CoreMoni: Individual Core Training Monitoring and Support System

ABSTRACT

Due to the influence of the new coronavirus, many people are interrupting fitness clubs and exercises/sports performed by multiple people. Under these circumstances, "core training," which can be easily performed indoors by individuals, attracts attention as an exercise to improve health. However, it isn't easy to recognize whether the posture during training is correct, significantly reducing effectiveness. This study developed 'CoreMoni,' a system to support individual core training, and verified its usefulness in supporting personal core training through evaluation experiments. We compared the duration of the correct posture of the plank with and without CoreMoni. The time spent on proper plank posture increased for 90% of the subjects. Besides, we used the System Usability Scale (SUS) and SUS's average score was 82 points, indicating that CoreMoni usability is excellent. Both quantitative and subjective assessments results suggest that CoreMoni supports individual core training by making users aware of posture and trunk vibration during core training.
