BMI AND CARDIAC PHYSIOLOGICAL PARAMETERS OF SECONDARY SCHOOL PUPILS OF SOME ETHNIC GROUPS IN KONTUM
Objectives: Research the index morphology and physiology of the pupil in the ages of 11 to 14. Subjects and Methods: Subjects the pupil in the ages from 11 to 14 years including Kinh, Dẻ, Xê Đăng, Rơ Ngao and Mơ Nâm. Researching indicators include: BMI, heart rate, arterial blood pressure. Methods: Routine methods were standardized to examine the morphological and physiological indicators. Results: (i) Research results show that in the period from 11 to 14 years the index morphology and physiology of the pupil is still not stable. (ii) Height and weight increases with age class. The change in height and weight make changes in BMI. (iii) Based on BMI can see that most pupils are not provided adequate nutrition. Conclusion: In the period 11-14 years, operation of the circulatory system is stabilized gradually, heart frequency decreases but blood pressure increases with age
