Why do female runners have small b***s?

Question

?

Answer 1

Some have larger boob but they strap them down as not to get in the way. Smaller ones don't bounce as much so there is not as much pain.

Answer 2

These points are all correct, and in addition, running with large b*****s is a little uncomfortable.

I'm not fat, and I'm in pretty good shape but I have relatively large b*****s.  I do jog and do other aerobic exercises, but I have to wear a very strong sports bra, and sometimes two.

Answer 3

b*****s are primarily fat, so a professional athlete, or any individual with a low body fat percentage, will be more or less flat chested.  

Answer 4

I believe it's because b***s are made mostly out of fat tissue and runners are very fit and have mostly muscle. Therefore they will have small b***s.

Answer 5

A combination of 2 factors:

1) Adaptation: Running a lot causes  you to lose weight all over, including your b***s, so skinny runners will have smaller b***s than heavier runners.

2) Selection: the skinniest women and the women with the smallest b***s will be the ones who are the fastest, so the ranks of elite runners will consist of women with that particular body type.

There is this tendency in other women's sports, too. For example, check out figure skating. The women tend to be relatively flat chested, and a number of women have reportedly had breast reduction surgery to improve their ice skating abilities. The last successful figure skater who wasn't rather flat chested was Katarina Witt. If you look at videos of her, she  is ALWAYS wearing costumes with sleeves to them, while other skaters don't have sleeves. It's because Witt needed a strong bra, and the other skaters don't. Witt was known for her artistry and dancing ability. As skating has become more athletic, with jumps emphasized, the larger b***s have become more of a disadvantage in competition, hence those with large b***s have had surgery or dropped out of the sport.

Answer 6

Females with big b***s are not competitive as runners. They have too much fat to carry around. Look at both male and female runners. They are all very thin. To be competitive they have to be.

Answer 7

b*****s are made up of fat. Runners have very low fat to muscle ratio, that is why.

Answer 8

Look i am a female runner and i don't have small b***s i am a size 32A but it also depends on your mother's b***s ( the size) so i will probably end up with big b***s but i am a fast runner but it also depends on the way you run because if you run and you move your body from side to side it can cut the fat and that is how female runners don't have b***s but that is how i don't have small b***s because i run a different way i don't move my abdominal part which is my stomach I hope this helps! :-)

Answer 9

They run because they're ugly.
