This study was designed to describe the growth and developmental distance curves of some physical fitness attributes chosen. The physical fitness attributes chosen were body linearity measured by stature, muscular strength by back strength, explosive strength and jumping ability by standing long jump, throwing ability by softball throw for distance, and running ability by 100m dash. These growth and developmental distance curves for 30 years could be described with considerably high precision by composite of three different functions; logistic function and 4th-degree polynomial for all attributes, and one of 2nd-degree polynomial, a type of truncated probability function and single vibration function. Then, each of these functions used was likely to reflect the nature of growth and developmental distance trend due to aging from childhood to maturity. The studies of this type have been reported only for physique attributes, so this was the first attempt regarding to physical fitness attributes.
