Being an elite athlete is hard work, but so too is being a fan. Data collected from roughly 7,000 smartwatches in France shows just how much heart rates soared at key moments of the country’s 4-2 victory over Croatia in the World Cup Final on Jul. 15.
French consumer electronics company Withings, which makes connected health products under the Nokia brand, collected and anonymized the data from Nokia Steel HR watches. Heart rate peaked after France broke a 1-1 tie in the 38th minute when Antoine Griezmann converted a penalty kick.
