CHANGES IN SERUM IMMUNOGLOBULIN LEVELS AND NEUTROPHILIC PHAGOCYTOSIS AFTER EXERCISE

This paper is intended to give the information we need about personal reactivity to transient loads for the object of estimating human physical fitness. For this purpose, both serum immunoglobulin levels and neutrophilic phagocytosis were assayed as indices to self-defense activities. To determine the later described reproducibility of experimental results, two independent experiments were made on two different groups-one consisting of twelve and the other of fourteen male voluntary students of our college-exercised in the playgroud. The serum levels of three immunoglobulins (IgG, IgA and IgM) and two complements (C3 and C4), prior to and immediately after exercise, were compared with each other. They rose without exception after exercise. Paired T-test revealed that in the group of twelve students, rises in IgG, IgA, C3, α-1-antitrypsin and transferrin were significant at P<0.1%, 5%, 5%, 5% and 0.1%, and in the group of fourteen rises in IgG, IgA, IgM, C3, C4, α-1-antitrypsin and transferrin were significant at P<1%, 0.1%, 1%, 0.1%, 0.1%, 0.1% and 0.1%, respectively. In the meantime, the neutrophilic phagocytosis (%) was significantly decreased immediately after exercise in both groups (P<1% and P<0.1% respectively).
