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

为探讨为期32周的游泳训练对哮喘儿童运动时血液生化指标及心率和摄氧量的影响，以11名7~11岁哮喘儿童(其中7名症状轻微，4名中、重度)和6名非哮喘儿童(7~11岁)为对照。在室内游泳池进行为期32周的游泳训练，其中哮喘患儿的免疫球蛋白均值为984.5±291.6 IU/ml，非哮喘患儿的免疫球蛋白均值为147.3±113.4 IU/ml，但经过32周的游泳训练，哮喘患儿的免疫球蛋白均值降至461.0±212.2 IU/ml。在游泳训练开始时，哮喘儿童的血脂(NEFA和甘油三酯)浓度显著高于…组非哮喘儿童游泳32周后与非哮喘儿童比较差异无统计学意义(P&lt；0.05)。62)哮喘儿童安静时和运动后10min的乳酸平均浓度均显著高于非哮喘儿童(P&lt；0.05)。但游泳训练32周后，哮喘儿童与非哮喘儿童相比差异无统计学意义。虽然哮喘儿童游泳训练开始时休息时和运动后10min的摄氧量均值显著高于非哮喘儿童(P&lt；0.05)，但在游泳训练32周后哮喘儿童的摄氧量明显下降(P&lt；0.05)。游泳训练将有助于日常生活中运动量较少的哮喘儿童的体能发展。较少

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.
