This study evaluated the relationship between daily physical activity (DPA) and memory capacity, as well as the association between daily activity and attention capacity, in college students in Taiwan. Participants (mean age = 20.79) wore wearable trackers for 106 days in order to collect DPA. These data were analyzed in association with their memory and attention capacities, as assessed using the spatial span test (SST) and the trail making test (TMT). The study showed significant negative correlations between memory capacity, time spent on the attention test (TSAT), calories burnt, and very active time duration (VATD) on the day before testing ( = -0.272, = -0.176, = 0.289, = 0.254, resp.) and during the week prior to testing ( = -0.364, = -0.395, = 0.268, = 0.241, resp.). The calories burnt and the VATD per day thresholds, which at best discriminated between normal-to-good and low attention capacity, were ≥2283 calories day, ≥20 minutes day of very high activity (VHA) on the day before testing, or ≥13,640 calories week, ≥76 minutes week of VHA during the week prior to testing. Findings indicated the short-term effects that VATD and calories burnt on the day before or during the week before testing significantly and negatively associated with memory and attention capacities of college students.
本研究评估了日常身体活动（DPA）与记忆能力之间的关系，以及日常活动与注意力能力之间的关系，对象为台湾大学生。参与者（平均年龄=20.79 岁）佩戴可穿戴追踪器 106 天，以收集 DPA 数据。这些数据与他们的记忆和注意力能力进行了分析，使用空间跨度测试（SST）和连线测试（TMT）进行评估。研究表明，记忆能力、注意力测试时间（TSAT）、消耗卡路里和测试前一天的非常高活动时间持续时间（VATD）之间存在显著负相关（= -0.272，= -0.176，= 0.289，= 0.254，分别），以及测试前一周内（= -0.364，= -0.395，= 0.268，= 0.241，分别）。消耗卡路里和每天的 VATD 阈值，可最佳地区分正常到良好和低注意力能力，为每天≥2283 卡路里，测试前一天≥20 分钟的非常高活动（VHA），或每周≥13640 卡路里，每周≥76 分钟的 VHA 在测试前一周内。研究结果表明，VATD 和测试前一天或前一周内消耗的卡路里对大学生记忆和注意力能力具有短期的显著负向影响。
