Sports participation has many benefits for the young athlete, including improved bone health. However, a subset of athletes may attain suboptimal bone health and be at increased risk for stress fractures. This risk is greater for female than for male athletes. In healthy children, high-impact physical activity has been shown to improve bone health during growth and development. We offer our perspective on the importance of promoting high-impact, multidirectional loading activities, including ball sports, as a method of enhancing bone quality and fracture prevention based on collective research. Ball sports have been associated with greater bone mineral density and enhanced bone geometric properties compared with participation in repetitive, low-impact sports such as distance running or nonimpact sports such as swimming. Runners and infantry who participated in ball sports during childhood were at decreased risk of future stress fractures. Gender-specific differences, including the coexistence of female athlete triad, may negate the benefits of previous ball sports on fracture prevention. Ball sports involve multidirectional loading with high ground reaction forces that may result in stiffer and more fracture-resistant bones. Encouraging young athletes to participate in ball sports may optimize bone health in the setting of adequate nutrition and in female athletes, eumenorrhea. Future research to determine timing, frequency, and type of loading activity could result in a primary prevention program for stress fracture injuries and improved life-long bone health.
参与体育运动对年轻运动员有诸多益处,包括改善骨骼健康。然而,一部分运动员的骨骼健康可能未达最佳状态,且应力性骨折风险增加。女性运动员面临的这种风险高于男性。在健康儿童中,高强度身体活动已被证明在生长发育过程中能改善骨骼健康。基于综合研究,我们阐述了推广包括球类运动在内的高强度、多方向负荷活动对于提高骨质和预防骨折的重要性。与参与重复性低强度运动(如长跑)或非冲击性运动(如游泳)相比,球类运动与更高的骨矿物质密度和更优的骨骼几何特性相关。童年时期参与球类运动的跑步者和步兵未来发生应力性骨折的风险降低。包括女性运动员三联征共存在内的性别差异,可能会抵消以往球类运动对预防骨折的益处。球类运动涉及多方向负荷以及高地面反作用力,这可能会使骨骼更坚硬且更抗骨折。鼓励年轻运动员参与球类运动,在营养充足以及女性运动员月经正常的情况下,可能会优化骨骼健康。未来关于确定负荷活动的时间、频率和类型的研究,可能会形成一个针对应力性骨折损伤的一级预防方案,并改善终身骨骼健康。
