Subatmospheric pressure applied to the human body from the iliac crest caudally (Lower Body Negative Pressure, LBNP) has been known to cause various central and peripheral cardiovascular reactions. We investigated the effects of such a LBNP maneuver on energy metabolism of human skeletal leg muscle. We tested the hypothesis whether an altered fluid distribution induced by LBNP may cause any effect on aerobic and/or anaerobic energy metabolism and cellular pH-regulation during isometric contraction monitored by 31P-MRS.
从髂嵴向尾端对人体施加低于大气压的压力(下体负压,LBNP)已知会引起各种中枢和外周心血管反应。我们研究了这种LBNP操作对人体腿部骨骼肌能量代谢的影响。我们检验了一个假设,即LBNP引起的液体分布改变是否会在通过31P-MRS监测的等长收缩过程中对有氧和/或无氧能量代谢以及细胞pH调节产生任何影响。
