Lactic acid is a movement regulator of the human body. When it is strenuously exercised, fat is decomposed into calories and lactic acid (so fat people are relatively more prone to produce lactic acid). Lactic acid stimulates nerves and causes pain and fatigue.
Lactic acid is also a kind of physical protection measure, because too intense or sustained strong exercise will pull the muscles to damage the body's function, so under high-intensity exercise, the body will correspondingly inhibit people's activity ability, make people feel tired and extraordinary. Pain in order to prevent excessive physical exercise harming the body.
It is also a major side effect for athletes to provide exercise level lactic acid, which not only makes people unable to exert super-level ability, but also makes long-term fatigue after high-intensity exercise (especially anaerobic exercise), so professional athletes not only have extraordinary sports. Ability, but also have the ability to resist pain caused by lactic acid. Recommended attention
Although lactic acid has side effects on exercise, it also has its good side. Lactic acid can be decomposed during exercise. A large amount of lactic acid can stimulate the expansion of blood vessels and connective tissue (fitness exercise is to use this principle). Swelling makes muscles more powerful. Faster blood circulation and faster blood circulation can make the blood deliver oxygen more quickly (so the leg muscles of professional cyclists are very soft and not as firm as rock, because such muscles have good blood circulation).
Within a few hours after exercise, even if the body is still, it will secrete a large amount of lactic acid, so it will be even worse to rest immediately after exercise, because lactic acid will decrease with the blood circulation rate in that part of the muscle tissue and cause fatigue feeling. The rise, so it is best to stop before hanging a small number of teeth than riding a rest.
On the second day after exercise, the body will still produce lactic acid, so on the second day after strenuous exercise, it is necessary to walk around and ride, because blood circulation and muscle exercise can help the body to metabolize lactic acid, making the body feel more relaxed (if it has been from the day When you are lying home until the next day, you will feel more tired.
There are several ways to relieve fatigue and metabolize lactic acid:
1, massage is the best method, professional athletes often use masseurs to squeeze muscles for their massage, to help them release the lactic acid in the muscles, to deal with the next day's game in a better state, of course, amateur riders do not have such In good conditions, you can also help yourself by pressing your muscles.
2, warm bath can effectively promote blood flow, but also a good way to release lactic acid.
3, adequate sleep is conducive to the recovery of physical fatigue, if not enough sleep, even if not strenuous exercise, the body will feel very tired, this is the reason.
4, eat more vegetables can help metabolism of lactic acid, eating too much meat is also bad for lactic acid metabolism.
Lactic acid is produced when anaerobic respiration occurs in muscles. It will not be quickly decomposed or absorbed. It is only allowed to follow the blood circulation. Because our exercise consumes a lot of oxygen, the anaerobic respiration of muscles can be repeated. Inevitably.
During riding, it is necessary to avoid the rapid accumulation of lactic acid that causes sore thighs. Pay attention to the following aspects:
1: Don't change the speed ratio very quickly, as the muscles need to do a lot of work. The lactic acid produced by anaerobic respiration is large, so try to avoid the possibility of excessive load.
2: Reduce the speed ratio and use a brisk frequency to pedal so that the lactic acid can be taken away by the blood as much as possible. This is also the way to relax and introduce lactic acid.
3: During cycling, the chance of stopping pedaling is reduced, because it is very easy to cause accumulation and it is impossible to promptly reduce the accumulation of lactic acid.
[bicycle to prevent pp pain method ready-made version]
Speaking of bicycle pp hurts, although there are countless articles have mentioned various ways to prevent and reduce pp pain, but it seems that none of the existing good version. When riding a bike, pp suffers from constant pressure and friction for a long time. Uncomfortableness is certainly possible. There are many common discomforts:
1. Long time pressure, uncomfortable blood circulation;
2, long stampede, the skin was uncomfortable with repeated friction;
3, pp and seat closely integrated, not ventilated, sweating sticky and uncomfortable;
4, long time riding, gluteus maximus fatigue and other uncomfortable.
Here's how to reduce these uncomfortable ways - Sort by importance
a) suitable seat
The so-called fit is that the width of the seat should be in line with the width of the pelvis, just to force the thick gluteus maximus. Too wide can interfere with the movement of the legs. When it is too narrow, it will be embedded in the pelvis, oppressed and worn out to the "important part". Is the seat to meet their own p-type.
b) Wear cycling pants
Cycling pants has many advantages: 1, with a protective pad, this soft not only comfortable to sit, pads are generally made of sweatmax material such as coolmax, you can suck the sweat on the skin to prevent the skin between Adhesion to each other, astringent, friction is not comfortable; 2, close, most of the cycling pants are tight, close to the skin, so when riding, it is between the pants and the seat friction, protect the skin, and There will be no folds on the skin, and in short, it will not be worn to the skin; 3. The materials for the trousers are relatively smooth. When sitting in the seat, it will naturally slide to a more comfortable position. A little force in the province, the gluteus maximus is less affected by a little force, and it can also be fatigued later.
c) Correct adjustment
Some riders do not like to bend and ride and think that it is hard to ride a bike straight to the body. In this case, most of the weight will fall on the pp. The pp will obviously hurt for a long time, so we must correct the car. The height of the handlebars and the weight of the handlebars are distributed over the five points of pp, hands, and feet, but it is impossible for the pp to be overstressed.
d) Correct riding posture
On the basis of correct adjustment, the force has been assigned to five points, but it is clear that the gravity of pp is still the largest, and immediately the first three, pp or there will be two unfavorable conditions, that is, high temperature and continuous oppression, Has been sitting in the seat, pp there is not ventilated, the temperature will rise higher, very uncomfortable; long blood circulation is not smooth, but also very uncomfortable, the solution is to ride a lift up and down, such as riding a ten Minutes to stand up and shake two cars, so that pp can be ventilated, blood can also be active.
Hey, if you often ride a long journey, you can consider changing this seat. The hole in the middle to reduce pressure and ventilation is very good, hey, like some details of the fake line. Hey, to say a bunch, should be complete enough, hope comrades that pp hurt can relieve some pain after seeing.
