摘要
通过观察桑拿高温脱水恢复期运动时免疫细胞的变化,并与常温条件下相同运动负荷时相比较,探讨桑拿高温脱水恢复期运动对免疫细胞的影响。方法:16名身体健康的体育系男子大学生随机分为两组单纯运动组(n=8)和桑拿后运动组(n=8),分别在不同条件下进行递增负荷运动:(1)常温条件,25℃,相对湿度60%;(2)进行桑拿浴后,常温条件,25℃,相对湿度60%;并分别测试递增负荷运动前安静时、运动后即刻、恢复1h和恢复24h受试者外周血白细胞总数、中性粒细胞数目、淋巴细胞数目和单核细胞数目。结果:(1)两组白细胞总数在运动后即刻均非常显著升高(P<0.01),恢复1h基本达到安静水平;(2)单纯运动组中性粒细胞数目,运动后即刻非常显著增高(P<0.01),恢复1h有所下降(P<0.05)仍高于安静(P<0.01),恢复24h基本达到安静值;桑拿后运动组中性粒细胞数目,运动后即刻显著增高(P<0.05),恢复1h基本达到安静水平;(3)两组淋巴细胞数目和单核细胞数目运动后即刻均非常显著升高(P<0.01),恢复1h基本达到安静水平。结论:以上结果表明,桑拿高温脱水恢复期运动时,中性粒细胞数目增多有限并能快速恢复,可能是桑拿作用降低了机体对运动的应激性,这对提高机体的运动能力有一定的积极意义。
Objective： To compare the number of immunocyte during acute exhausting exercise under a common temperature condition without taking a sauna with those during the same workload and under the same condition after a sauna.Methods： Sixteen unacclimated men were divided into the control group（n=8） and the sauna group（n=8） randomly.They respectively performed an incremental test to exhaustion on a treadmill under a common temperature condition（25℃,relative humidity 60%） without taking a sauna and the same condition（25℃,relative humidity 60%） after a sauna.We tested the content of WBC,neutrophil,lymphocyte and monocyte at AR,IMPEX,postexercise 1h and postexercise 24h.Results：（1）the TWBC increased highly significant（P0.01）at IMPEX and recovered at postexercise 1h（P0.05）;（2） the content of neutrophil in the control group increased highly significant（P0.01）at IMPEX and decreased at postexercise 1h（P0.05）but unrecovered（P0.01）,and recovered at postexercise 24h;the content of neutrophil in the sauna group increased significantly（P0.05）at IMPEX and recovered at postexercise 1h;（3） the contents of lymphocyte and monocyte increased highly significant（P0.01）at IMPEX and recovered at postexercise 1h.Conclusion：These findings demonstrated that the content of neutrophil in the sauna group increased limitedly and recovered quickly after acute exhausting exercise.It may be indicated that excitability to exercise decreased after a sauna.It is positive to raise the motor ability.
