Why do my legs tremble when I land on the ball of my forefoot?

Because you don't exercise much, when the forefoot hits the ground, the calf needs to support the weight of the body in that posture, and it needs the coordination of multiple muscles, if you don't exercise much, the muscles will be very tense, and tremors will occur.

If you still don't pay attention to exercise, it is conceivable that you will have a hard time going up and down the stairs when you are 50 years old, and you will even fall. By the time you're 60, you'll probably not be able to walk.

In addition, there is this kind of Ya will affect the feeling of driving on the accelerator and brake, obviously feel that the foot joints are not strong, and even the calves tremble when they step on the brakes, and even if the muscles are out of control, they suddenly step on the accelerator or brake deeply, which is really dangerous. Recovery exercises begin with squat exercises.

That's because the force on the soles of the feet is uneven, which causes the leg muscles to tremble, so the legs will tremble.

It could be a stretch of the muscles of the legs.

It may also be due to trauma.

It is usually traumatic.

The forefoot on the ground and the leg can't help shaking, that is, you put your whole foot on the ground, don't put half of it, and see if it's okay?

1. Poor circulation in the feet

When standing, the leg muscles need to contract continuously to support the weight of the body. Standing for a long time can easily hinder blood return and circulation, causing blood to accumulate in the lower limbs, causing numbness and tingling in the feet.

Foot massage or knee height on a high chair for a while can improve blood circulation in the feet.

2. Muscle fatigue

Standing for too long makes the muscles easily fatigued, causing the feet to tremble. Muscle fatigue is caused by muscle soreness and lack of oxygen** caused by standing or walking for long periods of time.

Relief method: Fatigue and soreness can be relieved by changing feet while standing, walking, and performing local muscle massage.

3. Nervousness and anxiety

Psychological factors are also one of the reasons for standing feet shaking. When faced with a stressful or anxious event or situation, the increased hormone secretion in the body may cause excessive contraction of the muscles and skin bumps, resulting in muscle tremors.

Relief method: Psychologically, you can relieve tension by calming your breathing and listening to the relaxation. At the same time, it is also important to pay attention to rest and sleep time to maintain a balanced mentality.

4. Neurological disorders

Some people may experience muscle tremors when standing due to neurological problems. Often, this symptom is due to muscle tremors caused by a disorder of the central nervous system.

If foot tremors occur frequently, you should go to the hospital for examination in time to detect and ** neurological disorders as soon as possible.

It can be simply understood as the conditioned reflex of the human body. But it doesn't feel right to me that way.

It seems to make more sense to explain it in terms of "balance of forces". First of all, it is normal for people to sit with their feet flat on the ground. The points of action used to support the balance of the lower limbs are mainly concentrated in the heel and forefoot (the arch of the foot is not forced).

When the heel is lifted and only the toes are left on the ground, this relatively stable force structure is broken. At this time, your lower limbs are mainly subjected to forces from two main sources. One is the gravitational pull of the earth, which forces your heel to fall in the absence of an external force.

Because it is difficult to form a stable support structure on tiptoe alone. The other force is the force that you subjectively lift your heel upwards through muscle contraction. Only when the magnitude of these two forces is the same, your legs will not shake up and down and back and forth.

But after all, it's a human, not a machine. It is difficult to control the relative stability of this upward lifting force. (Muscle fatigue, voluntary or unconscious lifting, etc.)

So two trends are formed. When you subjectively want to keep your leg in a fixed position, there are two situations: natural lifting and natural relaxation. Jitter generated.
