A study of physical fitness as body temperature,blood biochemical constituents and hormone on children in water. - Special reference on children with bronchial asthma -

为探讨游泳训练对7-11岁哮喘儿童血液生化指标、运动时心率和摄氧量变化的影响，以11名7-11岁哮喘儿童（7名轻度，4名中重度）和6名7-11岁非哮喘儿童为对照组，进行为期32周的游泳训练。在室内游泳池进行每周2次、每天1小时半的游泳训练32周后，支气管哮喘患儿血清免疫球蛋白（IgE）平均值为984.5 <plus-minus>~ 291.6IU/ml，非哮喘患儿为147.3 <plus-minus>~ 113.4IU/ml，而哮喘患儿<plus-minus>经32周游泳训练后下降至461.0 ~ 212.2IU/ml。游泳训练开始时，哮喘儿童的血脂（NEFA和甘油三酯）浓度显著高于对照组， 关于我们 游泳训练32周后，哮喘儿童与非哮喘儿童的乳酸浓度无显著性差异（P&gt; 0.05）。62）哮喘儿童安静时和运动后10 min的乳酸浓度均显著高于非哮喘儿童（P &lt; 0.05）。游泳训练32周后，哮喘儿童与非哮喘儿童相比，运动后10 min和休息时的摄氧量均值无显著性差异，但游泳训练开始时哮喘儿童的摄氧量均值显著高于非哮喘儿童游泳训练32周后，哮喘儿童的运动能力明显下降（P &lt;0.05），游泳训练对日常生活中运动量较少的哮喘儿童的体能发展有一定的促进作用。少

The purpose of our investigation is to evaluate the effect of swimming training for thirty-two weeks for asthmatic children on blood biochemical constituents and changes of heart rates and oxygen uptakes while doing exercises.Subjects were eleven asthmatic boys aged 7-11 years old (7 with mild symptoms, 4 moderate and severe ) and 6 non-asthmatic boys ( aged 7-11 yeras old ) as controls. Swimming training were given for thirty-two weeks, twice a week , one hour and half each day in an indoor swimming pool.The mean values of immunoglobulin ( IgE ) in children with bronchial asthma were 984.5 <plus-minus> 291.6 IU/ml, and non-asthmatic children 147.3 <plus-minus> 113.4 IU/ml , respectively ,However , those values in asthmatic children decreased to 461.0 <plus-minus> 212.2 IU/ml after swimming training for thirty-two weeks. At the beginning of swimming training , the concentrations of the serum lipids ( NEFA and triglyceride ) in asthmatic children were significantly greater than those in … More non-asthmatic children ( P < 0.05 ) , while no significant differnces between asthmatic and non-asthmatic children were observed after thirty-two weeks of swimming tra1.62 )The mean concentrations of lactic acids at rest time and 10 minutes after doing exercise were significantly greater in asthmatic children than in non-asthmatic children ( respectively ,P < 0.05 ). However , after swimming training for thirty-two weeks , those in asthmatic children were no significant differences compared with non-asthmatic children.Although the mean values of oxygen uptake at rest time and 10 minutes after doing exercises were significantly greater in asthmatic children than in non-asthmatic children at the beginning of swimming training ( P < 0.05 ) , those in asthmatic children showed significant decreases after swimming training for thirty-two weeks ( P < 0.05 ).Swimming training will be useful to promote th development of physical fitness on children with bronchial asthma who have less amount of exercise in their daily life.
