Abstract

The purpose of this study was to evaluate the validity by observational evaluation of forward and backward roll movements in 116 male and female elementary school children in the 2nd, 4th, and 6th year, and clarify the development of them and their sex-related differences.<br>Based on VTR images of forward and backward rolls, kinematic analysis of movement factors such as those related to the center of the gravity of the body was performed. A total of 13 teaching staff members, graduate students, and undergraduate students specializing in health and physical education evaluated both movements by observation. To clarify the validity of the observational evaluation of forward and backward rolls, the agreement rate between the results of observational evaluation and those of movement analysis was evaluated.<br>The data on movement factors related to the center of the gravity of the body during forward and backward rolls were consistent with the results of observational evaluation. The agreement rate regarding the results of observational evaluation of forward and backward rolls among the observers was high. Observational evaluation of forward and backward rolls showed an increase in the proficiency level of these movements with the school year and no marked difference in either movement between the males and females. These results suggest the validity and reliability of the observational evaluation of forward and backward rolls.
