How athlete performance changed over the last 50 years - KineVision Blog<br>KINEVISIONBlogBook DemoPricingSupportDownload

It is easy to say athletes are faster, stronger, and more explosive than they used to be.

It is harder to say how much better.

Track and field gives us one of the cleanest ways to measure that question. A 100m race is still 100m. A high jump bar is still a high jump bar. A discus still lands where it lands. The events are not perfectly unchanged, because surfaces, shoes, training, competition depth, and athlete access have changed, but the scoreboard is unusually clear.

So we compared the world record that was standing on January 1, 1976 with the current listed world record as of May 20, 2026 .

The result is not one simple story. Some records barely moved. Some moved a lot. Some moved because athletes became better. Some moved because the sport around the athlete became better.

For running events, improvement means the record got faster. For jumps and throws, improvement means the record got higher or farther. Historical hand-timed sprint marks and pending road-record ratifications should be read with that context.

The comparison

This table uses 10 events across men's and women's track and field: sprints, middle distance, marathon, jumps, and throws.

The biggest jump is not in the 100m

The 100m is the event most people think about first, but it is not where the biggest percentage gains happened.

The men's 100m record moved from 9.95 to 9.58, a 3.7% improvement. That is enormous in a race decided by hundredths, but it is still a small percentage change. The women's 100m record moved from a hand-timed 10.8 to 10.49, a 2.9% improvement.

Compare that with the marathon. The men's mark improved from 2:09:12 to Sabastian Sawe's 1:59:30, which World Athletics listed as a world record pending ratification after the 2026 London Marathon. The women's mark improved from Jacqueline Hansen's 2:38:19 road best in 1975 to Ruth Chepngetich's 2:09:56 in 2024.

That is the clearest example of the sport changing around the athlete: deeper professional fields, faster courses, better pacing, better fueling, more global participation, and a new era of racing shoes.

Some records are old because they were extraordinary

Not every old record means the event stopped progressing.

Bob Beamon's 8.90m long jump from 1968 was so far ahead of its time that Mike Powell only moved the world record by 5cm in 1991. The chart makes that obvious: men's long jump has the smallest percentage change in the sample.

The same pattern appears in a different way in women's throws. The current women's discus record, 76.80m by Gabriele Reinsch, was set in 1988. The women's shot put record,...
