Although the 100-meter dash is the simplest track and field event, there are many techniques when carefully studied, but the vast majority of the 100-meter dash skills are used by professional athletes. Pen, fun, pavilion www. biquge。 info

There are many ways to enhance the explosiveness of the lower limbs, but the core is nothing more than weight-bearing and increasing resistance, such as weight-bearing jumps, weight-bearing squats, pulling people to run, pulling tires to run, and so on.

As for speed training, it is nothing more than repeated running again and again, in order to avoid the impact of "speed barrier", you can also regularly use the competition training method for speed training, so that there is a comparison between athletes, which can stimulate the maximum speed of athletes.

Li Dai had already bought the equipment for training. For example, a weight-bearing sandbag tied to the leg, if you buy it online, you can buy a set for thirty or forty yuan, and it is also free shipping. Li Dai made a special trip to the sports goods mall and bought ten sets at a wholesale price, which is cheaper than buying from an e-commerce company. Then Li Dai bought some waste tires from the second-hand auto parts city, and hung a rope to use for resistance training, which was not worth a few dollars.

In this regard, Li Dai's experience may not be as good as those professional coaches, but the methods of training are not inferior to others.

……

During the lunch break, Li Dai fiddled with a set of leggings sandbags.

"The current gaiter sandbags are much better than the ones I used when I was a child, and I remember that the old sandbags were really filled with sand, and the sand could easily leak out of the cracks, and if it fell into the shoes, it would be very abrasive. Now the leggings sandbags are made of small steel balls and lead bars, and the materials are much more comfortable than before. Li Dai arranged a row of leggings neatly, and then looked at the experience points he had gained.

Although there were only 13 students, Li Dai gained 18 o'clock experience through this morning, which is the same experience as the previous training of 36 students in the physical education high school entrance examination tutorial class.

"With so many experience points, in the same time, there are only 13 students, but the effect is similar to the previous 36 students, which is equivalent to three times the experience." Li Dai was not only surprised, but also felt a little happy.

And the voice of the system immediately explained: "I told you a long time ago that different training objects have different experience points. The group of little fat people you trained before were not even as good as the 'five scumbags' in sports, so you will gain very little experience, but now these high school students you train are all stand-ins among their peers, and the experience points you gain will naturally increase, and it is normal for one to top the previous three. ”

"In this way, if there is really a world-class athlete who trains for me, my experience will not soar!" Li Dai has secretly made up his mind in his heart that if he has the opportunity, he must be a coach for professional athletes and be a real coach.

Li Dai took out the list of students, and the athletic ability value of each person on it, Li Dai had already detected it, and everyone's athletic ability value was above 65, and the highest one reached 71, which was already a very high number for a sixteen or seventeen-year-old sophomore. You must know that Li Dai's athletic ability value is only 80, but Li Dai is young at the peak of his body, and due to professional needs, Li Dai usually does more physical exercise, while the main energy of high school students must be focused on studying, and there is not much time spent on sports.

In the afternoon, Li Dai detected the students again, but everyone's athletic ability value remained the same, without any improvement, but Li Dai was not disappointed, the higher the athletic ability value, the more difficult it is to improve, which is something that Li Dai has already discovered.

"In the past, I trained some teenagers with an ability value of 20, so the progress was very obvious, but now I have to train young people with an ability value of more than 60, and the progress rate is much slower." Li Dai said secretly in his heart.

"It's not all." The voice of the golden avatar sounded, and continued: "At that time, you had the experience card of a first-class coach and could enjoy the training effect of a first-class coach, but now you are just a third-rate coach, and there is a huge gap between the first-class coach and the third-rate coach!" ”

"Upgrade, or upgrade faster." Li Dai sighed silently and focused on the training ground again.

……

At five o'clock in the afternoon, although the sun was still hanging high, the sun was still dazzling, and the air was still rolling in a heat wave, it was almost time to get out of school.

After a day of training, all the students were already exhausted. So Li Dai bought more than a dozen ice creams out of his own pocket, and one person was given one, and everyone sat together and began to rest.

After a hard day of training, everyone is in a state of fatigue, at this time sitting on the ground blowing the wind, holding a bottle of sweet mineral water in hand, and holding an ice cream in the mouth, no matter what the taste, but it is definitely a very pleasant thing.

Li Dai told them to rest for a while to regain some strength, while he himself sat by the door, looking at the end of the road, he waited. Soon after, a black Land Rover SUV appeared in Li Dai's sight.

"Here, it's Chen Haiyang's father." Li Dai turned his head and asked, "Chen Haiyang, how is your physical recovery?" ”

"It's okay, but my legs are still a little sore." Chen Haiyang replied.

"Warm up a little bit and prepare for the 100-meter test. Let your dad see the results of your training today. Li Dai said.

Chen Haiyang's father parked the car, opened the car door and walked down, Li Dai also happened to come over at this time, only to see Li Dai take out the electronic timer again, and then handed it to Chen Haiyang's father, and said; "It's a coincidence that you're here, I'm about to test Chen Haiyang, please give me another time, and just let you see the effect of my training today."

Chen Haiyang's father was thinking about leaving with his son, but as soon as Li Dai said this, he still took over the electronic timer, after all, his son was training here for a day, and he, the father, also wanted to know what the effect was.

When Chen Haiyang tested in the morning, he had not yet been included in the system's training list by Li Dai, but now Chen Haiyang has been added to the training list by Li Dai, which also means that Chen Haiyang has begun to enjoy the effect of "explosive aura".
