Morphological mensuration of bone moulding reconstruction accelerated by “cyclic intensive training” and the influence of intervention in human beings / 解放军医学杂志

ABSTRACT

Objective The purpose of this study is to evaluate the effects of intensified cyclic training on bone moulding reconstruction, and to found the scientific basis of intensific cyclic training as a new training methods. Methods 48 male rats were equally divided into two groups: intensive repetitive training group and control group. The upper segment of tibia was harvested from the animals at the 1st, 2nd, 3rd, 4th, 5th and 6th week after the onset of the experiment for the measurement of cortical thickness (CT), mean wall thickness (MWT) and the percentage of osseous surface of trabeculae and surface area of trabecular Absorption (Sr). The data of intensive repetitive trained group were compared with those of the control group. 1 303 recruits were divided into control group and experimental group. In the experimental group, they were trained by intensive repetitive training program instead of the traditional training program. The incidence of stress fracture was compared between two groups. Results CT (1.37?0.09, 1.86?0.14, 1.94?0.23), MWT (56.37?2.52, 57.28?3.01, 58.23?2.93) and Sos (12.29?1.17, 14.61?1.84, 15.51?1.13) were higher in the training group than control groups at the fourth week, the fifth week and the sixth week, respectively (P
