The effects of strenuous maternal exercise throughout gestation on the maternal rat were examined. The results indicated that maternal exercise of this nature (30 metres/minute, 10 degree incline, 120 minutes/day, 5 days/week) caused a significant decrease in the amount of weight gained by the running maternal rats when compared to controls. By analysing the maternal rat and various bodily components after parturition, it was suggested that subcutaneous tissue growth (fat deposits and mammary gland tissue) was significantly less in the running group. The carcass remainder component was also found to weigh less in the running group, even though the maternal running rats had just given birth to an equivalent (not significantly different) number of neonates of similar (not significantly different) weight to the control group.
研究了孕期剧烈运动对母鼠的影响。结果表明，与对照组相比，这种强度的母鼠运动（30米/分钟、坡度10度、每天120分钟、每周5天）导致跑步的母鼠体重增加量显著减少。通过分析产后母鼠及其各个身体组成部分，发现跑步组的皮下组织生长（脂肪沉积和乳腺组织）明显较少。还发现跑步组的胴体其余部分重量较轻，尽管跑步的母鼠刚刚产下数量与对照组相当（无显著差异）、体重与对照组相似（无显著差异）的新生鼠。
