AB - This paper discusses a novel use of vibration equipment to assess the safety of whether to pad or not to pad the vertically orientated walls within trampoline parks used specifically for an activity known as walk-the-walk. The CEN/TC 136 WG 17 is currently drafting EN ISO 23695:202x Trampoline Parks ? Safety requirements. The joint CEN/ISO Working Group is divided on whether to allow a padded or rigid vertical surface for the walk-the-walk activity. In general, all surfaces within the falling space of a forced movement device such as a trampoline shall be impact attenuated. This paper presents the finding of research undertaken by the University of Technology Sydney to provide the CEN/ISO Working Group with guidance. The walk-the-walk activity is where a trampolinist walks up a vertical wall using a high-performance trampoline to obtain sufficient vertical height and momentum.
