Generally speaking, when the percentage of fat decreases, the running performance always improves

.

In addition, with their own weight, the impact on performance is also different

.

For example, a runner with the same 4-hour strength of the whole horse can improve his performance to 18 minutes when his 75kg is reduced to 70kg, and 22 minutes when his 60kg is reduced to 55kg

.

He is 1.67 meters tall and weighs 52 kg

.

It was put forward by Professor tanaka of Fukuoka University in Japan

.

World champion’s BMI all runners with the right race weight have low body fat levels

.

It is concluded that the BMI of elite runners in Malaysia is generally between 17 and 20, of which the BMI of male elite runners is generally within the range of 19 ± 1, and the BMI of female elite runners is even lower, around 19

You can check whether your weight is up to the standard ~ men’s standard weight table women’s standard weight table note: this table is said to be specially designed for Asian people’s body shape, and the fluctuation of 10% is normal ~ for your reference only

.

In addition, due to the higher ratio of skin area to body weight, light weight athletes have more advantages in heat dissipation efficiency, and can keep running at high speed for a long time without worrying about overheating and slowing down

.

When you have enough training, your weight will naturally decrease and your performance will naturally improve

.

As a result, if you are malnourished or your weight is not at the basic level of health, you will not achieve good results

.

Nine years later, in order to cure metabolic syndrome, Tanaka, whose weight reached 64kg, ran horses again, with a score of 3h30m3s

.

It is a standard commonly used in the world to measure the degree of obesity and health

.

These are the key factors restricting the 30-year-old horse runners.

.

From 1996 to 2011, the BMI of the world’s top 100 professional runners is distributed in the analysis of elite athletes’ body data in Japan and Kenya

.

These runners are light weight, but the fastest of them are the lightest

.

BMI index (body mass index, body mass index, BMI) is a number obtained by dividing the number of kilogram of weight by the square of the number of meters of height

.

Of course, if you want to catch up with the results, it’s necessary to lose weight, not to lose weight If you want to pursue results, then a lot of exercise is necessary, which also means that the weight will be reduced naturally

.

Body weight Pb diagram people around the age of 30 run marathons, not only depends on weight and energy consumption, there are more factors

.

This incredible efficiency will be fully reflected when he drives at full power and speeds up 2:47 at the end of the marathon

.

For every runner, it is the amount of fat in his body that determines how close his weight is to the race weight

.

A study has shown that there is not much relationship between the weight in the 30s and the performance of the marathon, which not only depends on the weight and energy consumption, but also has more factors; but after the age of 40, the relationship between the two is very close, roughly every 1kg weight lost, the performance will increase by 9 minutes

.

When the BMI is lower than 18.5, the body will not be able to bear the risk of injury due to the intensity of training, but also prone to disease and weakened resistance

.

At the age of 50, he continued to be a Pb player and finished in 2h38m48s

.

Every ounce of weight on him has its own use

.

Under the same BMI (body mass index), the runners with 1.92m in height emit 32% more heat than the runners with 1.74m in height

.

In addition, the research on 12 elite men’s and 12 elite women’s runners in Ethiopia shows that the correlation between fat level and race performance is 80% for men and 78% for women

.

Hongxiao Tanaka, MD, Professor of Physical Education Department, Fukuoka University, Japan, mainly studies sports physiology

.

For example: the problem of pace in marathon, the problem of improving muscle strength, the problem of basic training

.

Running professors are dedicated to providing training, rehabilitation and equipment for runners

.

At the same time, the fat content of middle and long distance runners was counted: it was found that the body fat rate of excellent marathon runners was very low, which were 10.3% for men and 15.2% for women

.

There is also a critical point for weight to affect running performance

.

The weight of the girls with the same height of 160cm is about 48kg

.

Most of us know that weight affects running performance

.

According to the table, if you now have a full horse record of 4 hours and a weight of 70kg, if you lose 65kg, the whole horse time can be as fast as 3 hours and 41 minutes! But please don’t be happy too early, remember this 5kg can only reduce body fat! If it’s just water loss or muscle loss, it won’t achieve this effect! The latest running standard weight comparison table every runner has his ideal race weight

.

The figure below is a comparison table of standard running weight for amateur runners

.

Body fat weight is affected by many uncontrollable factors, including age, gender and gene

.

However, if your percentage of fat decreases and your running performance also decreases, then you have lost too much weight

.

Source: running

.

At the age of 47, he controlled his weight at about 50kg and broke through 3 with a score of 255

.

There is a popular saying in the running circle: if you lose 1kg, you can improve your whole horse performance by 3 minutes

.

The height and weight of the competitors were reduced by 3.3cm and 3.4kg respectively

.

when the runner lost 61 kg, the marathon performance would be improved to 3 h 19 m 9 s (10 m 51 s); when the runner gained 69 kg, the marathon performance would be reduced to 3 h 40 m 41 s (10 m 41 s)

.

Take kipchogg as an example

.

Taking a runner with a weight of 65 kg and a marathon performance of 3 h 30 m as an example, he predicted that the maximum oxygen uptake would be 44.6 ml / kg / min

.

The lighter the weight, the less weight each step needs to lift from the ground, the less energy consumption, and the higher the efficiency of running

.

For women, too light weight will inhibit female hormone secretion, resulting in endocrine disorders, but affect physical health

.

In the process of pre competition training and nutrition supplement, the weight of your muscles and bones will not change much, but the weight of your body fat is likely to drop significantly

.

His score was 411

.

At that time, he weighed more than 50 kg and ran for only half a year

.

Everything has a degree, so the lighter the weight, the better

.

The better your marathon performance, the more progress you will make if you lose weight

.

However, the skin area of the larger runners is smaller than their weight, and their body temperature rises faster, so they need to generate 42% more heat

.

By comparing the top 100 marathoners in the world ranking from 1990 to 2011, it is found that the height and weight of the long-distance runners show a significant downward trend

.

It is estimated that the influence of genes is 64% among the factors that affect the minimum level of fat needed by everyone to keep fit

.

Therefore, there is no need to pay attention to your weight

.

If your body fat level becomes too low, your health and running performance will be affected

.

In most cases, a runner’s race weight is the minimum weight he can achieve without overtraining and taking in enough energy to maintain the best running performance and recovery

.

Professor Tanaka was 37 years old

.

According to this ratio, the marathon runner should be about 57kg, taking the 175cm high runner as an example
