The current study aimed to assess the potential of different exercises triggering an osteogenic response at the femoral neck in a group of postmenopausal women. The osteogenic potential was determined by ranking the peak hip contact forces (HCFs) and consequent peak tensile and compressive strains at the superior and inferior part of the femoral neck during activities such as (fast) walking, running and resistance training exercises. Results indicate that fast walking (5-6 km/h) running and hopping induced significantly higher strains at the femoral neck than walking at 4 km/h which is considered a baseline exercise for bone preservation. Exercises with a high fracture risk such as hopping, need to be considered carefully especially in a frail elderly population and may therefore not be suitable as a training exercise. Since superior femoral neck frailness is related to elevated hip fracture risk, exercises such as fast walking (above 5 km/h) and running can be highly recommended to stimulate this particular area. Our results suggest that a training program including fast walking (above 5 km/h) and running exercises may increase or preserve the bone mineral density (BMD) at the femoral neck.
本研究旨在评估不同运动在绝经后女性群体的股骨颈处引发成骨反应的潜力。通过对（快速）行走、跑步和抗阻训练等活动中股骨颈上下部分的峰值髋部接触力（HCF）和随之产生的峰值张应变和压应变进行排序，来确定成骨潜力。结果表明，与被认为是骨保护的基线运动（4km/h）相比，快速行走（5-6km/h）、跑步和跳跃会在股骨颈处引起更高的应变。跳跃等具有较高骨折风险的运动需要谨慎考虑，特别是在体弱的老年人群中，因此可能不适合作为训练运动。由于股骨颈上部脆弱与髋部骨折风险增加有关，因此可以强烈推荐进行快速行走（5km/h 以上）和跑步等运动，以刺激这一特定区域。我们的研究结果表明，包括快速行走（5km/h 以上）和跑步运动的训练方案可能会增加或保持股骨颈的骨矿物质密度（BMD）。
