World Cup Fever Study tracks how football viewing stress impacts fan’s bodies

Crowds rise, voices sharpen, and a match can turn on a single kick. Now a team at Bielefeld University wants to know exactly what those moments do to the body. Its Football Fever Study, launched for the 2026 FIFA World Cup, is recruiting supporters of all national teams to track how match events affect heart rate and stress levels. The project uses smartwatch data to follow what happens during games, then compares those bodily changes with what is unfolding on the pitch. The appeal is broad by design. Anyone using a device from one of 13 supported brands can take part. The study records heart rate, stress, movement and sleep automatically through the watch, and the researchers say the data are collected anonymously and in line with data protection rules. That reach has widened quickly. When the study opened on 28 May, only Garmin devices were compatible. Since then, the team has added 12 more brands: Apple Watch, Google Pixel Watch, Samsung Health, Withings, Fitbit, Oura, Polar, Amazfit, Coros, Whoop, Xiaomi Mi Fitness and Wahoo. …

A new analysis published in the journal PLOS One suggests that soccer teams perform better when they spread their play unpredictably across the entire field rather than focusing attacks in familiar areas. The research examined how ball movement patterns relate to match outcomes using data from professional competitions. “Soccer is low-scoring, so a couple of moments can swing a match, and simple statistics like possession or shot counts do not always capture who performed better,” said Dr. Sergiy Shelyag, an associate professor in applied mathematics and data science at Flinders University. “Our approach measures how unpredictably and widely a team moves the ball across a match.” Football pitch divided into 30 zones.
