The Detrimental Effects of Mental Fatigue on Cognitive and Physical Performance in Older Adults Are Accentuated by Age and Attenuated by Habitual Physical Activity.
Objective: Our research objectives were to evaluate the extent to which cognitive and physical performance in older adults, when fresh, and when fatigued vary with age and habitual physical activity.
Methods: We employed experimental study designs, with between- (Study 1: age: 51-64 and 65-80 years and Study 2: habitual physical activity: active and sedentary) and within-participants factors (Study 1: test: before cognitive task and after cognitive task and Study 2: session: fatigue and control and test: before and after cognitive task). In testing sessions, participants performed exercise (6-min walk, 30-s sit stand, and 30-s arm curl) and cognitive (response inhibition and vigilance) tasks before and after a 20-min demanding cognitive task (time load dual back [TLDB] task). In Study 2, participants completed a paced breathing task (control session) as well as the TLDB (fatigue session). Ratings of mental fatigue and exercise-related perceived exertion were obtained.
Results: The 20-min TLDB task elicited a state of mental fatigue. Cognitive and physical performance was worse after than before the TLDB task. These impairments in performance were moderated by age (Study 1) and habitual physical activity (Study 2).
Conclusion: The deleterious effects of mental fatigue on cognitive and physical performance were accentuated by aging and attenuated by habitual physical activity.
Implications: Cognitive and/or physical training could mitigate the negative effects of mental fatigue on performance in older adults.
期刊介绍：
The Journal of Aging and Physical Activity (JAPA) is a multidisciplinary journal that publishes peer-reviewed original research reports, scholarly reviews, and professional-application articles on the relationship between physical activity and the aging process. The journal encourages the submission of articles that can contribute to an understanding of (a) the impact of physical activity on physiological, psychological, and social aspects of older adults and (b) the effect of advancing age or the aging process on physical activity among older adults.
In addition to publishing research reports and reviews, JAPA publishes articles that examine the development, implementation, and evaluation of physical activity programs among older adults. Articles from the biological, behavioral, and social sciences, as well as from fields such as medicine, clinical psychology, physical and recreational therapy, health, physical education, and recreation, are appropriate for the journal. Studies using animal models do not fit within our mission statement and should be submitted elsewhere.
