But strength is relative. In modern society, people's physical quality is declining year by year. With a little muscle strength, they will stand out from the crowd, even those who are underweight. You can think that he is strong, which is relative.
And "weakness" is reflected in the body shape. For people with a certain muscle mass (beyond the average person) but low body fat rate, they usually look weak because they are covered by clothes.
So, this is a conceptual problem. Two people who look big and weak can only judge whether they are really strong when they compete for muscle strength. You will see big and fat people, weak and strong people and so on.
In fact, no matter whether you are strong or not, as long as you are healthy, it is the best. Pursuing a healthier and more reasonable diet and rest on the basis of health, and pursuing greater muscle strength in fitness is strength!
There is often a scene in movies where a burly black man sees a thin Asian with a contemptuous smile on his face, but he is beaten up. Obviously, thinness and weakness are not completely inversely proportional.
In real life, people also think that emaciation equals weakness, although you are muscular. Therefore, it is natural to be beaten.
Next, let's look at the relationship between muscle and strength.
First of all, what is muscle strength related to? Mainly two points: 1, the shape of the muscle itself, including cross-sectional area and length. 2. Neurocontrol factors.
What is a neural control factor? We can understand it as the conductor of muscle. In order to exert muscle strength, besides the quality of the muscle itself, whether the command and control is effective is also very important. This is like the combat effectiveness of an army, and we can't just look at combatants and weapons and equipment.
Neurocontrol factors mainly include the following points: 1, recruiting more sports units and recruiting synchronously. The exercise unit can be simply understood as dozens or hundreds of muscle fibers. Muscle consists of a large bundle of muscle fibers. When doing movements, not all muscle fibers are often activated to participate in the force. The more muscle fibers are activated, the greater the strength. Although some people are muscular, many muscle fibers are not activated during action, so the force generated is small.
Synchronous recruitment of muscle fibers is also very important. Synchronous recruitment means that many muscle fibers can be activated and contracted at the same time, so that the force emitted at that moment is even greater. However, this view is currently controversial.
2. Increase unit frequency coding. This may not be easy to understand. Let's assume that a motor nerve controls 1 bundle of muscle fibers, a wire is connected to the nerve, and a button is connected. When you press it, the nerves get excited, and this bundle of muscle fibers contracts, but the contraction range is not large. If you press it three times, this bundle of muscle fibers will continue to contract for a period of time, and the contraction range will be even greater.
However, if you keep pressing fast and send out a series of high-frequency electrical stimulation, the muscle fibers will keep contracting and reach the maximum contraction range. This contraction is called "tension contraction", when muscles exert the greatest strength.
When the frequency code increases, it is equivalent to keeping the brain pressing that button while doing the action, and the muscle strength will also increase. Resistance movement, especially fast resistance movement, is more effective in coding stimulation frequency.
3. Spontaneous inhibition is weakened. Spontaneous inhibition of muscles means that our muscles will limit their maximum strength by themselves. This is a bit like some cars that need to install a speed limiter to increase the speed to a certain extent. Even if the engine still has the ability to speed up, it should automatically limit the speed to this level.
Muscle contraction force can not be unlimited, muscle has strength, tendon or muscle internal tissue can not stand it. The tension they can withstand is limited, and even stronger they may be damaged. Muscle In order to prevent this from happening, there is also a speed limiter called Gorky Tendon Apparatus.
Golgi tendinous apparatus, also called tendon spindle, is located at the junction of muscle and tendon. This thing can feel the tension of muscle fibers. When the tension reaches a certain threshold, the motor neurons that dominate the contraction will be automatically inhibited and the muscles will stop contracting. At the same time, antagonistic muscles may contract to protect muscle tissue.
Some studies believe that through some targeted training, the tendon spindle can be desensitized, which is equivalent to closing or lowering the muscle strength limiter, and it can also make people exert greater strength. We often see news reports that an old lady rescued her belongings in a fire and walked as fast as flying with a big box of 80 kilograms ... Such reports may have exaggerated elements, but it is not impossible. Strong nerve pressure may temporarily close the tenon spindle and make people exert extraordinary strength.
To sum up, although people stubbornly believe that muscle development means weakness. This concept is not completely correct, and there are too many examples to prove it in reality.
thank you
It is difficult to gain muscle. Don't worry about becoming a muscle monster like Schwarzenegger, because you can't do it!
If you don't make a diet plan and eat hard, you will only become a big fat man!
For natural fitness, if the body fat rate is reduced to about 10%, even if you exercise for many years, you will only look like a slightly muscular man when you put on clothes.
Trust me, that's right.
This means to dress thin, take off your clothes and have meat.
