| Research Abstract |
A new forced swimming apparatus for determining maximum swimming time in mice was devised for use in evaluations of the endurance capacity. of mice following various treatments with diet and drugs. A water current generated by circulating water with a pump was developed in a swimming pool. A spout and suction slit were contrived to generate a constant current while the strength of the current was regulated by a valve. The decrease of the leg kicking intervals of mice accompanying increase in the current speed was confirmation that the work load is adjustable by regulation of current speed. The hind legs were most used by mice in this apparatus when compared the kicking intervals to forelegs paddling intervals. That swimming time until fatigue was decreased with relationship to increasing current speed was confirmed in two strains of mice. As biochemical indexes, blood lactate and muscle glycogen levels corroborated the correlation between current speed and increase in work load. These results indicate that the apparatus employed in the present study offers many advantages in the evaluation of the endurance capacity of mice, and is useful for detecting the effects of diets and drugs on this capacity.
