Advice 1: How to know the curves of the feet

Slender and long beautiful legs is the dream of most women. Sometimes offensive, casual comment can cause serious complexes and personal dramas. In order not to torment yourself with unnecessary doubts, you need to determine how real this problem.

The curvature of the foot can be divided into true and false. The true curvature caused by the bending of the bones. Such a problem requires consultation and treatment from podiatrist. Fortunately, this situation does not occur very often.
2
Usually, we are talking about about the curvature of the legs. In this case, the visibility of the curvature arises because of the unfavorable location of the soft tissue. The bones of the legs straight.
3
To determine whether you have curvature of the legs, you must remove your shoes and stand up straight on a flat surface. Put feet together and close your thighs tightly. Perfectly straight the feet should be in contact at three points - ankles, calves and knees. This creates four "skylight" above the knee, below the knee, above the ankle and between the foot and ankle. The true curvature of the feet is diagnosed in the absence of the two points of contact.
4
If there is no contact between the knee and calf, it is referred to as O-shaped curvature of the bones. If there is no contact of the ankles and calves, this defect is called X-shaped curvature.
5
If there is no only one point of contact in the region of the calf muscle - there is reason to speak of about the curvature of the legs.
6
Correct about the curvature of the legs is possible by means of special exercises. If you for some reason do not fit, then come to the aid of plastic surgery. About the curvature quite easily avoided with silicone implants or injections of your own fat.
7
If true the curve of the foot contour is generally fruitless. The only way to fix it is to seek the assistance of an orthopedic surgeon. In such cases, the doctor may perform the surgery for excision of the bones of the lower leg. For the bones in the desired position after the operation is applied the Ilizarov apparatus. It should be noted that this operation is a major surgery and has a lot of contraindications. Besides, it exists the risk of various complications. The rehabilitation period can be 2-3 months.

The easiest and most enjoyable way to get rid of the curvature of the legs is to pick the right clothes. For example, jeans and pants straight cut visually "straighten" any curvature. Mini skirts can be combined with tights with the large geometric pattern, or with boots-bottomtime. For too slim leg fit tights with horizontal stripes.

Advice 2: How to calculate the length of the curve

When calculating any length, remember that it is a finite quantity, that is just a number. If you mean the arc length of the curve, such problem is solved by using the definite integral (planar case) or a curvilinear integral of the first kind (the arc length). The arc AB is denoted IAV.

The first case (flat). Let IAV is set to a flat curve y = f(x). The argument of the function will change in the range from a to b and it is continuously differentiable this segment. Find the length L of the arc IAV (Fig. 1A). To solve this problem, break the reporting period into elementary segments ∆xi, i=1,2,...,n. As a result, the IAV will be divided into elementary arcs ∆Ui, plots the graph of y=f(x) at each of the elementary segments. Find the length ∆Li of an elementary arc approximately, replacing it with the corresponding chord. It is possible to increase in to replace the differentials and use the Pythagorean theorem. After the issuance of the square root of the differential dx will get the result shown in figure 1b.

The second case (arc IAV set parametrically). x=x(t), y=y(t), tє[α,β]. Function x(t) and y(t) have continuous derivatives on the interval this interval. Find their differentials. dx=f’(t)dt, dy=f’(t)dt. Substitute these differentials into the formula to calculate the length of the arc in the first case. Remove dt from the square root under the integral, put x(α)=a, x(β)=b and come to the formula for calculating arc length in this case (see Fig. 2A).

The third event. Arc IAV graph of a function given in polar coordinates ρ=ρ(φ) of the Polar angle φ during the passage of the arc changes from α to β. The function ρ(φ)) has a continuous derivative on the interval of consideration. In such a situation, the easiest way to use the data obtained in the previous step. Choose φ as a parameter and substitute in equations relating polar and Cartesian coordinates x=ρcosφ y=ρsinφ. Differentiate the formula and substitute the squares of the derivatives in the expression in Fig. 2A. After a bit of identical transformations that are based mainly on the use of trigonometric identities (cos)^2+(sinφ)^2=1 we obtain the formula for arc length in polar coordinates (see Fig.2b).
4
The fourth case (spatial curve, defined parametrically). x=x(t), y=y(t), z=z(t), tє[α,β]. Strictly speaking, we should apply the line integral of the first kind (the arc length). Curvilinear integrals calculated by translating them in ordinary certain. As a result, the practical answer remains the same as case two, the only difference is that under the root will appear in an extension term – the square of the derivative z’(t) (see Fig. 2C).

Advice 3: How to correct o-shaped legs

Curvature of the legs may be of different shapes (x - or o-shaped, and about). But no matter what form your legs, there are several different methods for correcting them. And they can be done at home and be administered and conducted by a physician.

First, you can start to dance. And it doesn't matter what type and style they will take, the main thing is that you courses of their liking. These dances can be quite artistic, and a ballroom, sport dances and dances in a modern style (i.e. hip-hop, street dance or anything else). However, it is worth noting the fact that to achieve the desired effect faster it in the classroom for ballroom dancing. The thing is that only this type of training is able to be on feet most of the load, and accordingly, to correct their curvature. But no matter what dance you choose, don't forget about patience and apply maximum efforts to achieve results.

Without surgery will help you to do special gymnastic exercises. Today there are a considerable number, so that from them you will be able to choose something for themselves. By the way, just try not to do this every time two or three of the same exercises and make several whole complex, because this is the only way you can affect different areas of the feet and to correct the curvature. The main condition of exercise - regular exercise because without it you will not be able to get your desired effect.
3
Finally, the third method that helps you to get rid of the o-shaped curvature of the legs - surgical correction. In some cases, not do without it. Incidentally, when carrying out operations apply the latest technology, so to be afraid in this case nothing. Before surgery, you will need to consult a doctor to consult with him. He can tell you about the shape of the curvature of your feet, and to discuss a possible outcome. The specialist will prescribe individual therapy (regardless of what form of curvature seen in you).
Note
The choice not only of the clinic but also the doctor treat with the utmost seriousness and caution. Because the whole outcome of the operation will depend almost entirely from the selection you have made.

Advice 4: How to fix the curvature of the legs exercises

When the ideal shape of the feet in standing position the knees and ankles one footand touch the knees and ankles another. A slight curvature of the legs can be corrected with special exercises – muscles pumped in the right places, and legsand gain a good shape.
How to fix the curvature of the legs exercises
Instruction
1
Define the shape of your feet. When O-shaped legsdiverge from the pelvis, ankle two feet touching and the knees, so they form the letter O. If, on the contrary, knees touching, and no ankle, footand have a X-shape.
2
Start each training session with stretching exercises of muscles for any curvature of the legs. Stand up straight, keep your back straight, pull your stomach. The muscles of the body should be relaxed. Bend your legsat the knee and grab her hand. The heel should touch the buttocks. Secure the pose for 5-10 seconds. You can do the same other footOh.

Then sit down, feetand straighten, put your hands behind your back. Pull the sock to the side of the heel, that the maximum tensioning of the lower leg. Perform 10 repetitions for each legI. through this exercise, X-shaped legsand eventually taking the perfect shape.
7
Relax the muscles after each series of exercises. Sit down and straighten your back. The leg clasp your hands and slowly raise. Hold in this position for 5 seconds. Then change legs. Hold the feetand close to one another. Make sure that the knees have not been bent.
Useful advice
Visually conceal crooked legs you can use clothes. For example, boots and mini-skirt, boots with fringe, bell bottoms, skirts the year externally adjust the shape of the feet.
