## 4 Discussion  
The current study aimed to investigate the physiological (VO\({}_{2}\), RER, EE, MET, and HR) and perceptual (RPE and enjoyment) responses of five different AVGs, comparing them with each other and resting conditions. Another purpose of the current study was to evaluate and categorize the AVGs' PA intensities according to ACSM classification. The main findings demonstrated that AVGs examined in the present study significantly increased the VO\({}_{2}\), RER, EE, MET, and HR values compared to the rest condition in healthy and physically active college males and differed between each other. The highest values of VO\({}_{2}\), EE, MET, and HR were observed in Shape Up Cardio and Fighter Within AVGs. Based on the current study's findings and ACSM classification (light intensity PA is defined as requiring 2.0-2.9 METs, moderate as 3.0-5.9 METs, and vigorous as 6.0-8.7 METs) [35], the Fruit Ninja, the Just Dance, and the Shape Up Muscle AVGs were defined as moderate PA (3-6 MET), the Shape Up Cardio, and the Fighter Within AVGs were defined as vigorous PA (>6 MET). The highest enjoyment score was recorded for Fighter Within AVG. On the other hand, differently from the physiological findings of the current study, the highest RPE score was recorded for Shape Up Muscle AVG. There is strong evidence that AVGs increased physiological variables such as VO\({}_{2}\), MET, EE, and HR significantly, compared to the rest condition [20; 22; 30; 38; 40; 41; 42; 43] and sedentary routines [13; 43; 44]. Findings indicated that many factors, such as the number of players [22], types of the selected game [16; 25], features of the console used [42; 45], or the individual's ability to perform the desired skill [30], affect the physiological responses of AVGs. [PERSON] et al. [25] compared AVGs with two different exercise types and reported that the physiological responses (EE, VO\({}_{2}\), MET, and HR) of the \"Your Shape Fitness Evolve\" game were significantly higher than those the \"Kinect Adventures\" game. Consistent with these findings, AVGs played in the current study were found to be significantly different from each other. The current study aimed to evaluate and categorize the AVGs' PA intensity according to ACSM classification. In many studies, the AVGs' PA intensity has generally been defined as low (<3 MET) and moderate (3-6 MET) intensity [18; 40]. In the current study, based on the MET values, the Fruit Ninja, Just Dance, and Shape up Muscle AVGs can be defined as moderate PA, whereas the Shape up Cardio and Fighter within AVGs can be defined as vigorous PA. On the other hand, even though the AVGs with similar characteristics are compared (e.g., active video dancing games) in similar populations, the findings may differ because of the differences in game structure. [PERSON] and [PERSON] [30] examined the
