Treinamento de sobrecarga muscular n?o afeta o diametro das principais veias dos membros inferiores em mulheres adultas com insuficiência venosa

摘要

Physical exercise can promote benefits in the functionality of the venous system. However, in the strength training context, contraindication concerning its practice is observed, since it can be related to worsening of venous dysfunctions. OBJECTIVE: To analyze the effects of resistance exercises practice on venous diameter of physical inactivity women with chronic lower limb venous insufficiency. METHODS: Twenty-two women with age between 21 and 58 years (34.27 ± 12 years) were randomized divided in two groups: experimental (n = 12) and control (n = 10). The resistance training was carried out over a period of 16 weeks and the venous diameter measurements were determined at the left lower limb Great and Small saphenous veins by a color Eco- Doppler. Two-way ANOVA was used to determine the modifications in veins diameter between groups and training moments (pre and post) (p < 0.05). RESULTS: Statistically significant alterations were not found in smaller saphenous vein diameter (upper, medium and lower points: p = 0.80; 0.32 and 0.20, respectively), great saphenous vein on leg level (p = 0.17; 0.74 and 0.96) and great saphenous vein on thigh level (p = 0.57; 0.67 and 0.52). CONCLUSION: Resistance exercise practice can be considered a treatment or intervention since it does not promote changes on the venous diameter of the venous system of women with chronic lower limb venous insufficiency.
