It is amazing that Mark Spitz's times have been surpassed by the best women of today. Imagine the best women of today running faster than Lasse Viren did in the 5000m or 10000m? My guess is that swimming is a sport that can be constantly improved by small changes in technique and equipment at the moment whereas in running these changes have a smaller margin for improving performance ....

not sure if this the right answer but in swimming power goes as the square of velocity whereas in running it's closer to linear. So being incrementally more powerful in the water gains you less speed, relatively speaking, than it would running. That same argument, however, would predict that men's and women's cycling performances should be more similar than running performances are (cycling also has a larger exponent) but I don't believe that's the case so who knows.
This.
Power is proportional to veloicty squared, p ~ v^2, thus v ~ sqrt(p). So, dv/dp ~ 1/(2p^2), the rate of change of the velocity with respect to power decreases as power increases, i.e., the marginal value of power output decreases. Intuitively, it makes sense just by thinking about how much more drag there is in water.
Someone who can generate k times more power than you will only be epsilon faster, where for any epsilon we can find the appropriate k.

Simple laws of physics.
When it comes to running, power output is proportional to speed. Therefore, if top women have 90% VO2 max of top men, their velocity is 90%
With swimming, the main force to overcome comes with the viscosity of water. Force is proportional to velocity, power is proportional to velocity squared. 90% of power correspondingly translates to approx. 95% velocity.
In cycling, the difference in times would be even less substantial, since the drag force is proportional to square of velocity. Hence, the power comes as a cube of velocity, meaning 90% of power is approx. 97% velocity.
Etc.
Swimmers have a Reynolds number on the order of 10^6, so inertial drag will dominate over viscous drag - thus for swimming the drag force will also scale with the square of velocity, and power with the cube.
Question for the OP. Are your PRs faster than the women's world record at the distances you run? I am guessing they are not. So you should probably crawl back into your parent's basement and learn some respect.

Why are the Chinese athletes referred to by their first names, while everyone else is referred to by their last names?
Another way to phrase wrote:
Why are men worse at swimming than running?
Because throughout evolution men sought out water to drown themselves and escape their wives. Those that survived and replenished the gene pool were those that could run away from their wives at a rate of 10% faster than the chasing female.
The female that he did not run away from also replenished the gene pool. This female was generally less of a nag. The mystery is why woman still nag men at a high rate. That is the missing link and mystery behind all of this.
I hope this helps. Gotts run!! Bye!!
