Although Li Dai was complaining, he was quite satisfied with this reward item in his heart. The Athlete Patch is an item reward that can cause fundamental qualitative changes. Although the cost of 10,000 experience points is a bit high, it can bring value for money.
After a brief surprise, Li Dai placed the athlete's patch on it, which looked like another reward item.
This thing is familiar to anyone who has been to elementary school. It is a book cover, which is what primary school students use to pack textbooks. However, there are no patterns on it, only the words "upgrade".
"Book cover? Upgrade?" Dai Li didn't understand what it was.
"You should read it backwards. This is called an upgrade book cover." The system continued: "Remember those skill books you obtained before? This upgrade book cover is used to upgrade the skill books. Put this book cover on the skill books , the corresponding skills will be upgraded, and the effect of the skills will be greatly improved."
"Can it be reused?" Dai Li asked immediately.
"No, this is also a one-time consumable item, so before using it, you must carefully consider which skill you want to upgrade." The system said solemnly.
"Then can you tell me first, the effect of the skill upgrade?" Li Dai asked tentatively.
"The effect of skill upgrade is somewhat random. I can't give you an exact answer." The system replied.
"Are you betting on luck again?" Dai Li frowned slightly, and then started to think.
At present, the skill books owned by Dai Li include weight loss exercises, fat reduction exercises, relaxing massage, rehabilitation massage, flexibility yoga, warm-up square dance and physical runaway. The morale-boosting book is in the form of a page, not a skill book. The form exists, so the upgraded book cover cannot be used.
What Li Dai has to do now is to choose one of the seven skill books including weight loss exercises and upgrade it.
"The effects of weight-loss exercises and fat-loss exercises are similar, but the proportion of athletes who need to lose weight is only a small number, so these two skills can only be regarded as niche skills and there is no need to upgrade them." Li Daixian denied the weight-loss exercises and fat loss exercises.
"Although flexibility yoga can quickly improve the flexibility of the body and enhance body coordination, physical fitness can also improve the coordination of the body to a certain extent. The improvement of physical fitness is far less than that of flexibility yoga, but physical fitness can also be improved In other aspects such as endurance and strength, from this point of view, the comprehensive benefits of physical fitness are obviously better than flexibility yoga." Li Dai also denied that flexibility is getting better.
"For warm-up square dance, only the warm-up item can be used. The practicality is relatively simple, and the form of square dance seems a bit too ugly, which may cause people's criticism." The fourth thing Li Dai denied was the warm-up. Square dance.
"Compared with relaxing massage and rehabilitative massage, rehabilitative massage is definitely more important. I have been a coach for so long. Whether in the national team, the provincial team, or the Dingtian Club, I will encounter injured athletes. , From a training perspective, athletes’ injuries are inevitable, so the practicality of rehabilitation massage is very strong, second only to physical fitness.”
Thinking of this, Dai Li decided to choose one of the two programs of rehabilitation massage and physical fitness to upgrade.
Comparing the two, physical fitness can be used on all athletes, while rehabilitation massage can only be used on injured athletes. Physical fitness obviously targets a wider group of people.
But rehabilitative massage is a skill that can create miracles. Since Dai Li acquired this skill, it has helped many athletes reduce their injuries. More importantly, through the rapid recovery from injuries, Dai Li has established a relationship with the athletes. a bridge of trust.
"It's a bit difficult to choose!" Li Dai even planned to flip a coin and see the heads and tails to decide.
"Let's use rehabilitation massage. Although the use of physical strength training is more widespread, it is basically an improvement in ability level. However, rehabilitation massage can make a person regain hope... "
Dai Li couldn't help but recall Lin Feixiang. He gave up on himself because of his injury, and then returned to the game because of his recovery. It can be said that rehabilitation massage gave him a new life.
Thinking of this, Li Dai put the upgraded book cover on the rehabilitation massage skill book. He preferred the pleasure of creating miracles.
After a golden flash, the cover of the Rehabilitation Massage Skills Book also changed, with a solid border added. Dai Li immediately started reading the new Rehabilitation Massage Skills Book, but found that the content was unchanged from before.
"The massage techniques are still the same as before, without any changes. So the upgrade of the skill book is just a simple improvement in effect?" Li Dai asked.
At this time, the system slowly explained: "The effect of rehabilitation massage has indeed improved compared to before, and the current rehabilitation massage will have the function of activating damaged nerve tissue and promoting the regeneration of nerve cells."
"What do you mean?" Li Dai asked immediately.
The system immediately explained: "You should know that the recovery speed and effect will be different depending on the injured part of the athlete. And the most difficult to recover is undoubtedly nerve damage. Many nerve injuries are irreversible. Once Once injured, there is no way to recover. This new effect of rehabilitation massage can solve this problem to a certain extent. Of course, the final effect will vary from person to person."
Dai Li recalled the knowledge in his mind, and then nodded as if he was suddenly enlightened.
Different muscles and tissue cells in the human body recover differently after damage. For example, the cells on the lips are the most active cells in the human body. They die and regenerate in large numbers every day, so wounds on the lips heal very quickly and leave no scars.
For another example, skin injuries heal more easily than muscle or bone injuries. After the skin epidermis is injured, within 24 hours of the trauma, the basal cells at the edge of the wound begin to proliferate and migrate toward the center of the wound under the clot, forming a single layer of epithelium covering the surface of the granulation tissue. So if the skin is scratched, it will heal quickly on its own.
Injuries involving deep muscles require suturing to heal, while torn ligaments and fractures require surgery. Moreover, the recovery time for this type of injury will be relatively long. It takes a hundred days to break the muscles and bones. For example, many key parts were injured, such as torn menisci and severe fractures of ankle bones. It may even take a year to recover as before.
In contrast, if the nerve tissue is damaged, recovery is not only a matter of time, but in many cases, whether it can even be recovered is a question.
For most tissues or organs in the human body, physiological recovery is equivalent to functional recovery. For example, if you have a broken finger and cannot hold chopsticks, you will have physical and functional problems at this time. Once the finger injury is healed, I can naturally hold chopsticks, and my physiology and functions have recovered.
This does not apply to nerve injuries. After nerve damage, physiological recovery is not the same as functional recovery. For example, those who have injured their spinal nerves will have their lower limbs affected and may even be unable to stand up for the rest of their lives. Even if their spinal nerves recover, they still cannot stand up. This means that they are better physically but still have no functional function. recover.
The new effect of rehabilitation massage, which activates damaged nerve tissue and promotes nerve cell regeneration, is obviously specifically targeted at this kind of nerve damage. This sounds very noble.
However, after Dai Li analyzed it carefully, his expression became depressed.
"For athletes, if nerve damage occurs, it must be a very serious unconventional injury. Since it is unconventional, the probability of occurrence is not very high. It may not be possible to encounter an athlete with nerve damage for several years. In the end, At least I have been a coach for so many years, but I have never encountered such an athlete. Therefore, this new effect of rehabilitation massage seems to be very incredible, but there are not many opportunities for real application."
Dai Li sighed with regret: "If I had known this, this skill upgrade should have been reserved for physical violence!"
