Are athletes really getting faster, better, stronger? | David Epstein
Trki, Kody, Cheaty do
When you look at sporting achievements over the last decades, it seems like humans have gotten faster, better and stronger in nearly every way. Yet as David Epstein points out in this delightfully counter-intuitive talk, we might want to lay off the self-congratulation. Many factors are at play in shattering athletic records, and the development of our natural talents is just one of them. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less). Look for talks on Technology, Entertainment and Design -- plus science, business, global issues, the arts and much more.

It's not well known that humans are the best long distance runners on the planet. If you make a race sufficiently long humans can beat horses. Due to our lack of fur, sweating ability, body configuration and high lung capacity to size ratio as well as springy feet, and large glute.

pre historic man
-
i also notice that pre historic had way more muscle power than bolt and can run more than 30 miles per hour

why I don't watch the Olympics
-
it's stopped!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

"have you ever looked at an ape's butt?"

Has he ever heard of drugs?

this guy is obviously a fan boy.... if you really think all the sports achievements in recent years are solely attributed to the fact that coaches and others finally got the brain to specialise their scouting pool or used recent scientific research to expand their training capacities...you're as naive as you look... ever heard of PEDs? no elite athlete you've seen on the screen has won accolades with taking them, they have to because the normal human body can't take intensive training regimes these guys subject themselves to
yes technology has paid a huge part because our knowledge of the material universe has grown exponentially... but going around compiling nice little click bait charts that are awfully obvious doesn't make the new darwin sunshine.... it just means you're explaining the obvious.
Go work at your desk, this talk was boring -
This presentation made a better argument that we've gamed the system not actually improved. Also what about shoe technology? Isn't that at least as important as track material?

They are all black

Bolt still a win
Jamaica a win
A we still a win
Dem girl keep the black ting shining

Notice he put up the 2008 swimsuit technology for the Olympics and yet over 20 swim records were broken in 2012, 2 years after the ban on those suits.
I agree with his general idea - technology, training and steroids do play a large role... but modern people are better athletes.... especially because of improved childhood diets around the world. People are taller, faster and stronger.
Edit: Yeah he mentions specialized bodies for sports... but before Bolt would anyone have taken a 6'5 sprinter seriously? No. -
There all on steriods ask lance

Greeeeat presentation! Does anyone here know which application he uses for the prezi? Obviously not powerpoint!?
-
what a boring presentation 😒

Homologous structures PROVE a common DESIGNER.

One cannot measure distances of greater than about 25 light-years using parallax since we don't know EXACTLY where (not only does the Earth go around the sun, the sun orbits the galactic center, etc. so determining exactly where Earth was 180 days ago is all the more difficult) the Earth was sixth months ago using the Earth's ORBIT around the sun as the base of the triangle. Just ONE light-year has an angle of ONLY 0.017 degrees already! If u think Red Shift measures/accurately gauges distances 2 distant objects, u need 2 know that red shift is QUANTIZED (only at certain energy levels), absolutely ruling out the Dopper Effect explanation, may b caused by tired light, (Light may lose energy naturally as it travels and remember that since light has mass, it is affected by other objects with mass. A solar sail works because light has momentum and therefore mass. If you believe light has energy, and energy is mass according to Einstein, then you believe light has mass.) objects moving @ right angles to us, & when gravity is acting on an object. There's this object moving TOWARDS us that is still red-shifted!!! There's this pair of objects connected with radically different redshifts that proves the big bang wrong. In addition, in the Virgo Cluster of galaxies, near the center, where the velocities are extremely high, the red-shift is somehow washed out. This strongly implies that strong motion DESTROYS the redshift, instead of creating it. A galaxy has even been measured to have a DECREASE of one quantization in redshift, which should be impossible if the universe is expanding and the redshift is due to the doppler effect. YouTube: Stretching the Heavens: A New Cosmology. Google Science vs Evolution Pathlights. We can barely make out PLUTO with our best telescopes and yet we are told astronomers have detected a planet 1,300 or so light-years away?! Think about it. The object MAY be thousands of light-years away but we cannot measure those distances. We are simply TOO TINY, to put it humbly. And yes, there may be no such thing as deep space. Perhaps the "far away" objects are just super-tiny. It's possible. How could we know the difference? The Cosmic Background Radiation is much too cold to have come from the supposed Big Bang. It actually comes from stars. The heavens shall pass away with a great noise... interesting how from a biblical perspective, the big bang is in the future, where the heavens will be passed AWAY, instead of in the past, where it supposedly created the universe.

During the pre-flood world, humans were much bigger and could run much faster as well.
-
just so you know, turning your body from the hips while running is quite inneficient

good video however few drawbacks
1. Jesse Owens record of 10.2 was hand timed, results show the average handtime to Electronic is 0.24, so Jesse Owens time could be between 10.40-10.50 seconds.
2. based on average speed, rather than 90-100 speed, for example Usain Bolts average speed was 23.5 mph but from 90-100 he exceeds 27 mph.
The real gap between Jesse Owens and Bolt, 10 meters.
Going by the cinders to synthetic track conversion (1.5%)
Jesse Owens time would be between 10.20-10.30
Jesse Owens wouldn't even make it through the heats of the Olympics
