| Abstract |
Background: Although the effects of mental fatigue on cognitive-motor function and psychological state in young adults are well-documented, its effects in the elderly are not completely understood. The aim of this study was to estimate the effect of prolonged cognitive load on the indicators of psychological, cognitive, and motor functions. Methods: Fifteen young and 15 elderly men were asked to perform a 2 h "Go/NoGo" task. Psychological state (mood and motivation), cognitive (prefrontal cortex activity and cognitive performance), and motor (motor cortex excitability and grip strength) functions were measured before and after the task. During the 2 h task, both groups had a significantly similar increase in the number of "Incorrect NoGo" errors. Only in young men reaction time (RT) of "Incorrect NoGo" and intraindividual variability of RT of "Incorrect NoGo" significantly increased during task. After the task, handgrip strength decreased for the young men, whereas latency of motor evoked potentials prolonged both groups. Nevertheless, both groups indicated that they felt fatigue after the 2 h task; we observed that mental demand increased, whereas intrinsic motivation and mood decreased only in young men. Prolonged task decreased the switching/rest ratio of oxygenated hemoglobin for the young and the elderly men; however, greater for elderly than young men. Interestingly, the more the prefrontal cortex was activated before the 2 h task during the switching task, the fewer of "Incorrect NoGo" errors made by the young men and the greater the number of errors made by the elderly men. Conclusion: Because of the greater mental load and (possibly) greater activation of prefrontal cortex during the 2 h "Go/NoGo" task, there was greater mental and neuromuscular performance fatigue in young men than in elderly men. |

Attention Score in Context
This research output has an Altmetric Attention Score of 10. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 September 2018.
All research outputs
#3,551,804
of 25,385,509 outputs
Outputs from Frontiers in Neuroscience
#2,874
of 11,542 outputs
Outputs of similar age
#67,858
of 345,542 outputs
Outputs of similar age from Frontiers in Neuroscience
#79
of 244 outputs
Altmetric has tracked 25,385,509 research outputs across all sources so far. Compared to these this one has done well and is in the 85th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 11,542 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 11.0. This one has done well, scoring higher than 75% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 345,542 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 80% of its contemporaries.
We're also able to compare this research output to 244 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 67% of its contemporaries.
