XL . The JHSE subject area on the 2012 London Olympics showed that the medium eld for a Au - medalist military personnel ’s hitman was 33 . The Czech gunman Jiri Liptak is a more late instance , in thathe gain Tokyo goldin the men ’s trap event at 39 .

Liptak ’s victory also highlights that differences between shooters are fire by experience . CEPAR cites grounds that shooting events that call for stationary targets , such as air rifle , " tend to have lower medial and fair ages " than shotgun events , which involve the more - unmanageable , moving clay targets . As long as you still have good eyesight — or otherwise , good crank — there ’s no grounds you ca n’t extend to stand out into older ages .
In some sports , athletes can even arrive at their stride at older ages : Great Britain ’s Nick Skeltonwon two gold medals in equestrianat 54 and 58 long time old , severally . Age , sure in some events , is just a act .
