The risk of dementia increases with age. To mitigate this risk, we examined the effect of a square-stepping exercise (SSE) program on fall-related fitness and brain-derived neurotrophic factor (BDNF) levels. Twenty older adults in Korea were randomly assigned to either the experimental or control group (each group n = 10). Participants performed SSE for 70 min per session, twice a week, for 12 weeks with a certified instructor. The average age of the participants was 74.80 ± 6.763 years in the exercise group and 72.50 ± 6.519 years in the control group. The experiment group showed significant improvement (p < 0.01) in the lower muscle strength post-intervention. The paired t-test revealed a significant improvement (p < 0.01) in the experimental group and a significant difference in the interaction effect (p < 0.01) in the BDNF levels. There was a significant improvement (p < 0.05) in the BDNF levels in the experimental group and a significant decrease (p < 0.05) in the control group. The SSE program had a positive effect on fall-related fitness and BDNF levels.
痴呆症的风险随着年龄的增长而增加。为了降低这种风险，我们研究了方形踏步运动（SSE）对与跌倒相关的健康和脑源性神经营养因子（BDNF）水平的影响。韩国的 20 名老年人被随机分配到实验组或对照组（每组 n = 10）。参与者在有认证教练的指导下，每周进行两次，每次 70 分钟的 SSE，共 12 周。实验组参与者的平均年龄为 74.80 ± 6.763 岁，对照组为 72.50 ± 6.519 岁。实验后，实验组下肢肌肉力量明显提高（p < 0.01）。配对 t 检验显示实验组有显著改善（p < 0.01），交互效应有显著差异（p < 0.01），BDNF 水平也有显著改善。实验组 BDNF 水平显著提高（p < 0.05），对照组显著降低（p < 0.05）。SSE 方案对与跌倒相关的健康和 BDNF 水平有积极影响。
