Long-term physical performance trends across the five confederations: Evidence from the 19th to 22nd FIFA World Cup editions (2010-2022).

BACKGROUND

Physical performance demands in elite international football have evolved substantially in recent decades, yet longitudinal comparisons across FIFA confederations remain limited.

OBJECTIVE

This study examined long-term changes in physical performance demands among outfield players from five confederations (UEFA, CONMEBOL, CONCACAF, CAF, and AFC) using tracking data from 225 matches at the 2010-2022 FIFA World Cups.

METHODS

Generalised mixed linear models were used to estimate changes in total distance, top speed, sprint (>25 km·h ⁻ ¹), low-intensity running distance (<15 km·h ⁻ ¹), and high-intensity running distance (≥15 km·h ⁻ ¹), with confederation as the main factor and match status, location, and team and opponent strength controlled.

RESULTS

Across confederations, substantial increases were observed in top speed, sprint, and low-intensity running distance from 2010 to 2022, indicating a uniform rise in speed-related demands. In contrast, changes in total distance and high-intensity running distance were confederation-specific. Total distance increased between 2018 and 2022 in AFC, CONCACAF, and UEFA, but showed no substantial change in CONMEBOL. High-intensity running distance declined in AFC, CONMEBOL, and UEFA, while changes in CAF were trivial.

CONCLUSION

These findings indicate that speed-related demands have increased globally, whereas total and high-intensity running demands remain region-specific across FIFA World Cup editions.
