[Purpose] We investigated the effects of a specifically designed exercise program that focused on the arches of the foot and the forefoot (the "Building Osteo Neatly Exercise" program) in college-aged females. [Participants and Methods] Forty college-aged females were divided randomly into experimental and control groups. The experimental group underwent the Building Osteo Neatly Exercise program for 60 min once a week for 4 months. In both groups, the plantar pressure distribution and quantitative ultrasound parameters of the calcaneus (speed of sound and bone area ratio) were evaluated at the beginning and end of the study. The plantar pressure distribution during walking was measured using a pressure plate to evaluate the deviation from the ideal values for the following: contact time, contact duration, peak pressure time, and foot pressure, all measured in the rear foot (the external and internal sides), medial forefoot including (the hallux and second and third toes), and lateral forefoot (the fourth and fifth toes). [Results] After completing the program, the speed of sound and bone area ratio had increased significantly in the experimental group and were significantly higher than those in the control group. The experimental group showed significant improvements in the deviations from the ideal values in contact time and contact duration in the medial forefoot, all four parameters in the lateral forefoot, and pressure in the rear foot. [Conclusion] College-aged females who participated in the Building Osteo Neatly Exercise program once weekly for 4 months exhibited significant improvements in bone strength in the calcaneus and in foot function, as shown by the plantar pressure distribution. Further studies are needed to examine the outcomes of the Building Osteo Neatly Exercise program in an elderly population.
[目的] 我们调查了一项专门设计的、聚焦于足弓和前足的锻炼计划（“精心构建骨质锻炼”计划）对大学年龄段女性的影响。[参与者与方法] 40名大学年龄段女性被随机分为实验组和对照组。实验组每周进行一次60分钟的精心构建骨质锻炼计划，共持续4个月。在研究开始和结束时，对两组的足底压力分布以及跟骨的定量超声参数（声速和骨面积比）进行评估。使用压力板测量行走过程中的足底压力分布，以评估以下各项与理想值的偏差：接触时间、接触时长、峰值压力时间和足部压力，这些测量均在足跟（外侧和内侧）、内侧前足（包括拇趾以及第二和第三趾）以及外侧前足（第四和第五趾）进行。[结果] 完成该计划后，实验组的声速和骨面积比显著增加，且显著高于对照组。实验组在内侧前足的接触时间和接触时长与理想值的偏差、外侧前足的所有四个参数以及足跟压力方面均有显著改善。[结论] 每周参加一次精心构建骨质锻炼计划、持续4个月的大学年龄段女性，其跟骨骨强度和足部功能（如通过足底压力分布所示）有显著改善。需要进一步研究以考察精心构建骨质锻炼计划在老年人群中的效果。
