Table 1: Opinion of survey participants on the potential of VR to support PA.  
classification of physical exercise intensity [32] shows that the students rated physical exercise as vigorous both with and without AWs (Figure 5). The Spearman correlation analysis between objective and subjective measures of exercise intensity indicated a significant (\(p<0.001\)) correlation between %HRmax and the RPE (6-20) scale for physical activity in VR without (r\({}_{\rm S}\) = 0.52) and with AWs (r\({}_{\rm S}\) = 0.53). Satisfaction with PA in Users Playing AVRG, Their Attitudes toward Virtual Active Entertainment, and Their Opinion of the Potential of VR to Support PA  
Based on the PACES survey (on a scale from 1 to 7), students rated PA while playing TRAVR Training Ops as high, regardless of whether they exercised without (6.15 \(\pm\) 0.81) or with loading (6.04 \(\pm\) 0.64). There were also no statistically significant differences in the evaluation made by users of either sex. Women rated the PA in VR without AWs at 6.15 \(\pm\) 0.69 points and with AWs at 6.03 \(\pm\) 0.67 points. For men, the results were very similar, with 6.15 \(\pm\) 0.94 and 6.05 \(\pm\) 0.63 points, respectively (Figure 6). Figure 4: Average time spent in individual HR zones by all students playing TRAVR Training Ops with and without leg loading: AWs—ankle weights; \(p\)—\(p\)-value; d—[PERSON]’s d; r\({}_{\rm fb}\)—Wilcoxon rank-biserial correlation coefficient. Figure 3: Intensity of PA while playing TRAVR depending on leg loading: AWs—ankle weights; \(p\)—\(p\)-value; d—[PERSON]’s d.  
The high rating of satisfaction with PA in users playing AVRG translates into their declaration of future use of VR technology for exercise (Table 1). When responding to the question \"With the right hardware and software, would you practice PA in VR?\", almost all respondents (62.3%) answered in the affirmative, with only two people (7.7%) having no opinion.
