Various dynamic works (R, M, R, 1, 2, 3, 4 and 5) were loaded on the aged and the young for 4 hours in order to make hourly observations of the hematologic changes produced. Following results were obtained:
1. The phagocytic action of neutrophiles was usually enhanced with the increase in the intensity of the load in the young, while, it usually decreased in the aged.
2. Generally, the number of leucocytes increased with the increase in the intensity of the load in the youg, while, it showed no significant increase in the aged till the steady astate was broken.
3. In the young, specific gravity of the blood increased in proportion to the intensity of the load, while, it increased in the aged even by the light load and was not proportional to the intensity of the load.
4. In the young, both the hemoglobin content and hematcrit value decreased during Lhe work, on the contrary, they showed an increase in the aged.
