BACKGROUND
Falls prevention is a critical goal of training program for older individuals. This study explored the effects of a judo program on gait performance in older adults.
METHODS
Pre- and post-intervention (15 weeks, 1-hr session, twice a week) step length (cm), gait cycle time (s), speed (m·s-1) and cadence (step·min-1) mean values (AVG) and coefficients of variation (CV) were assessed in a judo (JG: N.=16 novice judoka; age=69.3±3.9 years) and a control (CG: N.=14 healthy older adults; age=70.1±4.5 years) group. Two 3 (motor complexity: flat, corridor, hurdling) ×2 (group: JG, CG) ×2 (time: pre, post) MANOVAs with repeated measures were applied to ascertain differences in gait parameters.
RESULTS
A significant Time×Motor Complexity×Group interaction was found for AVG and CV. For AVG, JG showed improvements for flat and hurdling conditions in step length (flat: ∆=+2.6%, d=0.4; hurdling: ∆=+3.2%, d=0.4), gait cycle (flat: ∆=-4.3%, d=0.4; hurdling: ∆=-4.0%, d=0.5), speed (flat: ∆=+6.6%, d=0.7; hurdling: ∆=+6.7%, d=0.6) and cadence (flat: ∆=4.3%, d=0.4; hurdling: ∆=3.9%, d=0.5). For CV, JG improved step length for flat (∆=-20.9%, d=0.6) and hurdling (∆=-16.3%, d=0.8) conditions, whereas CG showed a deterioration in the step length for the corridor condition (∆=+22.3%, d=0.7).
CONCLUSIONS
The findings demonstrated the effectiveness of an adapted judo program for improving gait performance in older individuals, suggesting a potential protective effect for fall risk.
背景
预防跌倒对于老年人的训练计划而言是一个关键目标。本研究探讨了柔道项目对老年人步态表现的影响。
方法
在柔道组（JG：N = 16名新手柔道运动员；年龄 = 69.3±3.9岁）和对照组（CG：N = 14名健康老年人；年龄 = 70.1±4.5岁）中，评估干预前和干预后（15周，每周两次，每次1小时课程）的步长（厘米）、步态周期时间（秒）、速度（米·秒⁻¹）和步频（步·分钟⁻¹）的平均值（AVG）以及变异系数（CV）。应用两个3（运动复杂性：平地、走廊、跨栏）×2（组：JG、CG）×2（时间：干预前、干预后）的重复测量多变量方差分析来确定步态参数的差异。
结果
在AVG和CV方面发现了显著的时间×运动复杂性×组的交互作用。对于AVG，JG在平地和跨栏条件下的步长（平地：∆ = +2.6%，d = 0.4；跨栏：∆ = +3.2%，d = 0.4）、步态周期（平地：∆ = -4.3%，d = 0.4；跨栏：∆ = -4.0%，d = 0.5）、速度（平地：∆ = +6.6%，d = 0.7；跨栏：∆ = +6.7%，d = 0.6）和步频（平地：∆ = 4.3%，d = 0.4；跨栏：∆ = 3.9%，d = 0.5）均有改善。对于CV，JG在平地（∆ = -20.9%，d = 0.6）和跨栏（∆ = -16.3%，d = 0.8）条件下的步长有所改善，而CG在走廊条件下的步长出现恶化（∆ = +22.�%，d = 0.7）。
结论
研究结果表明，一项经过调整的柔道项目对于改善老年人的步态表现是有效的，这表明对跌倒风险具有潜在的保护作用。
