Health Promotion Community Support for Vitality and Empathy: Visualize Quality of Motion (QoM)

Today, the ratio of the lifestyle-related diseases has increased to approximately 30%, and Nation as well as people is getting more and more health-conscious. In particular attention has been made to core or trunk because it is key for injury prevention, sports progress, and beauty. And various training methodologies have been proposed to increase the muscle mass of the trunk. However, in the physical expression fields such as dance sport, the strength of the trunk is mainly influenced by smooth use of the trunk rather than its muscle mass. In this paper, in order to evaluate the use of the trunk twist movement, we propose two trunk torsion standard movements and a new trunk twist model. We also developed an evaluation application “Axis Visualizer” that score goes up when you twist the shoulders or hips smoothly with axis fixed and high frequencies. The aim of the application is to support trainers and coaches to visualize the use of customers’ trunk and to increase the training effect.
