Although previous studies have shown that engaging in physical activity can elevate daily life satisfaction, few studies have identified the specific aspects that can result in this. This study examined whether enjoying moderate-to-vigorous intensity exercises with others for a longer time, but not any aspects of non-exercise physical activity, was associated with higher daily life satisfaction among older adults.
We conducted an intensive longitudinal diary survey of 182 individuals for 1 week and obtained valid data for 853 person-days. The time spent engaging in light and moderate-to-vigorous physical activity at 8:00-11:59, 12:00-15:59, and 16:00-19:59 h was measured using an accelerometer. Duration, intensity, timing, social context, and enjoyment of the exercises were assessed based on diary entries. Stratified by non-exercise and exercise days, we conducted multilevel models.
On non-exercise days, longer duration of light physical activity from 12:00 to 15:59 at the within-person level was associated with higher daily life satisfaction. On exercise days, longer duration of moderate-to-vigorous physical activity from 12:00 to 15:59 at the within-person level, longer exercise duration at the within-person level, exercising with moderate-to-vigorous intensity, and enjoyment of exercise at both the within- and between-person levels were associated with higher daily life satisfaction.
These findings indicate that enjoying moderate-to-vigorous intensity exercise for a longer duration than usual and engaging in non-exercise physical activity in the afternoon are important for elevating older adults' daily life satisfaction.
尽管先前的研究表明，进行体育活动可以提高日常生活满意度，但很少有研究确定能导致这种情况的具体方面。本研究调查了与他人一起较长时间享受中等至剧烈强度运动，而非非运动性身体活动的任何方面，是否与老年人更高的日常生活满意度相关。
我们对182名个体进行了为期1周的密集纵向日记调查，获得了853人日的有效数据。使用加速度计测量在8:00 - 11:59、12:00 - 15:59和16:00 - 19:59时段进行轻度和中等至剧烈身体活动所花费的时间。根据日记记录评估运动的持续时间、强度、时间、社交环境和愉悦程度。我们按非运动日和运动日进行分层，构建了多层次模型。
在非运动日，在个体层面上，12:00至15:59时段较长的轻度身体活动持续时间与较高的日常生活满意度相关。在运动日，在个体层面上，12:00至15:59时段较长的中等至剧烈身体活动持续时间、个体层面较长的运动持续时间、中等至剧烈强度的运动以及个体内和个体间对运动的愉悦感都与较高的日常生活满意度相关。
这些发现表明，比平常更长时间地享受中等至剧烈强度运动以及在下午进行非运动性身体活动对于提高老年人的日常生活满意度很重要。
