| Research Abstract |
(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

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. Less
