摘要：The purpose of this study was to pursue the effect of training upon the heart. The hypertrophy of the cardiac muscle was analyzed at the following three levels; l) organ 2) tissue 3) cell. The histological method, using Hematoxylin stain was adopted. The rats (Wistar) were compelled to make 6 minutes' running on the treadmill at the speed of 40m/min. every day for eight weeks successively. The results obtained were as follows: 1) The increase of the body weight in the exercise group was smaller than that in the control group, but the heart weight increased. The heart-body ratio in the exercise group was considerably greater than that in the control group. 2) The dross-sections of the heart (Ventricle) were made at the center of the heart axis and the breadth of the walls of the heart was measured. The ratio of hypertrophy of the heart was 9.3% in the right ventricle and 10.5% in the left ventricle. 3) The average cross area of the cardiac fibers in the exercise group was 452.4μ^2 in the right ventricle and 462. 4μ^2 in the left ventricle. 0n the other hand that in the control group was 402.2μ^2 in the right and 401.9μ^2 in the left. The ratio of hypertrophy of the cardiac fibers was 12.5% in the right and 15.5% in the left.
