Abstract

Abstract The effect of associative and dissociative imagery was tested on a range of psychological-, physiological-, and performance-related variables during a progressive cycling task using a quantitative approach. Participants (n = 45) were randomly assigned to dissociative imagery, associative imagery, and no imagery conditions and performed a progressive cycling task at 10% above anaerobic threshold up to the point of volitional fatigue. Rate of perceived exertion (RPE), attention focus, and heart rate were monitored and assessed at 1-min intervals. Lactic acid (LA) accumulation was recorded at RPE = 5 (i.e. “strong effort”) and at the point of volitional fatigue. A series of repeated measures analysis of variance indicated that relative to their counterparts who were not using imagery, participants who used imagery accumulated higher levels of LA in blood. Despite some of the non-significant results, present effect sizes seemed to indicate that dissociative imagery may help decrease perception of effort, and associative imagery may help increase time on task.

意象对努力知觉和循环耐力的影响

在渐进式循环任务中，使用定量方法测试了联想和分离意象对一系列心理、生理和表现相关变量的影响。参与者(n = 45)被随机分配到分离意象、联想意象和无意象条件下，并在高于无氧阈值10%的条件下进行渐进式循环任务，直到意志疲劳点。每隔1分钟监测和评估感知运动率(RPE)、注意力集中和心率。乳酸(LA)积累记录在RPE = 5(即“强努力”)和意志疲劳点。一系列重复测量的方差分析表明，相对于没有使用图像的参与者，使用图像的参与者在血液中积累了更高水平的LA。尽管有一些不显著的结果，但目前的效应大小似乎表明，分离意象可能有助于减少努力的感知，而联想意象可能有助于增加任务的时间。

期刊介绍： The Journal of Imagery Research in Sport and Physical Activity is the first peer-reviewed journal devoted to research on the role of imagery in sport, physical activity, exercise, and rehabilitation settings. Imagery, also referred to as cognitive enactment or visualization, is one of the most popular performance enhancement and rehabilitation techniques in sports and physical activity. Journal editors Craig Hall (University of Western Ontario) and Sandra Short (University of North Dakota) are recognized leaders in the field, and the journal’s editorial board represents leading institutions in the U.S., U.K., and Canada. The single destination for all imagery-related research in sports and in physical activity, the Journal of Imagery Research in Sport and Physical Activity is an indispensable tool for scholars and practitioners of imagery, sports science, kinesiology, physical education, and psychology Criteria for publication will include: - Outstanding quality; likely to be widely read and highly cited; - Relevance to the area; - Contribution to the advancement of imagery research; - Interest to specialists in the field and accessible to researchers with interests outside the immediate topic of the paper; - Readability and presentation.
