This study examined the impact of using bike desks on cognitive function and memory among university students. Physical activity during adolescence offers enduring health benefits, yet sedentary behaviors prevail among young adults, posing significant health risks. Bike desks, integrating stationary cycling with ergonomic desk designs, aim to mitigate sedentary behavior while enhancing cognitive performance. Research indicates that acute aerobic exercise improves executive functions, memory, and attention, which is particularly beneficial in educational settings. The study employed the verbal paired associates learning task (VPAT) to assess memory performance when either bike desk usage at moderate intensity (intervention) or rest (control condition) occurred before encoding and during early consolidation in 26 young adult medicine and nursing students in a library setting. We hypothesised that bike desk usage will enhance memory encoding and consolidation compared to the control condition of rest. The results of our study showed no significant differences in VPAT scores or response latency between seated and bike desk conditions. Supplementary analysis, including a multiple linear regression model (R2: 0.773, Adjusted R2: 0.651, p < 0.001) revealed that higher BMI, more frequent bicycle or stationary bike usage, and higher physical activity category were associated with improved VPAT performance with the bike desk, while higher vigorous MET minutes per week negatively impacted performance. This analysis suggests there are potentially numerous uncharacterized modulators of the impact of exercise on memory, warranting further research to identify and understand these factors.
本研究探讨了使用自行车办公桌对大学生认知功能和记忆力的影响。青春期的体育活动能带来持久的健康益处,但久坐行为在年轻人中普遍存在,带来了重大的健康风险。自行车办公桌将固定骑行与符合人体工程学的办公桌设计相结合,旨在减少久坐行为,同时提高认知表现。研究表明,急性有氧运动能改善执行功能、记忆力和注意力,这在教育环境中尤为有益。该研究采用言语配对联想学习任务(VPAT),在图书馆环境中,对26名青年医学和护理专业学生在编码前和早期巩固阶段进行中等强度的自行车办公桌使用(干预)或休息(对照条件)时的记忆表现进行评估。我们假设,与休息的对照条件相比,使用自行车办公桌将增强记忆编码和巩固。我们的研究结果显示,就座和使用自行车办公桌两种条件下的VPAT分数或反应潜伏期没有显著差异。补充分析,包括多元线性回归模型(R2:0.773,调整后R2:0.651,p < 0.001)显示,较高的体重指数、更频繁地使用自行车或固定自行车,以及较高的身体活动类别与使用自行车办公桌时VPAT表现的改善相关,而每周较高的剧烈代谢当量分钟数对表现有负面影响。该分析表明,运动对记忆的影响可能有许多未被表征的调节因素,需要进一步研究来识别和理解这些因素。
