A023: A Comparative Study on Executive Function in Adolescent Studentswith Different Levels of Cardiorespiratory Fitness

<bold>Background/ Purpose:</bold> Adolescence is an important period for the development of Cardiorespiratory Fitness and Executive Function. The better the Executive Function of teenagers, the stronger the ability to solve various complex problems in life and learning. At the same time, Cardiorespiratory Fitness, as the focus of extensive attention in the field of public health, not only plays an important role and significance in teenagers' physical health, but also promotes the development of brain function. Therefore, this study explored the differences of Executive Function between 13-18 years old adolescents with high and low Cardiorespiratory Fitness levels, which plays an important guiding role in the in-depth study of exercise interventions on Executive Function of adolescents. <bold>Method:</bold> Stratified random sampling was used to select 13–18-year-old junior and high school students in Shanghai as the research participants for Cardiorespiratory Fitness and Executive Function testing, including 111 girls and 125 boys. According to commonly used international measurement methods, 20mSRT was used as the standard for measuring Cardiorespiratory Fitness. According to the standard, 20mSRT scores were divided into two levels: P₇₀ and P₃₀, to determine the level of Cardiorespiratory Fitness. Among them, 20mSRT scores ≥ P₇₀ indicated high Cardiorespiratory Fitness levels, and 20mSRT scores &lt; P₃₀ indicated low Cardiorespiratory Fitness levels. Finally, 69 adolescents with high Cardiorespiratory Fitness levels and 75 adolescents with low Cardiorespiratory Fitness levels were selected, and a Dependent T-test was then conducted to compare the Executive Functions levels of adolescents with high and low Cardiorespiratory Fitness levels. <bold>Results:</bold> A statistically significant difference in inconsistent response time and consistent response time was observed among adolescents with different levels of Cardiorespiratory Fitness (<italic>t</italic>=2.197 and 2.147, respectively, <italic>P</italic> &lt; 0.05). Also observed was a statistically significant difference in refresh function response time among adolescents with different levels of Cardiorespiratory Fitness (<italic>t</italic>=3.326, <italic>P</italic> &lt; 0.01) and a statistically significant differences in the sub functions of conversion function among adolescents with different levels of Cardiorespiratory Fitness (<italic>t</italic>=2.194, 3.073, and 2.186, respectively, <italic>P</italic> &lt; 0.05). <bold>Conclusions:</bold> In addition to inhibitory function, there were significant differences in Executive Function between adolescents with high and low levels of Cardiorespiratory Fitness. The higher the level of Cardiorespiratory Fitness in adolescents, the better their performance in refreshing and converting in Executive Functions.
