The Effects of Long Term Swimming Training on Children with Bronchial Asthma - a Study of Physical Fitness on Immunity Function, Blood Constituents and Hormones -

为探讨长期游泳训练对哮喘儿童体能的影响(1989年11月至1991年3月，每周1次，每次1h)，对6~11岁哮喘儿童8例(轻度4例，中度2例，重度2例)和6~12岁哮喘女孩10例(轻度10例)进行体能训练，并以1名非哮喘儿童和1名非哮喘儿童为对照组，分别于1989年12月、1990年3月、1990年7月、1990年12月、1991年3月进行5次测量。FEV1.0，PFR)、血液成分(RBC、WBC、Hb、红细胞压积)、免疫球蛋白E(IQE)、前列腺素(Pg F)，并在递增负荷的自行车上进行运动，测量心率、呼吸频率、氧摄取。结果：哮喘患儿的FVC、FEV1.0、PFR无明显改善，说明哮喘患儿的健康状况良好，IgE均值1989年12月为1124.1±1064.3 IU/ml，1991年3月为911.0±795.5 IU/ml，但未见明显差异。98.26pg/ml，各测定时间间未见显著差异。运动最大摄氧量每周1次，每次游泳1小时，对哮喘儿童体能发展有促进作用。

The present study was to investigate the effects of physical fitness on children with bronchial asthma for long term swimming training (from November 1989 to March 1991, once a week, for one hour each time).Subjects were 8 asthmatic boys aged 6-11 years old (4 with mild symptoms, 2 moderate and 2 severe) and 10 asthmatic girls aged 6-12 years old (10 with mild symptoms), and 1 non-asthmatic boy and 1 non-asthmatic girl who were used as control.Measurements were taken 5 times on December 1989, March 1990, July 1990, December 1990 and March 1991.The measurement items were pulmonary ventilating function(FVC. FEV1.0, PFR), blood constituents(RBC, WBC, Hemoglobin, Hematocrit), immunoglobulin E(IqE), prostaglandins(PG F), and the subjects exercised on bicycle ergometer with a gradual increase load to measure HR, respiratory frequency, O2 uptake. Result : FVC, FEV 1.0 and PFR did not improve, and it seems that the values are showing the deqree of health on asthmatic children.The mean values of IgE were 1124.1 <plus-minus> 1064.3 IU/ml on December 1989 and 911.0 <plus-minus> 795.5 IU/ml on March 1991, but we could not find any significant differenThe mean concentrations of PG F2 were 288.0 <plus-minus> 98.26 PG/ml, and we could not find any siqnificant differences among each measurement timAs for max values of O2 uptake at doing exercises, there is a limit to promote the development of physical fitness on asthmatic children an amount of once a week and one hour each time swimming.
