Information regarding osteogenic effects of physical activity performed on different playing surfaces is scarce. A total of 42 children (9.2±0.2 years, Tanner stages I-II) participated in this study. 14 were playing on artificial turf soft ground (SG), 14 on a natural non-grass hard ground (HG) and 14 were assigned to the sedentary control group (C). Whole body and hip scans (dual energy X-ray absorptiometry), anthropometric variables (weight and height) and physical fitness (VO2max) were determined in all participants. Bone mineral content (BMC) values were higher in the SG group compared to the C group at the legs (209.75±5.11 g vs. 187.42±5.14 g, respectively), pelvis (122.72±4.27 g vs. 98.58±4.29 g respectively) and whole-body level (1 126.1±22.81 g vs. 1 035.34±22.92 g, respectively). The hard ground (HG) group also showed higher values in the majority of BMC variables compared to the C group. Additionally, bone mineral density (BMD) was significantly higher at all sites of the hip in both active groups compared to control (P<0.05). No differences between HG and SG were found. In summary, similar bone mass accretion is obtained by prepubescent footballers independently of the surface on which they practice football.
关于在不同场地进行的体育活动对成骨作用的信息很少。共有 42 名儿童（9.2±0.2 岁，Tanner 分期 I-II）参与了这项研究。其中 14 人在人工草皮软地上（SG），14 人在天然非草地硬地上（HG），14 人被分配到久坐对照组（C）。所有参与者均进行全身和髋部扫描（双能 X 射线吸收法）、人体测量变量（体重和身高）和体能（VO2max）。与 C 组相比，SG 组腿部（209.75±5.11g 与 187.42±5.14g）、骨盆（122.72±4.27g 与 98.58±4.29g）和全身水平（1126.1±22.81g 与 1035.34±22.92g）的 BMC 值更高。与 C 组相比，硬地（HG）组在大多数 BMC 变量中也表现出更高的值。此外，与对照组相比，两个活跃组在髋关节的所有部位的骨矿物质密度（BMD）均显著升高（P<0.05）。HG 和 SG 之间没有差异。总之，青春期前的足球运动员无论在何种场地进行足球训练，都能获得相似的骨量增加。
