Abstract
This study clarifies the relationship between the quantity of physical activity intensity levels and the physical fitness of male and female students of different ages. Using a questionnaire, physical activity was studied based on student engagement in passive activity (under 3METs) and low (under 6METs)- to moderate (over 6METs) -intensity dynamic activity. The results of this study show significant difference in the rate of low-intensity dynamic activity of pubescent females only. This rate is highest in elementary school students followed by middle school students and high school students respectively. The rate of moderate-intensity dynamic activity of both pubescent males and females is highest in elementary school, followed by middle school students and high school students respectively. The rate of moderate-intensity dynamic activity was generally higher in males than females. Middle school males who practice moderate-intensity dynamic activity performed better in physical fitness tests than middle school males who do not practice moderate-intensity dynamic activity. Based on the findings of the study, there is an inverse relationship between the practice of physical activities and the age of pubescent males and females. This trend is prominent in pubescent females specially. In addition, physical activity tends to influence physical fitness of 14-year-old middle school males in particular.
