Compare the frequency of varicose veins in the lower limbs in a population exposed to intensive sport compared to individuals matched by sex, age and body mass index (BMI) did not have an intensive sport.
Chronic venous disease is a very common disease in industrialized countries. The prevalence of this disease is estimated in France 30.1% in men and 50.5% women.
Sufferers report pain, heaviness and itching of the lower limbs, and these symptoms are increased at night and in a warm environment. Clinically chronic venous disease resulting in varicose veins (veins visible under the skin, tortuous and dilated), edema (swelling predominant at the ankles) and in the later stages include skin damage of up 'to the ulcer.
The pathological mechanisms underlying chronic venous disease are mainly related to incontinence of the valves of the veins of the lower limbs. The initial role of these valves is to allow the return of blood to the heart and prevent it falls constantly in the legs. A breach of these valves therefore will result in an alteration of venous return and dilatation of the affected veins. It will be highlighted by a venous reflux when analyzing Doppler.
A number of parameters have been identified as factors favoring chronic venous disease in the lower limbs. Thus heredity (family history of venous disease), age, number of pregnancies among women, a history of phlebitis, overweight and physical inactivity increase the risk of chronic venous disease.
The effects of physical activity:
The practice of physical activity helps fight against physical inactivity. It is recognized as a protective factor against chronic venous disease. That is why the French and international companies of medicine and vascular surgery have incorporated in their recommendations to patients the practice of moderate physical activity and regular part of the prevention and treatment of chronic venous disease.
Moreover, the impact of intensive practice of a sport (versus "moderate and regular physical activity") of chronic venous disease is not known. Assumptions were issued from the nineteenth century on the possible risk of fostering the emergence of chronic venous disease at an excessive sports. Thus, from the 1820s Dr. Rima Thomas, surgeon of Napoleon's army, stated: "inertia as much as excessive activity come together to produce the same effect, the varicose vein." This idea is still relevant, in fact some experts recommend, at this time, intensive sports wear compression devices in the lower limbs during sports practice to prevent this phenomenon. However, no study has established a link between intensive practice of sport and venous condition of the legs.
The purpose of the study:
VARISPORT The study will aim to analyze the condition of the veins of the lower limbs in two groups of voluntary individuals, aged 18 to 80 years, in the same population:
- An "intensive sport practice": This group will consist of men and women who practice for more than 6 months, a drive of at least 8 hours / week, intense, above the ventilatory threshold, or 60-70 % maximum oxygen consumption or 70- 80% of maximum heart rate, ie beyond a moderate slowdown. If stopping the intensive sport practice, the duration of the stop at the time of the study should be less practice time.
- A "control" group: the subjects included in this group will have profiles that approximate subjects of the group "intensive practice sports", same sex, same age, BMI close; but the practice of a sport is less than 8 hours per week.

Skin breakdown or ulceration caused by varicose veins in which there is too much hydrostatic pressure in the superficial venous system of the leg. Venous hypertension leads to increased pressure in the capillary bed, transudation of fluid and proteins into the interstitial space, altering blood flow and supply of nutrients to the skin and subcutaneous tissues, and eventual ulceration.
Catheters that are inserted into a large central vein such as a SUBCLAVIAN VEIN or FEMORAL VEIN.
Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
The venous trunk of the upper limb; a continuation of the basilar and brachial veins running from the lower border of the teres major muscle to the outer border of the first rib where it becomes the subclavian vein.
