全身振动作为长期失重飞行防护措施的研究进展

Whole Body Vibration as Countermeasure in Long Term Space Flight

作为太空中使用的防护措施，如跑台、自行车功量计等，在针对长期失重飞行所导致的骨丢失和肌肉萎缩方面存在较明显的不足。低频（10～100Hz）、低幅（〈100microstrain）的全身振动在运动员的肌肉锻炼和临床骨丢失防护研究中已经被证实有着良好的效果，本文对于近年来全身低频低幅振动的治疗效果、作用机制以及存在的争议进行了综述，并对其作为对抗措施在长期航天失重飞行中应用的可能性进行了初步分析。

Many countermeasures used in outer space, such as treadmill and bicycle ergometer, have been proved not to be effective enough for preventing astronauts from bone loss and muscle atrophy. Low- frequency from 10-100Hz and low-magnitude less than 100 microstrain whole-body vibration which is used in muscle exercise and treatment of bone loss in clinic and medical experiments, has indicated its great potential as an effective and convenient countermeasure in preventing from osteoporosisl This article discusses the effectiveness, mechanism and argument of whole body vibration in recent medical research, and analyzes the possibility of its usage in long-term space flight.
