Abstract

It seems to etiology, diagnosis of sports injuries, and evaluation of their treatment process for rehabilitation need the measurement of strength, flexibility and alignments of limbs. These measures are only useful when there are sufficient reference values for comparing. The aim of this study was to find out normative values of strength, flexibility, and alignment in lower limbs in recreational runners. 73 healthy runners with an average weight of 73.13(7.10) Kg, height of 177.70(5.39), age of 22.58(3.76) from Mazandaran province participated in this study. Their strength, flexibility and alignments of lower limbs were measured. Strength was normalized to weight. Values more than -2 standard deviations for flexibility and strength and between ±2 standard deviations for alignment were chosen as normative values. Some results of this study were: the mean of hip muscle extensor strength was 0.52 of body weight. In addition, hip external rotation ROM and Q angle mean were 63and 13.15 degree respectively. It seems that our finding (the normative values of aforementioned parameters) provides functional information for rehabilitation and improvement of sport performance.
