Open AccessCirculating testosterone and dehydroepiandrosterone are associated with individual motor unit features in untrained and highly active older men
Long-term exercise training has been considered as an effective strategy to counteract age-related hormonal declines and minimise muscle atrophy. However, human data relating circulating hormone levels with mo...

Adaptive certainty-based classification for decomposition of EMG signals
An adaptive certainty-based supervised classification approach for electromyographic (EMG) signal decomposition is presented and evaluated. Similarity criterion used for grou** motor unit potentials (MUPs) i...

Open AccessThe relationship between ciliary neurotrophic factor (CNTF) genotype and motor unit physiology: preliminary studies
Ciliary neurotrophic factor (CNTF) is important for neuronal and muscle development, and genetic variation in the CNTF gene has been associated with muscle strength. The effect of CNTF on nerve development sug...

Detection of motor unit action potentials with surface electrodes: influence of electrode size and spacing
A model of the motor unit action potential was developed to investigate the amplitude and frequency spectrum contributions of motor units, located at various depths within muscle, to the surface detected elect...
