The 2024 Summer Olympics have just kicked off in Paris .
You may be rooting for your favorite elite athletes , hope to witness them shatter records . But as performances improve and records get increasingly harder to outmatch , will jock ever accomplish the limits of what is possible ?
No one has set a new Olympic record for the hammer throw since Yuriy Sedykh (pictured above) did in 1986.
The hammer cam stroke may have already met this fate — no one hasbroken its human race record since 1986 . Yet , athletes oft outdo themselves in other sports , such as the400 - meter sprint .
Biophysical constraints on musculus — as well as other factors , such as response clip — could set a limit on human accomplishment , expert tell Live Science . However , modern techniques and improved sportswear could help athletes continue to unlock new level of operation .

Sprinters like Usain Bolt (middle) can only develop so much muscle before it impedes their performance.
The limitations of muscles
Olympian often boast telling musculus , but great gains do n’t necessarily run to improvements in athleticism . This is partly becausemuscles lose efficiency as they produce .
Kevin Murach , a muscularity researcher at the University of Arkansas , told Live Science that the most - efficient muscles declaration along a line between two tendon . However , as they expand , muscles contract at a less - effective , oblique angle . Overall , more muscle mass produces surplus force-out , but the return diminish as muscle good deal stay on to grow — and brawn will finally approach a concentrated limit on what they can attain .
What ’s more , immense muscle could even curtail athlete in some sports , such assprinting . On one hand , enlarge muscles gift a sprinter with more force and thushelp them master inactiveness — the trend of an physical object at rest to outride at remainder — upon start out . However , " there ’s in all likelihood a peak at which you do n’t want your muscles to be exceedingly large , " Murach said . " You would n’t want to have so much that it became an lynchpin . "
German swimmers present the polyurethane-coated LZR Racer suit, which was eventually banned due to the advantage it gave athletes.
Besides muscle size , an athlete’sdominant type of muscle fibercan affect their performance . There are two maintypes of muscle fibers : immobile - twitching and tiresome - twitch .
" If you attend at a sprinter , they have a high proportion of fast - twitch fibers as fight down to a marathon blue runner , who has a high proportionality of slow - twitching fibers,“John Hawley , an exercise physiologist who guide the Exercise & Nutrition Research Program at the Australian Catholic University , told Live Science . firm - twitch fiber are richer in energy shop , produce more volatile movement and fatigue more quickly than the dense - twitch multifariousness , he said .
This inflict a speed limit on high - endurance sports , such as long - aloofness running . Because of this , " I do n’t lie with if we will ever be at a place where you may track down a endurance contest at a sprinting stride , " Murach said .
The influence of technique and gear
Muscles set a cap on how concentrated athletes can work , but performance also depends on what athletesdowith their muscle .
In the 1968 Olympics , Dick Fosbury used aninnovative strategy for the high jumpthat literally conjure the bar . rather of soaring forward over the pole , he rotated his body midflight . The half-witted jump enabled him to arc his soundbox andlower his shopping center of massso he could leap over the rod with less travail . Five years later on , Dwight Stones perfect the " Fosbury flop " andsurpassed the high - parachuting worldrecord using this method .

" Now you wo n’t chance a high sweater in the humans — you may discover one out of 100 — who does n’t use that proficiency , " Hawley said . This means that a physical peak does n’t inevitably keep record from being break in the future .
Improvements in sportswear can also boost carrying into action significantly . For example , jock wear polyurethan - coated swimsuitsbroke 25 Earth recordsin the 2008 Olympics . One hypothesis is that " the polyurethane panel laminated over the fabric could foreclose the air in the fabric from break loose from the costume [ swimsuit ] when the athlete entered the water,“Ada Ferri , a material engine driver at the Polytechnic University of Turin in Italy , told Live Science in an email .
A flyspeck amount of trapped strain might have given the dissident an bound byproducing some buoyancy , she suggested . " As races are won by a few hundredths of a 2nd , even buoyancy of a few millimetres can be decisive , " Ferri said . polyurethan bathing costume were laterbanned from competition , in 2010 . However , this has n’t stopped jock from surpassing records , suggesting swimmers ' actual performance still has n’t hit a ceiling .
Since 2016 , shoes fit out with carbon copy - plated innersole can give runners an advantage , Ferri said . This eccentric of footwearlimits energy going through the shoe ’s shock - steep midsole , meaning the base runner has to put in less body of work to run quicker . World Athletics , an organization of caterpillar tread - and - field federations , allows athletes to compete with these shoe as long as thefoam stem is no higher than about 1.6 column inch ( 4 cm ) , so it ’s possible this sportswear could lead to new running records .
More broken records to come?
Other factors can influence performance , such as anathlete ’s diet , theirpsychological stateor their mode of training .
For instance , cyclist and runners train at high ALT , driving their bodies toproduce more O - carrying red descent cells . However , Ferri argued that these extra factors give rise gradual advances in operation . Huge bounce tend to be link to breakthroughs in plan material and equipment , she said .
Historically , more military personnel than woman have vie in sports and Olympian events . So , most of the inquiry about gymnastic achievement has been base on male figure and there is a shortage of data point on female physiology . Learning in force training method acting geared specifically toward distaff athletes could get about the great performance gain , Ferri hypothesized .
" For the first time at the next Olympics in Paris , the percentage of female and manly athletes willbe [ nigher to ] adequate , " Ferri say . The more distaff athletes who compete , the more probable that some will surpass premature milestones , so an even split up between the sexes might lead to more disordered record book .
Hawley noted that historically , most advances in athletic performance were breach through test and erroneousness , and scientist only later began studying the reasons why they occur . But science now has a farm presence in variation .

With more data monitoring , " we will have a goldmine of info that athletes and coaches can use to make informed decisions about strategies in education and competition , Ferri said . This might streamline Modern breakthroughs that crowd athletes to place new all - time C. H. Best .
