Improving Cardiorespiratory and Muscular Function of Korean Firefighters

Abstract

Objective This study addresses declining physical fitness among Korean firefighters due to a low exercise participation rate caused by the absence of exercise instructors. The research explores Virtual Mate (VM), a Kinect-based mixed reality device, as a potential solution, but its capacity to replace training instructors in enhancing physical fitness remains uncertain. Methods Twenty Korean male firefighters were divided into two groups: the exercise group (EG) received an 8-week intervention using VM, while the control group (CG) maintained regular physical activity. Cardiopulmonary function and muscle function were measured. Results After 8 weeks, the EG demonstrated a significant improvement in VO2peak. Furthermore, there were notable enhancements in the strength and endurance of most knee, shoulder, and trunk flexors and extensors. Conclusions Integrating VM into an exercise program can effectively improve cardiorespiratory and muscular function in Korean firefighters.
