You can find Top 10 Men all time Australian best swims. Let us take long course men freestyle results and count arithmetical mean on how long ago the swimmers showed the result.
It looks as follows
50 m – 2.7 years ago
100 m – 3.7 years ago
200 m – 6.1 years ago
400 m – 8.9 years ago
800 m – 7.7 years ago
1500 m – 12.8 years ago
The method: if one result was showed in 2000 and another one in 2008 than ((2010-2008)+(2010-2000))/2 = 6.0 years ago
Let’s look through all time 25 best results for European swimmers.
It looks as follows
50 m – 2,04 years ago
100 m – 1,44 years ago
200 m – 3,44 years ago
400 m – 6,25 years ago
800 m – 2,92 years ago
1500 m – 9,76 years ago
It is easily to find regularity: longer distance more difficult to beat the result.
Now let’s take results for the very best world runners. Take into consideration All-time 30 best runners all over the world and count arithmetical mean.
It looks as follows
100 m – 8,47 years ago
200 m – 14,69 years ago
400 m - 16,55 years ago
800 m – 12,97 years ago
1500 m – 11,13 years ago
3000 m - 10,87 years ago
5000 m – 7,33 years ago
10000 m – 7,03 years ago
42.195 km – 3,77 years ago
Any regularity? Yes. Longer distance more easy to renew the record.
Runners regularity is on the contrary to the swimmers regularity. Have you got any ideas on that? Does it mean that in the nearest future we will see the real promotion in long distance due to new pharma and endurance train methods?
