A Theoretical Estimation Of The Range Of The Unknown Parameter K, Presented In The Model Of Carter Et.,Al., (1987) For The Case Of Distance-Running

摘要

In this work we theoretically determined the range of the unknown parameter K, presented in Carter’s et., al.,(1987) theory for the case of distance-running.We expressed the density of the distal- end of the femur of a distance-runner, in terms of his (her) training history. After that we used some published data and we concluded that 0 < K <0.3206 mg.cm3/ N1/2. Introduction Many years ago Carter et., al., (1987) proposed a theory for inter-nal bone remodeling. The basic idea of this theory was that the ap-parent bone density ρ, is expressed in terms of daily loading histo-ry. The last mathematically is approximated by the following equa-tion:
