Because he was late for a nap, Liu Huaxing chose to ride a bicycle when he rushed to school.

"Huh, he said harshly, he didn't take me honestly." Yang Xiaoxiao sat in the back seat of Liu Huaxing's bicycle and said with a triumphant smile.Liu Huaxing shook his head helplessly: "Then I can't let you run behind, right?"

"Oh! You don't have to walk by yourself. It's comfortable." Yang Xiaoxiao stretched out in the back seat and smiled. At this time, the bicycle suddenly smashed on the road. A bump made Yang Xiaoxiao scream and hugged him quickly. His waist.

"Don't you have to stop?" Liu Huaxing smiled gleefully, and Yang Xiaoxiao slapped him hard from behind: "On purpose?"

Liu Huaxing did not reply, and rode forward silently.

In his heart, he was still very happy, Yang Xiaoxiao would come to think about taking care of him when he was tired.Although Qin Yulu might have this idea in her heart, she still didn't put it into practice, so in the end it was now this end.

"By the way, it's the first time I've seen you in such a long time and said I'm tired." Yang Xiaoxiao stretched out his hand and tugged at the hem of his clothes behind him and muttered, "I thought you were a superman, and you would never be tired. Are you successful When?"

"It's not tired. I have extra physical strength. I'm just worried that it will affect the long-distance running in the afternoon, so I just take a break." Liu Huaxing said disapprovingly, "Now that I am full of energy, can I have a good long-distance running in the afternoon?"

"Well, come on, don't force yourself, it doesn't matter if you don't get the award, you are not a sports student." Yang Xiaoxiao replied behind him.It's a pity that Liu Huaxing couldn't see her expression and posture. Although the faces of people around him could be seen full of envy, he actually didn't feel anything...

"I know." Liu Huaxing replied, and soon the school was in sight.

After stopping the bicycle, Yang Xiaoxiao gently jumped off the car and patted him on the back: "I'll pass first."

"I'll see you later." Liu Huaxing smiled slightly, and Yang Xiaoxiao gave him a playful smile, then put his hands behind him, and jumped to their class area.And Liu Huaxing went to park the bicycle, and then came to their work area on the playground.Ren Xia came over immediately after arriving in class, and asked with concern: "How is it, how is your health?"

"Fortunately, it may be that I ran too hard in the morning and I was a little tired. Just take a rest." Liu Huaxing nodded. At this time, he saw Qin Yulu behind Ren Xia, looking at him with worry.

"That's good, go get ready for a warm-up, the two-kilometer project will start soon." Ren Xia exhorted.

So Liu Huaxing came between Qin Yulu and Yang Xiaoxiao and handed them his coat: "Help me watch."

"Come on..." Qin Yulu waved her small hand and smiled. Yang Xiaoxiao just looked at him with her chin on the side and smiled. She had already said that before.So Liu Huaxing nodded and came to the arena to warm up.

The advantage of the two-kilometer is that it can be held in two times, with more than 20 students running a round together, and then ranked according to their scores.After a brief warm-up, Liu Huaxing came to the arena and started a two-kilometer run.

Although he ran more than ten or even twenty kilometers while jogging, he tried the 2,000-meter long-distance race for the first time. He was a little rusty in experience, but he only knew one thing: he didn't like long-distance running.

He likes jogging, because jogging can run slowly at his own pace, and he can run very leisurely and comfortably, but the two-kilometer long-distance running is not a jogging at all, but a kind of racing. You must go as fast as possible. Run, run in a hurry.

During the long-distance running, Liu Huaxing had no feeling of enjoyment at all. He just ran as fast as possible within the limits of his physical strength.Because he has run many long distance runs, he knows his physical condition, how fast he can finish the two kilometers, as long as he runs on that basis first, and then sprints at the final stage.

Liu Huaxing's physical fitness is very good. At the beginning, he did not rush to speed up. Instead, he ran at his own pace and kept breathing evenly, and then let everyone else run ahead of him.But in fact, the running skills of these people are really stretched.Many people run recklessly with their heads up when running, but this is actually a very low-level mistake.

When really running, the upper body should lean forward, so that the center of gravity will lean forward and drive the body forward.

Many students started to run very fast, and then their breathing became slower and slower when they could not keep up, but Liu Huaxing was the opposite.In the early stage, the body is gradually active by running at a slower speed, and then the speed is increased little by little.

The next thing is very interesting. Liu Huaxing overtakes the people in front of him one by one. After the third lap, he has already ran to the first position. On the fourth lap, he has already dumped the last one. ring.At this time, it was the fifth lap of the sprint. Liu Huaxing's physical strength was still able to do well, but his breathing had already started to rush.

Under normal circumstances, jogging is to maintain the best state of breathing with only the nose, but this is in competition, so you must run two kilometers as fast as possible.So now Liu Huaxing also uses his mouth to breathe, but he still controls his breathing rhythm in an even state, without messing up, so that his body is still running at a normal rhythm.

But on the other hand, the few students who ran in the last few were already out of breath, and their movements were completely messed up. It was already difficult for the body to take in oxygen through breathing, and some of them wanted to give up.

But at this time, Liu Huaxing started to continue to speed up. Of course, he did not sprint as fast as a 50-meter sprint, but kept running as fast as possible under the condition that his body can bear. After all, he is now the first.Therefore, Liu Huaxing crossed the finish line with an absolute lead.

After crossing the finish line, he didn't stop in a hurry, but slowly slowed down and walked around again, letting his heartbeat slow down gradually, so as not to put too much load on the body.At this time, his breathing was actually not too fast, he adjusted it slightly and then calmed down. After all, he has run 20 kilometers, and these two kilometers are nothing at all.

After he finished a full lap, none of the others reached the end.

"Six points and fifty-seven." Li Ping gritted her teeth and gave him a hammer on his shoulder. "You stinky boy, not only are you good at sprints, but you are also good at long runs. Generally, eight minutes is a very good result. More than six points. How do you usually practice?"

"Four kilometers every morning, do some anaerobic training at night." Liu Huaxing replied simply.

When long-distance running is different from sprinting, the methods and effects of exercise are also different. Sprinting is an anaerobic exercise, while long-distance running is aerobic exercise.Anaerobic exercise builds muscles and aerobic exercise reduces fat. So long-distance runners usually have particularly developed leg muscles, but long-distance runners are tall and thin.This also shows that Liu Huaxing now has both endurance and explosiveness.

At this stage, Liu Huaxing can rely on physical fitness and technique to get good results in these two subjects, but in the field of professional athletes, basically no one can take both sprint and long-distance running at the same time.

"It seems that I have some understanding of fitness." Li Ping said, waved him to sit down: "Sit down, I will help you stretch your leg muscles, and you will continue to compete tomorrow. If you don't stretch, your muscles will be better. I can't stand the pain."
