## 3 Results  
The findings demonstrate that all AVGs significantly increased the VO\({}_{2}\), MET, EE, and HR above the rest condition (\(p<0.05\)). The lowest physiological responses were recorded for Fruit Ninja AVG; however, the highest physiological responses were recorded for Fighter Within AVG. The VO\({}_{2}\), EE, MET, and HR responses were not significantly different between Just Dance and Shape Up Muscle AVGs; also, they were not significantly different between Shape Up Cardio and Fighter Within AVGs. The physiological responses of participants for six different conditions are presented in Table 1. The values of total EE (kcal) for 15 min are presented in Figure 1. The perceptual responses of participants for different conditions are presented in Table 2. Percentage changes of VO\({}_{2}\) and HR according to resting values are shown in Figure 2. One of the objectives of the study was to categorize the AVGs' physical activity (PA) intensity according to ACSM classification. The Fruit Ninja, the Just Dance, and the Shape Up Muscle AVGs were defined as moderate PA (3-5.9 MET), and the Shape Up Cardio and the Fighter Within AVGs were defined as vigorous PA (6-8.7 MET). The categorization of the physical activity intensity of AVGs according to the ACSM classification is presented in Table 3. \begin{table}
