Objectives: We investigated whether different durations of voluntary exercise in rats during transition from the growing period to adulthood would have any positive effects on bone structure of tibiae in adult rats.
Methods: Male Sprague-Dawley rats (5 weeks old) were divided into six groups: (1) 10SC (n=6), sedentary controls housed in normal plastic cages until age 15 weeks; (2) 10VE (n=7), housed in a voluntary-exercise (running-wheel) device equipped with housing space until age 15 weeks; (3) 30SC (n=7), sedentary controls housed in normal plastic cages until age 35 weeks; (4) 30VE (n=7), housed in the voluntary-exercise device until 35 weeks; (5) 10C20E (n=7), housed in normal plastic cages until age 15 weeks, then in the voluntary-exercise device from age 16 weeks to 35 weeks; (6) 10E20C (n=10), housed in the voluntary-exercise device un..
