Title: [Effects of self-generated LBNP training on cardiovascular function and lower body negative pressure (LBNP) tolerance]. Author: Yang CB, Sun XQ, Wang YC, Liu TS, Feng DY, Yao YJ. Journal: Space Med Med Eng (Beijing); 2004 Jun; 17(3):192-5. PubMed ID: 15920846. Abstract: OBJECTIVE: To explore the changes of cardiac function and lower body negative pressure tolerance after self-generated Lower Body Negative Pressure device training and provide experimental evidences for its appliance. METHOD: Twelve healthy male subjects were randomly divided into two groups, and received training on two conditions for entirely closing the valve or opening to -30 mmHg of peak LBNP separately. The group A was trained for five days and three minutes per day. Heartfunction, HUT and tolerance of LBNP were measured in pre-training, 3 d and post-training. The group B was trained for ten days and five minutes each day. All the measurements that was the same as in group A were made. RESULT: Heart function of group A decreased and tolerance of LBNP increased significantly (P<0.05). In group B, heart function increased significantly after 8 days training, so did tolerance of LBNP. CONCLUSION: It suggested that lower body negative pressure tolerance could be improved by self-generated Lower Body Negative Pressure device training. The changes of cardiac function, however, were based on the project of training.[Abstract] [Full Text] [Related] [New Search]
