近年来国内外医学研究表明,中老年人经常高架双腿可使腿部、心脏、头部甚至全身大为受益。具体表现以下二个方面: 1.减少下肢静脉倒流性疾病的发生:常见的下肢静脉倒流性疾病,包括下肢静脉曲张和下肢深静脉功能不全二种。下肢静脉血液的向心回流,依靠下肢肌肉泵产生的迫挤作用,心脏搏动所产生的舒缩力量,以及呼吸时胸腔的负压。此外,静脉内瓣膜的单向开放,也使得腿部的血液向心回流,不致于逆流。长期站立时,下肢静脉所承受的压力明显升高,血液容易在腿部瘀滞,使得血管管腔扩大,同时血管内高压使得瓣膜所承受的应力增加,最终 In recent years, medical studies at home and abroad show that the elderly often have elevated legs, heart, head and even the whole body greatly benefit. Specific performance of the following two aspects: 1. Reduce the incidence of venous reflux disease: Common venous reflux disease, including varicose veins and lower extremity deep venous insufficiency two. Lower extremity venous blood back to the heart, rely on the lower extremity muscle pump squeeze effect generated by the heart beat systolic and diastolic strength, and chest pressure during respiration. In addition, the unidirectional opening of the IV valve also allows the blood to flow back to the heart without reflux. Long standing, the lower extremity venous pressure was significantly increased, the blood easily stasis in the legs, making the blood vessel lumen expansion, while the intravascular pressure so that the stress caused by the valve increased eventually
