[Effects of various sport activities on peripheral venous diseases].

The study of the influence of different sporting activities on peripheral venous pathology should be based on venous physiology and precise understanding of the technology of each sport (study of the movements, positions, and muscles brought into play, the rhythm, the material employed, the risks run). At the conclusion of a long study on sportsmen of both average and highly competitive ability, and on yogis, the author was able, by means of a simple methodology applicable to all physical activity, to classify the principal sports into two categories: those which improve and those which work against the peripheral venous circulation. However he does not recommend a complete ban on the harmful sports in highly motivated patients, but rather that they should counter the disadvantages by performing antagonistic movements.
