Over at Discovery News, Emily Sohn asks the question I've been wondering for the last two weeks. Why are Olympians today better at their sports than Olympians of the past? Why do speed records keep getting broken? Why can gymnasts do more elaborate routines?
I mean, I have plenty of reasonable, speculative answers for those questions. But I hadn't seen them addressed in a factual way. This is great. And fascinating.
The answer, experts say, involves a combination of incremental technological improvements, as well as a growing population of people attempting a larger variety of sports that they start earlier and stick with longer. The mind plays a big role, too, especially when it comes to toppling seemingly insurmountable barriers, like the four-minute mile of the past or the two-hour marathon of the future.
"There is almost certainly a species limit in terms of physical capabilities, and I suspect we might be in the range of that," said Carl Foster, an exercise physiologist at the University of Wisconsin, Lacrosse. "But every time scientists say humans are not going to go any faster, they've been shown to be wrong. You can take that one to the bank."
Through calculations of maximum power output, oxygen use, heart function and other factors, some researchers have attempted to predict what the absolute limits of human ability will be. Much-debated estimates include 1:58 for the marathon (a five-minute improvement over the current men's record of 2:03.38), and 9.48 for the men's 100m.
