恒定功率不同持续时间运动对红细胞免疫功能的影响

The Effect of Exercise of Constant Power and Different Duration on the Immunologic Function of Erythrocyte

恒定功率三种不同持续时间运动后，受试者 ＲＢＣ－Ｃ３ｂＲ活性显著降低，其下 降程度与运动持续时间密切相关，亚运动 ３，小时仍显著低于安静值。 １５ｍｉｎ和 ３０ｍｉｎ 组运动后，受试者 ＲＢＣ－ＩＣ花环率有增高趋势，但无显著性；而 ４５ｍｉｎ组运动后却 显著增高，至运动 ３小时仍高于安静值（ Ｐ＜ ０． ０５）。三组受试者运动后 １５小时，二种花环率均恢复至安静水平。

After the exercise of constant power for three different duration, the actevity of RBC - C3bR of the testees has made a remarkable declination, whose falling degree has a close relation with the duration of the exercise. It is remarkably below the value of quietness after 3 hours of exercise. After the exercise of 15 - minute group and 30 - minute group; the RBC- IC rosette rate of the testees has a rising trend which is not striking; but the 45 minute group has a remarkable rising and it is still above the value of quietness (P< 0. 05) after 3 hours of exercise. 15 hours after these three groups of testees exercised, the two rosette rates recovered to the state of quietness.
