The aim of this study was to obtain data on the incidence of muscle tightness and joint hypermobility in relation to growth velocity and physical fitness in a group of 120 children at the ages of 8, 12 and 16 years. In this longitudinal study, each child was examined at least three times within each 4-years period. It was established that muscle tightness, once developed, remained constant unless treated. The correlation between the incidence of muscle tightness and height is statistically significant, particularly in boys. The incidence of muscle tightness increased from age 8 to age 16 years and then remained constant. Increasing weight and height and poor physical fitness can be considered as predisposing factors for the development of muscle tightness.
