The purpose of the study was to assess the association of cartilage metabolism biomarkers and vitamin D metabolite levels with muscle biomechanical functions in professional rowers and canoeists. The serum levels of aggrecan, cartilage oligomeric matrix protein (COMP), and 25-hydroxyvitamin D (25(OH)D) were determined in elite male sweep-oar rowers (n = 24) and canoeists (n = 15). This was followed by a biomechanical study consisting in isometric measurement of peak torque (PT) of muscles involved in the rowing cycle in the athletes. There were found significant correlations of COMP with the ratio of trunk PT flexor to extensor (p < 0.05) and 25(OH)D with trunk PT-left rotators (p < 0.05), knee joints PT-left and right flexor (p ≤ 0.01), ratio of knee joint PT-right flexor to knee joint PT-right extensor (p < 0.05) in rowers and aggreccan with elbow joint PT of the right flexor (p ≤ 0.01) and extensor (p = 0.05) in canoeists. The correlations of COMP and aggrecan levels with PT of the muscle groups studied in rowers and canoeists indicate the importance of stabilizing the muscular system in cartilage metabolism. The relationship between 25(OH)D status and biomechanical parameters confirm that vitamin D plays an important role in maintaining skeletal muscle health.
本研究旨在评估软骨代谢生物标志物和维生素 D 代谢物水平与职业赛艇运动员和皮划艇运动员肌肉生物力学功能的相关性。在精英男性赛艇运动员(n=24)和皮划艇运动员(n=15)中测定了软骨聚糖、软骨寡聚基质蛋白(COMP)和 25-羟维生素 D(25(OH)D)的血清水平。随后进行了一项生物力学研究,包括对运动员划桨周期中参与的肌肉进行等长峰值扭矩(PT)的测量。结果发现,在赛艇运动员中,COMP 与躯干 PT 屈肌/伸肌比值(p<0.05)和 25(OH)D 与躯干 PT-左旋肌(p<0.05)呈显著相关;在皮划艇运动员中,COMP 与膝关节 PT-左、右屈肌(p≤0.01)和膝关节 PT-右屈肌/右伸肌比值(p<0.05)呈显著相关,而 aggrecan 与右肘关节 PT 屈肌(p≤0.01)和伸肌(p=0.05)呈显著相关。COMP 和 aggrecan 水平与赛艇运动员和皮划艇运动员研究的肌肉群 PT 的相关性表明,稳定肌肉系统在软骨代谢中非常重要。25(OH)D 状态与生物力学参数之间的关系证实了维生素 D 在维持骨骼肌肉健康方面的重要作用。
