A Research of Preparing for Exercise-Prescrioption Norm of Health Promoting for Children with Bronchia Asthma.

(一)目的：本次调查的目的是。(2)研究对象：选择非哮喘儿童60名(男5名，女5名，2年级、4年级、6年级各5名)和35名同龄哮喘儿童(2岁、4岁、6岁)。男生12年级、4年级、15年级和6年级男生8年级：平均Ig E=6956“*”291.3 IU/m l)。(3)测量方法和测量项目：在一年的运动强度和体育教材负荷水平上测量心率。采用自行车功率计递增负荷(100%HRmax和80%HRmax强度)对60名非哮喘儿童和35名哮喘儿童进行递增负荷，并测定HR、VO_2、FEV_2和白细胞(Eos…(4)体育课时80%以上HRmax强度的教材是与2年级玩标签游戏，4年级玩足球，4年级女生玩耐力跑，6年级男生玩篮球耐力跑，6年级女生玩耐力跑。在100%最大心率运动时，非哮喘四年级男生的呼吸频率为51.6“*”7.05次/分。相比之下，哮喘男孩的结果是49.7“*”13.86f/min。我们找不到他们之间有任何显著的差异。而哮喘男童的呼气量和摄氧量均值显著低于非哮喘组(P&lt；0.01)。非哮喘男童在运动后即刻和运动后15min的FEV_lt；1.0和Gt；值均较高。而哮喘男童的FEV_(1.0)和FEV_(1.0)在运动后即刻和运动后15min较安静时下降约15%或更多。在80%HRmax运动时，哮喘儿童与非哮喘儿童在呼吸频率、呼出气量和VO2方面无明显差异。哮喘儿童中性粒细胞平均值在运动后有下降的趋势。80%HRmax运动后即刻的嗜酸性粒细胞均值与100%运动后即刻相比有升高的趋势，但与安静时间相比无明显差异。(5)结论：在80%HRmax运动负荷的低强度下，哮喘儿童与非哮喘儿童一样，即静息时心率的1.6~1.7倍。较少

(1) Purpose : The purpose of this investigation is. to prepare of a norm for health promoting prescription with the level of exercise intensity and load of teaching materials of physical education at elementary school for children with bronchial asthma.(2) Objects : Non-asthmatic children in elementary school were selected in all sixty children (each 5 children of male and female on grade 2^<nd>, 4^<th> and 6^<th>) And thirty-five Asthmatic children were selected with same years old age (2^<nd> grade boys 12, 4^<th> grade boys 15 and 6^<th> grade boys 8 : average value of IgE = 695 6"*"291.3 IU/ml).(3) Methods and measurement items : HR were measured at the level of exercise intensity and load of teaching materials of physical education through a year. Sixty non-asthmatic children and thirty-five asthmatic children were included in this exercise by using bicycle ergometer to increase load gradually (l00%HRmax and 80%HRmax intensity) and measured HR, VO_2, FEV_<1.0> and leulkocytes (eos … More inophil, neutorophil).(4) Results : Teaching materials over 80%HRmax intensity during physical education class periods were playing tag game with 2^<nd> grade, soccer for 4^<th> grade boys, a endurance running for 4^<th> grade girls, basketball and a endurance running for 6^<th> grade boys, and a endurance running for 6^<th> grade girls. HR of these exercises were more than the 1.73 times to HR at rest.At the 100%HRmax exercise, respiratory frequencies were 51.6"*"7.05 f/min in 4th grade non-asthmatic boys. In contrast, the result was 49.7"*"13.86 f/min in asthmatic boys. We could not find any significant differences between them. However, the mean of exhaled gas and VO2 uptake of asthmatic boys were significantly lower than non-asthmatics (P<0.01). FEV_<1.0> of non-asthmatic boys showed high values immediately after exercise and 15 min after exercise. On the other hand, FEV_<1.0> of asthmatic boys were showing about 15% or more to decrease immediately after exercise and 15 min after exercise compared at rest.At the 80%HRmax exercise, we could not find any significant differences between asthmatic and non-asthmatic boys on respiratory frequencies, amount of expired gas and VO_2.The mean values of neutorophils showed a tendency to decrease after exercise at asthmatic children. The mean values of eosinophils at the immediately after 80%HRmax exercise showed a tendency of increase compared with immediately after 100%I{Rmax exercise.However, we could not find any difference in comparison with resting time.(5) Conclusion : As a teaching material of physical education, we could treat asthmatic children as same as non-asthmatic children at the lower intensity of 80%HRmax exercise load, that is 1.6-1.7 times of HR at rest.
