Neurophysiological adaptation and responses to resistance exercise in healthy and neurologically challenged adult humans in relation to force steadiness

A force exerted by a muscle is not constant, but rather fluctuates about an average value. These force fluctuations, likely modulated by neural factors, are greater during lengthening contractions and in specific populations such as the elderly and individuals with pathological forms of tremor. The aging nervous system may have a greater difficulty modulating lengthening contractions and several changes within the nervous system associated with aging seem to support that. Furthermore, lengthening contractions are known to be differently modulated by the nervous system when compared to shortening and isometric ones. Whilst the evidence shows support for resistance exercise as a viable strategy to improve force steadiness, none of the available studies have explored training using lengthening contractions, which may have a greater potential for improvement.

The aim of Jakob’s Ph.D. is to provide the link between reduced steadiness of lengthening contractions and changes within the nervous system associated with aging. Furthermore, the aim is to explore lengthening contractions in a resistance training program to improve force steadiness in both the elderly and individuals with pathological forms of tremor.
