摘要

A gravitational fluctuation stress loading method capable of causing a new acute stress reaction in a subject or a laboratory animal is provided. A gravitational fluctuation stress loading method including at least one first stress-loading step (S1) of placing a stress load on the subject or the laboratory animal by means of microgravity is provided.
