不可思议，然后去下载了WMA Age-grading的数据。
以男子全马为例，从22岁到36岁都是factor 100%，也就是说这个年龄段是顶峰阶段。
然后就慢慢减速，要到42岁的时候速度才和18岁时相仿。60岁是和10岁相当的，而不是
18岁。
这个应当是统计的数据，具体到个人还是有差别。 |

发帖数: 4931 | 5 Born to Run was referring to the statistics of NYC marathon in one specific
year I believe. Of course, the author probably selected the statistical data
in his favor. The book is a bit biased for sure.

Even though you are 27, you probably do not know if you already trained
enough to peak.

The way I see it: any middle-aged man is at the beginning of a big downhill,
so he should be able to run faster and faster and faster till he crashes at
the age of 100. Very encouraging :D

provide raw data to you. On their web site, they stated" "On the world level

think that's pretty solid. If you have better data source, please share with

发帖数: 4931 | 21 It's not fair to evaluate the ability of an age group by the world record --
that is just one single performance by
one single individual. What if Haile Gebrselassie sets the world record next
year? Would you say that 38 yr is
the peaking age? :)

发帖数: 164 | 24 There are a few problems with age grading:
1. Very small sample size.
2. Focus on tail behavior (very best) instead of typical behavior (mean or
median) of an age group.
3. World records at peak age are set by pros. Age group records are often
set by amateurs. It is reasonable to deduct that world records at master
level are not as close to human limit (at that age group) as world records
at peak age.
Just imagine a pro becoming a master elite, his training volume/intensity
would decrease a lot. |

发帖数: 164 | 25 They would consider these as outliers and ignore them. For example, Jamaican
-born Olympian Merlene Ottey in 2006 ran the 100-meter dash in 11.34 seconds
at the age of 46. The Age-Graded Tables suggest that performance
corresponds to an Open (ages 20–30) equivalent of 10.122. Since the open
world record for women is 10.49 (by Florence Griffith Joyner in 1988), Ottey
's converted mark seems implausible. In fact, the WMA committee has excluded
certain performances as "nonrepresentative," and not u
