Impact of fatiguing exercise on corticospinal excitability and motor performance in young and older adults

LA Otieno - 2021 - digital.library.adelaide.edu.au
The impact of fatigue on corticospinal excitability and GABAergic inhibitory activity has been
relatively well studied in young adults. However, this is yet to be established in older adults …

Single joint fatiguing exercise decreases long but not short–interval intracortical inhibition in older adults

LA Otieno, JG Semmler, SK Sidhu - Experimental Brain Research, 2021 - Springer
Ageing is accompanied by neuromuscular changes which may alter fatigue in older adults.
These changes may include changes in corticospinal excitatory and inhibitory processes …

Stimulation of the motor cortex and corticospinal tract to assess human muscle fatigue

Older Adults Differentially Modulate Transcranial Magnetic Stimulation–Electroencephalography Measures of Cortical Inhibition during Maximal Single-joint Exercise

GM Opie, LA Otieno, M Pourmajidian, JG Semmler… - Neuroscience, 2020 - Elsevier
The effects of muscle fatigue are known to be altered in older adults, and age-related
changes in the brain are likely to be a contributing factor. However, the neural mechanisms …
