Submaximal physical exercise by sedentary men and women on a bicycle ergometer for 60 min at 58% (men) and 55% (women) of VO2 max. was evaluated for its effect on the number of total leukocytes (WBC), lymphocytes, monocytes and neutrophils and the percentages of CD3+, CD4+, CD8+ and CD19+ lymphocyte subpopulations, as well as on IgA, IgG and IgM serum immunoglobulin levels as one measure of B-lymphocyte function. Blood samples were collected before, immediately after, and 15 minutes after physical exercise. Exercise did not significantly change the total number of WBC, lymphocytes, monocytes or neutrophils, or the percentages of CD3+, CD4+, CD8+ and CD19+ positive cells and the IgA and Ig M immunoglobulins. However the serum level of IgG immunoglobulins immediately after exercise was significantly lower than both before (p < 0.001) and 15 min later (p < 0.05). No differences in the results between men and women were detected.
让久坐不动的男性和女性在自行车测力计上进行次最大强度体育锻炼，持续60分钟，强度为男性最大摄氧量的58%、女性最大摄氧量的55%。评估此次锻炼对总白细胞（WBC）、淋巴细胞、单核细胞和中性粒细胞数量，以及CD3 +、CD4 +、CD8 +和CD19 +淋巴细胞亚群百分比的影响，同时评估其对作为B淋巴细胞功能指标之一的血清免疫球蛋白IgA、IgG和IgM水平的影响。在体育锻炼前、锻炼结束后即刻以及锻炼后15分钟采集血样。锻炼并未显著改变WBC、淋巴细胞、单核细胞或中性粒细胞的总数，以及CD3 +、CD4 +、CD8 +和CD19 +阳性细胞的百分比和IgA与IgM免疫球蛋白。然而，锻炼结束后即刻的血清IgG免疫球蛋白水平显著低于锻炼前（p < 0.001）和锻炼后15分钟（p < 0.05）。未检测到男性和女性的结果存在差异。
