Why don t female marathon runners have breasts?

As I exercise vigorously for a long time.

Hormones are grown to the legs.

And just on the muscles.

Nothing to use. Running or protective underwear is more useful.

Yes, I am a long-distance runner, I have to run a few laps every morning, and I have been sagging my breasts for a long time, but since using Bao Yifeng products, my sagging breasts are really getting better, and now my breasts are fuller than before.

If you carry dozens of pounds of flour on your back and compare yourself with no back flour, who is faster? Who's tired?!

The landlord just asks a question, what are you scolding people for?

1.Marathon runners need to be selected for a lighter weight and longer muscles, because this type of person usually has better endurance, because they are light, they will not have to run hard.

2.Marathon runners usually exercise so much that they can't gain weight.

Not all marathon runners are skinny.

Only thinner people can become marathon team members.

Why are some people in the world so talented that we can't hope for it?

Running is the most convenient fitness activity, but many beauty-loving girls dare not run, for fear that the more they run, the thicker their calves will become. But this is not absolute. Sprinters have thick calves, and marathon runners have strong and slender calves and more beautiful leg lines.

These are caused by differences in running form and intensity.

These are caused by differences in running form and intensity.

Don't look lean, it's all lean meat.

Low fat content, good stamina.

Boss, can you still run if you're fat? Stupid.

Can that be the same Long-distance runners are aerobic exercises that burn fat and muscle, and although cycling is also aerobic exercise, it is more anaerobic in terms of leg strength, and since the legs are anaerobic, of course the legs will be thicker than the legs of marathon runners.

Cyclists also have thin legs, and of course the muscles of different members of the cycling team are different, and the legs of sprinters may be thicker.

I have observed professional long-distance runners with thin calves and thick upper thighs.

Cycling requires a lot of explosiveness, just like sprinting, and many sprinters have very thick legs. However, long-distance running is dominated by relatively gentle aerobic exercise, and there are very few thick legs.

I want to find a boyfriend, I want to be powerful.

Because marathons are long-distance runs that consume muscle.

Let me think for a moment why this is.

This statement seems a bit strange at first, no matter what sport there will be a world record, but this statement is really not wrong, there is indeed no world record in the first marathon.

The marathon was originally set up to commemorate the soldiers who died because of conveying the news of the victory in the Greco-Persian War, because the marathon at that time was not very formal, and it was not like other track and field sports, the venues of the races were uniformly regulated and had unified standards, because the marathon was too long, so most of the tracks used in the race were car roads in the city, cement roads, asphalt roads, and even dirt roads in the countryside. And the competition is often held in different countries and places, so there is no unified standard, because the standards are different, so it cannot be called a world record, only the best result.

Although there is no world record for the marathon, there are women's marathons, they are the mixed gender marathon world record and the pure women's marathon world record, the mixed gender marathon refers to the marathon of men and women together, because the marathon has always been carried out by men and women together, so that male athletes will run in front of female athletes, playing a leading role in female athletes, such a result is a mixed gender women's world record. And the pure female athlete is not only female athletes, but let the female athletes run for 20 minutes first, so that the male athletes will not affect the performance of the female athletes, and the result is a pure women's marathon world record.

Later, the IAAF noticed this problem and imposed strict regulations on the marathon course, so there is now a world record for the marathon.

The men's race was Kenya's Paul Tegart, who beat the world best in the men's marathon held by Moroccan-born American athlete Kannuchi with a time of 2 hours, 4 minutes and 55 seconds, and improved it by 43 seconds! The latter was created at the London Marathon on April 14, 2002.

The main reason is that the marathon course uses general city roads to pass through oil roads, stone roads and even dirt roads, and the difference in the slope of the fold and the undulation is relatively large, and the race time is also available in all seasons of the year, so it is difficult to determine the world record because there is only the best result.

Since the marathon is held on a regular road with different courses, there is no world record, only the world best as the record for the performance of the champion.

It's not that there are no world records, it's just that there may not be any records in the world at the time.

Marathons have been recorded in the past, and there have been no marathons in the past.

I think it's because the marathon record is so hard to determine, so I don't.

Marathon runners don't vomit in the lower part when they run, because they practice for a long time, and then the body works well.

Why don't marathon runners vomit when running? This person has been trained, there should be a method, right?

The reason why marathon runners don't take off their walks while running is because they have passed special exercises.

Why do marathon runners run? Lower. No squatting. Check it out on the Internet.

Because marathon runners exercise regularly, their muscles are also tighter.

Marathon runners run when they are, very evenly.

At that time, athletes did not apply the lower part when running, because they would pant for breath, and if they were not able to breathe, they would be prone to split their breath, which was very bad for the body.

It's because all the energy of the athlete is built on the limbs.

Mom said that the athlete packed the picture when running.

Why do marathon runners run faster in the lower part of the run?

Why are all female athletes in swimming an "airport"? Does this exercise hinder normal development? In fact, this is not the case, the swimmers wear very professional swimsuits, and in order to reduce the resistance of the athletes in the water, the swimsuits must fit the athletes' bodies well.

It generally represents a different starting area. In order to ensure the safety and fairness of the blistering, the marathon is generally divided into different starting areas according to the registration results of the runners, professional athletes are in the front, the registration results are relatively high, and the slow ones are relatively backward.

Contest Rules. In the marathon, water and other beverages are served at both the start and end of the race, while along the race route, there are drink stations every other kilometer. Water and beverages are kept within easy reach of athletes as they pass by, athletes can bring their own drinking water, and beverage stations can be set up where they request them.

The drinking water and wet sponge stations are set up between the two beverage stations. There, long-distance runners and race walkers can get drinking water as they pass by, and they can squeeze water out of a sponge to rinse their heads and cool them. In addition to this, athletes cannot get drinks from elsewhere on the race line.

It can be said that "water" is the most regulated part of the marathon. In addition, athletes can race along the correct route under the supervision of the referee, and if there are special reasons, they can leave the race route under the supervision of the referee, but if they do not leave under the supervision, they will be disqualified.

Take them to the starting area separately.

The first marathon in China's history was held in Nanjing, and since the introduction of modern sports to China, the first recorded marathon in China was held between Nanjing and Zhenjiang. The last section of the track, that is, the section from Zhongshan Gate to Xinmofan Road in Nanjing. November 17, 1910 (the 16th day of the 10th month of the lunar calendar), ".

The Times issued a preview of the competition: "All newspapers and museums: the long-distance race walking will start from the top of Jinshan Mountain in Zhenjiang and end at the memorial tower of Nanjing Quanye Association. The seventeenth (day) is full, and the nineteenth (day) arrives at the venue". At the end of the Qing Dynasty and the beginning of the Republic of China, "race walking" was a common name for running competitions.

There are also many differences between the past and the present marathon: the race is divided into three days, the participants are mainly teachers from various schools in Nanjing, and the course is divided into three incoherent sections: the first day from Zhenjiang Jinshan to Gaozi Town, the distance is about 12 kilometers, and the second day runs to the outskirts of Nanjing, the distance is about 20 kilometers.

On the third day, we will rest in the morning and start from Nanjing Chaoyang Gate (now Zhongshan Gate) to the Quanye venue (near the current Nanjing Xinmofan Road) in the afternoon, a distance of about 10 kilometers. There are more than 10 people participating in the race, except for the players who quit and foul in the middle of the race, 6 people ran the whole course and reached the finish line at the same time, in no particular order.

The specific meaning of the numbers of each organizing committee is different, but they are all used to distinguish the starting area.

They are usually arranged according to the order of special invitation - men's and women's full course - men's and women's half course - other groups - mass run.

A stands for the men's marathon.

B stands for Women's Marathon.

c stands for men's half marathon.

D stands for Women's Half Marathon.
