Introduction: Trunk musculature is an important contributor to spinal stability. In a healthy population, ageing leads to generalised muscle volume loss. Whilst the benefits of synergistic muscle activity for a supported spine are well reported, age-related changes of relative muscle volume are less well-documented. Therefore, the aim of this preliminary study was to identify trunk muscle volume and ratio of flexors to extensors in a young and mature group of healthy participants.
