Investigating the Correlation between Range of Motion of Joints with the Time of Running Types in Adolescent Elite Runner Girls Participating in National Competitions in 2018 in Ardabil City: A Descriptive Study

Background and Objectives: The relationship between range of motion of joints with running time is important to achieve athletic success. The aim of this study was investigating the correlation between range of motion of joints with the time of running types in adolescent elite runner girls participating in 2018 national competitions in Ardabil city. Materials and Methods: In this descriptive study, subjects were 122 elite runner girls, 14-16 year, participated in the national championship of the country selection. Range of motion of joints was measured by Rydkov questionnaire. Pearson᾽s correlation coefficient was used to examine the correlation between variables. Results: There was a positive significant correlation between elbow flexion (r=0.407, p=0.048) and 60m hurdle running time, between hip hyperadduction (r=0.531, p=0.005) and 400m running time, trunk flexion (r=0.656, p=0.001) and 800m running time, neck extension (r=0.646, p=0.001) and neck lateral bending to left (r=0.563, p=0.006) and 3000m running time, trunk lateral bending to right (r=0.418, p=0.028), trunk lateral bending to left (r=0.382, p=0.045), shoulder abduction (r=0.379, p=0.047) and hip hyperextension (r=0.398, p=0.038) and 4×100m relay race time. Whereas, there was a negative significant correlation between ankle dorsi flexion (r=-0.464, p=0.022) and 60m hurdle running time, between ankle inversion (r=-0.442, p=0.030) and 800m running time, shoulder hyperextension (r=-0.473, p=0.017) and 1500m running time, and ankle eversion (r=-0.440, p=0.040) and 3000m running time. Conclusion: It seems that there is a significant correlation between the range of motion of joints and running time in elite runner girls. So, it is suggested that coaches pay attention to the results of this study for getting more success in reaching the peak of athletic performance.
