简要总结
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.
详细描述
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.

研究组 & 干预措施
intensive sport practice
intensive sport practice
- the subject must practice for more than six months a drive of at least 8 hours / week, intense, above the ventilatory threshold, or 60-70% of maximum consumption oxygen 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.
- volunteers,
- from 18 to 80 years,
- free to consent.
- covered by social security.
- reported in the national register of healthy volunteers.
The intervention is a lower limb venous examination = venous mapping
干预措施: venous mapping (Procedure)
control group
&) Volunteers who do not have intensive sport practice as it is defined in the group "intensive sport practice" 2) from 18 to 80 years, 3) free to consent. 4) covered by social security. 5) reported in the national register of healthy volunteers.
