Uma Musume: From Being Knocked Ten Meters Away

Chapter 320 Physical Strength Reserves ≠ Instantaneous Explosive Power
Yasui Shin was already somewhat stunned by Kita Genko's current appearance and posture. After spinning around twice, Kita Genko scratched his head, looked over expectantly, and grinned foolishly:
"If I could really take it with me... Trainer, do you think I could talk to the Emperor Guild Master and use this outfit as my final battle suit?"

Yasui Makoto snapped back to reality: "The final outfit...?"

“Yes,” nodded, and Northern Black Horse turned half a circle again, its gold ornaments jingling softly for a moment. “Because it looks good. Trainer, you also said it looks good, so it will definitely look good in a competition.”

"Well... you could try asking the emperor."

Yasui Makoto thought for a moment, then spread his hands and said, "I'm not very familiar with the final outfit either, but if you're really sure that this style can be used for the design, I can help you write the application or something."

"Okay! It's a deal then, Trainer!"

After nodding vigorously, Kita Genko happily turned around a few more times, then curiously looked around Yasui Makoto's room.

She quickly spotted the computer, notebooks, and papers in the living room, and gave them a reproachful look:
"As expected, he told me and Xiaoxingmu to go rest while he came here to work secretly... Honestly, trainers should also get some rest."

Yasui Makoto felt that there was nothing wrong with his work habits, and he was going to go to sleep after he finished his work anyway.

But upon hearing what Beifang Xuanju said, he felt inexplicably guilty.

"Ahem... I'm actually about to rest; I'm almost done with the initial debriefing."

After offering an explanation, he rubbed his nose, walked towards the computer, and casually asked, "What about you? Aren't you sleepy anymore? Or are you going to take another nap later?"

"Sleepy... I'm not really that sleepy."

His reproachful expression suddenly turned somewhat troubled. Kita Genko scratched his head, glanced at Yasui Makoto operating the computer, and then his expression changed:
"By the way, if you're busy for a little while, trainer... there's something I'd like to ask you."

"Okay, go ahead." Yasui Makoto nodded as he typed on the keyboard.

During his recovery period, due to the inconvenience of his arm, he actually handed over many of his tasks to Northern Xuanju.

While preparing for Arima Kinen, Kita Genko learned a lot about the work of trainers from him. He couldn't handle the more technical aspects, but he could handle the simpler ones.

He had gotten used to the girl watching him work and asking him questions or seeking his advice.

"It just so happens to be today's practice match."

Northern Genko was also used to this kind of interaction. She naturally sat down on the sofa next to Yasui Makoto, and after thinking for a moment, she sat down cross-legged on it.

Her hands unconsciously gripped her pale ankles. She tilted her head, pondering:
"It's just that... you told me that physical reserves are not the same as instant explosive power, so a lot of our previous training has been focused on this direction."

"However, it must be a problem with the venue; I felt it particularly clearly today."

"It was during the final sprint that I clearly felt I still had enough energy, but no matter what I did, I couldn't catch up with my classmates from California."

"Trainer, have you analyzed this part?"

When she asked the question, she looked at Yasui Makoto, then at the computer and a pile of papers on the table.

Upon hearing that the question was about his profession, Yasui Makoto immediately perked up.

He casually picked up a few sheets of paper filled with data and handwriting, glanced at them, and handed them to Beifang Xuanju, pondering:

"The feeling is more pronounced on mud tracks... which is normal, because the resistance is greater than on grass, so many sensations on grass are amplified subjectively, making them more noticeable."

"For example, in terms of pushing off the ground, my initial estimate is that in today's practice match, each step will consume 15% to 20% more lower body strength than on grass."

"This leads to excessive use of fast-twitch muscle fibers in the early stages of catching up, especially during the initial positioning phase, in order to maintain stride length, resulting in more neural fatigue. Then, in the later stages, although your slow-twitch muscle fiber advantage still exists, the nerves become fatigued, causing a decrease in the efficiency of muscle recruitment, resulting in a 'mechanical break.'"

As Yasui Makoto explained, Kita Genko kept flipping through the papers in his hand.

Seeing that the explanation was coming to an end, she looked up, seemingly lost in thought, and said:

"The muscle tremor rate in the weighted leg is 0.3 Hz faster than before the curve... the ankle flexion angle exceeds 85 degrees..."

She muttered a couple of things to herself, then looked at Yasui Makoto:
"So, I feel like my feet are glued to the ground, and I have enough strength but can't lift my feet or increase speed. Besides muscle and nerve issues, there are also problems with rhythm and running form?"

Yasui Makoto was well aware that the data he was muttering about was not really understood by Kita Genko.

Because that's a highly specialized part, requiring additional data for analysis, which even some trainers might not know how to use, it would certainly be more difficult for a female racehorse still in service.

However, the Northern Black Horse's feeling was correct.

"Well, to put it simply, although you adjusted your rhythm and running form in time during the race, you were still still using grass as a habit."

"It's impossible to adjust this in just a few minutes of a game, so you definitely have a problem with this aspect."

"But only on muddy ground."

After explaining, Yasui thought for a moment and then returned to the previous topic:
"So, if we don't talk about the muddy part and just talk about the instantaneous explosive power, there's another issue: in the last 200 meters or so, you were managing your breathing too fast."

"Too fast...?"

Northern Black Horse recalled for a moment, then frowned: "I feel... it should be alright...?"

"Judging from the breathing rhythm alone, it's actually not bad."

As he spoke, Yasui Makoto opened a software program on his computer and displayed several graphs:
"It's not certain if we can connect it to the 'mechanical fault' section."

"The current preliminary calculation results show that your breathing rate increased by about 36% after 200 meters. This increase is too large, so it leads to 'accumulated oxygen debt'."

"In other words, your internal circulation hasn't had time to adapt before you increase the oxygen supply. It may seem like the supply is sufficient, but in reality, it's completely unable to match the nutritional needs of the muscles."

"This is the direct reason why you feel that 'the more you try to speed up, the slower you can move,' and you may even experience some oxygen deficiency."

After speaking, seeing a look of recollection on Kita Genko's face, Yasui quickly realized that she was thinking about the corresponding feelings during the competition. He couldn't help but smile and continued:
"Besides these internal reasons, there are also external factors."

"For example, mud is much softer than grass and is more easily damaged."

Simply put, the surface hardness of a dirt track is more prone to localized softening.

"I'm not entirely sure about the exact figures, but I'm certain that the court had already been trodden on multiple times before your match against the California Shining, so it was already quite soft."

"Your race consisted of two laps, and the second half was closer to the intensity of a real race, which made the final straight line softer."

"So according to my estimate, the last 100 meters or so of the track is very likely to have an energy absorption zone."

"This makes the efficiency of the reaction transmission when you push off the ground much lower than in the early and middle stages, and the propulsion speed will naturally decrease."

"That is, as you said, the external reasons why you want to accelerate but can't increase the speed, or even stall."
