Data Reveals How Footballers' Bodies Have Transformed Over Half a Century

Modern professional footballers are physically transformed compared to their predecessors from the 1960s and 1970s, with data showing significant changes in body composition and athletic conditioning over the past 50 years. Players today are generally taller, leaner, and more muscular than legends of previous eras such as Pelé or Gerd Müller, driven largely by advances in sports science, nutrition, and training facilities. Interestingly, the data also shows that some players are deliberately restricted from excessive weight training, as too much muscle mass can hinder agility, endurance, and technical performance on the pitch. The findings raise a fascinating question about how icons of the game's past would fare if they competed against today's elite athletes such as Erling Haaland or Cristiano Ronaldo at their respective peaks.
