This study aimed to explore the combined effects of caffeine intake and listening to music on walking parameters, and its relationship with psychological variables (fatigue and exercise enjoyment) in middle-aged women.
Sixteen healthy middle-aged women, aged between 50 and 60 years old, participated in this study. Their walking parameters (distance, number of steps, steps number/minute, cadence and walking speed) were assessed using the 6-minute walking test (6MWT) in four task conditions: in no-music/no-caffeine, no-music/with caffeine, with music/no-caffeine, and with music/with caffeine conditions. Besides, exercise enjoyment and fatigue were evaluated using the Physical Activity Enjoyment Scale (PACES-8) and rating of perceived exertion (RPE) questionnaires, respectively.
As a result, we found that 100 mg of caffeine intake significantly (p < 0.05) improved walking parameters such as distance, cadence and number of steps during both simple (p < 0.05) and dual-task, while listening to preferred music, where optimal results were found (p < 0.01) with a large effect size (η2p >0.14). Listening to music was sufficient to significantly improve the distance (p < 0.001), cadence (p < 0.001), and walking speed (p < 0.05) values. Besides, both caffeine intake and/or listening to music significantly (p < 0.05 with large effect size (η2p >0.14)) decreased the feeling of fatigue and increased exercise enjoyment while walking in healthy middle-aged women.
In conclusion, caffeine intake seems to positively influence gait capacities, and its combined effects with listening to music, mainly preferred ones, would boost these beneficial effects in middle-aged women.
本研究旨在探讨摄入咖啡因和听音乐对中年女性步行参数的综合影响，以及其与心理变量（疲劳和运动愉悦感）之间的关系。
16名年龄在50至60岁之间的健康中年女性参与了本研究。在四种任务条件下，使用6分钟步行试验（6MWT）评估她们的步行参数（距离、步数、步频、节奏和步行速度）：无音乐/无咖啡因、无音乐/有咖啡因、有音乐/无咖啡因、有音乐/有咖啡因。此外，分别使用体育活动愉悦感量表（PACES - 8）和自觉用力程度（RPE）问卷评估运动愉悦感和疲劳程度。
结果发现，摄入100毫克咖啡因在简单任务（p < 0.05）和双重任务期间均能显著（p < 0.05）改善步行参数，如距离、节奏和步数，而听喜欢的音乐也有显著效果（p < 0.01），效应量较大（η2p > 0.14）。听音乐足以显著提高距离（p < 0.001）、节奏（p < 0.001）和步行速度（p < 0.05）值。此外，摄入咖啡因和/或听音乐在健康中年女性步行时均能显著（p < 0.05，效应量较大（η2p > 0.14））减轻疲劳感并增加运动愉悦感。
总之，摄入咖啡因似乎对步态能力有积极影响，其与听音乐（主要是喜欢的音乐）的联合作用会增强对中年女性的这些有益影响。
