Quantitative research of bone tissue related to physical activity (PA) and sport has a preventive dimension. Increasing the parameters of bone tissue strength, especially reaching the maximum value of peak bone strength in childhood, adolescence, and early adulthood due to practicing sports can contribute to maintaining bone health throughout life. Practicing martial arts (tai chi, traditional karate, judo, and boxing) can effectively improve the quality of bone and reduce the risk of falls and fractures. The study aimed to evaluate the calcaneus bones among Okinawa Kobudo/Karate Shorin-Ryu practitioners using the quantitative ultrasound method as an indicator for assessing bone fracture risk. Forty-four adult martial arts practitioners with a mean age of 36.4 participated in this study. Quantitative ultrasound (QUS) with a portable Bone Ultrasonometer was used in this study. Speed of sound (SOS), broadband ultrasound attenuation (BUA), and the stiffness index (SI) were measured. Subjects were assigned to two groups of black and color belts, according to the advancement in Kobudo/karate practice. The measurements of the SI, BUA, SOS, T-score, and Z-score were significantly higher in subjects from the advanced, long-term practice (black belts) ( < 0.05). The long-term martial arts training in traditional karate and Kobudo significantly impacts the parameters of the calcaneus quantitative ultrasound measurements. Significantly higher bone density was observed among the black belt holders. Long-term practice subjects achieved results far beyond the norm for their age groups. Further studies using non-invasive methods of bone quantification are needed to determine the specific conditions for preventing osteoporosis through physical activity, sports, and martial arts, particularly the duration of the activity, the magnitude of loads, and other related factors.
与身体活动（PA）和运动相关的骨组织的定量研究具有预防作用。通过运动增加骨组织强度的参数，特别是在儿童、青少年和成年早期达到峰值骨强度的最大值，可以有助于维持终生的骨骼健康。练习武术（太极拳、传统空手道、柔道和拳击）可以有效地改善骨骼质量，降低跌倒和骨折的风险。本研究旨在使用定量超声方法评估冲绳空手道/空手道松涛流练习者的跟骨骨骼，作为评估骨折风险的指标。44 名平均年龄为 36.4 岁的成年武术练习者参加了这项研究。本研究使用便携式骨超声仪进行定量超声（QUS）。测量了声速（SOS）、宽带超声衰减（BUA）和刚度指数（SI）。根据空手道/空手道练习的进展，将受试者分为黑带和色带两组。在高级、长期练习（黑带）的受试者中，SI、BUA、SOS、T 评分和 Z 评分的测量值显著更高（<0.05）。传统空手道和空手道的长期武术训练对跟骨定量超声测量的参数有显著影响。黑带持有者的骨密度明显更高。长期练习的受试者的结果远远超过了其年龄组的正常值。需要使用非侵入性的骨定量方法进行进一步研究，以确定通过身体活动、运动和武术预防骨质疏松症的具体条件，特别是活动的持续时间、负荷的大小和其他相关因素。
