Effects of Short Periods of Physical Training upon Body Weight of White Mice

Abstract

Fifty-one white mice were randomly assigned to three groups. The animals in group 1 were exercised daily on a motor-driven treadmill for eighteen successive days. The mice in group 2 were required to swim daily for eighteen successive days. The members of group 3 received no special exercise. Using covariance procedure, the adjusted mean body weights of the three groups were compared. It was concluded that, despite the ad libitum provision for food, the body weights of the exercised mice were lower than those of the sedentary group. Further, the animals who swam weighed less than those trained on the treadmill.
