宇航员可以在月球上的圆柱体内运行,以创造人造引力. 这种全身运动有助于防止长期太空任务期间的骨损失和脱节.
科学领域:
- 太空医学 太空医学
- 人体生理学 人体生理学
- 生物机械工程 生物机械工程
背景情况:
- 低重力暴露,就像在月球定居点一样,会导致肌肉缩,骨质损失和脱节.
- 目前的应对措施是不够的,全身运动如移动是比孤立的肌肉训练更喜欢的.
- 像走路和跑步这样的运动步态在月球引力下更快的速度有异常的动态.
研究的目的:
- 研究一种用于在月球上产生人工引力的新方法.
- 评估在气内使用水平运行的可行性,作为对太空飞行引起的脱水的对策.
- 确定这种方法是否能提供足够的机械负荷以防止骨去矿化.
主要方法:
- 理论分析和实验验证在4.7米半径的气内水平运行.
- 模仿月球重力,通过使用杆跳跳带卸下83%的体重.
- 在高速水平跑步 (5.4-6.5 m/s) 期间测量代谢速率和峰值力.
主要成果:
- 参与者成功地以5.4-6.5米/秒的速度水平跑,经历了高的人工重力.
- 强烈的新陈代谢 (54-74 mlO2 kg-1 min-1) 和峰值足接触力是体重的2-3倍被记录下来.
- 这些力量相当于陆地跑步,足以刺激骨维护.
结论:
- 在圆柱体内水平运行是一种可行的方法,可以在月球上产生显著的人工引力.
- 这种"全身"运动方案可以作为有效的对抗措施,防止宇航员的肌肉和骨脱节.
- 每天几圈的训练可以显著改善宇航员在长期月球任务和返回地球后的健康状况.

Acceleration due to Gravity on Other Planets
Astronomical observations are thus used to measure the acceleration due to gravity on other planets. This can be determined by observing the effect of a planet's gravity on objects close to it. The crucial factor that helps in this...

Measuring Acceleration Due to Gravity
A simple pendulum can be described as a point mass and a string. Meanwhile, a physical pendulum is any object whose oscillations are similar to a simple pendulum, but cannot be modeled as a point mass on a string because its mass is distributed over a larger area. The behavior of a physical pendulum can be modeled using the principles of...
