Many athletes will pursue a lower body fat rate. For example, the world's top track and field sprinters can even control their body fat rate below 8%. Another example is basketball, a sport that requires physical confrontation. Increasing muscles can help improve the body's ability to resist.
However, not all sports require a low body fat percentage. Just like skiing, if the fat content in the body is too low, it will not be conducive to keeping athletes warm, and too low a body temperature will inevitably reduce cell activity and slow down the operation of organs. Slow down, thus affecting the athletes' competition status. Therefore, there are almost no athletes with strong muscles among skiers.
For example, some water sports also require athletes to have a certain amount of fat in their bodies, because while fat increases body volume, it also increases the body's buoyancy, which allows athletes to spend less energy to maintain buoyancy. It's like water polo. If you put a muscle stick on the field, it will sink to the bottom and it will take a lot of effort to surface.
The body of a diver also needs a certain amount of fat, because if the body fat rate is too low, the muscles will be very stiff, the coordination of the body will be reduced, and it will be difficult to make complex movements. At the same time, the body will be impacted when falling into the water. , fat in the body can protect organs such as the liver. Therefore, although the muscles of divers are relatively developed, they are definitely not like bodybuilders.
In addition, as a racing sport, swimming athletes’ bodies also need fat. This principle is similar to that of water polo. Fat can provide buoyancy. People with a low body fat rate have to spend more energy to maintain body fat. The buoyancy used to move forward will reduce the physical strength, thus affecting the swimming speed. It is for this reason that there are no world champions in swimming among those black athletes with huge muscles, and many world champions in swimming events may not even have obvious abdominal muscles due to their body fat percentage.
The system continued: "Weight-loss exercises and fat-reduction exercises are two completely different things. Athletes in some events do not need a too low body fat percentage, so they use weight-loss exercises to reduce weight more quickly; while athletes in some events The lower the body fat rate, the better, so they need fat-reducing exercises, which can significantly reduce fat and reduce muscle to a small extent."
"I understand what you are saying, but in fact, how can there be so many athletes who need to lose weight? I am lucky enough to meet Yu Feifei. I am afraid it will be difficult for me to meet another athlete like this. "Yu Feifei gained weight because of her physical growth. Under normal circumstances, athletes maintain a lot of exercise every day and it is difficult to gain weight." Li Dai said a little discouraged.
Later, Li Dai set his sights on the second book.
"The last book was a cheating exercise for fat loss. I hope this one won't cheat me." Dai Li looked carefully. There were four big words written on the book: Relaxing Massage.
"Relaxing massage? It sounds like a great health care." Dai Li thought evilly in his heart.
"People will experience muscle soreness after a lot of physical exercise. This soreness will reach its peak within 24 to 72 hours after exercise. The soreness will basically disappear after 5 to 7 days. In addition to soreness, muscle pain will also occur. Stiffness, in mild cases, only tenderness, in severe cases, muscle swelling, hindering activities, etc. This is medically known as 'delayed onset muscle soreness'. If you perform extreme exercise in the summer, dehydration and low calcium may also occur. , low protein and other symptoms..." the system explained.
Dai Li immediately answered: "I know all this. The main reasons for muscle soreness are: first, the sharp increase in muscle tension and elasticity, or physical damage to the structural components of the head; second, the increase in metabolism, metabolism The toxicity of waste to tissues increases; third, the neuroregulation of muscles changes, causing muscle spasms and pain. I have learned all of these!"
“So you should know that massage after exercise can reflexively improve and regulate the function of the central nervous system and eliminate muscle fatigue. The anaerobic metabolites accumulated in the muscles during exercise can be transformed or excreted as quickly as possible through massage. .This relaxing massage does just that.”
The system's voice paused and then continued; "In addition, for athletes, relaxing massage can also help reduce the pressure on muscles and ligaments, prevent muscle strain injuries, and avoid muscle and ligament strains."
Athletes have to perform high-intensity training every day, so their muscles are often in a state of tension. Muscle tension can easily cause damage, just like a bow. If the bowstring is fully drawn for a long time, the bow will lose its elasticity over time. , or even be pulled off.
The same is true for the human body. If you maintain high-intensity exercise, you will be easily injured. Therefore, the more intense the training, the more auxiliary means are needed to relieve muscle fatigue. Compared with some expensive equipment, massage is obviously a better choice. A very simple and effective way. Many training teams will be equipped with professional masseurs and massage therapists. For example, some professional teams will also be equipped with pedicurists and acupuncturists to help athletes relieve muscle fatigue.
What the system introduced were all professional contents that Dai Li had learned, which made Dai Li feel a little drowsy.
"Okay, okay, I understand what you said!" Dai Li yawned, but suddenly, Dai Li felt that he seemed to have missed something.
"You seem to talk a bit too much today, and you just said 'for athletes'. Is there anything else you haven't told me?" Dai Li asked suddenly.
"I haven't had time to say it yet. This relaxing massage is effective for anyone." The system explained.
"Anyone? Does that mean ordinary people can use it?" Dai Li asked immediately.
"Yes, it is not just professional athletes. Relaxation massage is also effective for ordinary people or amateur athletes. The previous fat-reducing exercise, like the weight-loss exercise, is only effective for athletes." The system continued.
"If it can be useful to ordinary people, relaxing massage is much more useful than fat loss exercises." Dai Li finally felt a little happier.
"Actually, I don't think there is any difference. You are already a second-rate coach, so you can't be idle and give relaxing massages to ordinary people." The system interjected.
Dai Li was slightly stunned, and felt that this was true. The Dai Li now was no longer the Dai Li a year ago. A year ago, Dai Li only faced some junior high school students taking the high school entrance examination. But now, Dai Li is even in the world. The champion has also given guidance, so naturally he will not be idle and give relaxing massages to ordinary people.
"Calculating it this way, the usefulness of relaxing massage is not as great as I imagined." Dai Li thought to himself.
