在对轻强度体力活动干预的二次分析中，我们假设老年癌症幸存者会自我选择更快的步行节奏来满足他们的日常步数目标。在41名参与者（年龄69 ± 3.1岁）中测量了干预前后7天佩戴ActivPAL监测器的平均步数/天和自由生活步行节奏。除峰值和平均步行节奏外，与步行强度相关的步进模式在20步/min的节奏带中分类，从40-59步/min（偶然运动）到≥120步/min（快速自发运动）。与等待名单对照组（n = 17）相比，干预组（n = 24）增加了他们的峰值30分钟步频（4.3 vs. 1.9步/分钟; p = 0.03），平均10分钟步频（4.1 vs. −6.6步/分钟; p = 0.04）和平均30分钟步频（5.7 vs. −0.8步/分钟，p = 0.03）。在表示中等强度体力活动（100-119步/分钟）的节奏带中，干预组和对照组每天的步数分别增加了478步（四分位距（IQR）：-121至1844），而减少了92步（IQR：-510至181）（p < 0.01）。对自由生活步行节奏和步行行为模式的评估可以为未来针对行为改变的干预提供信息，特别是在那些身体活动减少风险最高、易受移动性缺陷和丧失独立性影响的人群中。
In this secondary analysis of a light-intensity physical activity intervention, we hypothesized that older cancer survivors would self-select a faster walking cadence to meet their daily step goals. Average steps/day and free-living walking cadence were measured in 41 participants (age 69 ± 3.1 years) with an ActivPAL monitor worn 7 days pre- and post-intervention. Besides peak and average walking cadence, stepping patterns associated with ambulatory intensity were sorted in cadence bands of 20 steps/min from 40–59 (incidental movement) to ≥120 steps/min (fast locomotor movement). Compared to the waitlist Control group (n = 17), the Intervention group (n = 24) increased their peak 30-min cadence (4.3 vs. 1.9 steps/minute; p = 0.03), average 10-min cadence (4.1 vs. −6.6 steps/minute; p = 0.04), and average 30-min cadence (5.7 vs. −0.8 steps/minute, p = 0.03). Steps taken in cadence bands denoting moderate-intensity physical activity (100–119 steps/min) increased by 478 (interquartile range (IQR): −121 to 1844) compared to decreasing by 92 (IQR: −510 to 181) steps/day for the intervention and Control groups, respectively (p < 0.01). Evaluation of free-living walking cadence and patterns of ambulatory behavior can inform future interventions targeting behavior change, especially in those populations most at risk for reduced physical activity and vulnerable to mobility deficits and loss of independence.
