……

In a villa with a pool in Kingston, Jamaica, Asafarville was lying on a lounger by the pool, looking at the crowd busy in the room, his face full of helplessness.

It cost him a lot of money to decorate this villa, although his requirements for the living environment are not particularly high, and most of the prize money and advertising endorsements of the competition are spent on modified cars, but driving his own home for surgery still makes him feel a little distressed.

"Well, the steps have been removed and replaced with soft rubber aisles."

Dole, the agent, walked out of the room and glanced at Asafavil with a complicated look on his face.

"Thank you, Dole." Asafavir rested his left foot on a stool, his face slightly solemn, and his eyes seemed to have a faint look of anxiety.

"Asafa, you have to be more careful in the future." Dole looked at Asafavil and shook his head helplessly.

On September 30 last year, Asafavir won the men's 200m in his last super track and field event in Yokohama, Japan, but suffered a ligament injury in his left leg.

After a few months of rest, he recovered from injury, and his personal condition was adjusted to his best, preparing to go to Sydney in February to participate in the Sydney Grand Prix.

As a result, a few hours before the plane, Asafavir tripped and fell on the steps of his home, and received four stitches in his left knee in a row.

In this way, the situation of parents tripping and falling is actually very common in ordinary people's lives, and Asafavir did not show any special performance for a period of time at first.

But when news came yesterday of the men's 60m at the Indoor Athletics Championships, Asafavier uncharacteristically contacted him and asked to change the steps in his home to a soft rubber aisle so that there would be no more trips.

"I'll take notice, Doler." Although Asafavir's face was calm, his heart was actually more anxious than anyone else.

It's already March, the Olympics are getting closer, and he's injured again, and although he's recovered now, it will take a long time to get his body to the top of his body if he lacks training for a long time.

He has actually considered participating in the Indoor Athletics Championships this year, and the original plan was to travel to Valencia, Spain, after the Sydney Grand Prix in February, to get back to his form as quickly as possible.

As a result, the February injury made all of this to naught.

During this time, he did the most training, swimming, and he could only maintain his condition in this way, but even so, without systematic sprint preparation, he was not sure whether he would still be able to run his best, and in the second half of the year, he would have to face the challenge of Yechin and Jason Gaby.

……

Arkansas, USA.

In an indoor training hall, Jon Drummond and Lance Brauman were standing on the sidelines of the field watching a figure that quickly skimmed the track, and after the figure sprinted off the starting line, both coaches turned their attention to the timekeeping and camera equipment on the sidelines.

"There has been a noticeable improvement in the start, but Jason's acceleration from the first 10 to 20 metres is still not particularly advantageous." Jon Drummond frowned slightly, walked to the side and looked at the starting footage captured by the slow-motion camera, and said to Lance Brauman beside him.

"There is nothing left to correct in the starting motion." Lance Blauman followed along to watch the footage inside the camera, frame by frame in slow motion, showing all of Jason Gaby's movements clearly and unmistakably in front of the two.

"Jon, you turn on the slow shot of the 100-meter start of Asafavir and Yechin, and let's make a set of comparisons." Lance Brauman suddenly spoke to Jon Drummond after watching Jason Gaby's recorded video for a while.

"Okay." Jon Drummond neatly slowed down the start of the 100m video of Asafavir and Yechin, comparing the two with the footage Jason Gaby had just recorded.

"Do you see that, Jon?" Lance Brauman pointed to a shot in the video and continued, "The explosive start that Asafavir and Yechin took, in the first three or four steps of the start, the ball of the foot and the ground were very full, almost the entire ball of the foot, while Jason only had the first half of the foot.

In this way, although Jason reduces the contact time between the soles of his feet and the ground, which seems to be advantageous, after running three or four steps, we can see that sufficient contact with the ground contact area can make the legs stay in the air longer and be able to move longer in the air.

The first two or three steps of the start may be a little slower than Jason Gaby, but at around 10 metres you can gain a clear advantage.

Moreover, Jason's pendulum start, the time of the left and right foot kicks, allowed him to get enough forward propulsion, but at the same time, the angle of inclination also sacrificed a certain amount of forward propulsion. ”

"Yes, that's a certain amount of time sacrificed for Jason in the first half." Jon Drummond nodded, although he had not been mentoring Jason Gaby for a long time, but he had been for more than a year, and he was still very clear about Jason Gaby's technical characteristics.

However, this is not the biggest problem, after all, whether it is the men's 100m or the men's 200m, in fact, athletes need a stage of accumulation and acceleration.

Charging a little slower at the start can leave enough physical strength to add up to the speed in the middle and second half of the race, which is the way that many sprinters choose.

Many of the top sprinters don't suddenly get to the top of their speed after the start, but have a little bit of reservations. This kind of reservation is not the kind of reservation that releases water, but gives the body more full acceleration, so that the body can increase the absolute speed to the highest speed when entering the highest point of speed, so that when the final crossing of the finish line is over, the natural performance will be better.

"The biggest problem is that this way of running, for Jason, the burden on the body is very heavy." Lance Brauman saw that Jon Drummond agreed with him, and continued.

Jason Gaby broke out in the second half of 2006 and became the world's top sprinter in the 100m in 2007, in which Jon Drummond gave a lot of starting guidance, but the bigger problem is the physical burden of this starting style on Jason Gaby.

"Coach, Jon, I just ran like this?"

As the two were discussing and talking, Jason Gaby walked over from the other side and asked the two of them.

"Jason, it's the Olympics this year, I know you're in a hurry, but I want you to slow down, you can't get hurt, if you get hurt that's the biggest regret." Lance Brauman said as he looked at Jason Gaby as he walked over.

"But coach, my opponent is growing too fast." Jason Gaby shook his head, having received the news of his victory in the men's 60m Yechin at this year's World Indoor Championships.

The result of 6.42 seconds was a little hard to believe when he saw it. He was very familiar with Ye Qin's technical characteristics, and he started slower than him in the first half of the race, but he actually ran 6.42 seconds in the 60-meter race, which had to make him feel the pressure.

Jason Gaby's current best time in the 60m is 6.55 seconds at the Tyson Invitational, the annual indoor track and field event at the Randall Tyson Athletics Center on February 11, 2005.

At that time, Jason Gaby was certainly not as good as he is now, but even if he improved his start and improved his personal ability, he is not sure that he will be able to run under 6.50 seconds.

Sprinters are good at the first half and good at the second half, and these two different characteristics make them show great strength in different events.

"Jason, you are a professional athlete, I can understand your desire for the Olympic champion, and I know how unwilling you are to lose to Ye Qin in the men's 100m and 200m last year, but you have to understand that you only need to do it first if you stand on the track of the Yanjing Olympics in full condition, otherwise, once you are injured, all your expectations can only be empty words."

Jason Gaby looked at Lance Blauman, and then at Jon Drummond next to him, and after a long time, he breathed a sigh of relief and a smile appeared on his face, "It's me who pushed myself too hard." Thank you, Coach! Thank you, Jon! ”

"It's okay, Jason!" Jon Drummond smiled and waved his hand, "Go home, Jason, it's okay to spend time with your daughter, you need to stay with your family and kids, we won't start the season until May, what is needed now is rest and adjustment." ”
