The 2024 Paris Olympics marked the second Summer time Video games because the onset of the COVID-19 pandemic. Western Pacific nations, equivalent to Australia, China, Japan, New Zealand, and South Korea, excelled within the Olympics, significantly in profitable gold medals. This success could also be partially attributed to their stringent pandemic measures and a ‘COVID-cautious’ strategy.
These nations had been beforehand acknowledged for his or her efficient responses to coronavirus illness 2019 (COVID-19), together with strict measures like border closures, lockdowns, and masks mandates. These efforts have been related not solely with diminished extra mortality but additionally with a possible psychological and bodily benefit in worldwide competitors. These efforts had been discovered to successfully cut back extra deaths because of COVID-19 as in comparison with these reported in different areas.
In a latest examine posted to the medRxiv* preprint server, researchers in Australia and New Zealand investigated the connection between extra mortality, COVID-19 responses, and efficiency in the course of the 2024 Olympic Video games in Paris, France.
In regards to the examine
The researchers of the present examine analyzed the efficiency of 18 nations within the 2024 Paris Olympics, together with New Zealand, Australia, France, the Netherlands, Italy, South Korea, Japan, China, Germany, Hungary, the USA, Nice Britain, Jamaica, Kenya, Cuba, Brazil, Spain, and Canada.
The evaluation thought of Historic Olympic success, residence nation benefit, the consequences of time zones, extra mortality from COVID-19, and gross home product (GDP) development. One other variable thought of was the variety of signatories to the Nice Barrington Declaration (GBD), which displays a nationwide stance towards strict pandemic measures. Any nation that signed the Nice Barrington Declaration (GBD), which advocated towards widespread lockdowns and supported the event of other approaches to pandemic administration, was additionally recorded.
Medal counts for the 2012, 2016, 2020, and 2024 Olympics had been obtained from official sources. Nations had been chosen based mostly on their constant prime efficiency within the earlier three Olympics, excluding Russia and Ukraine, because of diminished staff sizes in 2024.
Every nation was assigned sure factors based mostly on its efficiency, with changes made for components like residence benefit and time zone results. Based mostly on accessible information, the affect of nationwide extra mortality in the course of the pandemic was additionally decided. GDP development information was collected for 2020-2023, and the variety of GBD signatories was estimated.
The evaluation was performed utilizing backward stepwise linear regression, which allowed researchers to determine key components influencing medal counts. Moral approval was not vital since solely publicly accessible information was used for the present examine.
Examine findings
The very best predictor of medal success on the 2024 Paris Olympics was previous efficiency in the course of the 2012, 2016, and 2020 Olympics, as nations that carried out effectively in these video games continued to excel in 2024. Decrease extra mortality from COVID-19 was additionally related to extra gold medals, thus indicating that international locations with fewer pandemic-related deaths had been extra more likely to win extra gold medals. Nevertheless, this affiliation was most pronounced for gold medals particularly, fairly than complete medals or minor medals.
4 international locations with 10% or extra extra mortality between 2020 and 2023 obtained fewer gold medals than predicted based mostly on their efficiency in three earlier video games. Comparatively, 5 international locations with lower than 6% extra deaths throughout the identical interval gained gold medals than would have been predicted based mostly on their previous efficiency.
The house-country benefit was additionally vital, particularly for complete medal counts, however much less so for gold medals. A adverse affiliation was additionally noticed between the variety of signatories to the GBD, which opposed strict COVID-19 measures, and the variety of gold medals gained, thus suggesting that international locations with extra signatories had been much less more likely to win gold medals. This highlights a possible psychological affect on athletes, the place a ‘COVID-stoical’ mindset might have negatively influenced efficiency.
Different components, equivalent to GDP development in the course of the pandemic and time zone results, weren’t considerably related to medal success in Paris.
Conclusions
The present examine establishes an affiliation between pandemic responses and Olympic success in Paris 2024. Whereas causation can’t be definitively confirmed, the info means that international locations with decrease extra deaths, equivalent to Western Pacific nations, outperformed expectations, which can be linked to each the bodily and psychological advantages of stricter public well being measures. Nations with fewer extra deaths, equivalent to Western Pacific nations, outperformed expectations, which can be attributed to their ‘COVID cautious’ strategy. Thus, stricter public well being measures might have had a optimistic affect on athletes, each bodily and psychologically.
The present examine’s notable strengths embody figuring out extra mortality as a major predictor of gold medal success. Nevertheless, the examine is related to sure limitations, such because the potential for unassessed confounding components, together with Russia’s absence from the Olympics and the distribution of latest Olympic occasions.
Moreover, whereas decrease extra mortality correlated with extra gold medals, it’s unclear if this relationship is because of diminished an infection, psychological resilience, or different unmeasured components. Future analysis is required to additional discover the psychological results of pandemic responses on athletes and to determine another potential confounding components.
