ABSTRACT Effect of Physical Activity on Health Related Physical Fitness and Metabolic Syndrome risk factors in Overweight Male High School Students

Shin, Se-Hoon Advisor : Prof. Seo Young-Hwan, Ph.D. Department of Physical Education, Graduate School of Chosun University

The purpose of this study was to compare male high school overweight students(overweight group: 15) to male high school normal students(normal group: 15) in physical activity(BMR, total energy expenditure, exercise volume, step counts and physical activity intensity level), metabolic syndrome risk factors(insulin, fasting glucose, waist circumference, HDL cholesterol, blood pressure) and physical fitness(muscular strength, muscular endurance and flexibility). The following results were obtained from this study:

1. The comparison of physical activity variables: Total energy expenditure, exercise volume, step counts and physical activity intensity level of overweight group were statistically significantly lower than those of the normal group(p<.05). Only BMR of overweight group was statistically significantly higher than that of the normal group(p<.05).

2. The comparison of physical fitness variables: Muscular strength of overweight group was statistically significantly higher than that of the normal group(p<.05). Muscular endurance and flexibility of overweight group were statistically significantly lower than those of the normal group(p<.05).

3. The comparison of metabolic syndrome risk factor variables: Fasting glucose, TG, and diastolic blood pressure of overweight group were lower than those of the normal group and HDL-C of overweight group was higher than that of the normal group but these were no statistically significant difference. Abdominal circumference and systolic blood pressure of overweight group were statistically significantly higher than those of the normal group.

4. The comparison of metabolic syndrome factor counts: In normal group only four people had one metabolic syndrome factor and the rest of the people in the same group had no metabolic syndrome factor, meanwhile two people had one factor, six people had two factors, five people had three factors, and two people had four factors.

Through all of abovementioned results, the different amount of physical activity caused significant change in metabolic syndrome risk factors and physical fitness, especially normal group showed more and less significant difference. Various participation of physical activity may significantly contribute to metabolic syndrome risk factors and physical fitness. It is necessary to study in more cases for the students to encourage them to enhance the amount of their physical activity by establishing program. Additionally, with the influx of new educational curriculum, it is essential that education system change to encourage them to be more active in their physical activity by cognizing the importance of physical activity.
