Effects of training and 17-B estradiol upon heart rates, organ weights, and liganientous strength of female rats

  • Frank W. Booth
  • Charles M. Tipton


The effects of training in 3 different female rat populations (NOR, OV, and OV + EST) were studied. Trained rats were exercised in motor driven treadmills for 9 weeks and were capable of running at speeds in excess of 1 mile per hour for 1 h at the end of the training program. OV rats did not appear to be different than the other rats in their ability to run in the treadmills. Three training effects were observed in the OV and NOR rats: lower body weights, lower resting heart rates and heavier adrenal glands. Two unexpected findings were the failure of trained female rats to have heavier hearts or stronger knee ligaments.
