With continued energy training, there is an adaptation hypertrophy solely achieved by a rise in fibre measurement without an increase in the number of muscle fibres .
It is famous that there are normally no signs of degenerated fibres in ageing muscle and the fiber composition is comparatively fixed, i.e. unbiased of age. However, the muscle fibres per motor unit have been reported to extend, which is interpreted as a reduction in motoneurons.
