The purpose of this study was to assess the effect of Nordic walking training on the indices of bone and carbohydrate metabolism in relation to 25(OH)D levels in postmenopausal women that were subjected to the outdoor systematic physical activity. The study was performed in 10 postmenopausal women, who participated in a 12-week Nordic walking exercise program, taking place during spring months (March to June). Anthropometric and biochemical parameters were measured before and after the training program. Serum concentrations of 25-hydroksycholekalciferol (25(OH)D), parathyroid hormone (PTH), insulin, glucose, osteocalcin (OC), C-terminal telopeptide of type I collagen (CTX), and calcium were determined. After the Nordic walking exercise program, a significant increase in the serum levels of 25(OH)D and CTX and a decrease in body mass, body mass index (BMI), fat mass, and PTH concentrations were observed. The findings of the present study suggest that 25(OH)D, as important metabolic regulator, plays a role in the modification of bone markers' responses after the outdoor training program, independent of the physical activity effects.
本研究旨在评估北欧行走训练对骨代谢和碳水化合物代谢指数的影响，以及与户外系统体育活动相关的 25（OH）D 水平。该研究在 10 名绝经后女性中进行，她们参加了为期 12 周的北欧行走锻炼计划，时间为春季（3 月至 6 月）。在训练计划前后测量了人体测量学和生化参数。测定了血清 25-羟维生素 D（25（OH）D）、甲状旁腺激素（PTH）、胰岛素、葡萄糖、骨钙素（OC）、I 型胶原 C 端肽（CTX）和钙的浓度。在北欧行走运动项目后，血清 25（OH）D 和 CTX 水平显著升高，体重、体重指数（BMI）、体脂和 PTH 浓度降低。本研究结果表明，25（OH）D 作为重要的代谢调节剂，在户外训练计划后对骨标志物反应的调节中起作用，独立于体育活动的影响。
