A study on locomotion characteristics according to the level of cardiorespiratory endurance in adolescents

This study aims to investigate the differences in locomotion characteristics according to cardiorespiratory endurance in adolescents. The subjects were 51 students in the third grade of middle school, divided into the EG group (excellent group) and NEG group (non-excellent group) according to the cardiorespiratory endurance level. This study investigates the differences in locomotion characteristics according to cardiorespiratory endurance in adolescents. We used a 20-shuttle-run for cardiorespiratory endurance level, and a 1-minute walking test was performed for each speed by applying a differential speed. Cardiorespiratory endurance variables were based on VO 2 Max, and locomotion variables were analyzed by spatial-temporal parameters and foot range of motion parameters. Regarding the locomotion spatial-temporal parameters, adolescents with excellent cardiorespiratory endurance showed a more regular pattern, while foot inversion showed a more abnormal pattern. In particular, when the locomotion speed was slow, these characteristics were more clearly distinguishable. Our results confirm the characteristics of locomotion according to the growth of adolescents and can mediate the difference in walking speed to use as a primary database for the locomotion of adolescents.
