The effects of swim-training on choice of dietary fat, carbohydrate or protein, weight gain, energy intake, and energy efficiency were examined in ovariectomized and sham-operated retired breeder rats. After a 3 week training period of increased duration, rats swam for 75 min per session (5 days per week) for 4 weeks. Ovariectomized rats gained more weight than sham rats, while swimming reduced weight gain and abdominal fat. As a percentage of total intake, macronutrient choices (weight and energy) were similar for all groups, ovariectomized animals consumed more food and more energy, compared with sham animals. All rats freely chose the majority of their food (g) as carbohydrate and the majority of energy (kJ) as fat. Results indicate that a moderate intensity training program of swimming prevented the weight gain following ovariectomy in older rats despite their excessive caloric intake of fat.
在去卵巢和假手术的老年繁殖大鼠中，研究了游泳训练对膳食脂肪、碳水化合物或蛋白质选择、体重增加、能量摄入和能量效率的影响。经过为期3周的延长训练期后，大鼠每周游泳5天，每次游泳75分钟，持续4周。去卵巢大鼠比假手术大鼠体重增加更多，而游泳可减轻体重增加和腹部脂肪。作为总摄入量的百分比，所有组的常量营养素选择（重量和能量）相似，与假手术动物相比，去卵巢动物消耗更多的食物和能量。所有大鼠自由选择的食物大部分（克）为碳水化合物，大部分能量（千焦）为脂肪。结果表明，适度强度的游泳训练计划可防止老年大鼠去卵巢后体重增加，尽管它们摄入了过多的脂肪热量。
