Athlete Body Size Changes Over Time

In the past century, humans have undergone significant changes in body size and shape, thanks to improved health and nutrition. This change is also evident in the world of sports, where elite athletes today possess distinct body sizes and shapes compared to their predecessors. These changes are even more pronounced than those observed in the general population, with athlete body sizes becoming increasingly specific to their respective sports.

Advancements in health and nutrition knowledge, as well as athlete training methods and sports nutrition, have contributed to this transformation. Additionally, increased training time and opportunities have made sports more accessible to a wider range of individuals. This has resulted in a larger pool of talented athletes who are better suited to their sports in terms of both ability and body size. It is safe to say that modern athletes are vastly different from those of the past.

To better understand these changes, we have analyzed data from champion athletes over the past 100 years. Here are some key findings from our studies:

Athlete Changes Over Time

  • 100m Olympic champions: Winning sprinters have generally become taller and heavier over time.
  • Marathon Winners at the Olympics: The body sizes of winners have varied significantly, especially prior to the participation of African athletes in the sport.
  • Swimming 100m freestyle Olympic champions: Winning swimmers have generally become taller and heavier.
  • All-round Olympic Games gymnastics winners: Winning gymnasts, particularly females, have become shorter, lighter, and have lower body mass index (BMI).
  • Olympic Games Cross-Country Skiers: There is a trend of increasing height and weight over time, with BMI remaining fairly consistent.
  • Wimbledon Winners: Champion tennis players have consistently been getting taller.
  • Tour de France Winners: We explore how the height and weight of winners have changed over time.
  • FIFA World Cup players: A comparison of player characteristics in 2002, 2006, and 2018.
  • Olympic Football Players: A comparison of characteristics across different Olympic Games.
  • NBA Players: We delve into the changes in height and weight among NBA players over time.
  • AFL Players: We examine the height and weight changes among Australian Rules Football players in the last decade.

A: Various factors influence body size changes in different sports, including skill requirements, training methods, cultural factors, and genetic diversity among athletes.

Q: How do these changes affect athletic performance?
A: Changes in body size and shape can have both positive and negative impacts on athletic performance, depending on the sport. Adaptations to body size can enhance certain physical attributes required for specific sports.


The study of athlete body size changes over time provides valuable insights into the evolving nature of sports and the impact of various factors on athletic performance. By analyzing data from champion athletes, we have observed significant transformations in body size and shape across a range of sports. These findings shed light on the dynamic interplay between genetics, training methods, nutrition, and other variables that shape the modern athlete.
