Motor unit recruitment cannot be inferred from surface EMG amplitude and basic reporting standards must be adhered to

Letter to the Editor


The study by Jenkins et al. attempted to elucidate the mechanisms behind the findings of Mitchell et al. (J Appl Physiol 113(1):71–77, 2012). However, we believe the work of Jenkins et al. contains methodological issues, does not meet electromyographic reporting standards, and deduces conclusions beyond which can be interpreted from the data provided.
