A few minutes later, Tan Lulu finished running around the lake and came to the stone table.

"Yes, according to this estimate, you can run 5 kilometers in about 24 minutes. Shen Qi said, "This is not bad among girls, who usually exercise regularly?"

"Life is in motion. Tan Lulu nodded, took out a towel to wipe her sweat, and said, "Eh, Shen Qi, you ran very fast, did you sign up for the long-distance running festival?"

"Reported 5000 meters. Shen Qi pointed to the distance and said, "The five of them plus me are the freshman mathematics department long-distance running team." ”

"It seems that you are reliable, the five of them are not as fast as me. Tan Lulu looked at a hundred meters away, Zhou Yu'an and the five of them dragged heavy steps to this side, yes, the five of them couldn't run, they could only walk.

"I also signed up for the long-distance running festival, 10,000 meters. Tan Lulu added.

Shen Qi was a little surprised: "10,000 meters, it turns out that you are an endurance Ji?" I always thought you were a literary Ji, you sing very well, and you can dance." ”

Tan Lulu asked: "Do you play triathlon? The long-distance run in triathlon is 10 kilometers. ”

Shen Qi was even more surprised: "No, Iron Man, no wonder your skin is so dark." ”

Tan Lulu almost spit out a mouthful of old blood: "Will you be able to chat?"

"Anyway, you have so many skills, why did you go to the School of Government Management? Those who graduated from the School of Government and Management will be civil servants in the future, right? So Tan Lulu, you will eventually become a public servant, and Sister Chunying's position will be taken over by you in ten years, and your image is okay, except for the dark spots on your skin. ”

"If you weren't Shen Qi, I might smoke you. ”

While talking, Zhou Yu'an and the other five came over panting, they were speechless and didn't dare to speak.

"Tan Lulu, you haven't run past me, come, leave your contact information. Shen Qi pointed to Tan Lulu's mobile phone tied to his arm.

Tan Lulu was also refreshed, she took off her mobile phone and opened the WeChat interface: "Shall I sweep you or will you sweep me?"

"I don't have my phone. Shen Qi looked at Zhou Yu'an and said, "Zhou Yu'an, borrow a mobile phone." ”

"Huh?" Zhou Yu'an didn't react for a while.

Shen Qi untied the mobile phone on Zhou Yu'an's arm by himself, turned on the scan code option, and scanned Tan Lulu's WeChat ID: "Come, add a friend, and keep in touch in the future." ”

Tan Lulu glanced at Shen Qi, then at Zhou Yu'an, and left.

Shen Qi returned the phone to Zhou Yu'an and said: "Brother, I can only help you get here, my goddess will attack by herself, after all, you already have Tan Lulu's WeChat account, and any love starts with liking in the circle of friends." ”

"I'm just afraid that I won't be able to catch up with Tan Lulu. "Zhou Yu'an YY is good at it, if he really wants him to go out and pursue the goddess, he is timid.

"There is difficulty, she is a strong endurance Ji, and her physical condition is very outstanding, so Zhou Yu'an, you have to strengthen physical exercise and strengthen endurance, otherwise you will be tortured by her in the future. Shen Qi patted Zhou Yu'an on the shoulder and encouraged.

"If you want to be a girl here, you can't just be able to read, you have to master at least one skill. Zhou Yu'an deeply realized this truth.

"Not really, if you read to the first place in the whole department and the first in the whole school, it's a different matter. The question is, Zhou Yu'an, can you read more than me? Can you read to the first place in the mathematics department? So, run, run out of your life!" Shen Qi told the truth and continued to run.

"Wipe ...... It makes sense. Zhou Yu'an sensed the crisis, he gritted his teeth and followed Shen Qi to practice.

But physical reserve is not an overnight effort, Zhou Yu'an ran until he foamed at the mouth, and he ran seven or eight kilometers a day at most, which was already a challenge to break through his limit.

Shen Qi practiced long-distance running for several days, and the total distance he ran every day was about 15-20 kilometers.

He can run the 5000m in less than 18 minutes, which is a personal PB level in terms of his current sports level and his physical condition.

Since he signed up for the men's 5000-meter individual event of the long-distance running festival, Shen Qi must want to win the ranking, first, for the dignity of the mathematics department, and secondly, I don't know if he can brush up on the points of Xueba? Since sports is set as one of the top ten indicators by the system, achievements in the field of sports can also be brushed up according to normal logic.

There are still three days before the opening of the long-distance running festival, Shen Qi reduced his training volume and only ran 5 kilometers a day to maintain his condition.

The rest of the time, Shen Qi studied the video footage of the men's long-distance running race on the computer and calculated the data.

According to investigations, the top men's long-distance runner in the world today is a black British named Mo Farah, who is the Olympic men's 5,000-meter and 10,000-meter double champion.

Shen Qi repeatedly studied the videos of Mo Farah winning the men's 5,000m at the London Olympics and the World Championships in Moscow, found some patterns, and calculated a set of data.

It was evident that Mo Farah kept his stride length between 1.8 and 2 meters and his cadence between 3 and a half to 4 and a half steps per second during the run.

For the first 10 laps, Mo Farah was not aggressive in his tactics and chose to follow.

In the last two laps, Mo Farah will definitely grab the leading position, stuck the lifeline of the main inner lane, the stride length has increased significantly, and the cadence has increased rapidly.

This is the technical and tactical data that Shen Qi got from the Olympic champion.

Analyzing the physical structure of Mo Farah, he is 1.75 meters tall, and the angle of the ankle joint changes between 19 degrees and 25 degrees when running on the way, and the angle of the knee joint changes range from about 12 degrees to 13 degrees.

This set of data shows that in long-distance running, the ankle joint is under huge pressure, so the limit of the angle change of the ankle joint should not exceed 25 degrees, otherwise it is easy to be injured and hurt for a lifetime.

Shen Qi also noticed that Mo Farah had a very obvious habitual movement, and he had a very small loss of speed when he landed on the ground, and the pace was particularly smooth.

Shen Qi drew on scratch paper, which is a very simple projective geometric common sense, and the final calculation result was: the landing point was about 20-30 cm away from the projection line of the center of gravity of Mo-Farah's body.

Considering that the aerobic metabolism of long-distance running is absolutely dominant, aerobic: anaerobic up to 80%: 20%, and the breathing cycle is controlled at 70-110 times/minute, based on the above mathematical analysis, Shen Qi made his own 5000-meter running technical route manual.

No way, Shen Qi is not a professional track and field athlete, if he wants to achieve some achievements in the track and field field, he can only use some simple mathematical knowledge to improve the efficiency of running.

Theoretically speaking, the data calculated by Shen Qi is effective, as for how much it can be executed at the actual combat level, it depends on the state.

November 2, Yanda Stadium.

The cheerful athletes' march resounded in the blue sky, gongs and drums sounded in unison, and the atmosphere was joyful.

"I announce the opening of the XX Yan University Autumn Long-distance Running Festival!" the school leader led the opening speech, and this year's Yan University Autumn Long-distance Running Festival began.

In the athlete preparation area, the six-person long-distance running team of the freshman mathematics department who have completed the warm-up exercise gathered.

Shen Qi wore sportswear and running shoes, and gave the final mobilization to the five teammates: "Brothers, don't be vain! Look, the girls in Wuyang and Wuyang on the stage are all paying attention to us, and the achievements are in the future! What about your full score in mathematics, do the beauties in the Chinese department know you? Do the beautiful young ladies of the art academy care about you? Only sports are the most direct way for men to conquer women, come, go!"

"Damn, Shen Qi, you didn't say that when you got a perfect score in the math test. "Zhou Yu'an rushed the ducks to the shelves, yes, there are so many beautiful young ladies on the stage, fight!
