To examine the selective influences of changes in walking test capability on physical functional performance (COD speed, COD deficit, linear sprint speed, chair stand test, handgrip strength, and unloaded vertical jump) in community dwelling older women.
The performances of eighty women ((age, 64.7 ± 3.38 y; body mass, 66.3 ± 11.15 kg; height, 153.5 ± 5.71 cm, BMI, 28.08 ± 4.00 kg/m) were assessed in the 6-m walk test, timed up and go test, chair stand test, handgrip strength, and unloaded vertical jump. The change of direction velocity (CODv) deficit (m.s) was calculated as TUG velocity - 6-m walk velocity. Estimation statistics were adopted, which focus on the effect size of the higher/lower, as opposed to significance testing. The bootstrap with 5000 replicates was used to obtain bias-corrected and accelerated 95% compatibility intervals (CI) of the point estimate of each effect RESULTS: There were large effects between faster older women compared to slower older women in COD velocity (TUG), chair stand test, and CODv deficit. On the other hand, we observed no influence of 6-m walk test performance on vertical jumps or the handgrip strength test.
Strength and conditioning coaches and professionals involved with older women should consider the COD deficit (i.e., linear velocity minus change of direction velocity), as a complementary measure to provide an initial idea of the adequate pathway for exercise prescription and to track responses in older women.
研究步行测试能力变化对社区居住的老年女性身体功能表现（COD 速度、COD 不足、直线冲刺速度、坐站测试、握力和无负载垂直跳跃）的选择性影响。
对 80 名女性（年龄 64.7±3.38 岁；体重 66.3±11.15kg；身高 153.5±5.71cm，BMI 28.08±4.00kg/m）进行 6 米步行测试、计时起立行走测试、坐站测试、握力和无负载垂直跳跃测试。变向速度（CODv）不足（m/s）计算为 TUG 速度-6 米步行速度。采用估计统计，重点关注更高/更低的效应大小，而不是显著性检验。采用 5000 次重复的自举法获得每个效应点估计的偏置校正和加速 95%置信区间（CI）。
与较慢的老年女性相比，较快的老年女性在 COD 速度（TUG）、坐站测试和 CODv 不足方面存在较大差异。另一方面，我们观察到 6 米步行测试性能对垂直跳跃或握力测试没有影响。
力量和体能教练以及与老年女性相关的专业人员应考虑 COD 不足（即线性速度减去变向速度），作为补充措施，为运动处方提供初步思路，并跟踪老年女性的反应。
