You’ll assume athletes who dedicate their lives to protecting match and wholesome would typically dwell longer lives.
Elite athletes are anticipated to dwell longer as a result of people who find themselves match are much less prone to die from heart problems (coronary heart assaults and strokes) and most cancers.
Sadly, our new analysis suggests this doesn’t seem to carry true for male elite Australian soccer and rugby union gamers.
What we found
Our analysis examined survival and longevity in three teams of male elite Australian athletes: Australian Soccer League (AFL) gamers, rugby union nationwide crew gamers (the Wallabies), and summer time Olympic athletes in cardio sports activities with out excessive threat of head damage corresponding to rowing, swimming and triathlon.
Earlier than we dive in, a few definitions: survival is state of constant to dwell, whereas longevity is the power to dwell a protracted life past the common lifespan of individuals within the normal inhabitants.
In our examine, Olympians outlived the overall inhabitants by 3.4 years. In distinction, neither AFL gamers nor the Wallabies lived considerably longer than the overall inhabitants.
On common, AFL gamers lived nearly 4 months longer, whereas the Wallabies lived about eight months lower than the overall inhabitants.
We additionally in contrast athletes who debuted earlier than and after January 1, 1970 to see if survival had improved over time.
As anticipated, the youthful technology had higher survival than the older technology. However there have been comparable enhancements in survival within the normal inhabitants too.
In different phrases, there have been no vital enhancements in athlete survival relative to the overall inhabitants.
These findings are stunning given dozens of earlier research that includes half 1,000,000 elite athletes point out elite sportspeople sometimes outlive the overall inhabitants by 4 to seven years.
Comparisions with earlier analysis
Our findings on the Wallabies are in keeping with earlier research on elite rugby union gamers from Scotland and New Zealand.
However our findings on AFL gamers seem like at odds with a earlier examinewhich concluded AFL gamers had decrease loss of life charges than the overall inhabitants.
Variations in examine strategies are doubtless behind the completely different findings. An important being the participant inclusion standards.
We included all gamers who debuted from 1921 onward, whereas the earlier examine included gamers who debuted at any time, however excluded gamers who died earlier than 1970.
In different phrases, the earlier examine preferentially excluded older technology gamers who died younger. It additionally preferentially included older technology gamers who lived till previous age.
That may bias the earlier examine’s findings in the direction of higher survival and longevity.
Why don’t elite AFL and rugby gamers dwell longer?
The survival profit (how lengthy athletes outlive the overall inhabitants) varies throughout sports activities.
Athletes in non-cardio sports activities (corresponding to weightlifting and discus throwing) don’t get pleasure from the identical survival profit as athletes in cardio sports activities (corresponding to working and swimming).
However the survival profit additionally varies between completely different cardio sports activities, which suggests there are further determinants of longevity amongst elite athletes.
Determinants embody traits of the sports activities (whether or not there’s a threat of head trauma), and options associated to the kind of one that performs these sports activities (corresponding to somebody’s socioeconomic standing).
Sadly, we didn’t have entry to details about reason for loss of life or potential determinants of longevity in our examine.
However we are able to discover some clues from earlier research on skilled soccer and rugby gamers from abroad.
These research discovered these athletes had about 10%-40% decrease threat of loss of life from heart problems, most cancers, and respiratory illness (corresponding to persistent obstructive pulmonary illness), which is in keeping with the concept that elevated health delivers survival advantages.
Nevertheless, the research additionally discovered these athletes had about 140-250% greater threat of loss of life from neurodegenerative illness (like dementia, Parkinson’s illness, and motor neurone illness).
The underside line seems to be the survival profit gained from elevated health is offset by an elevated threat of neurodegenerative illness.

A 12 months on from the Senate inquiry into concussion, what’s modified and what comes subsequent?
We have no idea if this rationalization holds true for AFL gamers and the Wallabies, however additional analysis might discover out by linking athlete knowledge to authorities loss of life registration knowledge.
This kind of analysis could be pricey and time consuming and regrettably, we have been unable to safe the required funding for it this time round.
A chance price?
No matter underlying causes, the very fact AFL gamers and the Wallabies don’t significantly outlive the overall inhabitants is a trigger for concern.
It suggests there’s an alternative price for these athletes.
In different phrases, by taking part in Australian soccer and rugby union on the elite degree, they’ve foregone the advantage of taking part in sports activities wherein athletes outlive the overall inhabitants by 4 to seven years.
From a inhabitants well being perspective, we should take note of this chance price when selling participation in sport.
