The relationship between anthropometric characteristics and hip joint flexibility among teenaged girls in football schools

The purpose of present study was to investigate the relationship between Anthropometric characteristics and hip joint flexibility among teenaged girls in football schools. The population of this study comprised 120 teenaged girls from football schools of Mashhad. 40 teenaged girls of the population with mean and standard deviation of age 13/90±0/84 years, weight 51/62±6/51 kg, and height 156/35±4/22 cm as subjects participated. The Anthropometric variables including calf length, tight length, calf circumference, hip circumference, knee diameter, pelvic width, and thickness of subcutaneous fat of iliac crest, iliac, front tight, middle of the calf, range of motion in flexion and extension were measured. The collected data were analyzed through descriptive statistics and Pearson correlation coefficient with significant level of p < 0.05. The results showed that there is a negative and significant relationship between thickness of subcutaneous fat in front tight, middle of the calf and the range of motion in hip flexion. However, there is a positive and significant relationship between pelvic width and the range of motion in hip extension. The results of the present study demonstrated that there is a relationship between thickness of subcutaneous fat and pelvic width and hip joint flexibility.
