The study aimed to evaluate the impact of selected exerkines concentration induced by folk-dance and balance training on physical performance, insulin resistance, and blood pressure in older adults. Participants (n = 41, age 71.3 ± 5.5 years) were randomly assigned to folk-dance (DG), balance training (BG), or control group (CG). The training was performed 3 times a week for 12 weeks. Physical performance tests-time up and go (TUG) and 6-min walk test (6MWT), blood pressure, insulin resistance, and selected proteins induced by exercise (exerkines) were assessed at baseline and post-exercise intervention. Significant improvement in TUG (p = 0.006 for BG and 0.039 for DG) and 6MWT tests (in BG and DG p = 0.001), reduction of systolic blood pressure (p = 0.001 for BG and 0.003 for DG), and diastolic blood pressure (for BG; p = 0.001) were registered post-intervention. These positive changes were accompanied by the drop in brain-derived neurotrophic factor (p = 0.002 for BG and 0.002 for DG), the increase of irisin concentration (p = 0.029 for BG and 0.022 for DG) in both groups, and DG the amelioration of insulin resistance indicators (HOMA-IR p = 0.023 and QUICKI p = 0.035). Folk-dance training significantly reduced the c-terminal agrin fragment (CAF; p = 0.024). Obtained data indicated that both training programs effectively improved physical performance and blood pressure, accompanied by changes in selected exerkines. Still, folk-dance had enhanced insulin sensitivity.
这项研究旨在评估民间舞蹈和平衡训练所引起的特定运动因子浓度对老年人身体表现、胰岛素抵抗和血压的影响。参与者(n=41,年龄 71.3±5.5 岁)被随机分配到民间舞蹈组(DG)、平衡训练组(BG)或对照组(CG)。训练每周进行 3 次,共 12 周。在基线和运动干预后评估身体表现测试——起立行走测试(TUG)和 6 分钟步行测试(6MWT)、血压、胰岛素抵抗和运动引起的特定蛋白(运动因子)。TUG(BG 为 p=0.006,DG 为 p=0.039)和 6MWT 测试(BG 和 DG 均为 p=0.001)、收缩压(BG 为 p=0.001,DG 为 p=0.003)和舒张压(BG 为 p=0.001)显著改善。这些积极变化伴随着脑源性神经营养因子的下降(BG 为 p=0.002,DG 为 p=0.002),两组内鸢尾素浓度的增加(BG 为 p=0.029,DG 为 p=0.022),以及 DG 组胰岛素抵抗指标的改善(HOMA-IR 为 p=0.023,QUICKI 为 p=0.035)。民间舞蹈训练显著降低了 C 端神经胶质细胞衍生神经营养因子片段(CAF;p=0.024)。研究结果表明,两种训练方案都能有效改善身体表现和血压,同时还伴有特定运动因子的变化。尽管如此,民间舞蹈训练还有助于提高胰岛素敏感性。
