摘　　要：对递增负荷运动及恢复不同阶段大鼠卵巢及子宫的超微结构进行扫描电镜观察发现,卵巢上皮细胞形态、完整性及细胞间连接均出现明显改变,子宫上皮细胞微绒毛由轻度脱落到几乎完全缺失。结果表明,9周运动训练导致卵巢上皮及子宫内膜细胞的合成机能受阻,细胞呈现动情间期状态,与同期测定的低性激素水平及动情周期紊乱和抑制现象具有依从关系。经过4个动情周期的恢复,大鼠卵巢及子宫结构逐渐复原,为一可逆性变化过程。The purpose of this experiment was to explore the potential mechanisms of effects of structure changes on functions in rats ovary and uterus during progressive increasing training load and recovery courses. Scan electron microscope were used to observe the tissue uhrastructure. The major results were than the shape, integrity and conjunction of epithelium were markedly changed in ovarian. The epithelium of endometrium may find that the microvilli on cells decreased from lightness to seriousness, which indicated s diestrus. These changes ynthesizing function was inhibited, and cell mature was restrained, so that endometrium were in were consistent in lower sex hormones level, estrons cycle dysfunction in the same phase. The structure changes of rats＇ ovary and uterus were progressively recovered after 4 estrons cycles rest.
