Limited scientific evidence suggests that physical activity is directly related to cognitive performance in patients with chronic fatigue syndrome (CFS). To date, no other study has examined the direct relationship between cognitive performance and physical fitness in these patients. This study examined whether cognitive performance and physical fitness are associated in female patients with CFS and investigated the association between cognitive performance and physical activity level (PAL) in… 

Figures and Tables from this paper

Cognitive performance is of clinical importance, but is unrelated to pain severity in women with chronic fatigue syndrome

TLDR
Evidence is provided for the clinical importance of objectively measured cognitive problems in female CFS patients and a state-like measure (CFS Symptom List) appears to be superior over a trait-likeMeasure (CIS) in representing cognitive fatigue in people with CFS.

Can Recovery of Peripheral Muscle Function Predict Cognitive Task Performance in Chronic Fatigue Syndrome With and Without Fibromyalgia?

TLDR
Recovery of upper limb muscle function was found to be a significant predictor of cognitive performance in patients with CFS, suggesting that better physical health status could predict better mental health in patientswith CFS.

Exercise and Cognitive Functioning in People With Chronic Whiplash-Associated Disorders: A Controlled Laboratory Study.

TLDR
In the short term, postexercise cognitive functioning, pain, and fatigue were not aggravated in people with chronic WAD, however, randomized controlled trials are required to study the longer-term and isolated effects of exercise on cognitive functioning.

Physical activity measures in patients with myalgic encephalomyelitis/chronic fatigue syndrome: correlations between peak oxygen consumption, the physical functioning scale of the SF-36 questionnaire, and the number of steps from an activity meter

TLDR
This study compared three measures of physical activity in ME/CFS patients: the physical functioning scale of the SF-36, the number of steps/day (Steps) using an actometer, and the %peak VO 2 of a cardiopulmonary stress test.

Measuring the physical activity level and pattern in daily life in persons with chronic fatigue syndrome/myalgic encephalomyelitis: a systematic review

TLDR
The Chronic Fatigue Syndrome-Activity Questionnaire, CFS-AQ, Activity Pattern Interview and API are all equally capable of evaluating the physical activity level, but none of these are optimal to use.

Cognitive Performance Is Related to Central Sensitization and Health-related Quality of Life in Patients with Chronic Whiplash-Associated Disorders and Fibromyalgia.

TLDR
Significant cognitive deficits, signs of CS, and reduced health-related QoL in chronic WAD and FM patients compared to healthy individuals are demonstrated and provide preliminary evidence for the clinical importance of objectively measured cognitive deficits in patients with chronic Wad and FM.

Rebuttal to Ickmans Et Al. Associa- Tion between Cognitive Performance, Physical Fitness, and Physical Activ- Ity Level in Women with Chronic Fatigue Syndrome. J Rehabil Res

TLDR
This study found a substantially deteriorated physical exercise capacity in myal-gic encephalopathy/chronic fatigue syndrome and hypothesized that physical activity (PAL) is a potential mediator of the relationship between the exercise capacity (VO 2max) and cognitive function.

Poorer aerobic fitness relates to reduced integrity of multiple memory systems

TLDR
Data indicate that cardiorespiratory fitness may be important for the optimal function of neural networks underlying these memory systems, and an association between aerobic fitness and memory function such that individuals with lower cardiorean fitness exhibited poorer implicit memory performance and poorer long-term memory retention.

Effects of Short‐Term Exercise and Exercise Training on Cognitive Function Among Patients With Cardiac Disease

TLDR
This study provides evidence for the importance of CR in improving cognitive function in patients with cardiac disease and limited data are available concerning the effect of acute exercise and exercise training on cognitive function.

Strength and physiological response to exercise in patients with chronic fatigue syndrome

  • Medicine, Psychology

TLDR
Patients with CFS were weaker than sedentary and depressed controls and as unfit as sedentary controls, implying that physical deconditioning helps to maintain physical disability in CFS and that a treatment designed to reverse deconditionsing help to improve physical function.

Cognitive Dysfunction Relates to Subjective Report of Mental Fatigue in Patients with Chronic Fatigue Syndrome

TLDR
Findings show strong concordance between subjective complaints of mental fatigue and objective measurement of cognitive impairment in CFS patients and suggest that mental fatigue is an important component of CFS-related cognitive dysfunction.

Aerobic work capacity in patients with chronic fatigue syndrome.

TLDR
Patients with the chronic fatigue syndrome have reduced aerobic work capacity compared with normal subjects and patients with the irritable bowel syndrome and have an altered perception of their degree of exertion and their premorbid level of physical activity.

Symptom fluctuations and daily physical activity in patients with chronic fatigue syndrome: a case-control study.

Physiological responses during a submaximal cycle test in chronic fatigue syndrome.

TLDR
It is proposed that the reduced exercise tolerance in CFS is due to impairment in the mechanisms that constitute effort sense and/or to avoidance behaviors that result in a reluctance by these subject to exercise to full capacity.

Exercise capacity in chronic fatigue syndrome.

TLDR
Reaching the age-predicted target heart rate seemed to be a limiting factor of the patients with CFS in achieving maximal effort, which could be due to autonomic disturbances.

Exercise performance and fatiguability in patients with chronic fatigue syndrome.

TLDR
Raised perceived exertion scores during exercise suggest that central factors are limiting exercise capacity in patients with chronic fatigue syndrome.
