Which Vo2 max or gait speed is more strongly associated with self-reported fatigue?
Best insight from top research papers
VO2 max is a measure of the maximum amount of oxygen that an individual can utilize during exercise. In the abstracts provided, there is no direct mention of self-reported fatigue being associated with VO2 max or gait speed. However, one study by Duffield and Bishop compared VO2, heart rate, and electromyographic responses to different running speeds and found that faster running speeds resulted in faster VO2 and heart rate responses, but there was no difference in amplitude or percentage of VO2 max attained . Another study by Billat et al. examined the VO2 slow component during intense running exercises and found that the time to exhaustion at a certain intensity was positively correlated with the critical velocity expressed as a percentage of VO2 max . These studies provide insights into the physiological responses to exercise but do not directly address the association between VO2 max or gait speed and self-reported fatigue.

Are there any studies investigating the association between perceived fatigue and VO2 max in healthy older adults?5 answersThere are studies investigating the association between perceived fatigue and VO2 max in healthy older adults. Egerton et al. found that fatigue was associated with clinically important reductions in daily physical activity levels of older people, and BMI, physical condition, and comorbidity were important factors in explaining the fatigue-physical activity association. Valentine et al. also found that adiposity was positively associated with fatigue, and physical activity was inversely associated with fatigue in older adults. Jones et al. found that insufficient activity levels were associated with fatigue in healthy older adults. Mänttäri et al. developed a prediction model for VO2 max based on the 6-min walk test (6MWT) results among healthy adults, which can be used to assess functional exercise capacity and predict cardiorespiratory fitness in older adults. Therefore, these studies suggest that there is an association between perceived fatigue and VO2 max in healthy older adults.
Does age affect the association between usual fatigue and VO2max?5 answersAge appears to have an impact on the association between usual fatigue and VO2max. Studies have shown that there is a linear loss of functional capacity with age, particularly in measures of muscle size and function. However, the decline in VO2max across ages seems to remain relatively constant up to 85 years. Additionally, cardiorespiratory training in older individuals has been found to be effective in increasing VO2max and compensating for age-related declines. On the other hand, a study found that VO2max was lower in older men compared to younger men, suggesting that physiological mechanisms other than blood volume may be responsible for this decline. Overall, while age may affect the association between usual fatigue and VO2max, the impact appears to be influenced by various factors such as muscle size, function, and cardiorespiratory training.
Is self-reported fatigue associated with VO2 max?5 answersSelf-reported fatigue is associated with VO2 max.
Is gait speed affected by mental usual fatigue?4 answersGait speed is affected by mental fatigue in older adults. Studies have shown that cognitive fatigue, induced by prolonged mentally demanding tasks, can lead to decreased gait speed and increased stride length variability in older adults. Additionally, experimentally induced mental fatigue has been found to impair gait performance during dual-task walking in older adults. These findings suggest that mental fatigue can have a negative impact on gait speed in older adults.
Is there an association between cardiorespiratory fitness and self-reported fatigue in middle-aged and older adults?3 answersThere is an association between cardiorespiratory fitness (CRF) and self-reported fatigue in middle-aged and older adults. Studies have shown that persistent fatigue is often reported in individuals with chronic musculoskeletal pain, and both chronic pain and chronic fatigue contribute to physical and cognitive decline in older adults. Additionally, a study found that low CRF is associated with increased likelihood of being diagnosed with metabolic syndrome (MetS), which includes fatigue as one of its components. However, there is no specific study that directly examines the association between CRF and self-reported fatigue in middle-aged and older adults.
Is VO2 max associated with self-reported fatigue in middle-aged and older adults?4 answersVO2 max is not directly mentioned in any of the provided abstracts. Therefore, there is no information available to determine if VO2 max is associated with self-reported fatigue in middle-aged and older adults.
