【摘要】：目的:对比分析短期终止训练和持续大强度训练对游泳运动员气道反应性和肺通气功能的影响,结合分析相关炎性因子的变化,研究游泳运动员运动诱发支气管痉挛的可复性。方法:以36名青少年游泳运动员为研究对象,平均年龄15.97±1.1岁。其中,15名运动员终止训练或低强度恢复性训练为期2周,为实验组;选取同一教练组,正常强度训练的21名运动员为对照组。分别于2周前后进行肺功能测试和支气管激发试验。测试日晨起肘正中静脉采血,测试血常规及血清Ig E、IL-17。结果:1)首次测试,共检出13名运动员EIB阳性(36%),实验组5人(33%)、对照组8人(38%),组间比较无显著性差异;2)首次测试13名EIB阳性运动员中仅有5人出现哮喘类呼吸症状(EIA),实验组2人(13%)、对照组3人(14%),组间比较无显著性差异;3)停训2周后,实验组3名EIB阳性运动员转为阴性,EIB检出率显著低于对照组(20%vs.48%,P0.05);实验组运动员支气管激发试验FEV1下降百分比显著降低(10.53±8.19 vs.8.35±5.24,P0.05),而肺功能参数MEF50%显著升高(88.69±27.01 vs.91.13±26.93,P0.05);4)停训2周后,实验组运动员静脉血中性粒细胞计数(3.47±1.06 vs.3.13±0.97,P0.05)和中性粒细胞百分比(55.31±7.60 vs.51.25±8.31,P0.05)均显著降低,静脉血中性粒细胞计数显著低于对照组(3.13±0.97 vs.3.39±0.91,P0.05);中性粒细胞计数同支气管激发试验FEV1下降百分比之间相关性不显著(r=0.323,P0.05);实验组运动员血清IL-17含量显著降低(0.98±0.21 vs.0.83±0.10,P0.05),而血清Ig E未发生显著变化。结论:1)游泳运动员EIB具有可复性,短期终止训练在一定程度上可以促进EIB的恢复;2)EIB阳性运动员多无哮喘类主观症状,支气管激发试验的客观证据是明确诊断的必要条件。
[Abstract]:Objective: to compare the effects of short term termination training and continuous high intensity training on airway reactivity and pulmonary ventilation function of swimmers and analyze the changes of related inflammatory factors in order to study the recoverability of bronchiospasm induced by exercise in swimmers. Methods: 36 young swimmers were studied, with an average age of 15.97 卤1.1 years. Among them 15 athletes stopped training or low intensity restorative training for 2 weeks as experimental group and 21 athletes with normal intensity training as control group in the same training group. Lung function test and bronchial provocation test were performed before and after 2 weeks. Blood samples were collected from the median elbow vein from the morning of the test day, and the blood routine and serum Ig EJ IL-17 were tested. Result: 1) first test, A total of 13 athletes (36%) were found to be EIB positive, 5 (33%) in the experimental group and 8 (38%) in the control group. There was no significant difference between the two groups (2) only 5 out of 13 EIB positive athletes developed asthma respiratory symptoms (EIA) for the first time, and 2 (13%) in the control group. In group 3 (14%), there was no significant difference between the two groups. The positive rate of FEV1 in three EIB positive athletes in the experimental group was significantly lower than that in the control group (20 vs. 48 vs P0.05), the percentage of FEV1 decreased significantly in the bronchial provocation test of the experimental group (10.53 卤8.19 vs.8.35 卤5.24), while the pulmonary function parameter (MEF50%) was significantly increased (88.69 卤27.01 vs.91.13 卤26.93 P0.05) for 2 weeks. The neutrophil count (3.47 卤1.06 vs.3.13 卤0.97 vs.3.13) and the percentage of neutrophil (55.31 卤7.60 vs.51.25 卤8.31 vs.51.25) were significantly decreased in the experimental group. The neutrophil count in venous blood was significantly lower than that in the control group (3.13 卤0.97 vs.3.39 卤0.91g, P0.05), there was no significant correlation between the neutrophil count and the percentage of FEV1 decrease in bronchial provocation test (r = 0.323P), and the level of IL-17 in the serum of athletes in the experimental group was significantly lower than that in the control group (0.98 卤0.21 vs.0.83 卤0.10p0.05), while the serum Ig level was significantly lower than that in the control group (P < 0.05). E did not change significantly. Conclusion: (1) the EIB of swimming athletes is reversible, and the short-term termination of training can promote the recovery of EIB to a certain extent. 2) most EIB positive athletes have no subjective symptoms of asthma. The objective evidence of bronchial provocation test is the necessary condition for definite diagnosis.
