Increasingly debilitating leg
It is often said, the older, the more debilitating leg. But scientists have found that with the progress of human civilization, human beings are becoming increasingly weak legs. The decrease in the function of the human, the drop of leg strength is greatest. Now our leg strength than 4000 years ago, the average level has dropped by 54%, which we deal with the continuing decline in average physical primary responsibility.
Although there are a variety of modern sport, but still can not make up the pressure to survive, heavy physical labor, a significant reduction in military operations against the lower leg strength requirements. In human history, we often need to run fast to catch up to avoid the beast, or catch their prey, make every effort to pull the wagon filled with stones, weight fast marching for several days, and now these cars are comfortable, high-speed Elevator, heavy goods vehicles instead.
Scientists have warned: if we do not systematically improve their leg strength, one day humanity will face either can not move heavy objects, can not move themselves, can only rely on machines to achieve their minds all the envisaged situation, then we their health will be seriously threatened.
Legs - a source of strength
History of human civilization is one of the load gradually transferred from the body to the machine's history, it is destined to the body's own source of strength - legs, exercise less and less experienced. Leg strength accounted for more than 90% of human strength, a person's strength depends on the size of his leg strength. It was once the main form of heavy manual labor - carrying stones, carrying a heavy weight-bearing walking and pulling four cars are mainly rely on leg strength. Studies have shown that the decline in the human upper body strength is minimal, and the rapid decline in leg strength, it fully reflects this.
While we need to fight against heavy fewer opportunities, but for those power projects, it means that athletes increasingly difficult to get good grades. Clean and jerk, snatch world record created 20 years ago, and squats, leg press world record created 60 years ago, has fully demonstrated this point. The strength of the world's oldest clubs - Gladiator's coach Henry Milanitusky said, compared with 50 years ago, the overall level of leg strength athletes declined, because I like power projects fewer and fewer people to start exercising time is getting late, despite a substantial increase in training techniques, they are just barely able to maintain the overall competitive level will not drop.
Leg strength - physical beacon
Many people narrow understanding of the power of strength and ultimate strength will be confused. Leg strength is not just about the ability to squat weight limit, your speed, power, endurance, depends on leg strength, and is a direct reflection of leg strength. Upper body strength of course very important, but compared to the upper body strength and leg strength is limited, not enough to affect the overall situation, and people are walking upright animals, people almost every action has an active participation in the legs, which determines the scope of leg strength than upper body strength wide.
In the simplest running, jumping, for example, they are in fact all depends on the relative strength of your legs, which limits your leg strength and weight ratio, which is lightweight lifters requirements are actually the same, so lightweight weightlifting athletes running, jumping ability are strong, and vice versa. Without a strong running, jumping ability, you in almost all ball games are very difficult to make a difference.
Fighting the project, too, various heavy blow and surrender technology, will depend on the dominant leg force. A heavy chain of the firing force, the leg strength both the starting point of this chain is the most important part of the above. Vigorously hitting situation is the same. Boxing, wrestling, baseball, volleyball, these look very different sports, there is one thing in common - all require strong leg strength.
Even in apparently associated with less leg movement, it is also still in effect. In the six individual gymnastics, there are two - floor exercise and vault, depending on leg strength, while the remaining four of logic, also depends on the leg strength. Modern bench press technique attaches great importance to the leg force, athletes rely vigorously stomp and arch their backs to provide additional impetus for the barbell. Even in the most "arm" of the movement - pull the wrist, leg strength body force participation than rely solely on the forearms and biceps force much more effective.
The above three examples in the world of sports is almost the only three leg strength backseat example. In all other sports, leg strength are dominant.
Leg strength - an indicator of health
Squat and riding a stationary bike from a very early start, it was as a measure of heart health. When the doctor would simply evaluate the health of a person, he would go to observe the legs, rather than the upper body. The reason is simple, a person's athletic ability depends mainly on the legs, weakness of the legs will make people gradually lose the ability to exercise, health, it is difficult to maintain. On the other hand, respiratory, circulatory system also depends on the leg strength exercise. Because of the above-dominant form of exercise load is too small workout area is also very limited, insufficient to achieve the ability to improve the strength of the internal organs. For example, the squat bench press training power is four times the curl of 10 times.
We even can also be seen from the figure on the health of a person. Medical research shows that stout legs are healthy in most cases reflect, but also to promote health. The thick upper body, tiny legs is unhealthy performance, because a reasonable exercise will not happen. The most typical unhealthy body than upper body stout, bucket, like tiny waist and lower extremities.
