The importance of explosive power to the 100-meter dash is self-evident. Although Dai Li's explosive power aura can only increase his explosive power by 10%, for a sport that can be completed within ten seconds, the 10% increase in explosive power can already be regarded as an astronomical figure.
The aura of explosive power is a trick for Dai Li to retain his students. It is precisely because of the existence of this aura of explosive power that Dai Li will give the students a test before the morning training begins, and then record the results at that time; he will do it again after the evening training. Take a test and record the results. Comparing the results in the morning and evening can show the results of Dai Li's training in a day.
Although Dai Li doesn't know how much improvement this 10% increase in explosive power will ultimately show in speed, what Li Dai is sure of is that the improvement in performance brought about by the aura of explosive power can be very clearly reflected on the electronic timer. come out.
However, Chen Haiyang's father did not have high hopes, because he knew that physical training is the accumulation of time. There are no shortcuts in this regard, and it is impossible to achieve it in one or two days. It's only a month. I have only trained for one day, so there is no "training effect" at all.
"It's just a trick. It's just a day's training. What effect can it have? Is it possible that it can be half a second faster? This young coach probably wants to express himself too much and wants to retain his students. Since he uses this stupid trick, Isn't he worried that after a day of training and exerting so much physical strength, his performance may be lower than in the morning?" Chen Haiyang's father thought to himself.
Training will consume a lot of physical energy, and the results will not be as good as when the physical strength is full. Of course, Li Dai can imagine this, so Li Dai let the students take a half-hour rest. For high-level professional athletes, half an hour's rest is definitely not enough, but for beginners, half an hour's rest is enough for them to save the energy for a 100-meter sprint.
At this time, Chen Haiyang stood at the starting line again, and Chen Haiyang's father also stood at the finish line again, holding the stopwatch.
Dai Li pulled the trigger of the starting gun, and Chen Haiyang rushed out and quickly started to speed up.
"Why do I feel like my speed has become faster!" Chen Haiyang, who was running, could feel that his speed was faster than in the morning.
"1, 2, 3, 4..." Li Dai in the distance did not have a timer in his hand. He was counting silently in his heart. At this time, he also felt a little nervous and worried that Chen Haiyang's results would not be satisfactory. If so, there is a high probability that this student will not be retained.
"Whoosh!"
Chen Haiyang's father felt a figure flying past his eyes, and he immediately pressed the pause button on the electronic timer.
"I don't know what Haiyang's results will be this time." Chen Haiyang's father still had expectations for his son. He looked intently at the electronic timer in his hand, his expression suddenly solidified.
"How is this possible? 12 seconds 39, did I see it wrong?" Chen Haiyang's father blinked hard, and when he looked carefully, the electronic timer showed that it was indeed 12 seconds 39.
"When my son took the test before, his fastest time was never under 12.80 seconds. Now he actually ran 12.39 seconds, which is more than half a second faster than in the morning! Did I press the button too early?" Chen Haiyang's Dad recalled it carefully and confirmed that he did not wake up early.
"Is it possible that the electronic timer is broken? It's impossible. If the timer is broken, it will only slow down, not speed up." Chen Haiyang's father suddenly raised his head and looked at his son, I thought to myself: "Could it be that this is the progress he made in today's training?"
At this time, Dai Li had already walked over quickly, and he asked: "How are your grades?"
"12 seconds 39." Chen Haiyang's father replied honestly, with a sense of unconfidence in his words.
"I remember that in the morning, Chen Haiyang's time was 13.03 seconds, which was an improvement of 0.64 seconds. The effect of today's training was very good." Although such a large improvement was due to the aura of explosive power, Dai Li did not hesitate to He took the credit for himself, and then he continued: "I remember that the standard for national third-level athletes is 12.40 seconds by hand. Now Chen Haiyang has exceeded this data. If he takes part in the test now, he can also get a national third-level athlete." The certificate of a top athlete.”
The qualification certificate of the national third-level athlete basically has no effect. At most, it is an affirmation of personal ability. However, for ordinary beginners, the national third-level athlete is also a very inspiring achievement.
Chen Haiyang's father hesitated for a few seconds, and then suddenly said: "Coach Li, I want to let Haiyang test it again. Do you think it's okay?"
Dai Li paused slightly. He knew that Chen Haiyang's father didn't believe in this result and thought it was a coincidence, so he made this request. Dai Li would definitely not refuse it. He said, "No problem, but still Let Chen Haiyang rest for ten minutes first. Continuous testing can easily cause strain on the sexy lines and curves. I did the testing on several other students first."
Dai Li looked at the form in his hand and shouted towards the training ground: "Xu Qingliang, do some warm-up exercises and prepare for the test!"
Xu Qingliang came alone in the morning, and no parents came to pick him up after school in the afternoon, so Li Dai could only let him take the test by himself and tell his parents the results when he returned.
Xu Qingliang's figure rushed across the finish line. Li Dai pressed the electronic timer. He glanced at the number on it and said, "12 seconds 42, a good result. Your score in the morning was 13 seconds 10. Today's training , you have improved by 0.68 seconds! Don’t forget to tell your parents about your progress today when you go back.”
Immediately afterwards, Dai Li turned around and called another classmate's name: "Lu Congyan, it's your turn."
…
Chen Haiyang rested for ten minutes and then stood on the starting line again.
"Everyone, get ready..." Li Dai raised the starting gun, and with the sound of a gunshot, Chen Haiyang rushed out of the starting line again.
In the second test, Chen Haiyang was mentally relaxed a lot and his condition was better than before. However, it was only ten minutes since the first test and Chen Haiyang's physical strength had not fully recovered, so I ran a time of 12.51 seconds, which was 0.12 seconds slower than the first test.
Although the speed was slower than the first time, this still surprised Chen Haiyang's father. He ran unexpected results twice in a row. Chen Haiyang's father had to believe that Chen Haiyang really made a big improvement. improvement.
"Coach Li is really amazing at being able to improve his performance so much in one day! If I hadn't seen it with my own eyes, if I hadn't been timing it in person, I wouldn't have believed it!" Chen Haiyang's father looked at Dai Li with a different look. , Ten minutes ago, he thought that Dai Li was playing tricks, but now he knew that the coach Li in front of him was really capable.
"I think even the coaches at the sports school don't have such a good training level. The training effect is simply incredible. No wonder Coach Li dares to promise to refund money if he doesn't meet the standards. It turns out that there are really two brushes. Maybe it's true. The child should be handed over to Coach Li." Chen Haiyang's father thought of this and had already made a decision in his heart.
…
Dai Li waited for the last student to leave, packed up his things, and then locked the door of the warehouse.
"I don't know how many of these 13 students will be left in the end." Dai Li looked at the straight road in front of him, feeling a little confused.
"When we go back, call these parents to confirm!" Dai Li said to himself.
