Abstract:
This study was performed to investigate the exercise-induced stress in growing state in order to prevent the death during or after exercise. Thirty eight male and female subjects in junior high school were administered 5 minutes running test for 3 succesive years. Heart rate, blood pressure, electrocardiogram, and blood biochemical components were measured before and after 5 minutes running test. Prior to 5 minutes running test the investigation of the number of food intake and total steps a day were performed. The results obtained were as follows;
1) After 5 minutes running test, the subjects who had larger increment in CK-MB/ CK ratio walked fewer steps a day and had fewer number of food intake. And they had more drinks, especially juices.
2) In female subjects an excess of body fat was not a risk factor, but not in male subjects.
3) The subjects, who had larger increment in body fat than in body weight, tended to become higher levels in blood pressure and heart rate in resting than others.
4) The subjects, who walked more longer in 2 nd grade than 1 st grade in junior high school, tended to decrease the increment of heart rate before to immediately after 5 minutes running test.
5) Blood biochemical components were normal even if electrocardiogram was abnormal.
6) At 24 hours after 5 minutes running test, CK-MB/CK ratio and serum lipoperoxide levels increased and serum protein and albumin levels defreased in 3 rd grade in junior high school.
Consequently in order to prevent the death during or after exercise the investigation of food intake, total steps a day, and body fat must be administered before exercise sufficiently. And then electrocardiogram and blood biochemical components, especially CK-MB activity must be checked before, during, and after exercise testing.
