分组模拟训练的２８８只兔股骨标本病理观察及扭断试验结果表明，较大强度和时限训练的主导作用是加速骨塑形改建，增强抗骨折能力。分３组经３种方法训练的１８０只大鼠的胚骨上段病理切片及电镜观察表明，强化循环训练组的改建完成率（４１．７％）高于其它两组（２６．１％，２１．９％），而应力性骨折发生率（１１．５％）则低于其它两组（２２．９％，１８．８％）。对１１２９名新兵１２周基础训练的前瞻性流行病学调查证实，下肢长管状骨经历约９周的应力性塑形改建期，训练的第２、７周出现的应力性骨折高发的双峰现象可随训练强度与时限的加大或减少，而提前或延迟出现。在训练中采用“强化循环训练法”将加速骨的塑形改建及降低应力性骨折发生率。
The pathological observation and the twisting test results of 288 rabbit femoral specimens simulated by grouping simulation showed that the leading role of training with greater intensity and time-limit was to accelerate the remodeling of bone shape and enhance the ability of resisting fracture. The pathological sections of the upper part of the embryo and the electron microscopic observation of 180 rats trained by 3 methods showed that the rebuilding completion rate (41.7%) in intensive cyclic training group was higher than that in the other two groups (26.1%, 21 .9%), while the incidence of stress fractures (11.5%) was lower than the other two groups (22.9%, 18.8%). A prospective epidemiological investigation of 1129 recruits for 12 weeks of basic training confirmed that long mandibular lower extremity experienced a stress reshaping period of about 9 weeks and a bimodal phenomenon of high stress fractures occurring 2 and 7 weeks after training With training intensity and time limit increase or decrease, but in advance or delay. In the training of “intensive cycle training method” will accelerate the reconstruction of the bone shape and reduce the incidence of stress fractures.
