本文通过5·12大地震这一特殊的灾害对人类体适能的影响,运用文献资料法、分析法对人类抗灾体适能进行了深入的理论研究,认为人类抗灾体适能是人类在经历灾害时,维持身体与内外环境间平衡的能力,具体指个体维持自身与灾害发生时的自然环境、社会环境及生理环境相协调,最大限度地保持自身健康,减少灾害损失的能力。 Based on the impact of the special disaster of May 12 earthquake on human physical fitness, this paper conducts an in-depth theoretical study on the human being’s ability to resist natural disasters using the literature and data analysis method. In disasters, the ability to maintain a balance between the body and the environment inside and outside refers to the ability of an individual to maintain its coordination with the natural environment, social environment and physiological environment at the time of a disaster, to maximize its own health and reduce disaster losses.
