Researchers extracted race data for 1553 women and 1641 men from the official World Aquatics database, capturing final times, reaction times, and calculated swimming speeds in freestyle, backstroke, breaststroke, and butterfly events at Olympic distances ranging from 50 to 1500 meters.

The study found substantial reductions in final times across all strokes and distances over the hundred-year span. The most pronounced improvements appeared in freestyle and long-distance events, suggesting these disciplines benefited most from the century’s cumulative advances.

Performance gains were not distributed evenly across history. The largest percentage improvements clustered around specific Olympic cycles, notably 1956, 1972, and 2008. According to the researchers, these periods coincided with major developments in pool engineering, competition regulations, training methodologies, and swimsuit technology, linking stepwise leaps in results to technological and regulatory change in the sport.

Swimming speeds increased consistently in all events examined, and reaction-time analyses revealed significant improvements across Olympic Games during the period in which reaction-time data were recorded, indicating that gains extended beyond raw swimming pace to the start of the race itself.

The authors describe the findings as a comprehensive historical overview of performance change across strokes, distances, and sexes, and suggest the results may serve as benchmarks for coaches, athletes, and sports scientists evaluating long-term trends and preparing for future international competitions. As a retrospective analysis of finalist data, the study documents associations between performance jumps and historical developments rather than testing the causal effect of any single innovation.
