Poster Session I: Exercise physiology

Abstract

P106 What is the best way to improve the venous blood flow in the lower limbs? K Shimizu, HK Hirano Toho University Medical Center, Sakura, Japan Topic: Exercise physiology, testing and training Purpose:We studied to reveal the most efficacy methods for improvement of the venous blood flow in lower limbs using elastic stocking, intermitted pneumatic massage pomp(IPC) and combination of them. Veno Stream was selected as most superior IPC in our past study.Subject:30 healthy volunteers participated in this study. Method: Using a ultrasonograhy, we measured peak of the blood flow rate (cm/s) in superficial femoral vein. The examination went by the following method. At resting, maximal exhalation, ankle plantar flexion, dorsal flexion, rotation of the ankle, kicking at the bed edge exercise, and IPC were done and measured peak of the blood flow rate. Then, the same contents were done with elastic stocking. Results:The blood flow rate at the rest of the right foot was 26.01 2.59, maximal exhalation was 29.05 2.89, ankle plantar flexion was 42.84 4.20,dorsal flexion was 58.39 5.73, rotation of the ankle was 51.39 4.63, kicking at the bed edge exercise was 38.07 3.51 and IPC was 55.08 6.72. With elastic stocking, rest was 22.84 3.43, dorsal flexion was 47.02 3.79, and IPC was 52.12 2.95. The most effective exercise was dorsal flexion. (p<0.05)Conclusion: The combination of IPC and elastic stockings was not superior to IPC alone. We do not show enough blood flow improvement effects only with elastic stocking worn. To prevent venous thrombosis in patients, we should have right knowledge about blood flow improvement.
