THE ACUTE EFFECT OF EXERGAME ON HAEMODYNAMICS RESPONSES IN SEDENTARY AND ACTIVE YOUNG ADULTS

Abstract

The purpose of this study was to investigate the effects of exergame (Nintendo^® WiiFi™) on haemodynamics responses. Twenty participants with age 18-25 years old were participated in this study and were divided into two groups; active group (AG; n=10) and sedentary group (SG; n=10).  On the experimental day, after resting for 10 min., participants performed exercise by using seven games of Nintendo Wii for 20 min. and recovery for 5 min. The haemodynamic variables including heart rate (HR), stroke volume (SV), cardiac output (CO), cardiac index (CI), ejection fraction (EF), and systemetic vascular resistance (SVR) were recorded in a real time on neck, sternum, rib closet to V6, and back by non-invasive technique (Physioflow^®) throughout the experiment. The results showed that at rest, during exercise, and recovery period, the participants in AG had better blood circulation than those in SG, but no significant difference between groups. However, the value of EF in AG at recovery period was higher than that in SG and showed significant difference (p<0.05) between groups. Therefore, exercise by exergame can improve the cardiac function in young adults. The AG had more responses to exergames than SG in some haemodynamics parameters.
