The objective of this pilot study was to evaluate a 6-month exercise program completed by 10 older Caribbean Americans. Assessments were done at baseline and 3 and 6 months, and included walks on an instrumented mat at preferred speed, and during street crossing simulations with regular (10 s) and reduced time (5 s). There were no significant differences on preferred walking speed over time. Differences between the street crossing conditions were found only at 6 months. Significant changes over time among the assessments were found only during street crossing with reduced time. Street crossing with reduced time was the only walking condition sensitive to capture changes associated with participating in the exercise program. There was a significant increase in dorsiflexion strength overtime. At 6 months it was significantly higher than at baseline and 3 months. The program was feasible, acceptable, and had some positive effects on walking, knee flexion, and dorsiflexion strength.
这项初步研究的目的是评估一项由10名年长的加勒比裔美国人完成的为期6个月的锻炼计划。在基线、3个月和6个月时进行了评估，评估内容包括在仪器化垫子上以偏好速度行走，以及在模拟过马路时分别以常规时间（10秒）和缩短时间（5秒）进行行走。随着时间推移，偏好步行速度没有显著差异。仅在6个月时发现了过马路条件之间的差异。仅在缩短时间的过马路过程中发现评估结果随时间有显著变化。缩短时间的过马路是唯一对捕捉与参与锻炼计划相关的变化敏感的步行条件。随着时间推移，背屈力量显著增加。在6个月时，背屈力量显著高于基线和3个月时。该计划是可行的、可接受的，并且对步行、膝关节屈曲和背屈力量有一些积极影响。
